Solid wave motion in maritime coastal places may perhaps assure aeration, whereas Mild wave action and riffles might or might not be enough, with regards to the depth on the water and rigor of mixing. Screening in these conditions need to be complemented with steps of DO concentrations (see Ways to Measure tab).
Very careful checking of COD, and then next up with BOD tests can permit for proactive corrections towards the wastewater treatment. Many times, COD testing can be a necessity for wastewater therapy vegetation; which testing all causes time and value financial savings for that vegetation.
Environmental analyzers are subtle scientific devices utilised in modern day COD testing processes.
