Polyaluminum chloride is mainly used in drinking water treatment, industrial water supply and drainage treatment, industrial wastewater treatment, industrial circulating water treatment and urban sewage purification treatment, drinking water treatment, food industry water treatment, pharmaceutical industry water treatment, mining wastewater treatment, electroplating Factory water treatment, slaughterhouse wastewater treatment, farm wastewater treatment, all industries that use water can cover more than 90%.
Polyaluminum chloride is divided into industrial grade polyaluminum chloride, drinking water grade polyaluminum chloride, high-purity polyaluminum chloride (white polyaluminum), basic aluminum chloride and polyaluminum ferric chloride.
Polyaluminum chloride can be divided into: 20 general goods, 22 content, 24 content, 26 content, 28 content, and 30 content in terms of content.
Polyaluminum chloride can be divided into: liquid polyaluminum chloride, granular polyaluminum chloride, powder polyaluminum chloride according to the shape. Polyaluminum chloride can be divided into: tan polyaluminum chloride, millet yellow polyaluminum chloride, white polyaluminum chloride according to color.
How to use polyaluminum chloride: use it in small quantities first and then use it in large quantities.
1): dissolve the polyaluminum chloride agent into a 5% aqueous solution;
2): Take a 1000ml beaker, inject 1000m of water sample to be treated, add 0.2m of 15% PAC solution dropwise with a graduated dropper, stir evenly, stop stirring, and observe whether the supernatant is turbid after the floc has settled. , if it is cloudy, continue to add an appropriate amount of 5% PAC solution, stir evenly, and observe the supernatant after standing. If it is still cloudy, continue to add PAC until the supernatant is clear, and record the total volume of PAC liquid consumed.
Calculate:
Pharmacy usage = (total volume of consumed medicament, concentration of XPAC solution 5%)/volume of water sample
