How to recover phosphoric acid from chemical polishing during anodic oxidation of aluminum alloy? Strive to achieve zero pollution, full recycling, environmental protection, benefit the country and the people! ? I wonder if the landlord is a big company? Such a waste, phosphoric acid and emissions!

Go to some small workshops to learn from your experience. Generally, the chemical waste in small factories is reduced by evaporation and take-away. You can hardly see it. Build a new bath.

If you change it every six months, you should not recycle that little thing.

The final solution is: treat the company's money spent on phosphoric acid as its own money, so it won't be discharged at will. Adjusting waste is a technical problem, not to mention that small factories have low requirements for products, but they really have low requirements for real big brands.
