Energyoptimized integration of sewage sludge drying in sewage treatment plant operations the heat for drying the dewatered sewage sludge is taken entirely from the sludge gas. the sludge gas is used to heat the fluidized bed dryer with an efficiency of 90 in modern incineration plants.
Evaporation rates for biosolids applications from 500 to 10,000 lbs. of water per hour per dryer. the ks paddle sludge dryer provides a reliable and efficient method for drying filter cakes and centrifuge concentrates. the ks paddle sludge dryer is indirectly heated.
First huber belt dryer for sewage sludge in the usa. the huber belt dryer bt 52 in mooresville is the first of its kind in whole usa. in 2011, huber usa won a public tender for an innovative drying concept with a total investment volume of approx. us 3.8 million. the tender requirements included simple and easy equipment operation, a dust.
Fish sludge in the digestate increased the fertilisation effect, but requires optimisation of the biogas process. a simple logistics analysis conducted for a case hatchery showed that onsite drying and codigestion of fish sludge in a central biogas plant can be regarded as equal in terms of costs. norway can become an exporter of fish sludge.
Huber solar active dryer srt: the basic principle of the system is drying of sewage sludge in a glasshouse using the incident solar radiation. a special sludge turning system performs both spreading and turning of the sludge as well as its transport from one side to the other.
