Polyaluminum chloride manufacturers concerned about softened water equipment, demineralized water equipment as an important factor in industrial water treatment, including aluminum chloride is an indispensable factor General classification of demineralized water equipment can be divided into industrial water treatment equipment, drinking water treatment equipment, irrigation Equipped with equipment, water treatment accessories several categories. Recently, the Ministry of Housing and Urban-Rural Development was informed that as the technology of demineralized water equipment has become a key technology of water treatment equipment, the size of urban sewage treatment in our country has doubled during the "Eleventh Five-year Plan" period, basically equal to that of softened water equipment in the United States. Become one of the largest water treatment equipment in the world. The invention of demineralized water equipment technology is only over 50 years old, and the industrialized application of demineralized water equipment technology is more than 20 years old, and the actual commercial application in our country is only over ten years. At present, China has a number of technical application of technology development and specialized water treatment equipment companies, such as China National Bluestar Environmental Engineering Corporation, Xiamen Waibang company, has an independent research and development capabilities of water treatment equipment technology and talent, In softened water equipment technology application development has a strong strength, and some have become softened water equipment technology research and development, design, construction, installation and commissioning, operation and management in one of the specialized membrane technology company.
