How does temperature affect water production?

The higher the temperature, the higher the water production, and vice versa, when operating at a higher temperature, the operating pressure should be lowered to keep the water production unchanged, and vice versa.

Separation capacity of drinking water RO system membrane technology:

Reverse osmosis is currently a relatively accurate liquid filtration technology. RO reverse osmosis membrane can retain inorganic molecules such as dissolved salts and organic compounds with molecular weight greater than 100. On the other hand, water molecules can freely pass through the RO membrane, and the removal rate of typical soluble salts is high.

Technical specifications of drinking water RO system:

Drinking water RO system work flow:

raw water - raw water tank - raw water booster pump - quartz sand filter - activated carbon filter - scale inhibitor dosing equipment - precision filter - first-stage high pressure pump - first-stage reverse osmosis Host - intermediate water tank - secondary high pressure pump - secondary reverse osmosis host - disinfection system - production water.

What contaminants do drinking water reverse osmosis systems remove from water?

Drinking water reverse osmosis systems can remove up to 99% more dissolved salts (ions), particles, colloids, organics, bacteria and pyrogens from feed water (although RO systems should not be relied on to remove 100% of bacteria and viruses). Reverse osmosis membranes filter contaminants according to their size and charge. Any contaminant with a molecular weight greater than 200 is likely to be rejected by a properly functioning reverse osmosis system (water, by contrast, has a molecular weight of 18). Similarly, the higher the ionic charge of the pollutant, the more likely it is not to pass through the RO membrane. For example, sodium ions have only one charge (univalent) and are not repelled by RO membranes like calcium ions, which have two charges. Again, this is why RO systems do not remove gases such as CO2 very well, as they are not highly ionized (charged) and have very low molecular weight in solution. Because the RO system does not remove gases, the pH of the percolated water may be slightly lower than normal as CO2 is converted to carbonic acid, depending on the level of CO2 in the influent.

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.
