Reverse Osmosis System

Reverse Osmosis(RO) is a process that uses semi-permeable spiral wound membranes to
separate and remove dissolved solids, organic,pyrogens,submicron colloidal matter,color,nitrate and bacteria from water.
Feed water is delivered under pressure through the semi-permeable membrane,where water permeates the minute pores of the
membrane and is delivered as purified water called permeate water.Impurities in the water are concentrated in the reject
stream and flushed to the drain is called concentrate water.

What should we know before buying industrial water purification system?

1. Pure Water Production Capacity (L/Hour,L/day, GPD).

2. Feed Water TDS and Raw Water Analysis Report (prevent fouling and scalling problem)

3. Available electrical power voltage and phase.(380V/50HZ,220V/50HZ etc)

4. Layout of place for industrial RO reverse osmosis system.

Reverse osmosis filter parts effect：
1. Booster water pump– provide the pressure to quartz sand filter/active carbon filter
2. Quartz sand filter– get rid of turbidity, suspended matter, organic matter, colloid, ect.
3. Activated Carbon filter–Remove the color, free chloride, organic matter, harmful matter, ect.
4. Water Softener–exchange “ions” of calcium and magnesium with the most common and easiest method.
5. Precision filter–prevent large particles, bacteria, viruses into RO membrane, accuracy is 5u
6. High pressure pump– Provide the high pressure to RO membrane
7. RO reverse osmosis– main part of the plant. The RO membrane’s desalting rate can reach 99%, removing over 99% ions
8. UV sterilizer or ozone generator— kill bacteria

Quartz Sand Filter 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. Activated Carbon Filter 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.
Water softener 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 Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions,
molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure,
a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial
processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and
the pure solvent is allowed to pass to the other side.

To be “selective”, this membrane should not allow large molecules or ions through the pores (holes),
but should allow smaller components of the solution (such as solvent molecules) to pass freely.
