Plant based natural coagulants

They are also mentioned as blood thinners. This effect occurs because they are substances that block the coagulant effect of vitamin K. Anticoagulant plants can very be appropriate in phytotherapy to treat or prevent the onset of anomalies, such as thrombi or blood clotsdue to poor blood supply as a result of excessive platelet aggregation.

For example, the use of these plants may be appropriate to remedy conditions in which blood flow should be more fluid as heart attacksangina pectorisarteriosclerosisetc.

Summary sheet of the main anticoagulant medicinal plants. They should not be combined with each other or with drugs that have the same effect because there is a risk of bleeding. Any mismatch in the dose of anticoagulants can cause a lack of clotting and therefore heavy bleeding that can be fatal.

For this reason, you should always consult a doctor before taking any of the following plants:. Other times it may be counterproductive to use some of these plants in people who are prone to ailments caused by a lack of clotting and nose bleedinghematomasetc. Within this group are some plants such as willow thinners, garlic, onions, thyme, rosemary, ginseng and licorice. It is necessary to consider that the use of remedies that contain anticoagulants is not recommended before and after surgical procedures because they can increase bleeding from the wound.

The reason lies in the ability of extracts of this plant to dilate blood vessels and cause blood to flow more smoothly. It seems that flavonoids exert a vasodilating action on the walls of arteries and capillaries while prevent platelets settle within blood vessels.

This property can be applied to treat a number of diseases the reason of which lies in poor circulation. Teas or capsules as suggested in the patients leaflets. Ginseng, because it contains antiplatelet and vasodilatory components improves blood circulation to maintain the capillaries clean and dilated.

Willows have been used and are still being used as an alternative to aspirin aspirin. Aspirin relieves pain and inflammation and it is used as a blood thinner. Aspirin was produced initially from this plant and from meadowsweet Filipendula ulmariafrom wintergreen Gaultheria sp. And from some species of birches Betula spp. See contraindications.

Not for use in combination with drugs for circulation. This means that you should not combine these plants with other remedies for circulation or blood-thinning medications. The use of anticoagulant plants can also be counterproductive in people who are prone to diseases caused by a lack of clotting such in frequent bleeding nosebruisesetc. Besides those mentioned above, many other plants that may have anticoagulant effects. Among the most common are those rich in coumarins.

Coumarins block vitamin K preventing thrombin formation coagulation factor IIawhich is required to clot is formed. It should not be combined with drugs that have the same effect. Not to be combined with blood-thinning medications. Do not use with drugs that have the same effect. However its usual use is not recommended because it causes intestinal dependence as a laxative.

Some plants with anticoagulant properties have other properties that make them equally suitable to prevent bleeding, because they have bioflavonoids that increase the elasticity of the capillaries, as is the case of bioflavonoids from citrus lemonsorangestangerines, etc. This antagonistic effect of different food components indicates that food can modify or enhance the effect of plants and thinning medications.

Oily wastewater treatment, and effective separation of liquid and solid matter in wastewater, requires effective water treatment chemistries. Chemistry that is natural and offers a low use cost is the best solution for this challenge. Industrial wastewater is one of the largest sources of water pollution. Large amounts of fresh water are used as a raw material during production processes wherein intermediate products and wastes are mixed with the water resulting in process water that must be treated before discharge or reuse.

Explore our case studies to see how Brennfloc has successfully completed many wastewater treatment projects in a variety of industries. Centralized waste treatment facilities treat wastewater from a variety of industries. Much of the wastewater contains very high pollutant concentrations, which are extremely difficult to treat, such as emulsified oil. Industrial processes frequently subject oil to chemical and mechanical action causing it to be dispersed into the water.

This emulsified oil does not simply float on the surface of the water and must be removed using more intense treatment techniques. Download Now. Solid and liquid separation water treatment is necessary to prevent the build-up of solids in wastewater systems.

Suspended solids, dissolved solids and colloidal solids contained in industrial effluent must meet requirements before being discharged. In the food and beverage industry, wastes are commonly biodegradable and non-toxic, however, there are usually high concentrations of biochemical oxygen and suspended solids, surfactants, antibiotics and growth hormones, and oils and fats incorporated in the water, creating the need for a complex treatment process.

