System is unassembled (for shipping purposes) and includes
all necessary valves, tank, grades of media, underbedding, internal distributors/strainers, drain line
flow controls, and the clock/timer/stager assembly mounted into a control box. External piping is not
included. Customer may want to consider system additions of pressure gauges, sample cocks, vacuum breakers,
flex connectors, bypass valves,
Cast Iron Valve available connections: (FPT: 1.5 inch, 2 inch, 2.5 inch, 3 inch); (Flanged: 3 inch, 4 inch, 6 inch)
Plastic Valve available connections: (MPT: 1.5 inch); (Male Spigot Weld: 1.5 inch, 2 inch); (Female Socket Weld: 2 inch); (Flanged: 2 inch, 3 inch)
Recommended Service Flow Rates/Ranges are based on the cu.ft. of the tank/filter bed. Slower flow rate per cu.ft. = Better Filtration
System Flow Rates as listed are based on pressure drop curves of less than 2 psi drop through the service valves.
Backwash Rates for proper bed cleaning are best achieved at 14 gpm per sq.ft. However, water temperature variation may require backwash rate adjustment. Valve sizes, pipe sizes, pump sizes, water availability, and unique applications also allow service flow and backwash variations.
Backwash Rates allow 40% bed expansion @ 60°F.
Backwash Flow Restrictors are included and can be provided to accommodate any desired backwash flow rates.
Valve Sizes and Tank Size Pairings for special flow rates and backwash rates may be substituted at customer request or are application dependent. SWT GAC carbon filters use 8 x 30 mesh bituminous coal-based granular activated carbon. Acid washed carbons, and coconut shell carbons are available on request. 12 x 40 or 20 x 50 mesh carbons are also available.
Operating Pressure: 150 psi (10 bar)
Maximum Temperature: 140°F (60°C)
