Whether polyferric sulfate can be used with bleaching water

Many people will wonder whether polyferric sulfate can be used with bleaching water, so bleaching water can play a disinfection and sterilization effect. Therefore, after the wastewater is treated with polyferric sulfate, whether bleaching water can be used for disinfection and sterilization. Therefore, the following section will introduce to you whether poly iron can be used together with bleach.

Most wastewater treatment chemicals cannot be mixed. In addition to the neutralization reaction due to the difference of the original acidity and alkalinity, other oxidation-reduction reactions can also occur, which change the properties of two different substances. For example, when polymerized polymerized ferric sulfate is mixed with bleaching water, ferric sulfate and polyaluminum chloride are mixed, hydroxide colloid will be formed, which will lose the polymerization and greatly weaken the coagulation effect. When bleaching water and polyferric chloride are mixed, chemical reaction will also occur. When they are used in wastewater coagulation treatment, the sludge formed will be oxidized and dispersed due to the oxidation of bleaching powder, and the flocculation effect will not be achieved.

Dosing sequence of polyferric sulfate and bleaching water

In normal wastewater treatment, coagulants such as polyferric sulfate, aluminum sulfate and ferrous sulfate will be added in the pretreatment tank or secondary sedimentation tank for coagulation treatment to treat the suspended particles in the water. At the same time, some microorganisms and fine bacteria attached to the sludge or suspended solids in the water can be removed together. Reduce the attachment of bacteria and bacteria, and the resistance of bleaching powder wastewater treatment, and improve the treatment effect.

As a disinfectant, bleach water is mostly used in secondary sedimentation tanks such as disinfection tanks to further disinfect the effluent from secondary sedimentation tanks or biochemical effluent, so that residual toxic and harmful bacteria in the water can be sterilized.

Therefore, in general, PFS can be used together with bleach, but you must pay attention to the order in which it is put, otherwise it will cause various problems once the wrong order is used.
