When considering reverse osmosis (RO) for water treatment, there are several things that should be taken into account. One of the most important things to consider is the quality of the water to be treated. RO is widely used to remove harmful inorganic contaminants; however, due to the limitations and higher operating cost, pretreatment of the water may be necessary. For example, hardness minerals are common in groundwater, and at high levels, pretreating with a softener is often recommended.
Environmental World Products focuses on component distribution, sourcing and new product development for commercial and industrial water treatment applications. Its product line includes RO system components, such as membrane housings, filter housings, bag housings, filter cartridges, couplings, control valves, flowmeters, solenoid valves, needle valves, controllers/monitors and pressure gauges.
The Complete RO Screen was developed with input from membrane manufacturers and treatment professionals. This package tests for most factors that can reduce the life of an RO membrane. Due to the nature of RO produced water, the testing was designed to provide lower detection levels. This test package is also beneficial for other applications that require pure water. New and improved compact packaging will reduce shipping costs.
SWI industrial-sized seawater RO systems have capacities ranging from 8,000 to 500,000 gpd. They feature duplex stainless steel multistage high-pressure pumps, FRP membrane housings, 8-in. TFC membranes, a non-corrosive prefilter and an advanced PLC-based control panel with touch screen, all mounted on a powder-coated steel frame that supports all instruments, piping and valves. Custom-made systems are available.
Today, beverage production facilities make a wide range of products, including carbonated soft drinks, energy drinks, juices, teas and purified drinking water. The number one ingredient in all of these products is water. Naturally, the quality of the water, as well as the operation of the water treatment system, are key to the quality and profitability of the facility.
Ultra-low-energy RO membranes help beverage facilities save energy and costs
Axeon CRO Reverse Osmosis Systems feature a sleek, ultra-compact design manufactured for residential applications and for feedwaters up to 1,000 total dissolved solids (TDS). The systems utilize a single-cartridge design, which allows for high-flow membrane performance. The large-diameter tubing of the CRO systems provides a 30% faster flow rate from the faucet. The unique flow path of these systems can reduce water waste by 50%, resulting in more water to the tank and less water down the drain.
Bruce Scholten hired to head Filtronics’ service department
Filtronics Inc. announced the addition of GE Water & Process Technologies reverse osmosis (RO) systems to its line of municipal and industrial water treatment solutions. According to Filtronics, the partnership will broaden its capabilities in the market for RO water treatment.
The Water Quality Assn.’s Guidelines for Disinfection and Sanitization of Water Treatment Equipment recommend that equipment be disinfected every six months, when it is serviced, after installation and when there is a contamination issue with the source water. If water treatment equipment is not properly sanitized, bacteria can grow and multiply on the inside surfaces of tanks and hoses.
Options for sanitizing RO and softener equipment
While consumers and business owners are now more cautious and conscientious with their dollars than at any time in recent history, there are still significant opportunities in both residential and commercial water treatment. These opportunities rely on three important facts:
RO system’s results outweigh initial problems
Uncle Sam and the U.S. Army recently called for an enlistment, but not in the traditional sense. This time, they needed to design and install a complete potable water treatment system for the U.S. Army Corps of Engineers at the Ft. Stewart army base in Savannah, Ga.
