The most reliable and thorough analysis of polyaluminum chloride, an inorganic polymer coagulant, reveals that its molecular weight is enhanced through the bridging action of hydroxide ions and the polymerization of polyvalent anions. It is considered a highly charged inorganic polymer water treatment agent. Polyaluminum chloride comes in both liquid and solid forms. Liquid polyaluminum chloride, which hasn't been dried, offers the benefits of no dilution needed, easy loading and unloading, and a relatively low price. However, it requires tanker transport, which can increase the unit transportation cost (equivalent to 2-3 tons of liquid per ton of solid). The solid form, after drying, is easier to transport without needing a tanker. The downside is that it needs to be diluted before use, increasing the workload.
Performance-wise, polyaluminum chloride outperforms aluminum sulfate in terms of water purification quality, reducing costs by 15-30%. Its flocs form quickly, settle faster, and handle larger volumes compared to traditional products like aluminum sulfate. The treated water's alkalinity is lower than other inorganic flocculants, meaning less alkali needs to be added. It works well in source water with a pH range of 5.0-9.0, has low corrosiveness, and dissolves better than aluminum sulfate. Additionally, it introduces less salt into the treated water, making it suitable for ion exchange treatments and high-purity water production. Its adaptability to varying water temperatures surpasses that of inorganic flocculants like aluminum sulfate.
The recommended dosage varies depending on the water quality. For instance, when dealing with turbidity levels between 100-500 mg/L in normal temperature water, the dosage typically ranges from 3-6 mg/L. A small-scale test should always be conducted to determine the optimal amount.
Packaging-wise, polyaluminum chloride is typically sold in 25 kg plastic bags with an inner plastic film. Customizations are possible based on user requests. Liquid polyaluminum chloride is also available. It’s crucial to store this product away from toxic substances, keeping it in a dry, well-ventilated, and cool indoor environment to prevent moisture damage.
When using polyaluminum chloride, start with a small trial based on water quality to find the optimal balance of effectiveness and dosage. Always use solutions immediately after preparation. For solid forms, dissolve them in water to create a 10-25% solution, then dilute it further to the desired concentration. Slowly add water and continuously stir during dissolution. Mixing products from different manufacturers or brands isn’t recommended, nor is combining them with other chemicals. Stock solutions and dilutions are mildly corrosive but less so than other inorganic flocculants. The product remains effective for up to six months for liquids and two years for solids, which can still be used even if they absorb some moisture.
After proper application, the treated water meets drinking water hygiene standards. Manufacturer Address: Polyaluminum Chloride http://
