In any membrane filtration system, scaling is inevitable. There are many forms of scale, some of the most common being calcium carbonate, calcium sulfate, barium sulfate and strontium sulfate. Left unmanaged, crystal scale will accumulate and become a mass of crystals on the surface of the membrane, causing blockage. This is harmful to reverse osmosis (RO) systems because it increases operating pressure. High pressure can put stress on the system and reduce product output and efficiency levels. A severely scaled membrane easily can reduce its gallon output by more than half.
Scale not only clogs pipes and destroys valves, it also consumes energy. According to the U.S. Energy Information Administration’s Annual Energy Outlook 2012, more than 10% of the energy consumed in a home goes toward heating water.
Many consumers use energy-efficient products to save money. What many do not know is that energy-saving efforts can be negated if they have hard water and do not address scale.
Developing a consistent standard for energy-saving anti-scale devices
The Greenfield Village mixed-use community, located at the southern end of the Salinas Valley in Greenfield, Calif., experienced significant problems caused by limescale buildup inside its 128 apartments’ water heaters and recirculation pumps. In the four years since the apartment complex was built, limescale buildup was so aggressive that many of the water heaters and recirculation pumps failed. The complex’s owners faced a minimum cost of $600,000 to replace the equipment.

Conditioning system helps apartment complex increase energy efficiency
Going green is all the rage these days. Whether it is constructing a wind farm, installing solar energy panels on a roof or simply switching to CFL light bulbs in a home, Americans are finding ways to tap renewable resources and conserve energy.
The push for energy conservation is good news for the water quality industry: The Water Quality Research Foundation Energy Savings Study showed that using softened water in a home improves energy efficiency and can save homeowners money on heating costs.
Water softener resin is extremely porous, which is beneficial because it allows for more surface area to capture calcium and other metals in source water. Surprisingly, 99% of ion exchange actually happens in the interior of the bead. Resin beads, ranging in size from 16 to 50 mesh, are abused daily during the backwash process and by contaminants in the source water. Resin could last much longer in these hostile environments with a few fairly inexpensive solutions.
Cleaning options to reduce resin fouling
ClearTAC uses template-assisted crystallization to reduce the formation of hard water deposits. It can be used where conventional water softeners are banned. No chemicals or salts are needed, and there is no brine discharge. The system uses long-lasting media and is virtually maintenance free. Carbon reduces or eliminates chlorine taste and odor, while beneficial minerals remain in the water. The system passes the W-512 standard for physical water treatment devices, and two independent lab tests confirmed results of 90% or more effectiveness in reduction of scale buildup.
This softener allows consumers to easily monitor and adjust water softness. It features the Custom Select blending valve, which adjusts water softness by turning a knob. SmartSoft technology “learns” water use patterns, ensuring soft water is available when needed, and the Salt Saver reduces salt use by up to 34%. The design includes an indicator that notifies users when salt is needed and a downward-angled salt refill opening for easier lifting and pouring of bagged salt.

750,000 families will receive water filters and high-efficiency cook stoves
Approximately 750,000 rural households in Rwanda’s Western province will receive water filters and high-efficiency cook stoves for home use. DelAgua Health is running the project in partnership with the Rwandan Ministry of Health and the Rwandan Environmental Management Authority. DelAgua is being assisted by Manna Energy Ltd., which pioneered carbon-financed water treatment.
She will assist customers in the application of ion exchange resins used in water treatment and more
ResinTech Inc. recently announced that Erin Uth, who previously worked in the ion exchange R&D laboratory at the company, accepted the position of technical support representative.
In her new role, Uth will assist customers in the application of ion exchange resins used in water treatment, including resin selection, performance predictions, process recommendations and system troubleshooting.
Uth graduated from Stony Brook University in 2011 with a B.S. in engineering chemistry.
