Evaluation of Treatment Processes for Greenhouse Wastewater Streams

The greenhouse industry constantly strives for innovative solutions to reduce production costs and environmental footprint. Greenhouses commonly generate process water including nutrient feedwater and other non-production wastewater. They also use fertigation, a soil-less drip irrigation method that requires large quantities of water and nutrients. Due to sharp reduction of available phosphorus (P), P recovery from wastewater streams is an economic opportunity.
