In the anaerobic process the pond which is usually 2.5 to 4.5meters in depth, is loaded with heavy organic influent and there is no aerobic zone. After adetention period of five to fifty days bacterial acid and methane fermentation processes are usedto break down the waste. The facultative process is vital in the design of the wastewatertreatment process which is used in the treatment of raw waste from the municipal in smallcommunities (Henze et al., 37). The other principle which is equally important is the aerobicprocess. This process is used in the breakdown of waste through the formation of algae and thenormal photosynthesis process by maintaining algae on the surface and allowing light andoxygen to penetrate.Question 2The primary causes of air pollutants which are linked to the global warming effect are; carbonmonoxide, lead, nitrogen dioxide, ozone, particles and sulfur oxides. Carbon monoxide isproduced by incomplete combustion of the carbon-containing fuels like gasoline. Vehicleemissions are also a significant cause of the carbon emissions. Lead is generated into the air inthe form of suspended particles. Industrial sources are a significant source of lead in theenvironment (Schulze, 779). Nitrogen dioxide is one of the air pollutant produced as a result ofSurname 2t ...
