Clarifier
Biological water from tanks carrying activated sludge flowing into the center tube of the sedimentation tanks, waste water is distributed evenly over the entire cross-sectional area throughout the clarifier, residence time of about 2-3 hours. Tank is designed so that the water in the tank with slow speed, while the cotton residue has formed a large enough proportion of the flow velocity win wastewater passes through settling tanks will settle to the bottom. Waste water from the clarifier has decreased 70-75% COD.
The surface water from sedimentation tank focused on collecting trough then flows naturally through pools of sterilization, disinfection and chemical dosing pumps are pumping in.
the bottom of the tank sediment submersible pump circulating pump is on aerobic biological tank to replenish the mud under horizontal sedimentation tank wastewater through, to stabilize the sludge microorganisms in an aerobic biological, improve fruit processing.
the excess sludge from the settling tank is discharged into the stands periodically mud reservoirs.
