What are the difficulties in the maintenance of industrial water purification equipment


Industrial water purification equipment is widely used in laboratories, hospitals and some large factories. In these areas, the water quality requirements are generally high, and the water needs to be treated by water purification equipment before it can be put into use. So what are the maintenance difficulties of this kind of industrial water purification equipment?
Membrane clogging. If the prefilter is not replaced or cleaned for a long time, the water quality inside the machine is far worse than that before entering the machine. The raw water quality is poor, but the proportion of wastewater is small, resulting in the blockage of waste water solenoid valve or flushing combination valve, and then no wastewater is produced, or there is very little waste water, which leads to the blockage of membrane and shorter service life.
The filter element is blocked. One of the common faults of the equipment is the blockage of the filter element. It is very important to replace the filter element for prolonging the service life of the equipment.
There is something wrong with the transformer. If there is a fault in the transformer, it can not provide the voltage required for the normal pressurization of the pump, so the speed will be slow, the increased pressure will be small, and the pressurization will be small.
Naturally, the pressure required for the tap water to pass through the RO membrane will not be reached. At this time, the water production will be slow. After eliminating the factors of pump and membrane, it is necessary to replace a new transformer.
Water tank material. Because of its high purity and almost no impurities, ultrapure water is easy to absorb pollutants from the external environment and cause pollution. If the water storage tank we use is low-grade plastic, it will be easier to dissolve some organic matters, thus increasing the conductivity of water, leading to the decline of water quality.
