China's per capita resource-poor, ecological fragility, industrial waste water as the main factors of ecological environment pollution, received extensive attention of the public and country attaches great importance to. Especially put forward the construction of ecological civilization, the party's 18 put is famous for its ecological construction in prominent status, on the relationship between the people's well-being, concerns national future unprecedented heights, countries have formulated relevant laws and regulations in respect of water treatment, governing the industrial waste water discharge of unhealthy phenomenon. And specially not collect fees, without approval shall not be arbitrarily wastewater discharge of policy, objectively promoted the development of the flocculant production industry.

    Industrial wastewater using PAC treatment emissions must be implemented and the environment coordinated development of resources, resource saving and environmentally friendly sustainable developmental coagulant production development path.

    Coagulants for water purification agent by compressing double, adsorption mechanism, such as electric neutralization and adsorption bridging, sediment trap effect, make the tiny suspended particles in water and colloid ion stability, aggregation, flocculation, coagulation, precipitation, achieve purification treatment effect.

    Coagulant PAC flocculation body forming fast, good activity, good filterability, can overcome the difficulties of low temperature and low water treatment.

    Coagulant PAC production mode is divided into drum production and spray tower production in two ways, the content of drum production is divided into 26%, 28%, 30%, three, basically can reach more than 30% content of spray.

    With the constant improvement of coagulant production and technology of China, many wastewater treatment plants and waterworks using polyaluminium chloride water purification agent, after purification, the water quality fully meet the national standards, has obtained the good effect. Truly achieve the coordination of sustainable development with the environment.
