tonnes of domestic sewage treated every day at a single plant Haarslev's technology now serves
China and southeast Asia are a fast-growing market with an urgent need for effective, large-scale sludge treatment. Urbanisation, changing living patterns and rising living standards are producing huge volumes of organic sludge — and it has to be dealt with reliably, efficiently and at scale.
From 150 to 800 tonnes a day — the scale keeps rising.
Three of the region's largest sludge plants run on Haarslev disc dryers.
