Overview of Demineralized water Equipment for Pharmaceutical Production
The demineralized water equipment for pharmaceutical production is a water treatment device specially designed and produced for the production water in the pharmaceutical industry. The water quality of the effluent from this equipment can meet the production requirements of the pharmaceutical industry. There are various process flows for desalinated water. Customers can choose the suitable water treatment equipment according to their actual production needs. No matter which process flow it is, the effluent quality does not change much. This article mainly introduces the advantages and disadvantages of desalinated water equipment with different process flows.
The advantages and disadvantages of the three process flows of demineralized water equipment
1Ion exchange method: The use of ion exchange resin has the advantages of low initial investment and less space occupation. However, the disadvantages are that it requires frequent ion regeneration, consumes a large amount of acid and alkali, and has a certain destructive effect on the environment.
2Reverse osmosis+Mixed bed method: Reverse osmosis is adopted+Mixed bed, which is currently a relatively economical process for producing ultrapure water, requires regeneration with acid and alkali to continuously produce ultrapure water, but it has a certain degree of damage to the environment. Its advantage lies in that the initial investment is relatively cost-effective. This is also a process that many thermal power companies can accept.
3,EDIMethod: Reverse osmosis is adopted as pretreatment and then combined with electro-deionization(EDI)This device is currently the most economical and environmentally friendly process for preparing ultrapure water. It can continuously produce ultrapure water without the need for acid and alkali regeneration, causing little damage to the environment. Its drawback lies in the fact that the initial investment is relatively too expensive compared to the above two methods.
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.
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 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.
