Such as, In case the COD level in the effluent is bigger than expected, it might indicate that the remedy processes will not be Operating correctly. In this instance, the operator might want to adjust the therapy procedure parameters or investigate opportunity problems with the therapy tools.
Soon after becoming positioned in a very sedimentation tank for excess remedy just before disposal, flocs undertake sedimentation while in the wastewater treatment method approach.
It really is applied to deliver an indication of the level of pollution in the drinking water class, Particularly after a drinking water treatment method process.
The level of potassium dichromate Utilized in the response is similar to the amount of oxygen (O2) necessary to oxidise the wastewater’s organic information.
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:
