In the selection of sewage agents for customers, we generally have several reference values, such as the PH value of sewage, is acidic or alkaline ; sewage color is not high ; organic matter content in sewage and so on. The nature of sewage is very complex, the most accurate method is to do sewage treatment experiments. Recently, there are foreign customers consulting electroplating wastewater treatment polyacrylamide, let me give the recommended model. According to the practice and experimental data of Henan Xinhuan Water Treatment Materials Co., Ltd.for many years, if electroplating wastewater is mixed with other sewage,
cationic polyacrylamide is needed. If it is only electroplating wastewater,
anionic polyacrylamide can be used. Compared with anionic or nonionic polyacrylamide with the same molecular weight, cationic polyacrylamide is more expensive. Therefore, accurate selection can not only ensure the sewage treatment effect, but also save costs for enterprises. Electroplating wastewater generally belongs to strong acidic wastewater, which contains various heavy metal ions and cyanides. These substances are toxic substances, and random discharge will have a very bad impact on the environment. Electroplating wastewater is produced by cleaning water of plating parts, waste electroplating solution, equipment cooling water and other wastewater. At present, there are many ways to treat electroplating wastewater in China, and the common method is coagulation. In the process of treating electroplating wastewater by coagulation, polyacrylamide and polyaluminium chloride are needed. From the perspective of the working mechanism of flocculants, we mainly look at charge neutralization when selecting flocculants. Therefore, what we need to consider is the charge presented. Cationic polyacrylamide flocculant should be selected for flocculation of sewage or sludge with negative charge of suspended particles, otherwise anionic polyacrylamide should be selected.
Henan Xinhuan Water Treatment Materials Co., Ltd. is an excellent polyacrylamide manufacturer in China. The polyacrylamide produced by us is powdered and liquid, but the freight of liquid is relatively expensive. If users can bear high freight, they can also choose liquid polyacrylamide. If you need more technical parameters and quotations on polyacrylamide, please leave your mailbox and number and we will contact you.
The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade),
drinking grade polyaluminium chloride,
industrial grade polyaluminium chloride,
anionic polyacrylamide,
cationic polyacrylamide, nonionic polyacrylamide, petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
