Chemical Waste Treatment Pilot

Most mineral chemical waste produced by industry (or during practical work sessions) consists of more or less concentrated aqueous solutions that may contain various chemical species (acids, bases, oxidants, reducers, heavy metal compounds, etc. ).

The primary objective of treating this waste is to recover, on one hand, the polluting chemical species as precipitates, and on the other, an aqueous phase containing only very low or non-polluting chemical species. The precipitates (sludge) containing the polluting species can then be entrusted to a specialized company, and the aqueous phase (pH adjusted between 5.
