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.
The newest addition to UV Superstore’s growing line of UV products is the Basic Series of residential UV units. The series offers simple and reliable units at an economical price. Two models are available, the BA-10 and the BA-15, with maximum flow rates of 10 and 15 gpm, respectively. These units are designed to mount either horizontally or vertically for maximum flexibility.
Filmtec RO 75- and 100-gpd home drinking water membranes help remove contaminants and reduce impurities. With a stabilized salt rejection rate of 99% at 75 gpd and 98% at 100 gpd, in standard sizes, the BW-60-1812-75 and TW30-1812-100HR home drinking water elements produce high-quality water quickly. The elements offer a balance of flow and high rejection, producing more water with 20% higher flow rates.
These residential UV systems can treat water at a variety of flow rates, from 7 to 20 gpm. Features include a stainless steel chamber, electronic ballast and an alarm to indicate lamp usage or power failure. The MWC-ES Series includes a solenoid valve to shut off the water supply in case of outages, and the MWC-EM Series has an additional UV meter to monitor wavelength.
The 3M Pro RO drinking water filtration system uses multistage filtration and includes a high-pressure booster that keeps consistent pressure. It is able to deliver 36 to 50 gal of clean water per day. The system has an electronic pressure switch set to activate at 40 psi and shut off at 60 psi. It is compact and can be installed centrally in a home. With its quick tank recovery, the system is convenient for sinks in kitchens, baths, wet bars and refrigerators.
Membrane processes can be classified in many ways, based on nature, structure or driving force. Hydrostatic pressure differences are used in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO) and gas separation as the driving force for mass transport through the membrane.
Growing range of applications spans the water treatment spectrum
If you attended the WQA Aquatech USA 2013 tradeshow in Indianapolis in April, you heard about many exciting topics, but probably none that have been in the works for as long as the septic study. After more than 10 years in the making, the Water Quality Research Foundation published results from the Environmental Impact Study that was funded to investigate the effects residential ion exchange water softeners may have on the performance of onsite septic tanks.
Septic study results show systems working together efficiently
Recently, the Water Quality Assn. (WQA) released the results of a survey it commissioned on homeowners’ opinions on water quality and treatment. The respondents showed increasing awareness of water quality and willingness to pay for treatment systems — all promising news for dealers and distributors of residential water treatment.
MCA Smart Technology couples advanced tank technology with electronics to make complex solutions easy. It is incorporated into a wide variety of Water Quality Assn.- and NSF/ANSI 44-certified water softeners, producing high service flow rates with a trickle of water to drain. It also includes filtration solutions for problem waters. Backwash bed expansion is 25% greater than conventional systems, saving gallons of water and keeping filtration media cleaner.
Pentair celebrates 80 years of its Everpure residential line of products
Pentair celebrated the 80-year anniversary of its Everpure line of products by showcasing its innovations in water treatment at the Kitchen and Bath Industry Show (KBIS) in New Orleans, April 19 to 21. Pentair is renewing its commitment to developing products that improve ease of use for consumers and reducing the products’ environmental footprint.
