Wastewater Renovation by a Prototype Slow Infiltration Land Treatment System.
Abstract
The feasibility of a slow-infiltration land treatment system as an alternative to advanced waste treatment of wastewater was studied using six outdoor test cells. Wastewater was applied to forage grasses by spray irrigation. Parameters studied were wastewater application rate, effect of pretreatment and soil type and seasonal effects on the treatment system. Activated sludge pretreatment of the applied wastewater did not improve the overall quality of the product water from this slow-infiltration system. The uptake of nutrients by forage grasses accounted for significant removal of nitrogen and phosphorus from applied wastewater during the growing season. Other renovative mechanisms, namely nitrification/denitrification of applied nitrogen and phosphorus immobilization and fixation by the soils may have accounted for further renovation of the applied effluents.
