Membrane systems operating at 82% recovery will convert 82% of the total raw water input into treated permeate, with the remaining 18% being sent to waste as concentrate (or reject). The recovery rate is monitored using flow meters installed in the permeate and concentrate piping.
Water quality and purification processes have improved greatly over recent years alongside the demand for drinkable water which has also increased. Today’s membrane treatment plants can be tailored to fit specific needs and the membrane treatment methods used can reduce contaminants more than ever before. Where the desired outcome is stable, clean water with an appreciable return on the investment, upgrading to a membrane water treatment system is backed by cutting edge industry science.
During normal operation of an R/O water treatment system, the membrane elements will often suffer a reduction in performance due to the accumulation of small particles, colloids, microorganisms, or precipitated salts collecting on the membrane surface.
Membrane water treatment is a process that removes unwanted constituents from water. A membrane is a barrier that allows certain substances to pass through while blocking others. Water treatment facilities use various types of membranes and processes to clean surface water, groundwater, and wastewater to produce water for industry and for drinking.
Membranes are loaded from the feed end of the pressure vessel. To better understand the installation procedure, the following definitions are helpful:
There exists a potential for calcium, barium, strontium, fluoride and silica compounds to precipitate in the concentrate or brine channels of the reverse osmosis membranes. Precipitation occurs when the solubility limits of these various salts and silica is exceeded.
