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.

A New Use for DNA

Protecting public health by providing safe drinking water to citizens served by community water systems is and will always be a serious concern of government agencies, public water suppliers and private industry around the world. There is a growing need to make the onsite testing of these water supplies easier and more reliable to detect and assess contamination in a timely manner to shorten the harmful health effects of heavy metals in drinking water.

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.”

Water Quality in Majority of U.S. Well Networks Remains Unchanged Over Decades

USGS analysis examined concentrations of chloride, dissolved solids and nitrate in groundwater

There was no change in concentrations of chloride, dissolved solids or nitrate in groundwater for more than 50% of well networks sampled in a new analysis by the U.S. Geological Survey (USGS) that compared samples from 1988 to 2000 to samples from 2001 to 2010. For those networks that did have a change, seven times more networks saw increases as opposed to decreases.

Test Package

The Complete RO Screen was developed with input from membrane manufacturers and treatment professionals. This package tests for most factors that can reduce the life of an RO membrane. Due to the nature of RO produced water, the testing was designed to provide lower detection levels. This test package is also beneficial for other applications that require pure water. New and improved compact packaging will reduce shipping costs.

Achieving Accuracy

There are many portable handheld devices that measure dissolved solids, but not all instruments are equal. Beyond the product specifications, how can you tell which instrument to choose? Even when you choose the best instrument, how can you get accurate repeatable readings? This article addresses design and use issues that affect the accuracy of conductivity, resistivity and total dissolved solids (TDS) measurements so that you choose the right instrument for your application and use it correctly.
