Activated Carbon Filters

Product Description

AquaPoint GM & GM5 series automatic backwashing deep bed granular media filters are designed for stringent general purpose water and wastewater filtration. These single and multi-unit filter assemblies are ideal for the removal of sediment, turbidity, color, total suspended solids (TSS), biochemical oxygen demand (BOD) and total organic carbon (TOC).  Filtration performance is dependent on specific application characteristics however < 5 micron particle size and > 90% total suspended solids removal is commonly achievable.

The filters continuously process forward flow until differential pressure, elapsed time or manual operation initiates a backwash sequence to purge the filters of accumulated solids. The automatic backwash function utilizes a portion of the clean filtered water produced by the system to scour and clean the media bed. Where applicable, air scour may be used to enhance the backwash process. The fully adjustable backwash timer is typically set for a 3 minute cycle.

GMF & GMF5 series media filters feature fiberglass reinforced plastic (FRP) corrosion resistant vessels, durable stainless steel skids, schedule 80 PVC face piping, thermoplastic composite diaphragm valves and automated controls. Feed and backwash pumps may be field installed submersible pumps or pre-installed skid mounted centrifugal pumps. All units are fully assembled and factory tested prior to shipping. Flanged inlet and outlet connections make installation and start up easy and efficient.
