SUPERIOR SOLUTIONS FOR MEDIA FILTERS

High Efficiency Media Filters

Process Cooling Systems High Efficiency Media Filters are configured for either manual or automatic backwashing of the filter bed and are self-contained to provide efficient particulate filtration on systems with high particulate loading. Each filter includes a pump, motor, basket strainer, backwash valves, filter vessel and required controls for either manual or automatic backwashing of the filter bed. All components are rated for outdoor use, are factory assembled with interconnecting piping, and include UL listed electrical. Standard filters are configured for process water backwash but are available configured with city water backwash.

BASE:

High Density Polyethylene Pallet with 4 Way Access 3.6” Fork Slots and Grated Top

PUMP:

Self-priming pump complete with brass volute, pump shaft, and open-faced bronze impeller. Pump will be close coupled to a TEFC motor.

MOTOR:

TEFC, NEMA56 Industrial Frame motor. This motor offers consistent power to promote superior water circulation and filtration, safety feature protecting unit from overload, and a standard drip proof seal to minimize seal burnout and provides for easy maintenance. UL Recognized; CSA Certified. 3 Year Warranty.

STRAINER:

5” Brass Strainer with 2” NPT Connection Point. Unit will come complete with a 5” pump basket, brass pump lid, gasket seal and bronze tee handles with stainless steel studs.

FACEPIPING:

Manual Backwash: Brass piping assembly complete with influent / effluent pressure gauges (0-60 PSI liquid filled), brass interconnecting piping between pump discharge and valve assembly, Schedule 80 PVC filter vessel inlet and filter vessel outlet piping.

Automatic Backwash: Brass piping assembly complete with filter vessel pressure gauge (0-60 PSI liquid filled), brass interconnecting piping between pump discharge and valve assembly, Schedule 80 PVC filter vessel inlet and filter vessel outlet piping.

VALVES:

Manual Backwash: 3-Way manual bronze body ball valve with PTFE seals. Valves will be connected together with a mechanical linkage and a common actuator handle.

Automatic Backwash: 3-Way On/Off forged brass nickel-plated body, 304 stainless steel ball and stem, PTFE seats, L-port, 24-240 VAC, and NEMA 4 rating with Fail Safe actuator.

FILTER VESSEL:

Filter vessel consisting of an inner shell of fiberglass reinforced polyester resin wound over with fiberglass filament. The unit features an inflow diffuser for even distribution of the water flow across the filter bed, and hydraulically balanced PVC internal laterals to maximize water flow and filtration. The filter vessel is fitted with a manual drain fitting, large filter base for stable floor mounting and a manual pressure relief valve. The filter vessel is rated for 50 psi maximum allowable working pressure.

MEDIA:Silica Filter Sand

CONTROLS:

Manual Backwash

Automatic Backwash:

Automatic Backwash Control Panel
NEMA 4 Rated
Motor Starter with Overload and Short Circuit Protection
Transformer to convert primary supply to 24 VAC control power for the valves
Through the door disconnect
HOA switch for pump motor
Differential pressure switch mounted on backside of control panel.
System Alarm Package
Motor Overload Trip, Backwash (Pressure switch activated twice in a 6 hour period), Modulating Valve Fault, and Pressure Switch Fault Alarms

NOTE: Backwash from external water source (City Water Configuration) includes controls modification to stop pump during backwash. Installing contractor responsible for flow control valve, pressure regulator (maximum 30 psi) and/or backflow preventer, if required. Backwash flow rate, must be no less than 75% and no greater than 100% of the filters designed maximum GPM.
