properties of cement were tested in the laboratory its specific gravity is, fineness %. Hypo Sludge In the present investigation work Hypo sludge was collected from the West Coast Paper Mill, Dandeli (Uttar Kannada). Properties of Hypo Sludge are as follows Specific gravity, Moisture content % and fineness %.
Cement kiln coprocessing sludge setup The dewatered sludge was obtained from the municipal wastewater treatment plants around the Yue Bao cement plant. The moisture content of this sludge was approximately about 80%. Given the high moisture content and low calorific value of dewatered sludge, the cement plant built sludge tank with a carriage.
Cement Industry has a 5% share of the global industrial energy consumption. It is one of the highly energy intensive industries. About 80% of the energy consumption for cement production, is at the rotary kiln system for the clicker production. These rotary kiln systems have to be maintained at high temperatures of 900 °C – 1500 °C

Bauxite tailings, also known as red mud, red sludge, bauxite residue, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).
ThermoChemical Approach for the Recovery of Phosphorus from Sewage Sludge A sketch of the reactor with the principle mass flows is shown in the following picture. In order to explain possible side reactions of the process, table 1 shows an orientating

Apr 12, 2016· The breakthrough process also produces a highphosphate fertilizer that can serve as a revenue source for treatment plants. AirPrex serves as a complete biosolids optimization and phosphorus recovery process that takes place after a plant's anaerobic digestion process but before sludge dewatering. Efficiencies gained result in the ability to:
First, What is sludge pyrolysis retorting gasification?. Sludge pyrolysis retorting gasification is to use a composite heating mode to heat the sludge to 150 ° C ~ 600 ° C, the organic matter and water are separated from the solid phase and converted into gas phase; then enter the filter device to filter out the dust in the hydrocarbon vapor.
Drying sludge using exhaust waste heat from processes like power generation from sewage gas or other green gas sources optimises thermal heat recovery and reduces CO₂ emissions. Dry granulate produced by Stronga drying technologies can be used both as fuel and soil improver. Using the most intelligent drying equipment.
These changes are directly related to the solids content. For example, extremely wet sludges and extremely dry sludges require substantially less torque than sludges in the plasticstickyphase, when high torque is required. The KS Paddle Sludge Dryer is designed with high torque capabilities to increase its process flexibility.
Sludge Dewatering. Sludge dewatering is the separation of a liquid and solid phase whereby, generally, the least possible residual moisture is required in the solid phase and the lowest possible solid particle residues are required in the separated liquid phase ("the centrate").
General Introduction. The oil sludge extraction equipment of LCDRI is mainly used to deal with the oil sludge generated by the accident due to drilling, workover, oil recovery, gathering and storage, etc. during the process of crude oil exploitation.
Waste Oils / Oil Recovery Applications. Hiller machines provide worldclass standards for highperformance decanter centrifuges specially equipped to meet the separation requirements of the waste oil processing industry with specialized separation equipment and systems technology.
Thus, the Dutch CDEM process (International Patent, 2006) represents a pioneering recovery system, where the paper sludge is treated at temperatures of around 730ºC, in a fluidized bed combustion system, so as to activate the latent pozzolanic properties of its mineral content. The CDEM process was industrialized after the pioneering work of ...
