This process is unique in photosynthetic carbon sequestration. An on-site biological sequestration system directly decreases the concentration of carbon-containing compounds in the emissions of fossil generation units. In this process, photosynthetic microbes are attached to a growth surface arranged in a containment chamber that is lit by solar photons. A harvesting system ensures maximum organism growth and rate of CO2 uptake. Soluble carbon and nitrogen concentrations delivered to the cyanobacteria are enhanced, further increasing growth rate and carbon utilization.

Provided are a filter assembly for a dishwasher and a dishwasher having the same. In the filter assembly for the dishwasher and the dishwasher having the same, since a cylindrical filter unit is formed through a plate filter unit, the entire area of an inside of a filter frame can be implemented as a filtering area where foreign materials contained in water circulating toward dishes to be washed up are filtered off. Accordingly, the extended filtering area can increase an amount of water supplied onto the dishes, thus to enhance an efficiency of water circulation. Also, a possibility that a filter is blocked due to foreign materials covering all over the filtering area can remarkably be reduced. Since the cylindrical filter unit is formed through the plate filter unit, the entire size of the filter assembly can be decreased with maintaining the filtering area of the filter assembly. Hence, no great installation space for a compact dishwasher is required, thereby facilitating the installation of the dishwasher.
