Standard Features

Industrial FRP Tank Automatic Water Softener is sized on the basis of two different parameters, i.e.: Exchange capacity, that is the quantity of water delivered between regenerations, and Maximum Flow Rate, which is the maximum quantity of water requited at any peak usage period. Exchange capacity depends upon the amount of ion exchange resin in the softener and upon the quantity of salt used for resin regeneration. Maximum flow rate is an important datum in case of non-continuous water delivery. It is measured in gallons per minute (GPM).

  • The FRP mineral tank is engineered for a 150 psi working pressure and is tested to 200 psi. It is equipped with a manhole in the upper dome.
  • A premium grade sulfanated nonphenolic polystyrene type resin is contained in the mineral tank. The resin will deliver 30,000 grains per cubic foot when brined at a rate of 15 lbs. per cubic foot.
  • The brine tank is a combination of high density polystyrene brine measuring tank and a brine valve, including an air eliminator valve and a safety brine refill shut off to prevent tank overflow.
  • The automatic regeneration controller features a choice of 7 or 12 day calendar wheels. Time of regeneration and length of time for each regeneration cycle are fully adjustable.
  • The automatic regeneration controller features a choice of 7 or 12 day calendar wheels. Time of regeneration and length of time for each regeneration cycle are fully adjustable.
  • The under drain utilizes either a hub & lateral or a header & lateral system to evenly distribute water and prevent resin loss, and to insure minimal pressure drop at peak flow rates.

Commercial Water Softeners PWC 150S

Standard Features

The PWC-150S Series water softener is designed specifically to remove high levels of dissolved solids that create “hard water” conditions, principally Calcium and Magnesium. These systems have a very high operating capacity, which make them ideal for most commercial and industrial applications.

Advantages of Water Softeners Include:

Reduction of Scaling and Fouling in downstream Piping, Plumbing, and Equipment

Protect Reverse Osmosis (RO) Membranes from Scaling and premature replacement

Reduced cost of Chemicals, especially Detergents by increasing their effectiveness

Water Softener Operating Cycles:

Service Cycle: Decreases water hardness via ion exchange. The water flows through the Ion Exchange Resin and is softened. In the process, the Ion Exchange Resin gradually looses effectiveness as it gives up its sodium or potassium ions and must be “Regenerated.”

Backwash Cycle: As with carbon and multimedia filters, when the softener begins to clog or when the head loss (pressure drop) though the resin bed increases, flow rates are reduced. To prevent solids “break through“ and the resulting degradation of water quality, the Service Cycle flow is reversed, fluidizing the resin bed. The reverse flow is directed, by the control valve(s) to drain, carrying with it, any particulate matter that has built up during the Service Cycle.

Regeneration Cycle: Depleted Softener Ion Exchange Resin is easily regenerated in a bath of salt brine. The Control Valves on most Softeners manage this by filling a separate “Brine Tank”, which contains bulk salt crystals, with water creating a source of Salt Brine. The Control Valve then draws this brine into the Softener Tank to regenerate the Ion Exchange Resin.

Rinse Cycle: After Regeneration, the Ion Exchange Resin Bed is rinsed of brine to prepare the Softener for another Service Cycle.

Continuous Versus Periodic Service: In most operations, demand for process water is tied to work shifts. If those work shifts consume all 24 hours each day, and the demand for process water is constant, the Softener system may need to be designed to operate in stages across multiple tanks, so that the Backwash, Regeneration, and Rinse Cycles can occur in one or more tanks while the other tanks are operating in the Service Cycle mode. If the demand for process water is periodic, Backwashing, Regeneration, and Rinsing can usually occur during off hours, which decreases the size and complexity of the Softener Filtration system. Our standard products are designed to accommodate either scenario up to 400 gallons per minute; however, specific applications may require additional design modifications.

Industrial

Industrial Water Softeners are designed to meet the demands of high flow rates and are often configures with controls and flow paths that enable full time use, without service interruptions. In many cases, units are paired to allow a one-running/one-on-standby operating mode to insure a reliable flow of softened water. Industrial may also provide a means of interoperability with other equipment or downstream processes.
