West of Scotland Water (WoSW) awarded a contract, under competitive tender, for its first ultrafiltration plant to PCI-Water. This is the first installation in the United Kingdom using a hydranautics-based UltraBar system.
Small Groundwater Site Requires Metals Removal System
Microfiltration, Nanofiltration Help Meet EPA Standards at Lake
Hydrogen sulfide is a common component in wastewater treatment plant off-gases (e.g., biogas) and waste gases from certain industrial processes. It is highly toxic and odorous. Therefore, its release into the atmosphere is regulated. In addition, it is very corrosive, which can result in costly damage to equipment and piping systems used in biogas handling. Several technologies exist for removing H2S from gas streams, but many suffer from drawbacks such as insufficient removals, complexity or high cost.
Groundwater sources that can be used for drinking water purposes are requiring increasing degrees of treatment to meet the requirements of both the regulating agencies and the consumer.
UV is an accepted and rapidly growing technology for treating wastewater in the United States. In Europe, it commonly is used as a primary disinfectant in municipal drinking water systems. Other applications include food and beverage, pharmaceutical, semiconductor and power generation. This article will discuss three other commercially successful and growing applications.
Successful Ultraviolet for Commercial Applications
The topic of arsenic has received a lot of press coverage this year, ever since the Bush administration halted the EPA’s newly issued maximum contaminant level (MCL) of 10 parts per billion (ppb). Since then, the MCL was reinstated back to 50 ppb and further discussions and studies have continued. This article will discuss some of these updates.
How to Select from Available Treatment Options
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.
