Calculation of Sand Areas and Bunker of Wastewater Treatment Institutions

The sand trapped in the sander at the wastewater treatment plant is removed using hydraulic elevators, and then the sand is removed by sandblasters (pulpers) to specially prepared sand fields. The sand area is a carded area surrounded by 1-2 m high earthen walls (valleys). The size of the area, the layer of dumped sand is taken at the rate of 3 m3/m2 per year, and dried sand is removed from time to time.
