Stages of Commercial RO Plant

Stages of Commercial RO Plant

The Commercial RO Plant, which is among our most popular, often comes in conventional models. These systems can be modified to include UV sterilizers, water softeners, anti-scalant dosing systems, multimedia filters and activated carbon filters for pre and post-treatment.

Commercial RO Plant features

Commercial RO Plants remove salts and other contaminants. It also has the ability to reject microorganisms. These RO plants’ primary characteristics include:

1: Powder coated frame.  

2: Pre-filter for sediment removal.

3: Stainless steel casing.

4: Pump for high pressure.

5: Product and Reject Flow Meters in FRP Pressure Vessels.

6: Switch for low and high pressure.

7: TFC membranes with high rejection.

Stages of Commercial RO Plants

  • Dosing system for chlorine and hypochlorite

Before filtering, raw water is treated with a chlorine/hypo chlorite dosing system to disinfect and oxidize iron and manganese (if present). In the presence of water, sodium hypochlorite reacts to produce hypochlorite acids, which is a disinfectant.

  • MGF (Multi Grain Filter)

It used to filter out waterborne suspended particles. Three layers of media, including sand, garnet, and anthracite coal, make up this structure. At the bottom, there is a layer of gravel. The top has less dense material, whereas the bottom has denser media. Smaller contaminated particles are contained at the bottom and larger contaminated particles at the top. It can get rid of particles that are 15 to 20 microns in size.

  • Sand pressure filter

Before feeding the Commercial RO Plant, raw water is first filtered by filtration units connected in series. Suspended matter and turbidity from raw water are removed using a pressure sand filter.

  • Activated Carbon Filter (ACF)

It is used to remove organic matter, chlorine and chloramines from water. Coal, nutshells, and wood are the main components of ACF. For the removal of pollutants, it typically uses an adsorption technique. By transferring electrons from the carbon filter to the chlorine and chloramine residue left on the carbon filter, these are eliminated.

  • SMBS Dosing system

The membrane may become oxidized by the chlorinated water, thus we provide a sodium metabisulphite dosing system to prevent this.

  • Antiscalants Dosing system

To stop scale forming on the RO membrane, chemicals are added to the water. Antiscalants prevent scale formation by getting absorbed to the scale and forms salt crystal thus preventing attraction between saturated contaminants and crystal surface.

  • Micron Cartridge Filters

20 micron, 10 micron, 5 micron, 1 micron, 0.45 micron and 0.2 micron cartridges are included in a series of micron cartridge filters. After a certain number of days of use, this cartridge needs to be replaced.

  • Pump for high pressure

Water feed pressure must be increased for the reverse osmosis process to work. A vertical multistage centrifugal high pressure pump with a stainless steel construction is offered for this purpose. R.O. operating pressure for the system must be between 14 and 16 kg/cm2. For safer system operation, tools including a High Pressure Switch, Pressure Gauge and recirculation valves are supplied.

  • Reverse Osmosis membrane

Spiral wound TFC-polyamide membranes are the most often utilized type of RO membrane. Feed spacers, permeate tubes, permeate spacers and membranes make up its essential parts.

Water from the input is split into two streams in the Commercial RO Plant: product water and reject water. Product water is processed water containing reduced TDS. Reject water is the concentrated water. Filtered water is first fed into a pressure vessel under high pressure and then it is collected in the centre core tube. Each membrane’s treated water is collected in a single product water storage tank and the refuse is discharged or reused.
