Mono incineration sludge.1648960778

Currently, a mono-incineration plant is in the process of being authorized for the disposal of sewage sludge. It will have a capacity of 3 t/h and generate quality ash that is rich in phosphorus and low in pollutants, which facilitates processing into fertilizer. The company, WEHRLE-WERK AG, located in Emmendingen, specializes in Energy Technology. Ruckert NatUrgas GmbH, a subsidiary of the Ruckert Group, is currently processing sludge at its plant in Lauf a. d. Pegnitz.
The plant in the Netherlands processes approximately 1,500 tons of sludge daily. Incoming sludge is deposited into a bunker in layers. Buckets are then used to collect several layers of sludge and transport it to a fluidized bed incinerator. Of the dry sludge, 62% is comprised of combustible organic matter. The rest is ash. The ash is used for asphalt production and in a salt mine in Germany.

Sludge used for mono-incineration is a biofuel, with a high solids content. This biomass waste is a source of biomass, and ash can be obtained from the process. The process is environmentally friendly and produces electricity for local residents. However, the use of sludge as a fertiliser is regulated by national legislation. The EU Directive 86/278 regulates the use of sludge for agriculture and has strict regulations in member states.

The process is completely safe for humans and the environment. The plant also includes a highly efficient flue gas cleaning system and an S2E-Fluidizer, a stationary fluidised bed furnace with fuel heat capacity of 14 MW. The facility is fully self-sufficient and will generate the highest amount of energy from sewage sludge. The resulting ash will be used to produce environmentally friendly thermal and electrical energy.

During the incinerating process, the sludge is conveyed via the fuel transporting system. The feed-buffer is located in the incinerator’s bunker hall and is equipped with a discharge screw. The sludge is separated from the fuel transporting system by a sliding frame and a discharging screw. The ash is dewatered and dried in the incinerator.

When the sludge is being incinerated, the waste water generated during the process is highly polluted. The water from the incineration process contains volatile organic materials and ammonia. These pollutants are also present in the residuals of the incineration process. It is important to make sure that the incineration process is performed as efficiently as possible to prevent pollution. Aiming for environmental benefits, the Mono incineration plant will also improve the efficiency of the entire plant.

Another thermal sewage sludge treatment facility, the Outotec Plant in Straubing, Germany, has been built by sludge2energy GmbH as a general contractor. The project partners include the city’s municipal sludge street-cleaning company, the Biomasseverwertung Straubing GmbH, and Bayernwerk Natur. These are three major companies that are responsible for the construction and operation of the mono-incineration sludge plant.

The benefits of this project are both social and environmental. By using an incineration plant, the sludge is burned exclusively. As a result, the energy required for the process is recovered. The plant also helps in the circular economy by allowing for the recycling of phosphorus and other organic waste. It is not a complete solution to the problem of sludge disposal, but it is an important first step.

In Switzerland, an incinerator processes 20,000 tons of sludge annually. About 12.5% of the sludge is co-combusted with the waste, which has a heating value of 13 MJ/kg. The incineration of sludge has a significant impact on the energy balance of the process. The company is energy-positive, but sludge has a negative effect on its NOx emissions.

One mono-incineration facility, Hong Kong T-park, uses four fluidized bed incinerators with a maximum power output of 14 MW. It processes about 2,000 tons of dewatered sludge daily. During combustion, the sludge is reduced to ashes and the ash is sent to a landfill. The facilities are integrated with water desalination plants, power generation facilities, and educational recreation centers. The heat and electricity produced on site help support the entire facility.
