Disposal of that sludge which contains 20 dry solids is very difficult without drying process moreover it has negative impact on environment as well solar drying system is based on the greenhouse effect where sludge is spread into a greenhouse and mixed mechanically with a mixing device periodically
Dec 12 2016 the climatic data revealed on site with a yearly average solar radiation of 605 kwh m 2 day and air temperature and relative humidity of 2992 k and 28 respectively in addition to the capital and operating financial factors had favored the use of solar drying application as an appropriate mean to treat 100 10 6 kg 20 dry solids
Solar sludge drying is an ideal method of reducing sludge volumes and disposal costs particularly in the australian climate the huber srt system is a unique and highly efficient process whereby sludge is dried in a greenhouse using incident solar radiation and artificially generated wind to evaporate water from the sludge
Largest solar sewage sludge drying site in southern germany fully equipped by huber in a new sludge treatment plant in bayreuth the sludge from 300000 pe is dewatered and dried fully automatically with the use of exhaust heat and exhaust air treatment
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 at the same time the fluidized bed dryer
To lower the sludge volumes in order to decrease costs for further downstream processing including transport storage and incineration costs mechanical dewatering and thermal drying of sludge are important onsite unit operations in cpi wastewater treatment plants wwtps sludge management in industrial sludgehandling installations is and
