Res-Kem recently shipped a 52 gpm dual tank greensand filter to a Westchester County New York corporate headquarters campus. This filter uses greensand to remove dissolved and precipitated iron and manganese from the water coming from the local public water system.

At a Westchester County corporate headquarters campus, about 4 to 5 times a year, our customer experiences water quality and quantity problems. The campus receives its water from a local public water supplier. High levels of iron and manganese are present within the public water distribution system, and peak flow events such as hydrant flushing or firefighting activities have caused brown water to be drawn into their water system. What exacerbates the problem is the campus is at the end of the water distribution system without looping.
Therefore, iron and manganese laden sediment accumulates the piping and is drawn into the campus drinking water system. Res-Kem designed and constructed a filtration system to remove iron and manganese from the drinking water, as well as a storage tank. The volume of the tank is 150,000 gallons which provides two days of storage in the event of a water emergency with the water supply.
