The point-of-use (POU) residential reverse osmosis (RO) system has remained a saturated, commoditized segment within the water filtration market with few technological advancements in system performance for nearly two decades. Yet, RO technology produces high-quality drinking water for consumers, making it essential to the success of water treatment businesses.
New membrane technology designs waste less water
Point-of-use reverse osmosis element design, specifically the distribution of feed water to the membrane, has remained somewhat static since the introduction of thin layer/film composite (TLC) or non-cellulose membranes. Most reverse osmosis systems, depending on design and operating conditions, dispense 70 to 90% of feed water to the drain. Many RO systems use a similar membrane and distribute water through the element in the same manner, so there is little opportunity to increase the system’s efficiency.
Eric Seo will be responsible for product development for the company's membrane filtration technology
Water Planet, a global supplier of membrane-based water treatment solutions, announced that Eric Seo joined the company as product development engineer.
Seo will focus on product development for the company’s PolyCera membrane filtration technology, which offers ceramic-like performance with polymer economics.
Arizona correctional facility solves water quality problem with custom solution
The Red Rock Correctional Center complex was originally built in 2006 outside Eloy, Ariz., by the Corrections Corporation of America (CCA) to house inmates for the state of California. In 2013, CCA agreed to a contract with the state of Arizona to administer up to 1,500 prisoners at Red Rock, and relocated its California inmates to other CCA locations.
IntegraFlux UF modules feature XP fiber, which offers up to 35% higher permeability than previous-generation UF fiber. XP fiber provides higher flux, higher water recovery, lower waste, and reduced energy use, providing high productivity with a small footprint. The modules and IntegraPac skids with XP fiber are ideal for industrial and municipal applications.
The Watts R14 Series reverse osmosis (RO) systems are designed for water purification in commercial settings. Applications include municipal water treatment, steam boiler and steam sterilizer makeup, laboratory use, spot-free car washes, food processing and metal plating and finishing, as well as water for humidification.
Cold feed water temperatures can cause havoc for reverse osmosis system operators. As water temperatures decrease, so can permeate water production rates. Permeate flow decreases by approximately 3% for every degree Celsius decreased.
