AquaDisk Cloth Media Filter
Aqua-Aerobic Sysmems Inc.
The AquaDisk Cloth Media Filter is a wastewater treatment technology that uses cloth disks as an alternative to granular media filtration.
The AquaDisk Cloth Media Filter is a system that arranges disks of cloth media for tertiary filtration. The systems are available in arrangements of either six or twelve disks, and the media is chlorine resistant. Powered by a PLC control system, the filter operates in three phases: filter mode, backwash mode, and solids wasting mode. Filter mode involves sending water through the system where solids accumulate on the cloth media. Backwash mode cleans disks, and solids waste mode pumps waste to a collection area.

The surface area of each cloth media filter disk is 323 cubic feet, with a hydraulic loading of 3.25 GPM/ft2 (ADF). Both packages (6-disk and 12-disk) were designed to optimize wastewater treatment; the 6-disk unit operates at an average capacity of 1042 GPM, while the 12-disk unit enables a flow of 2084 GPM.
Additional replacement cloth media filter disks can be purchased from the manufacturer.
The manufacturer specifies performance targets related to high solid and hydraulic loading rates, low hydraulic profile and backwash rates, and low life-cycle cost.
The systems must be maintained properly and backwashed consistently to ensure optimal filtration and that the discharged clean water is safe to use.
As a tertiary filtration system, the AquaDisk must be coupled with a primary filtration system to initially remove solids and substrates from the wastewater.

The filtration systems are evaluated based on the average flow rate they accommodate, the frequency of maintenance and cleaning, and the level of particle removal efficiency by the cloth filtration media.
