Economic Feasibility

The KOPF process allows for a sustainable valorisation of sewage sludge, which makes sense also from the viewpoint of economics. Even the last step in the process chain of sewage disposal is done at the sewage works, as sewage sludge is being valorised energetically and materially. Material and energy flows form closed circular processes. The mineral granulate as solid end product of waste water cleaning becomes a commodity. Heat and electricity from gasification and heat-power station come available at the sewage works and need not be purchased from external suppliers. The vision of a sewage works which is autarchic for energy and disposal becomes reality. The total cost of disposal is lower than with other thermal ways of disposal, such as, for example, co-combustion in a waste incineration plant. Due to the independence of external utility providers a cost efficient disposal is permanently secured.

Process

The key component of the KOPF gasification process is the gasification reactor, where in a stationary fluidised bed at temperatures up to 900Â°C combustible gas is produced from dried sewage sludge. In the raw gas quench, it is cooled down and subsequently it is worked up further by filtering and drying. In a block type heat-power system, it used to produce electricity and heat. After a retention time of 30 minutes, the sewage sludge has been reduced to an inert granule. It has a high content of valuable phosphorus, which can be extracted with new processes, as a main ingredient of fertilizers. What remains is an inert mineral granulate, which offers a variety of application possibilities such as, for example, the making of asphalt or as filler material in street building and landscaping.

System solution

At the end of the process chain, volume has been reduced and a valuable product has come available For the decentralised energetical and material valorisation of sewage sludge, operators of medium sized sewage works now have a convincing option being the KOPF gasification process. The patented process turns sewage sludge into energy and a valuable product and degrades the characteristic freight of pollutants. Economical feasibility is given for plants as small as 1000 tonnes sewage sludge dry matter per year, which corresponds with 50,000 inhabitant-equivalents. Up scaled variants of the process up to fourfold throughput are feasible without any restriction.
