Agricultural and Food Processing Wastewater Testing

Wastewater is the most serious environmental problem in the manufacturing and processing of foods. If inadequately treated wastewater were to be discharged to a stream or river, a eutrophic condition would develop within the aquatic environment due to the discharge of biodegradable, oxygen-consuming materials. If this condition were sustained for an extended period of time, the ecological balance of the receiving stream, river, or lake (i.e., aquatic microflora, plants, and animals) would be upset. The waste-waters produced in agricultural manufacturing processing and food processing vary in quantity and quality. A clear understanding of the characteristics of food and agricultural wastewater permits management decision on treatment and utilization methods that are effective and economical.

STEMart can carry out comprehensive testing on physico-chemical and biological parameters of wastewaters generated from the fishery industry, dairy industry, fruit and vegetable processing, meat and poultry processing, oil and fat processing, etc.
