Aqua MegaDiskTM

Aqua MegaDiskTM is a large disk filtration system that has been developed for very high flow rates.

The filter cloth is mounted on the plastic segments, 8 of which form a filter disk with up to 24 disks per filter module. Each disk has a filtration area of 10 m², with 24 disks, this represents a filter area of 240 m² per unit. The filter disks are fully immersed in the effluent therefore 100% of the filtering surface is used. The maximum hydraulic capacity of a Aqua MegaDiskTM filter is: 2400 m3 / per day / per filter disk.

The water flows through the filter cloths, into the segments, passing into the central collection tube. From here it passes to the riser chamber before exiting over the outlet level control weir, all by gravity. Backwashing takes place on level and time, with backwash water coming from the centre tube and being discharged at 10 m head to the return activated sludge lane or the head of the works.

During normal operation, with increasing solids deposition on the filter cloth, the hydraulic resistance of the filter system, and thus the level difference between raw and clean water level rises. At a level difference of 25 cm the cleaning of the filter is triggered. The filter disks are rotated slowly, and the deposited solids are removed by the suction device, without the filtration process being interrupted. Any settled solids in the filter tank are removed using the built in sludge pumps provided with every filter assembly.
