[...]Retention of filterable solids from the secondary clarifier effluent Reduction of phosphorus by upstream precipitation Preliminary filtration in drinking water recovery from surface waters and in UV disinfection applications 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. Overflow of flocks increases COD, BOD and phosphorus loads in the effluent and receiving watercourse[...]

[...]Reliable separation of solids from wastewater Low headloss due to the large effective bar rack surface High screenings discharge capacity Well-proven design based on the RakeMax® principle The RakeMax® HF is a L-shaped multi-rake bar screen and like the RakeMax® screen belongs to the MAX family of HUBER screens. This screen has a flat and therefore hydraulically advantageous bottom section that transitions into a steep conveying section. This combines the benefits of the well proven RakeMax®, reliable solids separation and high screenings discharge capacity, with a low headloss due to a big [...]
