There are many applications today that offer potential new business for water treatment dealers because of increasingly stringent drinking water requirements. These applications include the removal of arsenic, nitrate, perchlorate, fluoride, radium, uranium and other emerging contaminants. The removal of these contaminants may be required by local, state or federal regulations.
Simple technique provides safety and economic advantages for POU/POE systems
Safe landfill disposal of spent arsenic removal media
Ion exchange resin beds are often an attractive growth medium for biological organisms, such as bacteria, mold and algae. In some cases, these growths can build up in the resin bed and physically foul the resin. In most cases, however, the concern is that these organisms will contaminate the effluent water leaving the ion exchange system.
Effective methods for cleaning biologically fouled resin
There are many niche markets for the water treatment dealer to pursue. A multitude of industries rely on a consistent source of deionized water for manufacturing and production, and as a source of makeup water for power generation and process water.
Deionization provides quality water for painting method
Let's take a closer look at the technology and operation of ion exchange resins and processes used today in industrial water treatment systems.
Nitrates have no detectable color, taste or smell at the concentrations involved in drinking water supplies, and they do not cause discoloration of plumbing fixtures, so they remain undetectable to our senses. Nitrate removal processes must be either foolproof or include extensive monitoring of the treated water to detect breakthrough or determine the need for regeneration.
