When the filter press treats acidic sewage, everyone has to consider the possible corrosion problems. How to avoid corrosion and possible adverse effects? The people of Sudong Chemical gave some suggestions:
1. Use alkaline filter cloth. Change the filter cloth of the filter press to alkaline, so that the acid filtrate can be neutralized;
2. Dilute the filtrate. Before pouring the filtrate into the filter press for processing, we can dilute the filtrate to a certain extent, and also reduce the acidic content of the filtrate;
3. The use of alkaline reagents to neutralize the filtrate without affecting the quality of the filtrate can also reduce the corrosion of the filter press by the filtrate.
When the filter press is used to treat the too acidic sewage, the above measures can be taken to avoid the corrosion phenomenon of the filter chamber, and will not have a bad influence on the final effect of sewage treatment.
