Product Description

21CBD Commercial Reverse Osmosis Water Purification Systems is used to purify water

Chunke Reverse Osmosis water treatment system can be customized as regards to application. Some industry need very high grade purity for permeate water.
Our solution for high grade purity double pass ro system and if it is necessary electrodeionization water treatment system.
Double Pass RO system has pretreatment section, raw water first enter the pretreatment than goes to ro membrane, at first pass we get pure water called as permeate and concentrated water. To reduce TDS more, we send first pass permeate to second ro membrane and water becomes more pure.

Industrial Water Purification System Capacity range between 38m³/day to 7500m³/day. If you need smaller than this capacity please see our commercial water treatment systems.

 

All industrial reverse osmosis water treatment systems are started from booster pump, it feeds raw water to pretreatment tanks. Depends on capacity pretreatment tank size and numbers can be changed. Also depend on raw water source and TDS (Total Dissolved Solid) material can be changed. In Chunke if water source is Tap or low TDS fresh water, we can use FRP, Stainless Steel 304 or 316. If salt content and TDS high, because of the 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 reverse osmosis water filtration.

 

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 flow manual or automatic for industrial water purification.

Working principle: 

Reverse osmosis technology

With the report of raw water analysis and the different requirements in different field, we can make a appropriate design for you. 

1) Adopts RO membrane from VONTRON, which can remove 99.7% inorganic salt, heavy metal ion and completely get rid of colloid, microbiology organic materials, germ, protozoa, pathogens, bacteria, inorganic chemical and so on. 

2) No need to add any chemicals, stable pure water quality, and no pollution drained, low produce cost. 

3) Equipped with pretreatment system, such as active carbon absorption filter and refined quartz sand filter 

4) 304 stainless steel rack and pipe accessories connection. 

5) Equipped with auto pressure protection system and on -line monitor. 

6) Automatically and manually wash RO membrane. Also the design of washing the RO membrane is by chemical solution (citric acid or sodium hydroxide optional) 

7) The lifespan of the whole system is long, operation simple, the applicability is strong.

Function of each part of water treatment plant 

1.feed water pump -- provide the pressure to quartz sand filter/active carbon filter

2.Multi-medium filter-- get rid of turbidity, suspended matter, organic matter, colloid, ect.

3.Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter, ect. 
4.Softener--exchange "ions" of calcium and magnesium with the most common and easiest method.
5.Security filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um
6.High pressure pump-- Provide the high pressure to RO membrane 
7.RO system-- 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
