1000LPH FRP Reverse Osmosis Mineral Water RO Water Treatment System Filter Plant

Reverse osmosis water treatment equipment usually consists of three parts: raw water pretreatment system, reverse osmosis purification system, and ultra-purification post-treatment system. The main purpose of pretreatment is to make the raw water meet the influent requirements of the reverse osmosis membrane separation module and ensure the stable operation of the reverse osmosis purification system. The reverse osmosis membrane system is the most economical and efficient purification method to remove more than 98% of ions, organic matter and 100% of microorganisms (theoretically) in raw water at one time. The ultra-purification post-treatment system further removes trace ions, organics and other impurities remaining in reverse osmosis pure water through a variety of integrated technologies to meet the final water quality index requirements for different purposes.

Working Principle of Reverse Osmosis Water Treatment System:

When a pressure greater than osmotic pressure is applied on the saltwater side of the membrane, the flow of water is reversed and the water in the saltwater flows into the fresh side, a phenomenon called reverse osmosis.

Technical Specifications of Reverse Osmosis Water Treatment System:

Process flow of reverse osmosis water treatment system:

Raw water → original water tank → original water pump → multi-media filter (quartz sand filter)→ activated carbon filter → soft water processor → precision filter → high pressure pump → first stage reverse osmosis (RO) device → pure water tank → high pressure pump → second stage reverse osmosis → ultraviolet sterilization device → water point



Preprocessing:
The pretreatment system of reverse osmosis water treatment equipment usually consists of polypropylene fiber (PP) filter and activated carbon (AC) filter. For raw water with higher hardness, a softening resin filter needs to be installed. The PP filter element can efficiently remove pollutants such as mechanical particle impurities, rust and large colloids above 5 μm in the raw water, and protect the subsequent filter. It is characterized by large dirt holding capacity and low price. AC activated carbon filter element can efficiently adsorb residual chlorine and some organic substances and colloids in raw water, and protect the polyamide reverse osmosis composite membrane from residual chlorine oxidation. The softening resin can remove most of the calcium and magnesium ions in the raw water, prevent the subsequent RO membrane surface fouling and blockage, and improve the water recovery rate.

FAQ:

1, What are the inlet water quality requirements for ro water treatment system membrane components?

2. What is the material of ro water treatment system membrane?

Acetate membrane (CA) : mainly because of its resistance to chlorine, so it is still durable. But its suitable pH range is small, easy hydrolysis

Aromatic polyamide membrane (PA) : water almost can not have chlorine, only through a variety of pretreatment chlorine.


3. RO water treatment system configuration:

First-stage multi-stage process: if the recovery rate is not achieved in the first stage (50-65% in the first stage and 65-75% in the second stage), the multi-stage tandem filtration can be used. The effective cross-sectional area of each segment decreases. 2:2 and 2:3 and 4:2:1

Multi-stage process: when the first stage process cannot meet the effluent quality requirements (the first stage is generally ≤20μs/cm), the product water of the first stage process is sent to another reverse osmosis unit.

The arrangement of membrane components can be divided into series and parallel.
