With the rapid advancement of industry, water pollution has become an increasingly severe issue, constantly affecting our physical health. It is important to note that contaminated water contains heavy metals, and drinking water may also exceed permissible heavy metal levels. Regular consumption of water with excessive heavy metals can cause harm to our health. So how can we remove heavy metals from water? Can the commonly used water purification agent,
polyaluminium chloride, achieve this? Let us explore this together.
Wastewater containing heavy metals manifests in diverse forms, necessitating varied treatment approaches and products. For instance, a deep blue hue in water indicates excessive copper levels. How should such wastewater be treated? The process begins by determining the wastewater's quality and suitable pH range, followed by adjustment within that range. This is then succeeded by sedimentation, filtration, and sludge treatment. Only after undergoing this series of processes can water meeting national discharge standards be produced. Poly Aluminium Chloride (PAC) is a high-molecular-weight inorganic flocculant. It demonstrates exceptional efficacy in purifying and treating both potable and industrial water, coupled with strong adaptability and broad applicability. It can be employed in diverse wastewater treatment scenarios. Particularly in modern industrial settings, heavy metals within discharged industrial wastewater pose increasingly severe environmental hazards. Untreated sewage containing heavy metals, if released into rivers or lakes, directly impacts fisheries and agriculture while also posing risks to human health. Consequently, industrial wastewater treatment must be approached with utmost diligence; arbitrary disposal is unacceptable.
How does polyaluminium chloride effectively remove heavy metals from water? The process primarily relies on chemical reactions between the agent and substances in the water. During dissolution, heavy metal salts in water are inert and may not readily react. A suitable product can achieve twice the result with half the effort. It may be stated that the addition of polyaluminium chloride not only removes heavy metals from wastewater but also causes no detrimental effects on water treatment equipment. Its efficacy is particularly pronounced in treating highly challenging effluents. It proves highly effective in eliminating turbidity, colouration, and various harmful substances from raw water, making it an invaluable asset in wastewater treatment.
