drinking water purifier machine
Containerized Inverse osmosis water dispenser ro water filtration system with membrane filter home application






Reverse osmosis systems work by applying a high pressure pump to a concentrated solution of unfiltered water, which can be in the form of seawater, brackish, or tap water. The system forces the water through a semipermeable membrane, leaving virtually all of the dissolved salts and other substances behind. The type of water you’re looking to purify using reverse osmosis systems will determine which pump will be needed to use in order to see effective results. Seawater requires larger and higher pressure pumps compared to brackish or tap water since it has a higher content of total dissolved solids (TDS). Pretreatment is necessary when working with reverse osmosis systems to protect the membranes from fouling and failing prematurely. This degradation of the reverse osmosis membrane occurs due to a build up of foulants such as silica, iron, manganese, calcium carbonate, dead and living organisms, and magnesium carbonate.
Working principle
Reverse Osmosis works by using a high pressure pump to increase the pressure on the salt side of the RO and force the water across the semi-permeable RO membrane, leaving almost all (around 95% to 99%) of dissolved salts behind in the reject stream.
Advantages
The desalination of brackish water is actually the desalination of salt water, so that the salt water is desalinated or desalinated or reaches the drinking water standard after treatment.
Can be personalized according to the actual needs of users, using more advanced back pressure technology, can save users a lot of operating costs and equipment technical costs.