A large oil refinery in the US committed to safety, the environment, and continuously improving supplier performance standards was faced with the challenge of increasing environmental performance and cutting costs for coagulant use in their wastewater processing units.

This refinery has five different coagulant applications as part of its wastewater processing. Inthe refinery was challenged with the following: loss of a process water tank, a drive to improve environmental results at the wastewater treatment plant, and better cost control for the coagulant used throughout the refinery. The coagulant used at the PSO and IGF units was identified as an application where improvements in cost and performance could be made.

Process water is used in industrial plants, industrial processes and production facilities following extensive water pretreatment such as softening or demineralizing.Flocculation and coagulation treatment chemicals are used in effluent water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering.

Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping colloids apart.

Water treatment coagulants are comprised of positively charged molecules that, when added to the water and mixed, accomplish this charge neutralization. Inorganic, organic, or a combination of both coagulant types are typically used to treat water for suspended solids removal. When an inorganic coagulant is added to water containing a colloidal suspension, the cationic metal ion from the coagulant neutralizes the negatively charged electric double layer of the colloid.

Examples of ChemTreat coagulation products include aluminum salts, iron salts, and polyelectrolytes. Flocculants gather the destabilized particles together and cause them to agglomerate and drop out of solution. Examples of ChemTreat flocculants include low- medium- and high-molecular weight polymers. For certain water sources, organic coagulation is more appropriate for solid-liquid separation.

Organic coagulant is generally used when sludge generation is desired. Furthermore, blended organic and inorganic chemicals are often more effective than either organic or inorganic chemicals alone. The correct blend can often combine the advantages of using the inorganic coagulant sweep-floc mechanism with the sludge generation characteristics of the organic coagulants.

These are the most widely used classes of organic coagulation chemicals. They function by charge neutralization alone, so there is no advantage to the sweep-floc mechanism. Polyamines are also effective in treating many types of wastewater. These all-organic polymers act similarly to the inorganic coagulant products in that they not only coagulate the colloidal material in the water, but also contribute their own precipitated floc.

This sweep-floc precipitate readily adsorbs organic materials such as oil and grease. The precipitate generally dewaters to low moisture concentration, making this choice of coagulant particularly well-suited to unit operations that generate hazardous sludge, such as DGF and IGF units in oil refineries.

This self-precipitating chemistry is generally significantly more expensive to use than inorganic coagulant chemistry, but it can be economical when sludge removal and disposal costs are factored in. Inorganic coagulation is both cost-effective and applicable for a broad variety of water and wastewater.

Inorganic coagulant treatment is particularly effective on raw water with low turbidity total suspended solids concentration and will often treat this type of water when organic coagulants cannot. Once added to water, inorganic coagulant chemicals react with the alkalinity and hydrate to form metal aluminum or iron hydroxide precipitates, which act as a sweep-floc mechanism.

This mechanism can be compared to snowfall on dirty air. As the snow falls, it adsorbs particulates in the air, which coprecipitate, thus cleaning the air.

In water treatment, the metal hydroxide sweep-floc acts on water the way a snowfall acts on air. Many difficult-to-treat colloidal suspensions can be effectively treated using inorganic coagulants. Although the metal hydroxide precipitate sweep-floc is advantageous in water cleaning, these precipitates add to the overall sludge volume that must be treated and removed.

These precipitates also tend to lower the overall density and dewaterability of sludge versus precipitates created with organic coagulants. For influent or raw water applications where the sludge is generally non-hazardous, the penalty for creating more sludge with higher water content is small.

For wastewater applications with hazardous sludge, the economic penalty can be significant. Alum is mildly hazardous with similar health effects and corrosion characteristics as diluted sulfuric acid. It is manufactured as a liquid, and the crystalline form is dehydrated from the liquid. Alum is one of the most commonly used water treatment chemicals in the world.Your body has a way of protecting you from bleeding. There are times when blood clots can be dangerous.

These conditions and heart valve replacement surgery increase the chance of developing life-threatening blood clots that may cause a heart attack or stroke.

Blood thinners lower your risk for heart attack and stroke by decreasing the chance that blood clots form. There are also some ingredients found in nature that some believe help reduce the risk of clotting.

