Genetic Research Facility Will Reap the Benefits of Installing All Stainless-Steel Condensate Polisher

The unit will reduce the amount of iron deposits the facility was experiencing in their boiler tubes, which prolongs the life of the tubes and provides significant long-term fuel savings.

Greensand Filters Shipped to Western PA Water Plant

A western Pennsylvania, small private water utility, recently received four greensand filters to replace the filters that were failing.  Unable to get the original manufacturer to provide new, duplicate units, our customer found our website. 



Four New Greensand Filters and Greensand Media Ready for Shipment to Water Utility



Because of State regulations, the systems and their operation needed to be as close to the original as possible, otherwise new permits would be required.  Since Greensand is in very, very short supply, the media was changed to Greensand Plus from the same manufacturer.  Sodium hypochlorite is used to continuously oxidize dissolved iron in the water coming into the filters.  Also, these filters are very unique because they are much shorter than we normally manufacture.  Our normal tank straightside is 60".  These tanks are 36" straightside.
