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.
The UGACR chloramine reduction cartridge is a cost-effective POU option for reducing chloramines in municipal water supplies. The cartridge uses catalytic coconut shell carbon that acts as a chloramine “grabber.” It is available in 10- and 20-in. lengths, as well as 2.5- and 4.5-in. ODs, making it compatible with most standard filter housings.
In my previous article, “Ultrafiltration: A Business Growth Opportunity” (September 2013), I referenced a 2010 BBC research report stating that “the U.S. market for ultrafiltration (UF) technologies was worth $940 million in 2010. It is estimated to be valued at $1.24 billion by 2015.”1 Simply put, the business opportunities for UF are growing rapidly, which could prove extremely profitable for the savvy professional water dealer.
Exploring non-traditional uses for UF technology
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
