Performance tested by the U.S. EPA, the Multi-Barrier System provides > 4-log reduction of Cryptosporidium and viruses, meeting disinfection requirements for the Ground Water Rule, Groundwater Under the Direct Influence of surface water and Long Term 2 Enhanced Surface Water Treatment Rule. It includes three treatment stages: sediment filtration, charged membrane filter and UV. It offers flow rates from 8 to 480 gpm, with capabilities for monitoring flow, filter life and UV status to provide fail-safe disinfection protection.
Over the past five years, the topic of rainwater harvesting has become prevalent everywhere we look. Many articles on this subject begin with an introduction about rainwater harvesting not being a new concept because systems have been around since before the ancient Greeks. They then cover the basics, from where water can be captured to its various applications. Storage tanks, pumps and filters are typically mentioned, but sometimes without specific details. This is for good reason: Rainwater harvesting systems, especially commercial-sized ones, can be complex.
Considerations for commercial rainwater harvesting applications
Ultrafiltration products available through Enpress One — Water Filtration Simplified product offering
Enpress LLC announced the formation of an exclusive strategic partnership and immediate availability for sales and distribution of Seccua ultrafiltration (UF) products through the Enpress One — Water Filtration Simplified product offering. This strategic alignment will bring inside-out UF products to the forefront of the marketplace for point-of-entry (POE) and point-of-use (POU) applications and markets.
Survey finds consumers do not consider specific contaminants when treating tap water
According to NSF Intl.’s 2013 Water Quality Survey, U.S. consumers are not doing their due diligence before buying a water treatment system. The survey of 942 American adults who use water filtration products found that less than one-fifth (17%) research the contaminants in their local water supply and purchase a water filter that has been tested and certified to reduce those contaminants.
Excito under-counter systems remove mechanical impurities, organic contaminants, and some bacteria and viruses. They reduce hardness, the concentration of heavy metals and up to 99% of chlorine, and improve taste and odor. Big Blue 10- and 20-in. housings can be mounted individually or connected in series. They consist of the housing and filter head with a 1-in. brass insert and are equipped with a valve that allows the release of pressurized air accumulated in the filter.
The town of Newport Center, Vt., is a small community of approximately 1,500 residents located just south of the U.S.-Canada border. A combination of drought and increased water use required the drilling of a new well for the community to supplement the two wells already in service. Water quality testing of the new well found arsenic levels at 20 ppb, well above the drinking water standard set by the U.S. Environmental Protection Agency (EPA) and the state of Vermont of 10 ppb.

In June 2012, a group of George Mason University (GMU) students and faculty traveled to the Amazon jungle to help an indigenous group of roughly 400 people called the Maijuna complete a water, sanitation and hygiene (WaSH) project. The project included teaching proper toothbrushing, hygiene and handwashing, and building bio-slowsand filters (biosand filters) for each household.

The Evo Eau reusable water bottle filters up to 99% of contaminants from tap water
Evo Eau — a reusable water bottle that filters up to 99% of contaminants from municipally supplied tap water — is now available through IndieGoGo.
Manufactured in the U.S. for more than 20 years, these filters provide increased surface area, low pressure drop and long service life. Pleated filters are manufactured in polypropylene for wider chemical compatibility and industrial use, polyester for water applications and reusability, and cellulose media for economical uses. Pleated filters are available in all standard sizes. Custom dimensions are welcome.
