Evaluation of various hydroponic techniques as decentralised wastewater treatment and reuse systems

Abstract

A hydroponic system as decentralised wastewater treatment and reuse was tested. The hydroponic system was built in a greenhouse in order to improve growth conditions for plants including orchard trees, vegetables and flowers. The experiment was conducted from 2007 until present, in a model greenhouse which was installed at An-Najah National University’s new campus, in hydroponic barrels and channels filled with soilless-media. Findings showed that the hydroponic system is effective in reducing various pollution loads. The performance of hydroponic barrels was better than the channels, and winter squash and trees were better than flowers and vegetables.
