Wastewater system contain Phospho total very high.
Level B of wasewater according with standard: P is 6 mg/l.
But the factory used STPP very much. So, Phospho total is very high to 200 mg/l.
We had invited many wastewater company treatment to find measures but not to search results because Wastewater system contain Phospho total very high so the cost very high.
To P reduce, what do we do?
Thanks
