Process Control requires correct interpretation of Control Parameters
It is a well established fact that information relating to key control parameters is essential to optimize wastewater treatment plant performance. In our experience it is all too common for problems to arise where information is either not generated or, more times than not, not reviewed or interpreted correctly. #ecos saves businesses a lot of...
READ ARTICLE >Wastewater: Activated Sludge – Microscopic examination
Quite often businesss could save themselves a lot of time and money through recording and reviewing key control parameters on a regular basis. The establishment of target and optimum ranges for key control parameters can assist in forecasting when non-compliances could arise and allow for suitable remedial measures to be implemented before a problem develops....
READ ARTICLE >Wastewater Nitrification: How it works
Nitrification is the sequential conversion of ammonia to nitrite and ultimately nitrate: NH4+ + 1.5 O2 → NO2– + H2O + 2H+ Ammonia in wastewater could originate from a variety of sources, including: Proteins (meat and blood), urea, amino acid products, casein, corrosion inhibitors, process chemicals and raw materials or cleaning chemicals containing quaternary ammonium compounds....
READ ARTICLE >Wastewater: Activated Sludge – Biological Foaming
Biological foam is due to operating conditions in the wastewater treatment plant. It accumulates on the surface of the aeration basin and may carry over into the final clarifier and effluent discharge. The use of detergents also generates foam but the comments below relate solely to biological (bacterial) foams. Three types of biological foaming may...
READ ARTICLE >Wastewater: Activated Sludge – Key Control Parameters can save a lot of time and money
How often has been found that insufficient data has been available relating to key control parameters of wastewater treatment operation and performance? Unfortunately the answer is “way too often”. Many business could save themselves a lot of time and money through recording and reviewing key control parameters on a regular basis. The establishment of target and...
