Small reverse osmosis desalination plant RO

Configuration list:

Reverse Osmosis is an effective and proven technology to produce water that is suitable for many industrial applications that require demineralized or deionized water. Further post treatment after the RO system such as mixed bed deionization can increase the quality of the RO permeate and make it suitable for the most demanding applications.

Proper pretreatment and monitoring of an RO system is crucial to preventing costly repairs and unscheduled maintenance. With the correct system design, maintenance program, and experienced service support, your RO system should provide many years of high purity water.

Feature: 

• Operation pressure: 0.2 ~ 0.3 Mpa, desalination rate: 95 ~ 99%


• Highly automation, stable operation, low fault rate and low operating cost


• Water for liquor blending water, canned products processing, bottle, bottled drinking water, drinks water


• Apply to electronic, chemical, electric power, pharmaceutical and other industries of water preparation

It uses quartz sand as filter medium, effectively intercept to remove the suspended solids in the water, organic matter, colloid particles, microorganism, chlorine, smelling and some heavy metal ions, etc., finally to reduce water turbidity, purify water quality.

GAC(granular actitavted carbon) is used for both removing organic constituents and residual disinfectants (such as chlorine and chloramines) from water. We make GAC media always by coco nut shell which is the best quality media.

Activated carbon filter can effectively remove color, odor, residual chlorine, organic matter and heavy metals, synthetic detergent, such as bacteria, viruses and radioactive pollution.

A water softener can be used to help prevent scaling in an RO system by exchanging scale forming ions with non scale forming ions. As with a MMF unit, it is important to have a 5 micron cartridge filter placed directly after the water softener in the event that the under drains of the softener fail.

Water softener is used to remove calcium and magnesium, and some other metal cations in the hard water.

Reverse Osmosis(RO) is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane. 

Reverse Osmosis(RO) 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. 

As the feed water enters the RO membrane under pressure (enough pressure to overcome osmotic pressure) the water molecules pass through the semi-permeable membrane and the salts and other contaminants are not allowed to pass and are discharged through the reject stream (also known as the concentrate or brine stream), which goes to drain or can be fed back into the feed water supply in some circumstances to be recycled through the RO system to save water. Reverse osmosis membrane should not allow chemical ion and bacteria, fungi, viruses through the pores, allowing only water molecules and solvent of volume less than 0.0001 microns passing.

Think of a pass as a stand alone RO system. With this in mind, the difference between a single pass RO system and a double pass RO system is that with a double pass RO, the permeate from the first pass becomes the feed water to the second pass (or second RO) which ends up producing a much higher quality permeate because it has essentially gone through two RO systems.
