Pure Drinking / Drinkable 3000lph Reverse Osmosis Water Treatment Machine

Technical descriptions:

The water treatment system is divided into 4 parts: Pre-treatment, RO unit, sterilization parts and matching parts. RO is the core of the system.

Pre-treatment: Raw water pump, Quartz sand filter, Active carbon filter, Sodium ion exchanger, Cartridge filter, etc. Functions as below:

a, Avoid incrustation generating on membranes surface; ( Includes Fe3,Fe2,CaCO3,CaCO4,SrSO4,CaF2,SiO2,Fe and Aluminum-oxide) ;

b, Avoid colloidal substance and fluidized bed block up;

c, Avoid organism block up;

d, Avoid microorganism block up;

e, Avoid breakage to membranes from oxidizing substance;

f, Make sure stable water production by RO;

g, Make sure no block up from high hardness;

1.1,Raw water pump:

Provide necessary flow and pressure for equipment afterwards; (NANFANG brand,NO 1 quality pump in China )

Parameters:

Model: CHL8-30

Material: SUS304

Flow: 8m3/h

Lift: 25.5m

Power: 1.1KW

Revolution: 2900Rpm

1.2, Quartz sand filter:

Apply high quality SUS304, with automatic control system, piping system, includes manhole, hand hole, water distribution device on top and bottom, filter material, it is pressure model.

Inside the sand filter, there are put several layers of different diameter quartz sand. Filter design should make full consideration of back flush intensity, unstable system operation are mainly caused by sand filter back flush design defect, Poor back flush effect will increase top sand clotting SDI (pollution index), and will cause pollution to the membranes.

Considering once restart after back flush, the new filter surface is not full generated, impurity is easy to get through, our sand filter apply low flow rate operation model, this will enhance filter effect and reduce pollution afterwards.

Back flush will make 15-25% expansion to the filter materials, it is better to use compressed air to work together, strength 18-25L/sm2. Impurity will be below 1 under this situation.

Parameters:

Model: SUS-600

Operation model: Pressure model automatic operation, manual model flush and back flush

Flow rate: 6m3/h

Design pressure: 0.3Mpa

Diameter: Ø600mm

Height: 2500mm

Thickness: 2mm on body and 3mm on top

Material: SUS304

Filter material: Fine quartz sand

1.3, Active carbon filter

Apply high quality SUS304, with automatic control system, piping system, includes manhole, hand hole, water distribution device on top and bottom, filter material, it is pressure model.

Main function is to remove organic substance and residual chlorine. Inside is filled with water cleaning active carbon, the water after passing this filter: 1, 60% organic substance will be absorbed; 2, residual chlorine will be absorbed, the action is not only absorption, while it will generate catalysis on active carbon surface, so the active carbon will not be full absorbed, just lose little carbon.

After passing sand filter and active carbon filter, the water will meet standard to enter purifying device: SD1≤4；

Parameters:

Model: SUS-600

Operation model: Pressure model automatic operation, manual model flush and back flush

Flow rate: 6m3/h

Design pressure: 0.3Mpa

Diameter: Ø600mm

Height: 2500mm

Thickness: 2mm on body and 3mm on top

Material: SUS304

Filter material: Fine active carbon

1.4, Cartridge filter

To avoid quartz entry into RO to break membranes, the membranes can be used for 3 months under normal working situation, the design is suitable for quick cartridge change.

Parameters:

Model: SUS-320

Operation model: external pressure model

Flow rate: 6m3/h

Design pressure: 0.3Mpa

Diameter: Ø320mm

Height: 1600mm

Thickness: 1.5mm

Material: SUS304

Cartridge material: Spray-fusing polypropylene 5um

Cartridge qty: 6pcs

1.5, RO unit

RO membrane is the key part of whole RO, it will decide the system workable or not. The water passing RO can remove bacterial, organic substance and microorganism.

No phase change will be generated in RO device during water purification. Water recovery rate is high, small in dimension, high automation.

Whole SUS304 rack, automation part apply AC contactor control, apply flow meter, pressure gauge and auto flush electrical magnetic valve, etc.

Protect device:Low pressure and high pressure protect switch is set before water entry and after water discharge. Booster pump and system will stop when water supply is not enough. Make cut off on booster pump when there is too much discharge pressure to avoid system running under pressure exceeding status.
