Excess Sludge from SBR Tank is collected in Aerobic Digester for further stabilization. It is then pumped through the Sludge Dewatering System (Filter press) for dewatering.
Aerobic & Anaerobic Digestion
In an anaerobic system there is an absence of gaseous oxygen. In an anaerobic digester, gaseous oxygen is prevented from entering the system through physical containment in sealed tanks. Anaerobes access oxygen from sources other than the surrounding air. The oxygen source for these microorganisms can be the organic material itself or alternatively may be supplied by inorganic oxides from within the input material. When the oxygen source in an anaerobic system is derived from the organic material itself, then the 'intermediate' end products are primarily alcohols, aldehydes, and organic acids plus carbon dioxide. In the presence of specialized methanogens, the intermediates are converted to the 'final' end products of methane, carbon dioxide with trace levels of hydrogen sulfide. In an anaerobic system the majority of the chemical energy contained within the starting material is released by methanogenic bacteria as methane.
In an aerobic system, such as composting, the microorganisms access free, gaseous oxygen directly from the surrounding atmosphere. The end products of an aerobic process are primarily carbon dioxide and water which are the stable, oxidized forms of carbon and hydrogen. If the biodegradable starting material contains nitrogen, phosphorus and sulfur, then the end products may also include their oxidized forms- nitrate, phosphate and sulfate. In an aerobic system the majority of the energy in the starting material is released as heat by their oxidization into carbon dioxide and water.
Advance Sludge Dewatering
Excess Sludge from SBR Tank is collected in Aerobic Digester for further stabilization. It is then pumped through the Sludge Dewatering System (Filter press) for dewatering.
Filter Press
The filter press is used for sludge dewatering. The solid/liquid separation process with the filter press is obtained through filtering cloth and plate under hydraulic pressure.
Hazardous Sludge Treatment
Incineration
Incineration is a disposal method that involves combustion of waste material. Incineration and other high temperature waste treatment systems are sometimes described as "thermal treatment". Incinerators convert waste materials into heat, gas, steam, and ash.
Incineration is carried out both on a small scale by individuals and on a large scale by industry. It is used to dispose of solid, liquid and gaseous waste.
