How to prevent Perlite resin from being contaminated by organic substances? 1. After long-term use, Perlite mixed bed ion exchange resin may be contaminated by some substances, such as iron contamination and organic matter contamination. Before taking measures to deal with it, an analysis should be conducted and appropriate methods can be adopted for treatment. The causes and phenomena of organic contamination of Polite cation exchange resin: When there are oils, humic acid and other organic substances in the water, it is very easy to form an oil film on the surface of the resin, blocking the micropores of the resin and sealing the active exchange groups, thereby seriously affecting the performance of the resin. When the Polite cation exchange resin is contaminated by organic substances, it will show a darkening and blackening of color, a decrease in resin density and a significant drop in exchange capacity, leading to resin stratification

How to prevent Perlite resin from being contaminated by organic substances

1. Polite mixed bed ion exchange resin

After long-term use, it may be subject to some contamination, such as iron contamination and organic matter contamination. Before taking measures to deal with it, an analysis should be conducted and appropriate methods can be adopted for treatment.

The causes and phenomena of organic pollution caused by Polite cation exchange resin,When there are oils, humic acid and other organic substances in water, it is very easy for an oil film to form on the surface of the resin, blocking the micropores of the resin and sealing the active exchange groups, thereby seriously affecting the performance of the resin.

When the Pulaite cation exchange resin is contaminated by organic matter, it will show a darkening and blackening of color, a decrease in resin density and a significant drop in exchange capacity, resulting in caking of the resin layer and a deterioration of the effluent quality. These phenomena are extremely similar to iron contamination. To distinguish them, take a small amount of resin sample and add it to a test tube, then add a small amount of water and shake it continuously for two to five minutes. If a rainbow phenomenon is observed, it can be determined that the resin has been contaminated by organic matter. Another method is to add sodium chloride with a concentration of 5% to 10% to the sample test tube. After leaving it for two to four hours, if the solution turns yellowish-green and the resin color becomes lighter, it can be proved that the resin has undergone iron contamination.

Ii. Treatment Methods for Organic Pollution caused by Perlite cation Exchange Resin

Mix a sodium chloride solution with a concentration of 8% to 10% with a sodium hydroxide solution of 2% to 4%.That is to say, industrial salt used in water softeners, water softening equipment, and fully automatic water softening equipment for boilersHeat between 40 and 50 degrees Celsius to allow the resin to undergo two to four alkaline washes, each lasting about six to eight hours, with water rinsing in between.

Special attention should be paid here to prevent the Purite cation exchange resin from being contaminated by organic substances. It should be used in feed processing systems, such as pretreatment, coagulation, and filtration systems, which can maintain a good operating state for a long time.

: 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.
