Treated Water
Because fat is lighter than water, it pops up inside the barrel and slowly accumulates in its upper part, or in specially arranged at the top of the technical capacity of the wells and the water after settling goes down the drain. Pop-up inside the barrel oil solidifies and grows layers down – in time for the water, there are fewer places, cleaning efficiency naturally decreases. To support the work of grease, it is necessary to periodically relieve him from the accumulated fat. Both purification method have similar disadvantages: low efficiency of sewage treatment, lack of utilization of natural (biological oxidation) of fat mass in static traps, and very intense odors caused by rot fat mass, the need for frequent pumping and transport collected fat, highly hindered due to freezing and hardening of fat. After removing the cover grease can feel and the result of putrefactive processes in the fat-filled tank – the smell, from which it is difficult to get rid of a few hours. Low degree of purification of waste water from the fat leads to that part of the fat together with the waste water still gets into the sewers – the fat sticks to the pipe surface, reducing the capacity of the pipeline, year after year, the company at the same time can be fined for exceeding the normative content of fat in the treated sewage discharged into wastewater. Yes, and the need to periodically collect and export, fat mass, too, can not be attributed to the facilities.
