The wastewater was highly contaminated with amines and phenols (COD up to 5000mg/l). The facility used a batch processing method, which meant the water was highly variable, and very difficult to treat by conventional methods. Starting with demonstration that soil based reed beds were the ideal solution as they were versatile enough to handle the

An old industrial site that had been used as a pesticide research and development facility required remediation. The ground and underlying aquifer was heavily contaminated with pesticides and other chemicals. Initially the contaminated soils were removed and partially treated by thermal desorption. Next, a groundwater treatment system was installed. This consisted of 4 reed beds
