WINTERIZING A REVERSE OSMOSIS SYSTEM

WINTERIZING A REVERSE OSMOSIS SYSTEM

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 […]

REVERSE OSMOSIS VS. ION EXCHANGE

REVERSE OSMOSIS VS. ION EXCHANGE

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 […]

PFOS

PFOS

What are PFOS and PFOA? PFOS and PFOA stand for perfluorooctane sulfonate and perfluorooctanoic acid, respectively. Both are fluorinated organic chemicals, part of a larger family of compounds referred to as perfluoroalkyl substances (PFASs). These substances are synthetic compounds that are unique for being water and lipid-resistant. Because they deter water, grease and oil, fluorochemicals […]

Sulfur

Sulfur

Symptoms: Sulfur produces that distinct “rotten egg” odor and sulfate-reducing bacteria produce a slime and can promote the growth of other bacteria, such as iron bacteria. The slime can clog wells, plumbing, and irrigation systems. Bacterial slime may be white, grey, black, or reddish brown if associated with iron bacteria. Hydrogen sulfide gas in water […]

Chloramine

Chloramine

Symptoms: Bad taste, odor, skin irritation and eye irritation. Causes: Chloramine, or NH2Cl, is commonly used in low concentrations as a secondary disinfectant in municipal water distribution systems as an alternative to free chlorine chlorination. Chloramines are disinfectants used to treat drinking water. Chloramines are most commonly formed when ammonia is added to chlorine to […]
