What will dissolve uric acid crystallizations clogging pvc pipes in a commercial hog farm operation? Surfactant must be non dangerous to the water table as pig effluents are drained into a lagoon. The pipe clogs are a tremendous annoyance as pipe joints must be cut out and removed. A chemical dissolver would be of help.
