Principle of polyacrylamide treating sewage
Polyacrylamide is mainly used to treat sewage, domestic sewage and industrial sewage can be used. When used to treat sewage, polyacrylamide usually adopts two methods. Today, we will briefly explain the two methods of Polyacrylamide in sewage treatment.
The physical treatment method of polyacrylamide wastewater treatment: the wastewater treatment method of separating and recovering the insoluble and suspended pollutants in wastewater by physical action. Precipitation, filtration, centrifugal separation, air flotation, evaporation crystallization and reverse osmosis are usually used. The pollutants such as suspended solids, colloids and oil are separated from the wastewater, so that the wastewater can be preliminarily purified.
The second is the chemical treatment method in polyacrylamide wastewater treatment: through chemical reaction and mass transfer to separate and remove the dissolved and colloidal pollutants in wastewater or convert them into harmless substances. The commonly used methods are neutralization, coagulation, redox, extraction, stripping, stripping, adsorption, ion exchange and electroosmosis.
Polyacrylamide in the treatment of sewage, are generally used these two methods, often using polyacrylamide related technical personnel, must be familiar with these two methods, so as to be able to better application.

Is sewage treatment agent dangerous?
With the continuous strengthening of China's efforts, the application range of sewage treatment agent is gradually extensive, greatly reducing the severity of environmental pollution, so this is a dangerous goods? The following sewage treatment agent manufacturers to do a detailed explanation for you: does sewage treatment agent belong to dangerous goods? There are many kinds of sewage treatment agents on the market, but all the treatment agents are chemicals. If you drink and eat them by mistak
