RO System Water Purification Reverse Osmosis Water Treatment

Working principle

A special high-pressure water pump is used to pressurize the raw water to 6-20 kg, so that the raw water can penetrate through the reverse osmosis membrane with a pore size of only 0.0001 micron under pressure. Chemical ions, bacteria, fungi, and virions cannot pass through, and are discharged with the wastewater. Only water molecules with a volume less than 0.0001 microns are allowed to pass through.

Pretreatment system

The purpose of the

aqua pure ro system

is to improve the water supply conditions to meet the water inlet requirements of the reverse osmosis system, thereby protecting the reverse osmosis host and extending the service life of the membrane. In the aqua pure ro system. It is often necessary to carry out pretreatment design for different water quality, the most common is the multi-media filter (removing suspended particles with a diameter greater than 10um) + activated carbon (removing odor, residual chlorine, heavy metal ions, organic carcinogens, etc.) + Antiscalant dosing device (or softening device) (greatly reduce the scale formation of calcium, magnesium and other scaling substances in the system) + precision filter (filtration accuracy of 5um, further remove residual particulate matter in the water) to form a pretreatment system.

Reverse osmosis system

Mainly include system pump, aqua pure ro system (reverse osmosis membrane and membrane shell, frame, electric control box), flushing/cleaning device and intermediate water tank.

Advantages

*Continuous operation, stable water quality

*No need to regenerate with acid and alkali

*No downtime due to regeneration

*Save water for backflushing and cleaning

*Ultra-pure water is produced with high yield, the yield can reach 95%

*No reclaimed sewage, no sewage treatment facilities, no acid-base storage and acid-base dilution transportation facilities

*Reduce the building area of the workshop, use it safely and reliably, and avoid workers contacting acid and alkali.

*Reduce operation and maintenance costs

*Simple installation, low installation cost

Disadvantage

The salt removal rate of the aqua pure ro system is generally 98%-99%. Such a salt removal rate can meet the requirements in most cases, but in the electronics industry, ultra-high pressure boiler feed water, and individual pharmaceutical industries require pure water It may be higher. At this time, the single pass reverse osmosis equipment cannot meet the requirements. The following methods can further purify the reverse osmosis water, which has met the requirements.

*Two pass reverse osmosis----Single pass reverse osmosis pure aqua is subjected to a reverse osmosis treatment again to improve the purity of the pure water

*The combination of reverse osmosis and EDI can produce ultrapure aqua with a smaller plant and lower operating costs
