Wastewater

Sewage treatment and wastewater analysis.

Virtual practicals

Simulated practicals with new data every attempt and a certificate for each one you pass. Results are simulated for learning.

Choose dilutions, read dissolved oxygen, check the depletion rules and calculate BOD for a wastewater sample.

Run blanks and samples, titrate excess dichromate with ferrous ammonium sulphate, and calculate COD.

Each tool shows the formula, a worked example and its limitations.
