Engine Emission

As the increasingly strict emission regulations, develop new and efficient desulfurization equipment, to meet the requirements of future Marine sulfur emissions control, ensure freedom of navigation in all waters of the ship, we need to desulfurization of diesel engine emissions. Waste desulfurization generated also need to process and strict inspection to reach the discharge standard of corresponding IMO. The main purpose of this paper is to study a new system for processing waste engine emission for marine diesel engine, this system will make waste liquid treatment becomes more efficient, energy saving, but also saves the cost of waste water treatment. This paper introduces a new technology for processing ship washing desulfurization waste liquid, we analyze the advantages and disadvantages of this equipment. Finally, this method gives the improving measures for the problems and prospects for the development trend of ship desulfurization wastewater treatment.

Polymer Formation

In waste water treatment processes microorganisms are subjected to a feast and famine regime. For sequencing batch processes this is often even more pronounced. Based on literature reports and own research it is hypothesized that in general microorganisms respond to these feast-famine regimes by accumulating storage polymers (polyhydroxyalkanoates) when substrate is present. The storage polymers are used for growth when the external substrate is depleted. In this manner the organisms are capable to balance their growth. A general hypothesis explaining polymer formation is developed. The advantages and disadvantages of this formation of storage polymers for the operation of SBR processes is discussed.
