Bio-gas generation comprises comminuting and mixing untreated refuse with non-dehydrated clarifying sludge by a 2- or multi-step grinding process, pref using a 2- or multi- compartment ball mill. The sludge obtd is swelled for several hrs. All sludge components incapable of rotting, including plastics, are sepd by one or more flotation processes.
Generally, the acid wastewater is treated by lime-ferrate precipitation before discharged, with the generation of arsenic-containing gypsum sludge (GS) (Jing et al. 2003; Min et al. 2013). In addition, neutralization sludge (NS) also produces abundantly due to the treatment of comprehensive wastewater from copper smelter with lime precipitation.

Treatment Process for Wastewater. Before wastewater can be disposed of, it must undergo thorough treatment. This is true for any type of wastewater, including water supplies used in residential, commercial, and industrial settings. When wastewater is collected via sewers, it is delivered to plants for treatment and disposal.
Industrial wastewater treatment is required to remove contaminants and ensure that industries are fully compliant with regional industrial wastewater treatment standards. Wastewater treatment also helps companies save money by enabling the reuse of water in their industrial processes and minimizing waste processing costs.
