1Overview of Double stage Reverse Osmosis Pure Water Equipment

Reverse osmosis is the heart of the system, and the maturity and rationality of its design not only directly determineROsystemWhether it can meet the design requirements and is related toROfilmThe service life, afterROThe water treated by the device can remove the vast majority of inorganic salts and almost all organic matter and microorganisms.

ROThe device has the advantages of no phase change, high desalination rate, small equipment volume, self controlled operation, strong applicability, wide application range, and no environmental pollution during the water quality separation process. This system adoptsSecondary reverse osmosis desalination systemRemove the majority of ions, particles, organic matter, etc. from water to achieve purified water quality standards.

IIProcess flow of two-stage reverse osmosis pure water equipment:

Groundwater or tap water——Raw water booster pump——quartz sand filter——Activated carbon filter——Softening water device——10umPrecision filter——5umPrecision filter——Primary high pressure pump——First level reverse osmosis——Intermediate water tank--Secondary high-pressure pump——Secondary reverse osmosis——Pure water tank——Finished water.

IIIDouble stage reverse osmosis pure water equipmentTechnical Parameter

Outlet water quality:ROSystem design desalination rate≥98%When the conductivity of the raw water is less than400μs/cmAt that time, the quality and conductivity of the effluent water2-5us/cm.

Process Description:The pre-treatment adopts four stages: mechanical precipitation filtration, carbon adsorption filtration, cation softener, and post security precision filter;ROThe components are imported from the United StatesDOW-ROReverse osmosis membrane or imported from KoreaCSM-ROReverse osmosis membrane. The main content of automatic operation of reverse osmosis includes high pressure and low pressure automatic control;Automatic shutdown with no water and full water;Concentrated water timed automatic discharge;Online automatic detection of water quality;Automatic discharge alarm for unqualified water;Timed medication washing instruction;Fault prompts, etc.

4Double stage reverse osmosis pure water equipmentcharacteristic

1After startup, the device realizes automatic membrane flushing function, and the flushing time2-10Minutes adjustable.

2The equipment is equipped with a wastewater reflux device, which can recycle water, improve water utilization efficiency, and save water costs.

3Low pressure protection system, when the source water pressure is insufficient or there is no source water, the equipment will automatically shut down to protect the safety of the high-pressure pump and equipment.

4After the pure water tank is full, the equipment can automatically shut down.

5The equipment is equipped with a cleaning and maintenance system, which can be regularly cleaned and maintained to extend the service life of the reverse osmosis membrane3-5Year.

6The equipment adopts a stainless steel frame structure to achieve no hygiene dead corners, no corrosion, and use10-20The year is still as new as ever.

7Dual stage reverse osmosis equipmentEquipped with multiple regulating valves, it can achieve dual stage effluent, single-stage effluent, or simultaneous effluent of both stages, making the quality of the produced water diversified.

8Reverse osmosis equipment can be used in conjunction with mineral water equipment(Mountain spring water equipment)Supporting use, reducing investment costs, and improving water resource utilization efficiency.

9The equipment is basically achievable24Unattended operation for hours.

10Equipped with an online water quality detector to observe the effluent quality at any time.

5Common questions in the operation of two-stage reverse osmosis pure water equipment

1The service life of reverse osmosis membrane: Reverse osmosis membrane is a relatively expensive component in a set of equipment, and its service life is related to the operating cost of the entire equipment;The normal service life of membrane components is over three years, but the prerequisite is whether the selection of the entire equipment is reasonable, the operation method is appropriate, the materials are replaced in a timely manner, and the membrane components are cleaned and maintained regularly according to the situation

2The conductivity of the effluent water quality increases: The condition of the equipment at each stage needs to be recorded in a timely manner. If the conductivity slowly increases and the desalination rate slightly decreases, it is a normal phenomenon. It only needs to be maintained in a timely manner according to the reason for the increase in conductivity;If there is a sudden increase in conductivity, it is necessary to determine whether the filter is due to component damage, significant changes in raw water quality, or the failure of some pre-treatment material

3After washing the reverse osmosis membrane, there is little change in water quality:aAre the components damagedbHas a certain pre-treatment material failedcWhen washing the membrane, it was not clear which species and degree of contamination the membrane components were contaminated with, and targeted measures were taken accordingly

4Excessive system pressure difference: Depending on the different membrane components, the system pressure difference should be controlled within a reasonable range to avoid damage to the membrane components

5Low utilization rate of raw water and excessive discharge of concentrated water: whether the inflow flow is sufficient, whether the pressure meets the material's operating conditions, whether the equipment design is reasonable, etc
