This by-product of wastewater treatment needs careful management, and requires significant planning for long term sustainability. Nicholas O’Dwyer services include sludge quality analysis; nutrient analysis; energy recovery, sludge treatment and beneficial re-use analysis.
We have prepared many regional sludge management plans where our team have carried out detailed site inspections, assessment and quantification of the sludge arisings and sludge transport modelling and surveys. The methodology and modelling we employ provides the fully validated calculations required to justify the management plans and the investment decisions.
Our modelling looks at the whole lifecycle of sludge: from its production at treatment plants through to its disposal or recycling. Strategic decisions can then made after full consideration of the whole sludge lifecycle, from production to recycling and taking account of the strongly interlinked nature of sludge operations.
We have developed design solutions for all aspects of sludge treatment from coppicing solutions to advanced technologies such as thermal drying.
