Sludge Treatment Services
Sludge effluents from the municipal sector (e.g. sludge from wastewater treatment plants) and from the paper-making industry (e.g. de-inking sludge) constitute a major challenge for waste management worldwide. Common sludge management practices of land-filling and land-application are under increased environmental scrutiny and are becoming increasingly costly.
Sludge material usually has very high moisture content, making it difficult to treat. Moreover, in the case of municipal sludge, the material also has a high concentration of pathogens which require treatment before disposal.
Lakson provides state-of-the-art solutions to grind and dewater sludge, and to destroy the presence of pathogens. The fine/dry powder produced by Lakson’s solution meets the requirements of Class A biosolids with respect to pathogen kill, and can be used in both thermal and non-thermal applications to generate revenues.
Our solutions use a proven multi-step approach to grind/dewater sludge and to eliminate the presence of pathogens. The technology combines these operations into a process that uses less than a third of the energy consumed by conventional dryers.
The drying process is electrically driven and does not rely on the combustion of fuels for any heat input. There are no flue gases to treat, as in conventional dryers.
Rather, our solutions rely on mechanical forces, coupled with a recycling mechanism, to dewater sludge. The end-product of Lakson’s process is in dry/fine powder form.
The sludge powder produced by Lakson’s solution meets the requirements of Class A biosolids with respect to pathogen kill; our solution is thus ideal for the processing of wastewater sludge.
Lakson’s sludge treatment solutions have the following advantages:
- small footprint (compact solution)
- no carbon footprint, as no fuel is burned
- lower capital and operational costs relative to conventional systems
- fully automated system
Our approach can be used to treat industrial or municipal sludge, including sludge from paper-making industry (e.g. de-inking sludge) or wastewater treatment plants, into a fine/dry powder that is pathogen-free and without odour. Our solutions can be used in the following applications:
- reduction of harmful reduce harmful waste volumes, so as to comply with environmental regulations and prevent costly and harmful land filling;
- in the case of municipal sludge, the treated product can be used as a high value-added fertilizer (Class A) for the agricultural industry;
- the treated product can also be used in a thermal application, either through direct combustion or by transforming into other forms of bio-fuels.
