Product Introduction
Pure water equipment, simply put, is the equipment used to produce pure water. Pure water is widely used by us in: daily drinking, chemical industry, medical care, breeding, planting, food, beverages, etc. The following will briefly introduce the components of the equipment and the process of producing pure water for you. We hope it can provide some help for you to understand this industry.
How is the product performance of the integrated wastewater treatment equipment
Nowadays, industrial development is extremely rapid, and industrial products have become indispensable in daily life. The more complex the process of general industrial products is and the better the product performance is, the higher the requirements for process water will be. The integrated wastewater treatment equipment was developed in response to industrial demands, and the quality of the process water it produces fully complies with industry standards.
① Mixed-bed ion exchange purification column
The mixed-bed ion exchange purification column is composed of anion exchange resin and cation exchange resin in a certain proportion. Cation exchange resin uses its H+ exchange to remove cations from water, while anion exchange resin uses its OH- exchange to remove anions from water. In mixed bed resin, the H+ exchanged out combines with OH- to form H2O. Therefore, mixed bed ion exchange purification columns can be used to deeply remove trace ions remaining in RO pure water. The mixed-bed ion exchange purification system in small laboratory ultrapure water machines is usually for single use. The Yongjieda mixed-bed ion exchange purification system uses original imported nuclear-grade mixed-bed resin. The resistivity of its produced water can reach 18.2 m · cm.
②EDI device
Continuous electro-deionization (EDI, short for Electrodeionization) is a process in which mixed-bed ion exchange resins adsorb cations and anions in feed water. Meanwhile, these adsorbed ions pass through the cation and anion exchange membranes respectively under the action of direct current voltage and are continuously removed. This new technology can replace the traditional ion exchange (D), producing ultrapure water of over 10 mk.cm. The major advantage of EDI deep desalination is that it can operate stably for a long time without the need for acid and alkali to regenerate anion and cation resins. It is very suitable for central ultrapure water preparation systems with a water production capacity of over 100 liters. The water quality is stable, and it will greatly reduce operating costs. The TOC will also be lower and more stable. The resistivity of the water produced by the Yongjieda EDI device is usually about 15 to 18 m0.cm.
③ Pyrogenic removal ultrafiltration membrane
Ultrafiltration for pyrogen removal has been widely used in the modern pharmaceutical industry. The pore size of Ultrafiltration (UF for short) membranes lies between that of reverse osmosis and microfiltration (about 0.01 to 0.1 μ m), and is usually expressed by the minimum molecular weight retained. The pyrogenic ultrafiltration membrane of the integrated wastewater treatment equipment adopts a polysulfone membrane with a molecular weight cut-off of 5000 Daltons, which can thoroughly remove pyrogens (whose small molecular weight is usually greater than 7000) and various microorganisms from water.
