Problems solved by technology

[0002] Flocculation technology is a very mature technology for water treatment. There are many products such as inorganic flocculants, organic flocculants, and microbial flocculants with different functions. At present, flocculants and related technologies are used in open waters such as rivers, lakes, and reservoirs. It can be said that there are only a handful of companies with the main line of technology. As a rapid water treatment technology, flocculation technology has its irreplaceable technical advantages and treatment effects. Many domestic research institutes or companies are carrying out related technology research and development and engineering practice. The high-efficiency, non-toxic and harmless flocculant is the basic trend of the developm
