Commercial

Northwest Water Treatment, Inc. provides equipment for various commercial water treatment applications. Water softening for boilers, and seawater filtration are applications where we have extensive experience. Our commercial water treatment equipment can be customized to fit your specific needs. Listed below are equipment used in standard applications.:

Softening systems suitable for applications ranging from 60,000 to 1,200,000 grains of hardness removal, at flow rates from 10 to 200 gallons per minute, with 1", 1-1/2", 2", and 3" valves available.

Twin alternating softening systems for continuous soft water applications such as boilers, car washes, and laundromats. Suitable for conditions ranging from 22,500 to 360,000 grains removal at flow rates from 13 - 35 gallons per minute.

Multi-Media Filters for filtering applications consist of four different layers of media, with coarse material on the top of the bed to remove the largest particles, and successively finer layers deeper in the bed, where smaller particles are removed. These filters typically remove sediment as small as 10-15 microns.

Greensand Filters for removing iron and manganese from water through oxidation and filtration, where no chemical regeneration is required. In addition to backwashing, greensand filters must be regenerated with a potassium permanganate solution. The solution is automatically introduced into the filter as a part of the regeneration cycle, or is injected into the raw water with a metering pump, prior to entering the filter.

Activated Carbon Filters are utilized to remove chlorine, and reduce color, organics, tannin, and objectionable tastes and odors from water.

Note: All standard softening and filtering systems utilize Fleck control valves.

Chemical Feed Systems by Walchem Corporation are used as a component to disinfection or filtration systems. Available with pumping output controlled manually, or proportional to water flow.

Ultraviolet Sterlizers manufactured by Wedeco.
