Process water used to transport the waste is returned to the plant after the solids have settled out. It is preferable to use a closed-loop operat-ing system, where possible, to avoid a liquid ef-fluent. In many climatic conditions, however, this is not possible, and an effluent is generated that contains phosphorus (as PO 4), fluorides, and sus-
