Filtering water in the washing machine reduces water consumption by 30%
Through a joint development with Dow Water & Process Solutions (DW&PS), Haier Group has commercialized the first Casarte eco-friendly washing machine using Dow ultrafiltration (UF) technology. The washing machine is designed and built with the new Dow Purinze UF module, which facilitates more than 30% reduction in water consumption while improving water quality by removing as much as 99 percent of common bacteria.
The Neo-Pure TL3 is an under-sink drinking water system that utilizes the latest UF technology to deliver great-tasting water and greatly reduce viruses, cysts and bacteria. This high-quality water is generated through two 0.5-µ carbon blocks and a hollow-fiber UF membrane. The system has a flow rate of 1 gpm, produces no wastewater, does not require a holding tank, and keeps all the essential minerals in drinking water necessary for great-tasting coffee and teas.
As a product manager of point-of-entry systems, I have often been asked, “How does one sell ultrafiltration (UF)?” This question is born out of two issues: First, dealers may view UF systems as niche technologies that do not offer the robust sales opportunities that more general products can offer; and second, in the eyes of the consumer, there are other systems that can do the same thing for far less money. Right or wrong, these views make the recommendation and selection of a UF system less likely.
Five steps for successful UF system sales
ZeeWeed 1000 and 1500 pressurized and submerged UF membranes are designed for pretreatment of feedwater for seawater RO (SWRO) systems. The immersed design also aligns well with dissolved air flotation technology and directly couples to SWRO. The membranes offer a reduction in operating costs and a reduced footprint while improving performance through energy savings and increased SWRO membrane life.
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
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
Chem-Aqua to distribute Nephros's ultrafilters in North America
Nephros Inc. and Chem-Aqua Inc., a wholly owned water treatment subsidiary of NCH Corp., announced that they have signed a non-exclusive distributor agreement for Chem-Aqua to distribute Nephros' ultrafilters (UF) in North America. Chem-Aqua is now beginning launch efforts, including scheduling training sessions and promoting UF to the hospital market.
Ultrafiltration (UF) offers an efficient and effective opportunity for treatment of extremely small contaminants. Recent developments in the chemistry and assembly of UF membranes make this technology available for a wide range of applications, from residential to commercial to industrial.
UF membranes provide efficient method for water treatment
This point-of-use, five-stage ultrafiltration (UF) system for residential applications produces cold filtered water with less water waste and lower operational costs compared to typical reverse osmosis systems. The UF system eliminates viruses, bacteria, benzene, chlorine, Cryptosporidium, pesticides and rust. It also reduces algae, chloride, copper, lead and mercury, and leaves healthy minerals in the water.
