Suggestions for effective methods of treating grease in wastewater

Grease, although an indispensable product in the food processing process, is a major harmful agent to wastewater treatment systems. When discharging directly into drainage systems without treatment, grease can cause blockages, reduce the efficiency of treatment technologies, and even damage equipment, seriously affecting water quality and the living environment. Join BioFix Fresh to learn some  popular solutions to treat grease in wastewater today to minimize the harm they cause.

Causes of grease in wastewater

Grease in wastewater arises from daily activities in households, restaurants, hotels such as food handling, cooking, washing dishes, etc. In addition, the production activities of food processing factories such as rice vinegar oil, chocolate, etc. also discharge grease into the environment. After a long time of accumulation, they cling to the water treatment system, causing blockages, foul odors, and polluting the environment.

Most restaurants, eateries, and hotels are now equipped with grease separation tanks and grease pits to minimize the amount of grease entering the wastewater. However, during holidays and peak seasons, a large amount of fat discharged if not treated in time will enter the fat pit, another amount of grease enters the wastewater system, harming the wastewater treatment system behind and also affecting the environment.

The role of grease treatment in wastewater

Grease in wastewater, if not treated, will lead to many serious problems for the wastewater system such as:

• Pipe blockages: Grease is lighter than water and is insoluble in water. When entering the wastewater treatment system, they will harden and adhere to the pipe walls, gradually forming dense layers, causing pipe blockages. This leads to wastewater overflowing, causing environmental pollution and affecting the daily life of many families and the business of restaurants, eateries, and hotels.

• Reduced efficiency of wastewater treatment systems: Large amounts of grease accumulation will hinder the growth of beneficial microorganisms, reducing the ability of organic matter to decompose in wastewater. This leads to the formation of fibrous bacteria, sludge that is difficult to settle and causes foam in the wastewater treatment system.

• Causing equipment failure: In addition to causing blockages, excess grease also affects equipment such as pump propellers, paddles, garbage barriers, air blower discs of chemical lighters,...

• Causing environmental pollution: Wastewater containing grease is discharged into water sources such as rivers and lakes, polluting water sources, harming human health and aquatic organisms. When grease seeps into the soil, it also affects crops and groundwater.

Grease in wastewater causes many negative effects. Therefore, the treatment of grease in wastewater plays an extremely important role in ensuring the efficiency of the wastewater treatment system, protecting the environment and human health.

Methods of treating grease in wastewater

There are many methods for treating grease in wastewater. In which, the most commonly applied methods are: oil separation method, use of chemicals, use of microbial preparations. Learn the characteristics of each method with BioFix Fresh.

Treatment of grease in wastewater by oil separation method

The grease separation method by grease treatment tank is very commonly used. This method has a simple principle: grease is lighter than water, so it will float on the surface. The wastewater is fed into the grease treatment tank, the leftover food and sediment will settle to the bottom of the tank, and the grease will automatically surface and be collected.

Using an oil separation tank has the advantage of being easy to operate and not affecting the environment. However, the effect will depend on many factors such as the amount of grease and the settling time. After a while, the business owner has to spend a significant amount of money to suck out the grease periodically.

Treatment of grease in wastewater with chemicals

Using chemicals to treat grease in wastewater brings quick results. However, this method does not bring long-term results, grease can re-adhere and continue to cause blockages. In addition, the use of chemicals causes environmental problems, human health, and pipeline damage.

Treatment of grease in wastewater by grease microorganisms

Fat-eating microorganisms are microorganisms that are able to break down grease into harmless substances such as CO₂ and water. This method is considered environmentally friendly and highly efficient, long-term in treating hard-to-decompose greases. However, microbiological treatment is usually slower than other methods.

What method should be applied to treat grease in wastewater

Each method of treating grease in wastewater that BioFix Fresh has just analyzed above has its own advantages and disadvantages. However, in order to bring sustainable efficiency and reduce pressure on the wastewater treatment system behind and at the same time increase the beneficial microflora, fat treatment with microbial preparations is recommended by many experts.

Treating grease in wastewater with fat-eating microbial preparations is a solution recommended by many experts. Natural microorganisms have the ability to eat fat in an environmentally friendly manner. They grow and multiply in numbers over time, providing long-term effects without affecting the wastewater treatment system.
