A multi-stage filtration water treatment system

Abstract

The invention relates to a multi-stage filtered water treatment system which comprises a water storage tank and a tap water inlet pipe connected with the water storage tank, wherein the water storage tank is connected with a full-automatic sand filter, a full-automatic carbon filter and a full-automatic ultrafiltration device; the full-automatic ultrafiltration device is connected with a purified water tank; the purified water tank is connected with water treatment equipment; an electric heating device and a temperature sensor are arranged inside the water storage tank; a constant-temperature tank adopting a sandwich structure is connected between the water storage tank and the full-automatic sand filter; a hot water pipeline is arranged on the sandwich structure of the constant-temperature tank; a booster pump is arranged at a water inlet end of the full-automatic ultrafiltration device; a flowmeter is arranged at a water outlet end of the full-automatic ultrafiltration device. Through the arrangement of the water storage tank with the electric heating device and the constant-temperature tank with the sandwich structure as well as the booster pump at the water inlet end of the full-automatic ultrafiltration device, the pressure and the temperature in filtering are guaranteed to be in the optimal range, the optimal filtering speed is achieved, and the problem of relatively slow filtering speed of a conventional purified water circulation system is solved.

Description

technical field [0001] The invention relates to the field of purified water preparation, in particular to a multistage filtered water treatment system. Background technique [0002] In pharmaceutical factories such as vaccines or biological agents, research institutes, pharmaceutical factories using cell culture, food factories or research institutes, blood preparation factories, etc., a large amount of purified water will be used in the experiment and production process, such as for the production of pipelines Circulation, cleaning equipment, experimental devices, liquid preparation, etc. Therefore, the preparation of purified water and circulation systems have become indispensable devices in the biopharmaceutical industry. The biopharmaceutical industry has high requirements for purified water, and generally requires multi-stage filtration, generally including sand filtration, carbon filtration, and membrane filtration. During the filtration process, tap water with differe...
