Analyzing the water pressure of reverse osmosis water treatment equipment

Water pressure range of reverse osmosis water treatment equipment

The pressure is greater than 0.2MPa to ensure the salt absorption effect of regeneration. Because fully automatic reverse osmosis water treatment equipment uses hydraulic pressure to generate negative pressure to extract salt water, the pressure at the upper end of the salt suction device directly affects the speed and effectiveness of salt suction. Generally speaking, if the pressure is below 0.18MPa, the salt suction effect will significantly decrease.

If the pressure is greater than 0.5MPa, the salt absorption effect of the reverse osmosis water treatment equipment can be guaranteed, but at this time, the pressure on the pipeline is too high, and leakage is prone to occur at each joint. In addition, due to water pressure causing excessive pressure on the internal components of the multi way valve, it may cause inaccurate operation of the multi way valve, which directly affects the working effect.

Possible problems with reverse osmosis water treatment equipment under high pressure

1. Resin leakage during backwashing

When the water pressure is too high, the degree of resin expansion during backwashing may exceed the calculated value. If the pore size of the upper water distributor is large enough, it is very easy to cause resin to enter the multi way valve from the top and flow out along the drainage pipeline, resulting in resin leakage.

2. Excessive water injection

When the water pressure is too high, during the salt water reinjection stage, more water will be injected into the salt tank, which may cause abnormal high water level in the salt tank of the reverse osmosis water treatment equipment, and sometimes even cause salt water overflow.

3. Abnormal valve action and unstable water outlet indicator

When the water pressure is too high, a pressure exceeding the original calculated value may be formed on one side of the piston or valve plate of the multi way valve. This may cause the original motor of the reverse osmosis water treatment equipment valve body to not be smooth enough when driving the valve action, resulting in incomplete valve action and other situations. This may form some channels inside the valve, and untreated water flows through these channels to the outlet, causing unstable water outlet indicators.

What is the relationship between the operating status of reverse osmosis equipment and water pressure?

When the water pressure is too high, injecting more water into the salt tank may also cause the water level in the salt tank to be abnormally high, and may even lead to the overflow of salt water. The valve action is abnormal, and the water indicator is not qualified. When the water pressure is too high, a pressure greater than the original calculation will be formed on one side of the multi way valve piston or valve plate, causing the original motor driven valve movement of the body to be not smooth enough, causing the valve action to be not in place, etc. This may lead to some channels inside the valve, causing untreated water to flow out through these channels, causing unstable water outlet indicators. The regeneration effect is not good. When the water pressure is too high, the salt absorption rate accelerates, and the effective regeneration time is greatly reduced. Reverse osmosis pure water equipment cannot achieve good regeneration effect.
