Pleated filter cartridges are manufactured in polypropylene or cellulose media. The high-efficiency cartridges provide high surface filtration and comprehensive service life. Pleated media provide particulate removal and low pressure drops. Greater surface area ensures longer service life due to higher flow and particulate-holding capacity. All cartridges feature DOE Plastisol PVC end-caps for maximum sealing capability.
The company's pleated filters are a cost effective alternative to string-wound or polyspun filters. They are economical, multi-use products that are available in various micron ratings ranging from 1- to 50-micron nominal. There are several endcap configurations, and filter media available include polypropylene, polyester and cellulose. Open surface areas allow for high flow rates at reduced pressure drop, as well as high dirt-holding capacity, long service life, large throughputs and low operating costs.
WWIF South Africa and the Unlimited Child install Biosand filters in South African preschools
In a two- to three-day effort spearheaded by Ken Lister and Robin Tindall, with support from the local H2O Intl. Durban branch and Cape Town, South Africa-based H2O Intl. SA, several crèches (preschools for the underprivileged) in the KwaZulu Natal area received biosand filters, positively impacting the daily lives of several hundred children.
HaloPure removes 99.9% of viruses and bacteria while also preventing bacterial recontamination. Its uses are versatile and it can be applied to a variety of gravity and pressure POU devices. The media has been proven to enhance systems to help them exceed drinking water standards. It can be used with pitcher applications, inline, or with standard 10-in. cartridges for countertop and undersink systems.
The MWF refrigerator filter is NSF-certified and removes cysts plus a range of contaminants, including lead and mercury. In addition, it has been tested by a third party to remove more than 94% of five trace pharmaceuticals: ibuprofen, atenolol, fluoxetine, progesterone and trimethoprim. The filter is available for use in GE side-by-side and French door refrigerators.
There is a buzz of excitement throughout the industry surrounding the Water Quality Assn.’s (WQA) Sustainability Standards. The development of these standards was sparked by the WQA board of governors, which tasked the association with finding a proactive way to promote sustainability and environmental awareness across the entire drinking water treatment sector. This torch was eagerly taken up by industry volunteers, with task force ranks eventually growing to represent more than 50 WQA members and stakeholders.

Project provides assistance for utilities looking to boost understanding of biological filtration
The Water Research Foundation (WRF) is helping water utilities improve their understanding of monitoring and controlling biological filtration (BF) through a recently completed research project that resulted in a guidance manual that describes and evaluates current BF monitoring and control techniques.
The company’s coconut-shell catalytic carbon filters contain a granular catalytic carbon or carbon block capable of reducing many contaminants ordinary carbon cannot touch, such as chloramines, hydrogen sulfide, herbacides, pesticides, bad odor, THMs and other organics. They are available in 10- and 20-in. lengths, as well as 2.5- and 4.5-in. optical densities, making them compatible with most standard filter housings for point-of-use and point-of-entry applications.
Léger Foundation and Global Medic hold bucket-drilling day to provide 1,000 water filters
Following the damage caused by Typhoon Haiyan, thousands of Filipino families are still homeless today, with no access to clean drinking water. "Our team of volunteers on the ground has already distributed water to over 10,000 people, but it's still far from being enough!
