What do we exactly do for sludge treatment?
Sludge treatment, in order to improve sludge dewatering and produce sludge adapted to the chosen disposal route, while respecting the environment
Where does sludge come from?
From wastewater treatment, in certain cases notably from bio processes, a solid waste or sludge is also produced. Indeed, wastewater treatment reduces the solved and unresolved pollutants existing in the wastewater. These are to be regained in the sewage sludge at the end of the water treatment. In addition to this type of sludge, other sludge exist that require treatment. Amongst these are other organic sludge, from animal origin (manure, slaughterhouse sludge), from food industry, and mineral sludge such as steel industry and dredging sludge, tunnel and drilling sludge, sludge from the construction field, etc. Some types of sludge are a result of natural processes, while other types of sludge are produced in industrial processes such as by filtering of liquids.
Why sludge treatment is necessary?
After the clarification step during wastewater treatment, sludge are very voluminous and still ferment a lot. The goals of sludge treatment are to reduce and ameliorate sewage sludge characteristics for the further utilization or disposal. After their treatment, sludge may be discharged or reused back into the environment.
What do we exactly do for sludge treatment?
Sludge need to be treated, involving multi-process solutions. Sludge are stabilized in order to control the degradation of organic ingredients and to remove odors, their volume is reduced, and they are hygienized (pathogen organisms are eliminated).
Sludge treatment, an elaborate process to recycle or dispose of sludge in a safe, effective and sustainable manner
Sludge treatment, step by step
The sludge accumulated in a wastewater treatment process must be treated and disposed of in a safe and effective manner.
The choice of a sludge treatment method depends on the amount of sludge generated and other site-specific conditions.
The design of sludge management and minimization strategy must target reduction at every step of the sludge generation chain:
- in the production process, to reduce waste and then reduce sludge production,
- in the wastewater treatment plant, by using new adapted technology that reduces the amount of sludge produced per amount of BOD treated,
- in the disposal methods, to select the most stable and most economical route
Sludge treatment is an elaborate process being usually performed in several phases.
Shincci Offers in sludge treatment:
SHS INTEGRATED BELT-TYPE SLUDGE DRYER
SHS WASTE HEAT INTEGRATED BELT-TYPE SLUDGE DRYER
CONTAINER DRYER
These systems have been designed for products where thermal energy is needed in order to remove the remaining water content, to obtain a final product with over 90% dry solids content.
Examples of feed: Municipal sludge, Industrial sludge, AD digestate, Woodchips, Paper refuse, Spent grains, Eucalyptus bark biomass, Solid Recovered Fuel (SRF).
Utilizing the hot water, gas and generator waste heat as the main energy source, the sludge is dried in a greenhouse by circulating dry hot air(40-75ºC), the sludge into carbon-neutral and odorless granules, for eventual agricultural reuse or thermal energy production using co-incineration.
SHINCCI Low Temperature Sludge Drying Solution has helped hundreds of municipalities and industries to improve efficiency, reduce costs, and minimize carbon footprint regarding sludge management.
Our advantages:
Innovative control system, onsite and online combined after-service, over 200 engineers offering technological consultation, rich experience from hundreds installations, unique solution for different plants, strict quality control, long service life of machines, flexible design.
With either electric power or waste-heat as heat source, the Shincci Sludge Dryer can simply reduce the moisture content of wet sludge from 83% to 30-10% (adjustable as required). It is energy-efficient and eco-friendly, and has been extensively applied in municipal and industrial sludge drying. And the dried sludge could be for resource utilization.
