Before cleansed wastewater is discharged into a stream, creek, river or the sea it must be ensured that local legislation is fulfilled with regards to the wastewater outlet specifications. In the EU countries, each wastewater treatment plant is obliged to take samples of the discharged wastewater up to 5 times per day in order to document the content of harmful substances. If the discharge values are exceeded, the wastewater utility is obliged to pay a fine. Of course, this increases the motivation to clean the wastewater effectively in order to meet the EU discharge requirements of wastewater outlets.
For wastewater outlet, AVK offers gate valves, butterfly valves, knife gate valves, penstocks, check valves, couplings, adaptors, fittings, and accessories.
