biological oil removal catalytic enzyme is an environmentally friendly product that can decompose fats, oils and fats (FOGs). This product does not contain any chemicals harmful to the earth.

In essence, the products of biological oil removal catalytic enzymes are the blends of various super catalytic enzymes, which can decompose fats, oils and greases into water and carbon dioxide.

grease is a by-product of cooking. Usually, the sources of grease include: food residue, meat fat, lard, butter, edible oil, butter, margarine, sauce, gravy, seasoning, fried food, baked goods, cheese and butter. According to the color saturation of carbon chain, grease can be solid or viscous liquid. Oils and fats are lipids composed of fatty acids, triglycerides and fat-soluble hydrocarbons, which are few but important components of oils and fats.

Floods are caused by sewer blockage, and grease blockage is a worldwide problem. With the solidification and precipitation of grease on the inner wall of sewer, the pipeline is blocked, thus limiting the flow of sewage, and the continuous grease will reduce the capacity of sewer system. With the passage of time, the sewer blocked by oil will collapse, resulting in the overflow of sewage; This sewage may eventually enter the country's water source in the form of pollutants. Blockage and sewer flooding may lead to other environmental problems inside and outside the site.

Oils and fats are usually produced in food processing plants, restaurants, houses and slaughterhouses. By dumping directly into the sewer or entering the sewer system through the oil-water separator usually installed in restaurants. The oil-water separator is designed to capture most of the grease in restaurant sewage and separate it from the sewage before reaching the sewage pipeline. However, the efficiency of oil-water separator depends largely on its maintenance frequency. In addition, if the dishwasher or high-temperature water is used to wash dishes, the grease will melt and emulsify in the wastewater, thus escaping the filtration of the oil-water separator and then flowing into the sewer. The grease will solidify, forming a pipeline where particles are deposited on the surface, thus blocking the flow of wastewater. Stoll and Gupta found that the concentration of oil in wastewater from Asian restaurants in Thailand ranged from 731 to 1111 mg/L. These large amounts of grease come from the wastewater of fast food restaurants. The menu of these restaurants is mainly composed of fried chicken, seafood, French fries and salad dressing, which contains a lot of oil.

at present, there is only one way to control the generation of grease. This method includes installing an oil-water separator, which separates oil from restaurant sewage and reduces its concentration in wastewater. Recently, good management measures have been implemented in restaurants and food service institutions to ensure the correct disposal of residual grease. In addition, some companies have reached agreements with restaurants to collect second-hand cooking oil and use it to produce biodiesel. As a solution to the blockage of sewage pipes, sewage treatment cities use high-pressure water jets to remove grease from sewage pipes, while shovels and screens are used to collect grease from sewers manually. The collected oily sediments are treated as solid waste in the landfill. This causes more environmental problems, because FOG greatly reduces the conductivity of soil. In addition, the biological oxidation of high-concentration oils will release carbon dioxide and methane into the atmosphere.

Pretreatment of restaurant wastewater with in-situ enzyme can prevent clogging and premature aging of drainage area.

Oils and fats are mainly by-products of cooking, including food residue, meat fat, lard, tallow, cooking oil, cream, margarine and sauce.

The fat, oil and grease released into the sewer will block the sewer and block the water flow, leading to the flood surge during heavy rain.

clogged sewers can also attract rodents and other pests, which can spread diseases. Dining places are one of the main causes of river pollution.
