USA Sludge is devoted to the research and development of wastewater heat pump sludge dryers. With its state of the art technology, these are the most advanced sludge drying machines in the world.
Through implementing a fin type regenerative cycle, combined with a double and triple effect heat pump cycling that works with controlling air humidity and moisture. The pump motor has a frequency converter that allows for a variable range in regulating the drying process of wastewater and sludge. This brings down the moisture level by using an independent air system that allows for quick dehydration of sludge while shortening the drying time. This dramatically lowers the cost of sludge drying by reusing the heat that would normally be discarded in the traditional sludge dryers and systems.