You may want to talk to your doctor about the following natural remedies that have been reported to help thin the blood. Never take these natural remedies instead of or with your prescription blood thinning medication without first talking to your doctor. According to a study, one of its main active ingredients, curcumin, acts as an anticoagulant. It works to inhibit coagulation cascade components, or clotting factors, to prevent clots from forming.

Shop for turmeric. Ginger is in the same family as turmeric and contains salicylate, a natural chemical found in many plants. Salicylates are found in plants. They are derived from salicylic acid. Acetylsalicylic acid, synthetically derived from salicylate and usually called aspirin, can help prevent stroke and heart attack. Foods with salicylate, such as avocadossome berries, chilies, and cherriesmay also keep blood from clotting. Shop for ginger. Cinnamon and its close cousin, cassiaare both widely available and contain coumarina chemical that, in certain drugs, acts as a powerful anticoagulant.

Cinnamon and cassia may also lower blood pressure and relieve inflammation caused by arthritis and other inflammatory conditions.

Use caution when using cinnamon as a blood thinner. A risk assessment showed long-term cinnamon consumption in foods, including cinnamon-based breads and teas, can cause liver damage. Cayenne peppers can have a powerful blood-thinning effect on your body because of their high levels of salicylates. They can be taken in capsule form or easily ground up as a spice for food. Shop for cayenne peppers.

Vitamin E has been reported to be a mild anticoagulant. Shop for vitamin E supplements. If you have cardiovascular, or heart and blood vessel, disease, or if you want to help prevent it, your doctor may recommend a heart-healthy diet.

A heart-healthy diet includes fresh fruits and vegetables, percent whole grains, healthy oils, low- or no-fat milk products, and healthy proteins. A heart healthy diet limits high-fat, high-cholesterol, and high-sugar foods. This best diet for your overall health. Too much vitamin K in your diet may lessen the effectiveness of Coumadin.

Green leafy vegetables, such lettuce and spinach, and other vegetables such as broccoli and brussels sprouts are high in vitamin K.In this study, four plant-based natural coagulants banana peel powder, banana stem juice, papaya seed powder and neem leaf powder were evaluated for the removal of turbidity, chemical oxygen demand COD and total suspended solids TSS from municipal wastewater.

The experiments were conducted at room temperature without adjusting the initial pH. The maximum turbidity removal was observed with banana peel powder Papaya seed powder and banana stem juice were the most effective for TSS removal Interestingly, all the natural coagulants tested in the study did not change the pH of the wastewater, which is an added advantage.

FTIR analysis of banana peels revealed that functional groups such as carboxylic acid, hydroxyl and aliphatic amines might be responsible for promoting the coagulation—flocculation by neutralizing the charge on impurities in water.

Overall, the results suggest the potential of low-cost natural coagulants in municipal wastewater treatment. The online version of this article Coagulation is a physical—chemical process to remove turbidity of drinking water and wastewater.

Though chemical coagulants are effective in wastewater clarification, their use is not sustainable. Generation of excessive non-biodegradable sludge is the major issue of using chemical coagulants for wastewater treatment Carvalho et al.

An alternative greener and sustainable approach is use of natural coagulants for turbidity removal. Natural coagulants from plant-based materials or renewable sources are attracting a lot of attention due to their various advantages over chemical counterpart.

They are biodegradable Asrafuzzaman et al. Since they produce lesser sludge with high nutritional value Choy et al. Despite these advantages, natural coagulants are not commercialized so far except few such as Moringa oleifera seeds Choy et al. Challenges in harvesting and processing of natural coagulants from plants might be the major factors limiting their commercialization.

Waste or non-useful materials such as orange peel, banana pith and neem leaf powder have also been utilized as natural coagulants Anju and Mophin-Kani ; Kakoi et al. However, most of these natural coagulants have been tested on synthetic wastewater.

The main objective of this study is to evaluate the coagulation potentials of banana peel powder, banana stem juice, papaya seed powder and neem leaf powder for the treatment of municipal wastewater. Banana Musa acuminate stem and neem Azadirachta indica leaves were either collected from field or purchased from local market. The raw municipal wastewater used in the study was collected after the preliminary treatment fine screening from sewage treatment plant STPlocated near Doon University, Dehradun.

