water chemistry analysis
Principles of complex water chemistry.
Wastewater treatment operators operate equipment used in a water or wastewater plant. They treat and clean drinking water before it is distributed to the consumer and process wastewater to remove harmful substances before returning it to rivers and seas. They take samples and perform tests to analyse the water quality.
