This allows improve the In general environmental overall performance of industries and minimize their influence on drinking water methods.

This process is comparable to the dichromate strategy but works by using potassium permanganate as opposed to potassium dichromate. It's got the advantage of being able to differentiate amongst biologically available and inert organic make a difference, but it is much less correct and much more time-consuming compared to the dichromate process.

Wastewater generated by business, industrial and institutional facilities is typically called "large-strength" in comparison with typical house wastewater.

Do có nồng độ cao trong phần lớn các loại nước thải nên chloride thông thường là nguồn quan trọng nhất trong việc gây nhiễu. Phản ứng của nó với dicromat kali như sau:
