Abstract

The invention relates to an integrated device for removing water hardness, which comprises a hardness-removing system and a suspended substance-removing system, wherein the hardness-removing system and the suspended substance-removing system are integrated, the hardness-removing system is positioned at the lower part of the device for removing water hardness, the suspended substance-removing system is positioned above the hardness-removing system, and the bottom of the suspended substance-removing system, which is close to the hardness-removing system, is provided with an inclined plate or an inclined pipe, so that particles generated by hardness removal can be blocked below the suspended substance-removing system positioned at the upper part.

Description

technical field [0001] The invention relates to an integrated device for removing hardness in water. Background technique [0002] In the process of water resource reuse, reverse osmosis membrane (RO) is often used to filter and separate water bodies. Reverse osmosis can separate raw water into two streams of water, namely permeate (clear liquid) and concentrated liquid. Because the reverse osmosis membrane has the function of intercepting substances other than water molecules, the water quality of the clear liquid is close to pure water, while the concentrated liquid concentrates most of the pollutants. Due to the nature and performance limitations of the reverse osmosis membrane, the pollutants ( Including Ca 2+ , Mg 2+ , SiO 2 etc.) When the concentration reaches a certain level, it will have great side effects on the water production volume, water quality, membrane performance, membrane life, and system energy consumption. Therefore, the reverse osmosis system has a ...
