Today, UV technology is used in virtually every part of the world and is considered the best available technology for treating waterborne microbiological contamination. UV treatment destroys the growth of microorganisms without the use of harmful chemicals, providing disinfected water without unwanted odors, taste, or changes in pH. Ultraviolet filtration is a method of disinfection […]

Reverse osmosis is the opposite process, except for the water to move in the opposite direction, pressure must be applied to the solution with the higher concentration in an excess of osmotic pressure. When pressure is applied to the feed water (concentrate solution), the flow of the liquid reverses, creating permeate water. This permeate water […]

The mineral tank is connected to a brine tank that is filled with salt, which periodically regenerates the resin beads. During the regeneration process, the salt solution in the brine tank flushes the calcium and magnesium off the resin in the softener and the resin is recharged with sodium, an exchange of positive and negative […]

Water filtration has been present throughout recorded human history. There are records of water filtration as far back as 2000 BC. Human bodies consist of 70% water and therefore need water — potable water — to sustain them. Historically, civilizations were constructed around bodies of water, but the water was not always ideal for human […]

Nanofiltration is a somewhat recent filtration method that depends upon membrane permeability. While there are some similarities between nanofiltration and reverse osmosis technology, the two technologies are distinct. If reverse osmosis can’t be used for a specific application, then a nanofiltration water system is the next best alternative in removing, among other things, some multivalent […]

Forming of Residual Chlorine To prevent membrane contamination of biofouling, chemical substances such as chlorine, sodium hypochlorite, calcium hypochlorite are usually used for disinfection. They rapidly hydrolyzed into hypochlorous in water. Cl2 + H2O ← → HOCl + HCl NaOCl + H2O ← → HOCl + NaOH Ca (OCl) 2+ 2H2O ← → 2HOCl + […]

WINTERIZING A REVERSE OSMOSIS SYSTEM: LONG-TERM RO SYSTEM SHUTDOWN AND PRESERVATION A reverse osmosis (RO) system or nanofiltration (NF) system, as part of a water treatment solution is typically exposed to varying operating conditions. However, changes in operating conditions may warrant the need for long term system shut down or relocation of the system. Such […]

PURE WATER PRODUCTION FOR INDUSTRIAL APPLICATIONS: REVERSE OSMOSIS VS. ION EXCHANGE: Electrocoat systems require clean water of certain criteria for the pretreatment final rinse, paint post rinse, and electrocoat tank. The ions introduced into these processes must be kept to a minimum, among other requirements. Normally, these criteria can be met by reverse osmosis or […]
