High hydraulic loads, insufficient tank depth and poor settling behaviour of the activated sludge are the most common causes for the poor performance of secondary clarifiers. Frequently, secondary clarifiers are even unable to reliably ensure the solids retention required. Under storm conditions for example, the amount of filterable solids can be up to three to four times the volume experienced under dry weather conditions. Overflow of flocks increases COD, BOD and phosphorus loads in the effluent and receiving watercourse with the result of higher wastewater fees. Our RoDisc® Rotary Mesh...

WASTE WATER Solutions as the blinding process progresses. When the predefined maximum pressure differential has been reached, the solids are removed automatically from the filter surfaces. The solids are removed by the slow rotation of the filter discs combined with spray nozzle bars which wash the filtrate through the mesh from inside to outside without the need to use fresh water. The spray water and the solids contained are collected in a trough and discharged axially from the machine. The filtration process runs on continuously whilst the filter discs are being cleaned.
