An expansion of the existing plant is required for this work.

The subject project concerns an additional purification step at the RWZI Amstelveen that achieves an improvement in the water quality of the Amstel through better effluent quality. To achieve this, the technical objectives for the entire purification process, including the expansion, are as follows: [newline]- removal of micropollutants of at least 80% relative to the wastewater entering the RWZI (for the subsidy from the Ministry of Infrastructure and Water Management, a purification performance of at least 80% applies); [newline]- extensive nutrient removal relative to the current effluent

Which standards apply to the nutrient removal (phosphorus and nitrogen)?
The effluent may not contain more than 0.25 milligrams of phosphorus per liter of wastewater (based on a moving annual average). The effluent concentration of nitrogen may not exceed 5 milligrams per liter of wastewater (over a moving annual average).
What requirement is set for the disinfection step?
A disinfection step must be realized up to 1,800 cfu E.coli/dl to promote the swimming water quality in the Amstel.
