The Lemar drying system consists of two indirect dryers in series.
The primary dryer is designed to take the sludge as a thin film through the sticky plastic phase, without the need for back-mixing and produces free flowing material with a solid content of between 55% and 65%.
This passes into a secondary disc dryer which produces dried sludge with a dry solids content in excess of 93%. At this point, the sludge has been processed at sufficient temperature and residence time to ensure pathogen and vector attraction reduction in compliance with USEPA rule 503 and other similar legislation.
The biosolids can then be applied to land as a fertiliser any restrictions on use depending solely on heavy metal and organic contaminant levels in relation to local regulations.
Alternatively the biosolids can be used as a fuel for the Lemar Vitrification process.
