With the acceleration of industrialization, inorganic salt wastewater has become one of the important environmental pollution. These wastewaters contain a large amount of inorganic salts, such as sodium chloride, sodium sulfate, calcium chloride, etc., which have a serious impact on the environment and ecology. Therefore, the R&D and application of inorganic salt wastewater treatment equipment are particularly important.
The main goal of an inorganic salt wastewater treatment plant is to remove the inorganic salts from the wastewater so that it meets the discharge standard or reuse standard. These devices can employ a variety of techniques such as precipitation, filtration, adsorption, ion exchange, etc. Among them, membrane separation technology, as an efficient and environmentally friendly technology, has been widely used in the treatment of inorganic salt wastewater.
Membrane separation technology uses semi-permeable membranes to separate inorganic salts and moisture in wastewater through the diffusion of membranes. According to the size of the membrane pore size, it can be divided into different types such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis. Among them, reverse osmosis technology is the most widely used membrane separation technology, which can effectively remove impurities such as ions, organic matter and microorganisms in water.
The application range of inorganic salt wastewater treatment equipment is very wide, involving chemical, food, pharmaceutical, metallurgical and other fields. In the chemical industry, inorganic salt wastewater is mainly used in the production process of cooling water, cleaning water, etc., these wastewater contains a large amount of salt and other impurities, which need to be treated before discharge or reuse. In the food and pharmaceutical industry, inorganic salt wastewater is mainly used in the washing, cooling and process water in the production process, etc., and the water quality of these wastewater requirements is high, and it needs to be purified by efficient treatment equipment. In the metallurgical industry, inorganic salt wastewater is mainly used in the production process of cooling water, washing water and process water, etc., these wastewater contains a large number of metal ions and salts, and needs advanced treatment to meet the discharge standards.
The development trend of inorganic salt wastewater treatment equipment is mainly focused on the following aspects: first, improve treatment efficiency, reduce energy consumption and cost; the second is to develop new membrane materials and components to improve the separation effect and service life of membranes; the third is to strengthen the application of automation and intelligent technology to improve the degree of automation and operational stability of equipment; Fourth, strengthen the miniaturization and integrated design of equipment to facilitate the transportation and installation of equipment.
In a word, inorganic salt wastewater treatment equipment is an important part of environmental protection and sustainable development. With the continuous progress of technology and the increase of market demand, it is believed that inorganic salt wastewater treatment equipment will achieve more significant results in the future development.
