The Glegg Water Management
2. Competing Resins Technology: As mentioned in the material, traditionally, caustic chemicals were used to flush away the impurities and regenerate these resins. In these systems, the mixed-bed ion-exchange stage was preceded by separate cation and anion exchange vessels. As applications became more demanding, it was clear that chemically regenerated ion exchange systems had limitations. ” “Ion-exchange resins are typically styrene and divinylbenzene copolymers cross-linked to form beads between 0.03 and 1.0 mm. The beads are converted into cation-exchange resins through a sulfonation process, or anion-exchange resins through chloromethylation.” “EDI removes ions from water using conventional ion-exchange resin, but with a significant benefit--an electrical current that regenerates the resin bed continuously, eliminating entirely the need for periodic chemical regeneration.”
3. The key sectors listed in the Power Generation of Exhibit 2 are power plans, chemical industry, manufacturing, petroleum industry and paper industry. They share in common that they all need of quality water treatment equipment that is with high flow rate. And these key sectors are all facing the challenges of environmental protection, which was drawing attention from either the public or the government. Hence, there is believed to be a potential market in all the sectors under power generation.
However, different industries may have different requirements on their needs and standard of water treatment equipment. Followings are those influencing buying decisions: In the material, it says that the typical power generation water treatment
