Saving chemicals and matching the aeration's outlet limits

Obtaining low ortho-phosphate outlet limits by controlling PO4 precipitation

The benefit of an online o-PO4 measurement is the opportunity to optimize the precipitation. Optimization means an increased safety to match the outlet limits even in case of major PO4-inlet changes. Secondly, a PO4 based precipitation control saves chemicals through avoidance of over dosage, reduces sludge production and improves the operational costs.
