On the treatment of phosphate wastewater
Thread Content
Our company used to handle phosphorus-containing wastewater, which was in the form of phosphoric acid. The client used this substance for rust removal; the product was taken out of the phosphoric acid tank and then rinsed, and the wastewater resulting from this process contained phosphoric acid. Now, no matter whether I add lime, ferric chloride, or phosphorus removal agents, or even use activated carbon for adsorption, the total phosphorus content in the water remains above 50 mg/L, and sometimes it even exceeds 100 mg/L. The environmental protection authorities are also keeping a close eye on this issue. I’m at a loss now and hope that those of you here can share your opinions and suggestions. Thank you!
You can try phosphorus-removing resins; we have used them before. If needed, we can discuss it and arrange experiments
Phosphorus removal in seawater, phosphorus release in fresh water – it’s possible to reduce levels from 300-400 ppm to 1 ppm
If a further increase in the phosphate removal rate is desired, ion exchange resins can be used to ensure compliance with discharge standards at the end of the process; the high-concentration phosphorus-containing wastewater resulting from the regeneration of these resins can then be sent back for pre-treatment. We specialize in resins, and I personally believe that using high-quality anhydrous resins can solve the problem. We can provide relevant pilot tests here; if needed, please contact 18969098391@163.com
