Industrial Seawater RO Desalination Systems

Industrial RO Seawater Desalination Plant is used to remove salt and purify water. This system consists of booster pump, FRP/Carbon Steel pretreatment tanks (sand filter, activated carbon filter), cartridge filter housing, chemical dosing systems, high pressure pump, FRP membrane pressure vessel, 4040 or 8040 membranes, control panel and touch screen control.

Material and parts brand can be changes as regards to raw water quality and customer demand.
From touch screen panel, you can see all system flow diagram and automatic or manual control the system.
Membranes do not allow small particles, virus, bacteria to pass as a result your water becomes very clean and safe.

Pretreatment is used to remove large number of suspended solids, iron, turbidity, unwanted color, unpleasant taste, chlorine, sediment, organic contaminants, odors. In pretreatment we can control the follow manual or automatic for Reverse Osmosis Seawater Purification Plant.

After pretreatment water goes to cartridge filter housing, we call it as security filter, most of application we are using FRP or PVC Plastic material for cartridge filter housing or Bag Filter Housing. There is 1µm or 5 µm PP filter in cartridge filter housing for Reverse Osmosis Seawater Purification System.

After cartridge filter housing, water goes to membrane pressure vessel with High Pressure Pump, you have brand option for High Pressure Pump (Grundfos, Danfoss, CNP or Chunke) and it allows you to adjust your budget. Membrane housing shell inside depends on capacity we have 4040 or 8040 Membranes. Most of our project we are using DOW Filmtec, Toray , Vontron, Hydranautics, LG brand SW RO Membranes.

Membranes, in industrial Brackish Water Desalination Plant, are most important part. They block if parts size bigger than 0.001µm and molecular weight up to 150-250Dalton. It consists of impurities, particles, sugars, proteins, bacteria, dyes, organic and inorganic solids.

Also RO Seawater Desalination Plant can have chemical dosing at pretreatment or post treatment, like antiscaling (antiscalant) , antifouling,  pH adjustment, Sterilization & Disinfection chemicals.

Before Buying Industrial Water Purification System, you should know:

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

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

3. Iron and Manganese must be removed before raw water enter reverse osmosis water filtration membrane

4. TSS (Total Suspended Solid) must remove before industrial water purification system’s membrane.

5. SDI (Silt Density Index) must be less than 3

6. Must be sure your water source does not have oil and grease

7. Chlorine must be removed before industrial water treatment system

8. Available electrical power voltage and phase

9. Layout of place for industrial RO reverse osmosis system
