We take 1 kmol of H 2 CO 3 as the simulated wastewater, and assume a theoretical reaction. Then, 62 kg of H 2 CO 3 will dissociate into 18 kg of water and 44 kg of CO 2. The percentage of water molecules recovered from such a dissociation process is 29.3%.
Webb1 dec. 2024 · Traditionally, wastewater cleanup technologies are classified as physical, chemical and biological methods for removing dyes and HMs from effluent. Physical and chemical have two major drawbacks: high cost and production of the significant amount of sludge that requires final disposal again [Chai et al., 2024, Paździor et al., 2024]. Webbsewage contains a particulate fraction which is inert or mineral. This fraction is simulated by diatomaceous earth, which helps to increase sludge floc density.
