➤ Solar drying of sewage sludge ➤ ➤ WASTE WATER Solutions Dewatered sludge to be dried is spread out on the floor inside a greenhouse structure. What are the reasons to dry sludge with the HUBER SRT solar sewage sludge drying system? ➤ Reduction of disposal costs due to energy provided for free by the sun ➤ Stable, homogenous dry sludge granulate for versatile use, easy to handle and store ➤ Low operating costs due to robust system design, well-proven control and use of efficient motors ➤ Suitable to handle even problematic sludge – due to a unique sludge bed management Operating costs are low...

➤ Sludge feeding and removal ➤ ➤ The HUBER SRT System offers all options for sludge feeding, processing and removal: ➤ Peak loads are prevented through continuous feeding of wet sludge and removal of dry granulate. Batch operation is optionally possible nevertheless, i.e. the drying area can completely be filled with sludge or emptied completely at once. ➤ The dry granulate can be removed either on the same gable side where the wet sludge is fed or on the opposite gable side as the sludge turner can transport back the dry sludge. ➤ Sludge feeding and removal can be automated (with screw conveyors)...

➤ HUBER climate control system ➤ ➤ WASTE WATER Solutions The HUBER climate control system simulates the evaporation efficiency with different settings of the ventilation system. Depending on the result of the simulation, different control and activation schemes are used for the ventilators. This simulation ensures that a specific electric power consumption can be maintained. The basis for the simulation are the values measured by the climate sensors, such as: ➤ Global radiation, temperature and air moisture outside the greenhouse ➤ Air moisture and temperature inside the greenhouse ➤ Sludge bed...
