Is it necessary to use polymeric aluminium chloride flocculant to treat chemical wastewater?

Is it necessary to use Polymeric Aluminium Chloride(PAC) flocculant to treat chemical wastewater?

The wastewater from chemical plants mainly comes from consumer wastewater discharged from the petrochemical industry, coal chemical industry, acid-base industry, fertilizer industry, plastic industry, pharmaceutical industry, dye industry, rubber industry, etc.

If the wastewater from chemical plants is not properly treated, it will cause significant pollution to the environment and pose a threat to human health. Therefore, when dealing with wastewater from chemical plants, YuXinHuan chemical polyaluminum chloride and other water purification agents can be the first choice for managing environmental pollution.

Polyacrylamide PAM , polyaluminum chloride PAC , caustic soda, ferrous sulfate and other wastewater treatment agents are used in the process of wastewater treatment in chemical plants.

In the selection of flocculants, industrial grade Polyaluminum Chloride PAC and cationic Polyacrylamide PAM are commonly used as sludge dewatering agents, while anionic polyacrylamide is used as sewage settling flocculant.

The main measures for the treatment and prevention of wastewater in chemical plants are:

Firstly, consumer processes and equipment should be reformed to reduce pollutants, avoid wastewater discharge, and stop comprehensive application and recycling; The disposal level of wastewater that needs to be discharged should be selected based on water quality and *ments. The primary disposal mainly separates suspended solids, colloids, floating oil or heavy oil in water. Methods such as water quality and quantity regulation, natural sedimentation, floating, and oil separation can be used. Secondary disposal mainly involves removing biodegradable organic dissolved substances and local colloids, reducing the biochemical and local chemical oxygen demand in wastewater, and usually using biological methods for disposal.

After biological treatment, there is still a considerable amount of COD remaining in the wastewater, sometimes with high color, smell, and taste, or due to high environmental hygiene standards, further purification is *d using a three-level disposal method. Third level disposal mainly involves removing organic pollutants and dissolved inorganic pollutants that are difficult to biodegrade from wastewater. Common methods include activated carbon adsorption and ozone oxidation, as well as ion exchange and membrane separation techniques. Various chemical industry wastewater can be treated according to different water quality, quantity, and *ments for discharged water quality after treatment, and different disposal methods can be selected.
