USA Sludge’s high tech solar sludge drying creates a much smaller solar footprint, as our system uses solar electric panels that we install at the site of the dryer, which reduces installation costs and increases efficiency. The closed cabinet dryer with a low temperature heat pump requires less electricity to operate because the heat pump cycle utilizes all of the waste heat to dry the sludge which makes this process three times more efficient than a standard solar dryer. When the dryer is not in use, the electricity from the solar panels at the dryer site, is redistributed to the treatment plant, therefore the solar energy never goes to waste. Maintenance is a breeze as there are no moving parts, less labor costs, and no buildings to maintain. Odor control issues and burn permits are eliminated.
Our solar sludge drying solution accepts non stabilized sludge at 1% solids and can dewater and dry the sludge to 90% solids. The bio-solids are then automatically bagged and ready for shipment, resulting in lower costs, is odor free with effective results. The drying time for our solar dryer is ONLY TWO HOURS compared with standard solar dryers that take 10 DAYS. This high tech system is sustainable and saves industries and companies valuable time and money, allowing for future growth, all while exceeding the EPA 503 quality requirements for Class A bio-solids.