The wastewater was characterized in terms of pH 7. The banana peels were cut into small pieces and washed thoroughly with tap water to remove any external dirt.

The dried banana peels were grinded to fine powder using mortar pestle. The banana stem juice was prepared as per the methodology reported by Alwi et al.

The powder obtained after grinding the banana peels, papaya seeds and neem leaf was sieved with a mesh of size 0. The purpose of high-speed mixing was to evenly distribute the coagulant, while the slow speed mixing was used to keep floc particles uniformly suspended in the water Alwi et al. The experiments were conducted at room temperature and the pH of the wastewater was neither adjusted before the experiment nor controlled during the experiment.

All the experiments were performed in duplicates. The turbidity and pH of the wastewater, before and after jar test, were measured using the nephelometer and pH meter, respectively. Closed reflux method was used for COD analysis. The maximum coagulation activities turbidity removal efficiencies of banana peel powder 0. It is clearly evident from Fig. It is observed that high dosage of coagulant had negative impact on the coagulation activity.

Similar results were obtained with papaya seed powder and neem leaf powder Fig. Wastewater treatment by natural coagulants.Blood-thinning agents, also known as anticoagulant medications, are used to treat a number of medical conditions. These medicines prevent the formation of blood clots, which can cause a heart attack, stroke or another serious health problem. A variety of natural substances also have blood-thinning effects, including some common foods and nutritional supplements.

However, these substances should not be used as a substitute for prescription anticoagulant medication.

The authors of a March summary article published in "JAMA Internal Medicine" report that garlic has been found in some studies to exert a mild inhibitory effect on platelet aggregation -- one of the initial steps in blood clot formation.

Other studies, however, have found that garlic does not have blood-thinning effects when taken alone at daily recommended doses.

The authors of a May article published in "Critical Reviews in Food Science and Nutrition" examined all of the published medical studies to date evaluating medical uses of garlic. They concluded that there is insufficient evidence to determine whether garlic may be useful for the prevention of blood clots.

However, it may have blood-thinning effects when taken in large amounts or potentially boost the effects of anticoagulant medications. Further research on the potential blood-thinning properties of garlic is needed. EPA and DHA act as blood thinners by inhibiting the formation of substances that promote blood clot formation. Fish oil supplements are available in capsule and liquid forms, and dosages vary by manufacturer. The American Heart Association notes that research data support daily consumption of 0.

This equates to about 2 servings of fish weekly.

Vitamin E inhibits blood clot formation through a variety of mechanisms -- at least in the laboratory. These blood-thinning effects appear to be dose dependent, meaning the effects may not be significant at low concentrations.

More research is needed to determine whether there is a potential role for vitamin E as a natural blood thinner and, if so, to establish effective dosage recommendations. Vitamin E is found in a number of foods, including whole grains, wheat germ oil, almond oil, sunflower oil, egg yolks, seeds and nuts. The commonly prescribed blood-thinning medication warfarin Coumadin is a derivative of a naturally occurring, plant-derived chemical called coumarin.

Evaluation of plant-based natural coagulants for municipal wastewater treatment

More than 3, different coumarins have been found in a wide assortment of plants, fungi and bacteria. However, very few coumarins exert anticoagulant effects, which are typically very weak. It is a common misconception that coumarin-containing herbs have comparable blood-thinning effects to the medication warfarin -- which is not true.

In fact, no substantial evidence supports use of plant sources of coumarin as effective, safe blood-thinning agents. Nonetheless, many doctors recommend that people on prescription blood thinners avoid coumarin-rich herbs to avoid possible additive effects. Examples include angelica root, arnica flower, anise, chamomile, fenugreek, licorice root, parsley and red clover.

Discuss your medications, supplements and dietary choices with your healthcare provider as they might interact or have additive effects when combined with blood-thinning medications. Do not stop taking your prescription anticoagulant medication or replace it with natural products without first consulting your healthcare provider.

Although many natural substances have blood-thinning and clot prevention potential, research is needed to clarify the possible interactions, effective forms and dosages before standardized health recommendations can be made for use of natural blood thinners.
