Filter Mode - Inlet wastewater enters the tank or basin, completely submerging the cloth media. By gravity, liquid passes through the cloth media. As solids accumulate on and within the media, a mat is formed and the liquid level in the tank or basin increases. The filtered liquid enters the internal portion of the disk where it is directed to final discharge through the center shaft.
Backwash Mode - At a predetermined level or time, the backwash cycle will be initiated. Solids are backwashed from the surface by liquid suction from both sides of each disk. During backwash, disks are cleaned in multiples of two, unless a single disk unit is utilized. Disks rotate slowly, allowing each segment to be cleaned. Backwash water is directed to the headworks. Filtration is not interrupted during this cycle.
Solids Wasting Mode - The filtration process requires no moving parts. Heavier solids are allowed to settle to the bottom portion of the filter tank. These solids are then pumped on an intermittent basis back to the headworks, digester or other solids collection area of the treatment plant.
The AquaPrime cloth media filtration system is designed as an economical and efficient solution for the treatment of primary wastewater and wet weather applications. This system utilizes a disk configuration and the exclusive OptiFiber PF-14® pile cloth filtration media to effectively filter high solids waste streams without the use of chemicals. This system is ideal for primary wastewater treatment and wet weather applications due to its proven removal efficiencies and high quality effluent, even under varying influent conditions.
The AquaPrime system is designed to handle a wide range of flows in a fraction of space compared to conventional primary clarifiers. The system’s high solids removal in comparison to conventional treatment provides energy and operational savings within the wastewater treatment plant due to reduced loads to the secondary process or more solids for anaerobic digestion (energy harvesting).
Aqua-Aerobic Systems is well-known throughout the wastewater treatment industry for its complete lineof pile cloth media filtration systems including the original AquaDisk® and AquaDiamond® filters. The tradition continues with the AquaDrum filter featuring OptiFiber® pile cloth media. This filter is designed to provide economical treatment of smaller flows, particularly where driving head is limited. The AquaDrum filter can be utilized for any tertiary treatment application.
The AquaMB Process® is a multiple barrier system that integrates biological treatment and clarification with dual barrier filtration consisting of cloth media and external membrane separation. It is ideal for wastewater plants that require optimum performance and flexibility at the lowest cost of ownership. Compared to multiple unit processes and membrane bioreactor (MBRs), the AquaMB Process offers numerous advantages with the added benefit of single source responsibility.
