Preventing Pure Water from Secondary Contamination (As Shown in the Diagram):

The biotechnology industry imposes strict requirements not only on the piping of water purification equipment but also on the water supply pipelines. During design, clamp-type stainless steel pipelines must be used. When laying the pipelines, a U-shaped installation method is required; otherwise, it will be deemed unacceptable.

Generally speaking, the minimum requirement for process water in the biotechnology industry is water produced by a two-stage reverse osmosis system, with the produced water having a conductivity within 5 μS/cm. Depending on the raw water conditions, the conductivity is typically between 2 and 3 μS/cm, or even lower.

Different biotechnology organizations have varying requirements for water quality. For biotechnology industry applications and the production of oral liquids, ultrapure water must be used as process water. This represents the highest current standard, requiring a resistivity above 17 MΩ·cm. The process used in the water purification equipment combines two-stage reverse osmosis with EDI and a polishing mixed bed, or alternatively, one-stage reverse osmosis with a two-stage mixed bed. The maintenance costs associated with different processes vary: the former involves higher initial equipment investment but lower routine maintenance costs, while the latter has lower initial equipment investment but higher routine maintenance costs.

Currently, however, we more commonly use a two-stage reverse osmosis system combined with EDI and a polishing mixed bed. This approach avoids frequent replacement of ion exchange resins, resulting in more stable operation and lower overall comprehensive costs.
