RO pure water machine 1000 LPH

Ⅰ、Brief introduction

RF-RO-1T/H integrated purified water producing unit is self-developed newly purified water treatment equipment, which based on introduction of international advanced technology and combination of domestic actual situation. The main component adopts the international most advanced imported reverse osmosis membrane as the main filter component. It is consist of stainless steel mechanical filter, stainless steel active carbon filter, stainless steel ion exchanger, stainless steel precision security filter, stainless steel multi–stage centrifugal pump, cycling back washing system, ion reclamation system, high and low voltage protection and control system, electric time-lag control system, conductivity current display system and reserve osmosis membrane filter system etc. The unit is made of the SUS304 sanitary stainless steel. It has functions such as fully automatic intelligent control, automatic cycling washing, high-low voltage protection and automatic continuous water discharge. It has advantages of rational and compact structure, small sized occupation and easy to operation, good performance, reliability and safety and etc.

The working principle of the reverse osmosis membrane is: enable solvent (water in general) to go through the reverse osmosis membrane to segregate, refine and concentrate. Reverse osmosis membrane can remove the impurities, colors and off-flavor, hazardous bacteria, virus, heavy metals, high modular organics, ion, fine particles and dissolved salt and etc. Desalting rate of single membrane is high than 99%. RO membrane filter has been widely used in water treatment of food, chemical, medicine, industry, sewage and etc.

A、 High voltage protection relay

Hydraulic protection device will avoid unnecessary damage when hydraulic pressure exceeds rated pressure. That is, system will stop running automatically once over pressure.

B、Stainless Steel Mechanical Filter

The mechanical filter is made of SUS 304 stainless steel. Quartz sand is used to filter the impurities of original water as filter media, which can purity the original water and is convenient for back washing.

C、Stainless Steel Active Carbon Filter

The active carbon is made of the SUS304 stainless steel. High quality active carbon is used to   absorb color and off-flavor of original water as filter media, which can purify the color and adjust taste of original water and is convenient for back washing.

D、Stainless Steel Ion Exchanger

The ion exchanger is made of the SUS304 stainless steel. High quality 732 resin ion is used to filter and decrease effectively calcium and magnesium ion, sodium chloride ion of original water as exchanging media, which can adjust PH value, soften and adjust taste of original water and is convenient for back washing and regeneration of ion.

E、Low Pressure Protection Switch

Fitted on the inlet of original water, low pressure protection switch is used to protect automatically multi-stage booster pump and avoid damage from idling of pump owing to water shortage by detecting if hydraulic pressure meet requirements.

F、Precision Protection Filter

The precision protection filter adopts high performance Polyvinyl acetate filter core and its hole diameter is only 0.2mu, which can filter residues remained in the water after pretreatment and prevent the residues flowing into RO membrane and blocking the membrane.

G、Multi-stage Centrifugal High Pressure Pump

Multi-stage Centrifugal High Pressure Pump is used to boost the hydraulic pressure in operation system of RO purified water machine, which ensure to meet working pressure of the RO membrane. For details, please refer to the instructions of high pressure pump.

H、Water feeding Solenoid Valve

The solenoid valve is fitted on the inlet of water. When RO machine is filled with water and stop running, solenoid valve will close automatically and cut off water feeding by high pressure pump to avoid water in RO machine reverse flowing.

I、Purified Water Flow meter

Purified water flow meter adopts panel-typed instant display meter, which is good looking and accurate in measuring. It is used to display output of RO purified water machine.

J、Sewage flow meter

Sewage flow meter adopts panel-typed instant display meter, which is good looking and accurate in measuring. It is used to display amount of discharge of RO purified water machine.

K、 RO Membrane housing Component and Membrane

RO membrane housing is made of SUS304 stainless steel and polished internally and externally. Using ABS food level plastic of head, it has characteristic of durable in use, good looking and sanitation. RO membrane adopts world’s most advanced   membrane imported from USA, which ensure purified water produced meet the standard.

L、 Water Quality Conductivity Meter

Equipped with two conductivity meters, this system is able to detect conductivity range 0-2000us/cm of original water and purified water produced on-line.

M、 Time-lag Relay

High precision digital display relay mainly ensures accurate time lag start of automatic washing and high pressure pump.
