A：Demineralized water equipment product description

Demineralized water,Desalted water generally refers to the finished water obtained by removing impurities in water such as suspended solids, colloids and inorganic cations and anions using various water treatment processes. Desalination does not mean that all salts in the water have been removed. Depending on the application, demineralization is allowed to contain trace impurities. The fewer impurities in the brine, the higher the water purity. Demineralized water contains little or no minerals. This can be done by distillation, reverse osmosis, ion exchange, or a combination of these methods.

Usually the Process have 3 process . It base on the feed water quality and output water quality

Process Flow ：

1.Source water tank →Pretreatment parts→ Single RO system→ RO tank→EDI system →DM water→10MΩ/cm outlet water.

2.Source water tank →Pretreatment parts→ Double RO system→Double RO tank→EDI system →DM water→15MΩ/cm outlet water.

3.Source water tank →Pretreatment parts→ Double RO system→Double RO tank→EDI system →Polish resin filter→ 18 MΩ/cm outlet water.

4.Source water tank →Pretreatment parts→ Cation resin →Anion resin →Middle tank→Mixed bed →DM water→15MΩ/cm outlet water.

B: Demineralized water equipment design basis

Raw water : tap water with TDS 1000 ppm

Out water: Resistivity≥15MΩ

Production capacity: 20000 litres/hr

Product water : for industry water

Voltage and frequency: 380V、415V、440V、50-60HZ

C:The demineralized water equipment control method  

Whole system use full automatically control model, both model can be exchanged accordingly. Sand filter with auto and manual back flush.The RO system automatic flushing at each start-up and shutdown. High water level auto stop, low water level auto start.Pump protected without water.Protected when no power, poor power, larger electrical current, leakage, short circuit.

D: Water demineralizer process flow

Source water tank →Feed water pump → Muti- media filter(sands filter) → Active carbon filter→ Cation exchange filter→ Anion exchange filter →Mixed Bed Demineralizer → Purified water

E: Why need to provide the source water quality report? 

1.The source water quality report can help engineers better understand the parameters of various indicators n the raw water, like the amount of all kinds of ions, bacteria, etc. Provide feasibility solution based on various parameter of raw water.

2. TDS(Total dissolved solid) and residual chlorine value is very import. before designing the proposal, engineers select high different pressure pumps with different pressures based on TDS value to make sure that the system can produce the clean water normally. Select the appropriate stainless steel material based on the residual chlorine to avoid the water leakage caused by corrosion.

3.From water analysis report can see the iron and manganese, turbidity, bacteria whether exceed the standard. Engineers can design the process flow chart and solution which best fit the demand to help reduce unnecessary expense which can help customers save the cost.

4. Engineers design the demineralized water equipment suitable proposal based on raw water quality report and product water purpose/standard which can operate normally and best fit the customer demand.

BTW: If source water is municipal tap water or clean reservoir water or spring water no need report.

But please inform us the water characteristic.
