Getting to grips with indirect discharges

Water authorities, environmental services and municipal authorities are increasingly seeing discharges of large quantities of chemical waste and other undesirable substances into the drains and therefore indirectly to surface water. That results…

The Ultimate Water Plant

The Ultimate Water Plant is a collaborative project involving parties in the water sector who want to demonstrate how, and subject to which conditions, treated sewage can be made available as a supplementary source of drinking water.…

Assuring WWTP effluent for greenhouse horticultural sector

The provision of irrigation water for the greenhouse horticultural sector is under increasing pressure, in part as a consequence of climate change. Alternatives are therefore being sought. Moreover,…

Pharmaceuticals from effluent

Wastewater contains increasing amounts of pharmaceutical residues. Since the WWTPs are not designed to remove them from the water, the plants’ effluent frequently still contains pharmaceuticals. Many techniques for the removal of these pharmaceuticals, and other micropollutants,…

Effluent reuse – Harnaschpolder

Technology The greenhouse horticultural sector in the Netherlands requires large quantities of high-quality irrigation water at an attractive rate. This project examined the possibilities of storing treated effluent in the subsurface, and then using it for greenhouse…

Effluent reuse – TOM Dinteloord

The successful realisation of the greenhouse horticulture area of Nieuw Prinsenland (Dinteloord) requires that the supply of irrigation water be made sustainable. There is insufficient rainwater to meet the needs of the greenhouse horticulturalists, and there are…
