Uric Acid (C5H4N4O3, CAS 69-93-2) is a white, nearly water-insoluble compound formed when the body breaks down purines. It is a main nitrogen component of bird and reptile droppings. In storage tanks it mainly appears in animal waste, poultry processing and biological wastewater streams, where it can settle as sludge. Wastes containing uric acid are mildly acidic and are usually handled like other organic wastewater. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
Nylon is the most economical tank material for Uric Acid, rated Excellent. HDPE is also rated Good or better. Avoid aluminum hardware.
