The principle of purchasing iron-free aluminium sulfate

Iron-free aluminium sulfate can be widely used in papermaking, as well as for sewage treatment, and can also be used for the purification of drinking water. Given its significant role in use, if the quality of the selected product is not good, it is likely to lead to adverse effects or even negative impacts when using it. Therefore, it is very important to choose a better product when purchasing. Let's take a detailed look at the purchasing principles of the product.
1. Check the coagulation situation: under specific raw water quality, treated water quality requirements, and specific treatment process conditions, coagulation can have a better effect.
2. Sufficient supply: conduct corresponding research and investigation on the source of selected products and manufacturers. It is necessary to confirm the sufficient supply of iron-free aluminium sulfate, whether it can be supplied stably for a long time, and whether the product quality is guaranteed.
3. Health licence for new drugs: for new drug varieties that have not yet been promoted and applied, it is necessary to obtain permission from the local health department.
4. When used to treat drinking water, the selected products must not contain ingredients harmful to human health; even if the product is used for industrial production, the chosen product should ensure that it does not adversely affect industrial production.
5. Low cost: when there are various products with similar quality and sufficient supply, it is necessary to comprehensively consider the price of the drug, the cost of transportation, and the amount of dosage, etc., to analyse the cost performance, and reduce the cost of use as much as possible while ensuring that the water quality after treatment is good, and to purchase with relatively high cost performance.
