Polyacrylamide(PAM) and Polyaluminium Chloride(PAC) are flocculants and coagulants commonly used in sewage treatment. The two are generally used together to achieve the effect of coagulation, flocculation and sedimentation. It is mostly used to deal with floating matter, impurities, pigments and other problems in printing and dyeing wastewater. It can be used for pre-processing at the front end of the process and in-depth processing at the back end of the process.
Sulfuric acid and sodium hydroxide: are two pH regulators commonly used in printing and dyeing wastewater treatment. They are used to adjust the pH of wastewater to ensure that sewage is treated and discharged within a suitable pH range. Other agents for treating conventional indicators are also used, such as oxidants, ferrous iron (reducing agent), etc.
Printing and dyeing wastewater treatment chemicals-environmentally friendly treatment chemicals:
Ammonia nitrogen remover: used to treat ammonia nitrogen in wastewater. It is used at the end of the process to decompose ammonia nitrogen through a strong oxidation reaction. It has the characteristics of fast reaction speed, wide adaptability, and no need to change the treatment process. It is especially suitable for medium and low concentrations. of ammonia nitrogen wastewater.
Phosphorus remover: The removal principle is to react with phosphorus in wastewater to generate insoluble substances, which are then precipitated to achieve the removal effect. It is a compound product of active metal salts, so there are also phosphorus removers of different concentrations and properties. It is mostly used to remove phosphorus-containing substances through sedimentation at the front end of the sedimentation tank.
