Water pollution has become significantly more severe. Although the state is vigorously promoting water source protection, the results remain largely ineffective. Consequently, an increasing number of enterprises are addressing wastewater contamination by adding water purification agents to the water. Once these chemical agents are introduced, many begin to express concern: could these substances pose a threat to human health?
Among all water purification agents, polyaluminium chloride (PAC) products are particularly well-known for their rapid efficacy in treating wastewater. Does PAC pose health risks? The answer is unequivocally no. The purification process involves multiple stages of sedimentation and filtration, which virtually eliminate residual PAC compounds. This poses no threat to human health. However, for those with lingering concerns, advanced equipment can be employed to detect residual traces of polyaluminium chloride during water purification. This ensures residual levels are minimised or even eliminated.
Additionally, during water treatment with VICTOR polyaluminium chloride products, another substance involved is nitrogen dioxide. Nitrogen dioxide is a relatively safe disinfectant. It possesses strong bactericidal properties and does not pose harm to humans or the environment. It does not produce carcinogens. Consequently, it is frequently utilised in food preservation and deodorisation.
However, it should be noted that suspended solids may still appear during water purification with
polyaluminium chloride products. This may stem from insufficient product specifications or incorrect dosage. Moreover, the quality of polyaluminium chloride products available on the market varies considerably, with significant price discrepancies. It is therefore advisable to select a higher-quality polyaluminium chloride product. Premium polyaluminium chloride products contain virtually no insoluble matter, meaning no suspended solids. When purchasing polyaluminium chloride products, it is recommended to compare offerings from multiple suppliers to select the most suitable option. Typically, preliminary testing is advisable. During experimentation, flocculated particles should precipitate. Larger particles settle rapidly, while smaller ones may exhibit suspension. In such instances, combining the product with polyacrylamide can effectively prevent suspended matter. However, note that when using both polyaluminium chloride and polyacrylamide for water purification, the sequence of addition must be strictly observed.
