Commercial Seawater Reverse Osmosis Desalination Systems

Commercial Seawater Reverse Osmosis Desalination Systems

Commercial Seawater RO membrane filtration water treatment 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, 2540 or 4040 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.

Seawater commercial water treatment systems Capacity range between 1.4m3/hour to 38m3/day. If you need bigger than this capacity please see our Industrial Seawater Desalination Systems.

All RO Seawater membrane filtration water treatment plants are started from booster pump, it feeds raw water to pretreatment tanks. Depends on capacity pretreatment tank size and numbers can be changed. Because of High TDS (total dissolve solid) and salt water’s corrosion, we are using FRP or Carbon Steel material for pretreatment tanks. Pretreatment consists of Sand Media Filter Tank, Activated Carbon Filter Media Tank and Softener Tank which has ion exchange resin inside, they are very important for commercial RO Desalination Machine.

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 seawater commercial water treatment system.

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 in Commercial Seawater Reverse Osmosis Desalination 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.

In Chunke when we check customer water analysis report, sometimes because of scaling and fouling problems, we can use CIP (Clean in Place) System, it washes membrane in membrane housing and make membrane life longer. So you can reduce your maintenance cost for commercial water treatment systems.

Electrical Power of Industrial RO Desalination Machine

For sweater commercial water treatment system needs 220-380V/50Hz/60Hz. For bigger capacity, because of high pressure pump, it needs 380V/415V 50/60Hz. As regards to your SWRO Desalination Machine design, we will check your electrical supply and decide fix power to you.

What is a desalination system?

Desalination system is a kind of membrane filtration water treatment. Some water source like seawater or some underground water or some river has high level salt inside. For high level salt water has over 10000ppm salt inside. Our commercial RO Seawater Desalination Plant remove this salt from raw water by RO (reverse osmosis) membrane system technology. This technology is called as membrane filtration water treatment process. Because SW RO type membranes salt recovery rate is over 99%. So, you can get accessible, usable or drinkable fresh water.

Especially, if you have boiler and need very pure water, our marine boiler water treatment systems, remove all salt from seawater and you can use your boiler in high efficiency. Marine boiler water treatment systems reduce your chemical and energy cost. Chunke experienced engineering team can design a lot of marine boiler water treatment systems.

Chunke membrane filtration water treatment systems can be used in wide range of water quality. Every water source needs different and special design. Seawater one of the most important water source in the world. To use seawater in our process or drink we have to convert it to fresh water. Our reverse osmosis seawater commercial water treatment systems help to you for this purpose. Nowadays, a lot of business is near to seawater source, their boiler needs special marine boiler water treatment machine. To get more information about our marine boiler water treatment system, please contact with us. Chunke gives good solution for membrane filtration water treatment.
