Waste management is an ever concerning issue. More so now that the population of the world is increasing and the world’s urban centers are expanding exponentially. With this in mind, there is a need to develop and make use of waste management methods, processes, and technologies that not only reduce the effects of the waste we produce, but also turn it into a usable resources that can have a positive impact on our lives. Using sewage sludge carbonization machine is an effect way.
Sewage sludge carbonization plant technology fall under this category. The carbonization technology helps to convert waste in the form of sewage, into a usable resource – charcoal and carbon. This method is proving to be a popular option in as far sewage waste management is concerned. For the most part, the popularity of the technology has sharply owing to the benefits it yields to the entrepreneurs who invest in the plants as well as the environment.
Some of the sewage sludge carbonisation plant benefits include:
#1. Reduces The Amount Of Sewage Sludge That Ends Up In Landfill – The most important benefit of this plant is the amount of waste that does not end up landfill owing to its use. Traditionally, sewage sludge disposal involved burying the content in landfill and producing fertilizer with it. However, owing to the presence of the heavy metals, pathogens, and weed seeds, the use for fertilizer purposes has been limited.
On the other hand, sludge carbonization turns the waste into harmless products that do not need landfill disposal. Generally this is good for the environment.
#2. The Products Of The Plant Have Economic Value – Aside from reducing the amount of waste that ends up in landfills, the sludge carbonizing plant products have and economic value. The carbon and the charcoal can be sold. The carbon can be used as input in the production of products that use carbon and obviously the charcoal can be used as an energy source and alternative to mined coal.
#3. Offers A Better Way Of Separating The Heavy Metals And Organic Materials In Sludge – The biggest headache with sludge disposal is the effects of the heavy metals and other materials that constituent the sludge. Separating such material with organic material has been a challenge with other methods. However, by using a carbonization plant, you separate the material in gaseous form and ready the material for further processing, creating an opportunity for proper disposal.
The Working Principles of Sludge Carbonizing Plant
The main principle in these machines is thermal decomposition. By making use of thermal decomposition, the vegetal composition of the sludge decomposes and forms carbon and charcoal.
In practice, the decomposition process takes place in three stages, which include:
The Evaporation Stage – The sludge is heated up to 160℃ using combustible material in the raw sludge and added fuel to heat up the entire sludge. Evaporation of liquid constituent also takes place in the first stage.
The Initial Stage – The source of heat from burning the raw material raises the temperature in the furnace, and subsequently initiates the decomposition and the change of molecule.
Total Carbonization Stage – This is the last stage, where the content is totally carbonized and converted charcoal and carbon.
