This Process Employed In A Sewage Sludge Carbonization Treatment Plant

Perhaps you have passes a wastewater treatment plant and wondered exactly how the process works? Most localities have one or more sewage sludge carbonization treatment plant. These plants would be the places where municipal sewage sludge is treated. This procedure is split into three stages. Each stage is made to further decompose and disintegrate wastewater sludge. Microorganisms are used to help treat the sludge.

Once digested, this type of water is removed from the sludge and is particularly dried. The dried sludge bring fertilizer. There are also gases produced during the treatment process which can be used as operating gas engines or as fuel.

Sludge is digested in three stages. The very first stage generates a digested sludge which is mostly solid and dry. Another stage makes a supernatant liquor which consists of finely divided and liquefied matter. Stage three produces decomposition gases like carbon dioxide, methane, and nitrogen. This entire process is carried out in sludge digestion tanks.

Three of the biological action stages that occur during sludge digestion are acidification, liquefaction, and gasification. All the stages adds to the complete decomposition and digestion of wastewater sludge.

Acidification begins the wastewater sludge decomposition process. During this stage, bacteria attacks available food sources in the sludge and begins to anaerobically decompose them. Including soluble nitrogenous compounds and carbohydrates. As being the process continues, it creates organic acids and acid carbonates. Gases for example hydrogen sulfide and co2 will also be produced. Producing these acids results in lower pH values. Read more: http://carbonizationfurnace.com/.

The next stage is liquefaction. Just like it sounds, the matter is liquefied throughout this stage. All solid particles are reduced to either a dissolved form. Cellular enzymes stimulate this hydrolysis there is some fermentation. Ammonia compounds and acid carbonates accumulate and produce hydrogen and co2 gases. There is a quite strong odor and pH values rise. The decomposition gases are trapped through the decomposing sludge. This results in a foam which rises towards the top of the sludge pond. This really is a longer stage compared to first stage.

The final stage of sludge digestion takes place when the other materials for example organic acids and proteins are separated. This stage usually produces huge amounts of methane gas and smaller amounts of co2. The pH value increases again and becomes alkaline.  Because the sludge will continue to decompose, the gas production slows along with the sludge is ready for disposal.

Many sewage sludge carbonization treatment plants have another stage of sludge decomposition. This stage occurs before disinfection which is called advanced or tertiary treatment. This stage involves ion exchange, sand filtration, activated carbon filters, coagulation-flocculation, membrane processing, fine screening or nitrification-denitrification. The process utilized in this stage could differ among localities.

Treating wastewater is a ongoing challenge for almost all communities. It is very important completely treat all sludge before releasing it for disposal.
