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. This research will determine optimum treatment conditions for acidic condensate water from cogeneration process and will explore a combination of mineral sorbents and biological materials to intercept and capture P from greenhouse effluents. Washing out cannabis roots is an important process, which uses large amounts of water; yet there are no standards for its disposal. Properly treated wash water can be recycled back; therefore, wash water treatment will also be evaluated using media filtration and advanced oxidation processes such as ozonation, O3/H2O2 and UV.
