Household fat
Not so long ago, such a device as a fat manter or fat separator, as they are also called, could only be found in large kitchens, where the installation of such equipment was simply necessary. A lot of dishes are washed in public catering establishments, school and production canteens per day. Therefore, a huge amount of fats enters the sewer, which tend to harden at a temperature below 30 ° C. And if these fats are not separated from wastewater before entering the sewer system, then in a rather short time they will stick to the walls of the wastewater and bring the sewer system to the non-working state.
