The reasons for the abnormal water production of these reverse osmosis devices are easily overlooked

Released Date: Aug 14,2015 Article Source: Yuanlai Water Treatment

In water treatment, reverse osmosis technology is a commonly used technique. Based on the principle of reverse osmosis, it separates other substances from water through anti-osmosis membranes. However, as the usage increases, reverse osmosis equipment will gradually age and the water treatment effect will decline. In fact, we can initially determine the abnormal water production of reverse osmosis equipment by checking the quality of the influent water. Residual chlorine Residual chlorine refers to the available chlorine remaining in water after it has been chlorinated and in contact for a certain period of time. It can be classified into combined residual chlorine (referring to the compounds of chlorine and ammonia in water, including NH2Cl, NHCl2 and NHCl3). Free residual chlorine refers to ClO-, HClO, Cl2, etc. in water. Generally, the composite membrane of reverse osmosis equipment is not allowed to contain residual chlorine. Iron content can be detected by the iodometric method

Residual chlorine

Residual chlorine refers to water that has been chlorinated,The available chlorine remaining in the water after a certain period of contact. It can be classified into combined residual chlorine(Compounds of chlorine and ammonia in water includeNH2Cl,NHCl2andNHCl3Three types);Free residual chlorine refers to the chlorine in waterClO-,HClO,Cl2Such asResidual chlorine is generally not allowed in the composite membranes of reverse osmosis equipment. The iodometric method can be adopted for detection

Iron content andPHvalue

The oxidation rate of iron depends on the iron content, the concentration of dissolved oxygen in water andPHValuePHThe higher the value, the faster the oxidation rate. Therefore, reduce the iron content andPHThe value can prevent oxidation.

The size of the incoming particles

Reverse osmosis equipment is not allowed to exceed5μmThe particulate matter will enter the high-pressure pump and reverse osmosis membrane module; otherwise, it will damage the equipment.

SDIAnd turbidity

Feed water for reverse osmosis equipmentSDILess than5The smaller, the better. The turbidity should be less than0.2NTUThe maximum allowable turbidity is1NTU.

Oil and fat

Check the oil and grease in the water. Sometimes, abnormal water production of the osmosis equipment can also be caused by grease.

Organic matter

The organic matter in water pairsROThe impact of reverse osmosis membranes is complex. Some organic substances have little effect on the membranes, while others may cause organic contamination of the membranes.

Scaling

Scale often forms in reverse osmosis equipment, which can affect the treatment effect and prevent itCaCO3,CaSO4,SrSO4,BaSO4,CaF2andSiO2To reduce the probability of abnormal water production in reverse osmosis equipment by scaling.

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
