PPT-Summary of the water treatment media and their use

Dirck Demeyer 1 1 Basic data Important knowledge In most cases of problem report the cause is to be found is the wrong choice of equipment wrong medium the hart of the installation. In the biological treatment of wastewaters aeration is essential to raise the dissolved oxygen DO level to allow aerobic bacteria to work and reduce the pollution load BOD of the waste and thus to improve water quality The rate of oxygen transfer in Results of the SILEN-C3 trial.
