RO Plant or Reverse Osmosis Systems is working by using a high-pressure pump to increase the pressure on the salt side of the RO and force the water across the semipermeable RO membrane, leaving almost all of the dissolved salts left in the reject stream. This concludes the ro plant working principle.
We are an established manufacturer of reverse osmosis plants. And, To enhance the efficiency and life of the Reverse Osmosis plant, effective pretreatment of the feed water is required. Selection of the right pretreatment will maximize efficiency and membrane life by reducing:
Determining Pretreatment Requirement:
If the feed water has traces of heavy metals, it is highly recommended to dose some chlorine to change the dissolved heavy metals to physical form, the media filter will filter most of it in a ro water purifier plant.
Reverse Osmosis Plant Selection of Membrane:
Membrane elements are an important part of RO plants. The proteins (mostly polyamide) that makeup membrane elements vary depending on the ending clarity and intake water seawater or brackish water etc.

Weak Caustic lye, around 5-6 Be (40 - 50 gpl), is collected in a storage tank from the impregnation and washing chamber. The suspended particles, fluff, and other debris are then filtered in a filtration unit. The feed to CRP then runs through a series of preheaters, which use flash vapour from the condensate flashes to preheat the wash liquor, resulting in little steam loss while heating the wash liquor to its boiling point. The liquor in the tubes comes into touch with the steam in heater 1's shell side and begins to boil. The vapour liquor combination enters the flash vessel via a tangential entry, where the vapors separate and enter the 2nd stage shell.
The lower pressure developed with the help of a water ring vacuum pump causes the boiling in the successive effect. The boiling point of the liquor is reduced as a result of the decreasing pressure, and it begins to boil. Due to the pressure differential, the concentrated liquor enters the second heater and comes into indirect touch with the produced vapour, and the process is repeated. A product pump removes the concentrated product from the last step. This is then either stored or purified using a Concentrated Lye purification technique.

The vapour generated at the final stage of the caustic recovery system / caustic soda recovery plant must be condensed. Either hot water or an adiabatic evaporator system is used to accomplish this. Water at room temperature is passed through tubes of an exchanger in a hot water system, where it becomes hot due to vapour. Because this hot water is uncontaminated, it can be safely used in the process or boiler as needed.
The effluent is transported through the exchanger and sprayed in an Adiabatic Evaporator in some circumstances where the hot water created cannot be properly used. Waste heat is lost in the form of vapour, resulting in lower effective steam usage. Also gone is the annoyance of too much hot water.
RO recovery rate is influenced by the quality of the feed. The contaminants are generally inorganic salts and organics which
The fewer TDS you have, the less applied pressure is required in order to push the water through the pores of the RO membranes. That is the reason BWRO can achieve up to 70-97% recovery (especially with new system configurations) and SWRO is limited to 35-45%.
All Reverse Osmosis plants are basically Desalination Plants but desalination is being referred to sea water normally. As sea water has very high TDS requires very high pressure to force sea water through membranes which are different then brackish water membranes.
As sea water desalination plants by multi effect evaporator manufacturer requires very high pressure pumps in short energy consumption is very high in sea water reverse osmosis systems forced to research for alternative of reverse osmosis plants for seawater desalination found Multiple Effect Distillation very cost effective in terms of energy consumption but fixed capital investment is bit higher. In many cases Multiple Effect Distillation(MED) would be associated with Thermal Vapour Compression ( MED TVC), or Mechanical Vapour Compression (MED MVC).
