When considering reverse osmosis (RO) for water treatment, there are several things that should be taken into account. One of the most important things to consider is the quality of the water to be treated. RO is widely used to remove harmful inorganic contaminants; however, due to the limitations and higher operating cost, pretreatment of the water may be necessary. For example, hardness minerals are common in groundwater, and at high levels, pretreating with a softener is often recommended.

WQHC to offer free pH and chlorine test strips again this year

As Memorial Day approaches, heralding the summer pool season, a new survey on swimmer hygiene conducted by the Water Quality & Health Council (WQHC) finds that although most (93%) say they would never reuse someone else's bath water, almost seven in 10 (68%) admit they do not always shower before getting in the pool. Failing to shower before swimming adds contaminants to the pool that can lead to unhealthy swimming conditions.

Performance Testing for Media & Systems

The most common question from customers of water treatment systems utilizing adsorbent media is, “How long will the media/system perform?” The most common answer may be a number of months or years but should be more elaborative than a mere number. The most honest answer is, “It depends on the water chemistry.”
