Hi Stabilization ponds, or lagoons, or waste stabilization ponds use a natural process for wastewater treatment that has a combination of macro plants, substrates and microorganisms in a +/- artificial pond to treat wastewater.
Stabilized waste is a waste product which has a low degradable potential leading to gas generation. In wastewater applications, sludge is usually stabilized through biological treatment (e.g. digestion). In landfill application, acceptance criteria is based on a biological respiration rate measured by simple lab test. Biological respiration rate is directly proportional to bio-degradable organic content of the stabilized waste. Target respiration rate and testing method varies amongst countries ( i.e. Germany <5mg O2/g dry mass/96 hrs (Static Method), Italy <10mg O2/g dry mass/96 hrs (Dynamic Method))
A waste that has been treated or decomposed to the extent that, if discharged or released, it's rate and state of decomposition would be such that the waste would not cause a nuisance or odors in the receiving water.
