What exactly is FOG?
Fats, oils, and grease, abbreviated as FOG, have become a rising global issue.
It has an impact on the efficiency of wastewater treatment facilities and industrial treatment units. In India, FOG-related concerns cause 47 percent of sanitary sewage overflows and more than 50 percent of sewer obstructions.
There is a need for effective FOG treatment options
Accumulation and solidification of fats, oils, and grease on sewage system walls causes pipe obstruction and clogging. It has a direct influence on the flow of wastewater, resulting in overflow problems. Toxic wastewater may contaminate neighbouring water sources and create environmental contamination, putting public health at risk.As a result, efficient FOG treatment technologies are urgently needed to keep wastewater treatment plants running.
Fats, oils, and grease, or FOG, enter the system through a variety of sources. Households, business enterprises, and factories, on the other hand, are key contributors of FOG. In most cases, FOG is a by-product of the cooking process in the home. Sewer obstructions are also frequently observed as a result of cooking oil and fats being discarded in the kitchen sink.
Commercial enterprises offering food services, such as hotels, restaurants, and cafés, are especially affected by FOG concentration. In terms of industries, food processing and industrial activities have the ability to create a large amount of fats, oils, and grease.
Why is FOG a problem in waste water treatment?
FOG build-up in the system is aided by a fast-expanding metropolitan population, an increase in the number of food outlets, and faulty sewage networks. FOG build-up on the drain surface and in the pipes causes clogging and overflow issues. It can also cause other problems like as odour, bug infestation, and contamination of the land, water, and air. Furthermore, it can erode drain pipes, necessitating costly repairs.
Fats, oils, and grease present a wide range of difficulties in wastewater treatment facilities owing to their delayed breakdown process and high BOD need. Treatment plants in the food processing industry become overburdened, resulting in expensive operational and treatment expenses.
FOG may account for 25-35 percent of the total chemical oxygen demand in raw sewage that feeds into municipal treatment plants. It may also result in:
- Clogging of the system, lowering and restricting capacity.
- Increase in the amount of time necessary for pipe cleaning and maintenance.
- If FOG is not removed adequately from incoming waters, it depletes the surface of oxygen.
- To manage extra FOG, the wastewater facility requires additional energy and capacity.
- It has the potential to impair the performance of microorganisms that feed on sludge, lowering effluent quality.
Other industrial issues are as follows:
- Filament Issues with Nocardia
- High TSS in effluent
- Sludge volume has increased
Is Netsol capable of resolving the FOG problem in WWTP?
Bioremediation has developed as a viable and efficient biological approach for the elimination of FOG in wastewater treatment facilities. Lipase-producing microbial strains can successfully break down fat triglyceride molecules. Microorganisms, in addition to lipase, create bio-surfactants, which aid in the bio-degradation of fats, oils, and grease by allowing the bacteria to proliferate more efficiently. The selected microbe strains strive to break down FOG as quickly as possible while also reducing scum. Furthermore, rancidification of FOG is prevented, resulting in the elimination of odours caused by build-up.
Netsol Water is a market leader in water treatment facilities and is actively working on all sophisticated solutions.
