The reduction is achieved through removal of the carbon upstream of the biological treatment stage of the wastewater treatment plant, e.g. by building a preliminary settling tank or installing a HUBER fine screening system. Due to continuously increasing energy costs, changing from an aerobic to an anaerobic process frequently makes sense for sewage treatment plants for economic reasons.

Carbon Dioxide (CO2), which is an inevitable product of burning a fuel which contains carbon (as all petroleum products do). CO2 does not pollute the air we breathe, but it is a main contributor to Global Warming and therefore has to be reduced. This means either using fuels containing less (or no) carbon (see the section on Alternative Fuels), or making vehicles and their engines more efficient – or both.

However, unburnt carbon in the fly ash adversely affects the fresh properties of concrete. For this reason, when fly ash having a high unburnt carbon content is used as an admixture for concrete, it is desired to reduce the amount of unburnt carbon. So far, at our university, we have developed a technique to remove unburnt carbon by flotation method. It is necessary to add a scavenger and a ...
