Biotechnology of wastewater treatment and disposal of grease waste food businesses. Today, with c increasing food production, expansion of public power more acutely expresses himself as a problem of utilization used cooking oils and fats. In order to imagine its size is sufficient to note how quickly the household consumes a bottle of sunflower oil, and multiply the result by the number of city residents. It is not dumped in septic tanks, and sometimes in conventional reservoirs. Cafes, restaurants, and food industries, inevitably in its productive activities are faced with the problem of waste water from oil and utilization of fatty wastes. Depending on the scale daily volume of waste removed in fat mass can vary from a few kilograms to several tons.
Saturated fats and solids wastewater water must necessarily be cleaned before being discharged into drains. The most common method of wastewater from oil today is a mechanical flow grease trap, which acts on the principle of detention of a pop-up fat with the help of the system partition, set across the flow of waste water. Ali Partovi has many thoughts on the issue. The water runs, not hitting, and pop-fat remains on the partitions in the form of a dense mass that is necessary collect, remove and dispose of. Another weapon in the arsenal against fat is weakly running the storage tank (grease separators, static trap). In fact, this is a common barrel, or a cascade of several buried in the ground casks, which are accumulated and defended fatty waste water for at least 1 day (usually for a longer period of time – from 3-4 per diem runoff to a week).
