A system for preparing purified water

Abstract

The invention relates to a system for preparing purified water. The system comprises a water storage tank, wherein the water storage tank is sequentially connected with a full-automatic sand filtering device, a full-automatic carbon filtering device and a full-automatic ultrafiltration device; an electric heating device and a temperature sensor are arranged in the water storage tank; a constant temperature tank with a sandwich structure is connected between the water storage tank and the full-automatic sand filtering device, a hot water pipeline is arranged on the sandwich structure of the constant temperature tank, and a booster pump is arranged at the water inlet end of the full-automatic ultrafiltration device; the full-automatic ultrafiltration device is connected with a purified water tank I and a purified water II, the purified water II is provided with a clean water delivering pipe and a water return pipe, the water return pipe is provided with a by-pass pipe, and the by-pass pipe is provided with a water quality testing device. With the adoption of the system, the problem that the quality of products is influenced as the probability of pollution to pipelines in a clean region is high which is caused by the fact that the traditional water treating system is slow in filtering speed, is solved.

Description

Technical field [0001] The invention relates to the field of biological production of water, in particular to a system for preparing purified water. Background technique [0002] In pharmaceutical factories such as vaccines or biological preparations, research institutes, pharmaceutical factories that use cell culture, food factories or research institutes, blood preparation factories, etc., a large amount of purified water is used in the experiment and production process, such as the production pipeline Circulation, cleaning equipment, experimental devices, liquid preparation, etc., therefore, the preparation of purified water and the circulation system have become indispensable devices in the biopharmaceutical industry. The biopharmaceutical industry has high requirements for purified water, and generally requires multi-stage filtration, which generally includes sand filtration, carbon filtration, and membrane filtration. In the process of filtration, tap water of different wat...
