& Nantong tons of seawater reverse osmosis desalination device Seawater desalination, also known as seawater desalination, is the process of removing salt from seawater to obtain fresh water. The reverse osmosis method uses the principle of osmosis to compress seawater to a certain osmotic pressure, reverse osmosis of the water in seawater through a semi-permeable membrane, and produce fresh water.
The reverse osmosis process is based on a semi-reverse osmosis membrane, which passes water at very high pressure while blocking dissolved solids such as minerals, salts or organic compounds. A reverse osmosis membrane consists of a thin polymer sheet bonded to a porous base and spirally coiled around a plastic pipe. Unlike microfiltration membranes and ultrafiltration membranes, reverse osmosis membranes do not have a specified pore size. However, these pores are enough to block the passage of even the smallest bacteria and viruses.
Reverse osmosis is the reverse effect of the natural flow of osmosis. In water purification systems, pure water is extracted from salt water and contaminated water. By applying pressure to the contaminated side, the semipermeable membrane screens out impurities and allows water molecules to pass through.
A complete set of seawater reverse osmosis desalination equipment is generally used to remove suspended solids in the incoming water and protect the reverse osmosis membrane. It must be equipped with a pretreatment device before passing through the membrane, usually using a multi-stage filter (media filter, bag filter, core filter, etc.).
Raw seawater is fed from the inlet, through a pressurized pump, to a multi-stage filter. The filtered seawater enters the reverse osmosis membrane through a reverse osmosis high-pressure pump, where the seawater is decomposed into fresh water (product water) and wastewater. (concentrated water), fresh water enters the disinfection cabinet to the fresh water cabinet, and waste water is discharged.
The amount of net water separated by the system is called recovery rate (or conversion amount). Usually expressed as a percentage. The recovery rate of normal seawater is %~%. In many cases, in order to improve the recovery rate, a reverse osmosis device will be designed as two or more stages. The recovery rate can exceed %, but the investment in membranes will increase.
The amount of water passing through the reverse osmosis membrane is directly proportional to the pressure applied. This pressure is called the driving pressure, which is equal to the supply pressure (system pressure) minus the finished product back pressure (the pressure at the diaphragm outlet). If the driving pressure increases, the flow of fresh water increases. In addition to pressure, the temperature of the inlet water also has a relatively high impact on freshwater recovery. The recovery rate is usually low in winter and high in summer.
