As the public becomes more health conscious and educated about water contamination, demand for bottled water continues to increase. In order to provide purified water, it is important to understand the reverse osmosis (RO) water purification process.
Pretreatment is the first step in a reverse osmosis system for high quality water.
A recent federal court decision may have created an opportunity for relief from United States Environmental Protection Agency (EPA) rules that impose costs that substantially exceed benefits.

The following interview is with Robert Huehmer, who currently is process manager with USFilter?s (a Vivendi Water company) Memcor, Microfloc and General Filter products division, located in Timonium, Md.
The when, where and how treatment is applied.
When faced with upgrading or searching for alternative methods, the staff of one facility had to determine if their belt filter presses were still a cost-effective solution for their solids dewatering process.
Exfiltration system uses distribution chambers to protect sensitive Lake Erie
Extracting the maximum benefit from condensate polishing systems continues to be a top priority among many electric utility plants. With cost reduction pressures and increasing water quality standards, owners and operators continue to evaluate the resin handling procedures that affect corrosion product transport and contaminant ion impurity levels.
Performance studies show that crushed recycled glass can provide capital and annual cost savings over traditional sand filter media.
This article defines what organoclays are and details how they are being used to remove oil and grease from wastewater.
When compared with traditional sand filter media, crushed recycled glass can provide significant capital and annual cost savings.
Because particle counting is a more sensitive measurement than turbidity measurement, liquid-borne particle counting is playing an increasing role in potable water treatment. At San Francisco’s Harry Tracy Filter Plant, operators are using a water particle counter to fine-tune filter operations. Based on the successful performance of its online unit, plant management is planning to fine-tune filter runtimes even further by installing additional particle counters to monitor raw water influent as well as individual filter and combined filter effluent particle counts.
