Pharmaceutical water treatment equipment - Pharmaceutical purified water treatment equipment

　Purified water process

Raw water → raw water booster pump → multi-media filter → activated carbon filter → water softener → precision filter → first stage reverse osmosis → pH regulating device → intermediate water tank → second stage reverse osmosis → purified water tank → delivery pump → ultraviolet sterilizer → microporous filter → water point (recommended process).

Raw water → Raw water booster pump → Multi media filter → Activated carbon filter → Softener → Precision filter → First stage reverse osmosis → Intermediate water tank → Intermediate water pump → Ion exchange equipment → Purified water tank → Transport pump → UV sterilizer → Micro porous filter → Water point (traditional process).

　Requirements for process water

The process water used by pharmaceutical production enterprises mainly refers to the water used in bottle washing, ingredient preparation and other processes in the production of formulations, as well as the water used in refining and washing processes in the production of active pharmaceutical ingredients. The name of water should avoid being related to its manufacturing process, such as deionized water, desalinated water, and distilled water. This means that the manufacturing process of water is decoupled from its name, and water is classified based on quality indicators from a chemical and microbiological perspective.

Injection water is generally prepared by distillation (as well as reverse osmosis and ultrafiltration) using purified water, and is free of pyrogen. Since the preparation process of pure steam is the same as that of using distilled water to prepare injection water, the same multi effect distilled water machine or a separate pure steam generator can be used. Therefore, pure steam is discussed together with injection water.

　Purified water standard

The requirements for water used in drug production refer to the purified water standard and the purified water testing method.

　Definition of Secondary Reverse Osmosis:

Secondary reverse osmosis is a purification process that uses the water produced by primary reverse osmosis as raw water for a second reverse osmosis, with a conductivity of ≤ 3 μ s/cm. It has been widely used in drinking purified water. Reverse osmosis technology is commonly used for pre desalination treatment, which can reduce the load on ion exchange resin and decrease the amount of regenerant used in the resin. Therefore, it not only saves operating costs, but also benefits environmental protection. The unique water treatment equipment of reverse osmosis cannot be achieved by other water purification methods such as distillation, electrodialysis, ion exchange, etc.
