When we are using reverse osmosis RO water system to filter our drinking water what we should Keep in mind is that we should control the reverse osmosis pressure in a proper range, because whether the reverse osmosis pressure is too high or too low it will affect the filtration effect of the reverse osmosis. If There is low pressure in reverse osmosis it can not even start. Besides low pressure in ro system could result in no water coming out of the reverse osmosis system.SO what is the perfect pressure range of the reverse osmosis system? why what cause the low pressure in reverse osmosis ro system?
1.The pressure range for reverse osmosis ro systemNormally, the perfect pressure of the reverse osmosis system is required to be 0.2-0.5MPa. First, in order to ensure the effect of regenerative salt absorption, the pressure needs to be greater than 0.2MPa. Because the automatic reverse osmosis water treatment equipment relies on hydraulic pressure to form negative pressure for salt extraction, the upper end pressure directly affects the speed and effect of salt extraction. Usually, under the pressure below 0.18MPa, the salt absorption effect is significantly reduced. However, when the pressure reaches 0.5MPa or higher, the salt absorption effect of the reverse osmosis system will certainly be better, but at this time, the pressure of the pipeline is too high, this could lead to easy leakage of each joint of the reverse osmosis. In addition, if the pressure is too high, the internal components of the multi-way valve will be over-pressurized, which may cause the multi-way valve to work inaccurately, thereby directly affecting the filtration effect of the ro system. Therefore, the perfect working pressure of the reverse osmosis system is 0.2-0.5MPa, which will affect the normal operation of the reverse osmosis system if it is higher or lower than this range.
2.Why does my reverse osmosis system has low pressure?
①.Unstable voltage cause low water pressure in reverse osmosisVoltage instability will cause insufficient power supply to the reverse osmosis system, making the entire equipment unable to work properly. As a result, the water pressure in reverse osmosis will be low.
②. Problems with the reverse osmosis itself will cause the low water pressure on reverse osmosis systemIf the reverse osmosis system leaks, the water flow rate will be low as a result, and if the internal problems are not fixed in time, the water pressure and water flow on reverse osmosis system will be insufficient.
③.Faulty booster pump result in low pressure in ro systemSpecial inspection and maintenance personnel can be asked to check whether the booster pump of the reverse osmosis system is faulty. If the inlet water pressure of the booster pump is insufficient or the pump part leaks water or air, it will directly cause the low pressure in ro system.
④. The pressure of the precision filter is not enoughWhen the pressure of the precision filter is insufficient, the reverse osmosis pressure will also be unstable. At this time, we have to check the original pump to see if the original pump pressure is not enough. If the original pump pressure is insufficient, a booster pump is required to ensure the water pressure.
⑤. The filter element blocked by dirt
If the fine filter is clogged with dirt, insufficient water flow can result in reverse osmosis low pressure.
In addition, the working pressure of the reverse osmosis is directly related to the salt content and temperature of the influent water. If the conventional water source is tap water, river water, groundwater, and reservoir water, the working pressure of the reverse osmosis is generally 8-12bar, and if it is a seawater source, the working pressure is generally about 45bar.And sometimes if the temperature is to low the pressure in reverse osmosissystem will be low as well.
