USA Sludge products

USA Sludge uses the most energy efficient, technically advanced and affordable wastewater treatment system. The wastewater solution includes a multi plate dewatering screw press, dissolved air flotation and the low temperature heat pump sludge dryer.  Together this technology is effective without using digesters and treats all types of wastewater.

Sludge dewatering is an important step in sludge treatment as it determines the amount of and quality of sludge.  Working with all varieties of complex industrial wastewaters, this multi plate sludge dewatering screw press produces a high quality and quantity of sludge.

Dissolved Air Flotation (DAF) is efficient in the process of removing suspended solids, oils and other contaminants, BOD, COD and TSS through the use of air bubble flotation.

USA Sludge uses an advanced heat pump technology, our low temperature sludge dryer operates at a temperature between 120 – 185 degrees Fahrenheit. Recycling waste heat that is generated in the machine increases efficiency and lowers the energy needed to dry sludge.  Moisture that is trapped inside the cabinet, a by-product of sludge drying, then moves through a heat exchanger, where the air is condensed to water.  This condensate water can be used as reclaimed water.

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.
