Use of the Carbo-Flo Process to Purify Process Water Contaminated by AgriculturalPesticides

摘要

The objective of the project is to reduce substantially contamination of surfacewater by pesticides as a result of the discharge of process water from the agricultural and horticultural sectors. The purification efficiency of the Carbo-Flo process has been studied in nine important agricultural and horticultural sectors. Chemical and toxicological analyses show that a high degree of purification is possible using the Carbo-Flo process. For the collection and storage of unused spray and washings, the infrastructure at farm level needs to be adapted. For large-scale introduction, processing plants with a capacity of 5-10 cubic meters per day are a good option from the point of view of treatment costs, licenses and quality control.
