水洗涤器可以有效地从过度喷涂的油漆中截留固体，尽管由此产生的废物特性在很大程度上取决于喷漆室水中所选的化学添加剂。化学作用可以设计为在水中产生油漆凝聚或油漆浆，尽管在实践中，处理过的废物通常以各种组合模式表现。本文讨论了废物分类、适用法规以及相关的废物管理原则和选项。

WATER SCRUBBERS CAN EFFICIENTLY ENTRAP SOLIDS FROM PAINT OVERSPRAY, THOUGH RESULTING WASTE CHARACTERISTICS ARE LARGELY DETERMINED BY THE SELECTED CHEMICAL ADDITIVE TO THE SPRAY BOOTH'S WATER. CHEMICAL ACTION CAN BE DESIGNED TO PRODUCE EITHER PAINT AGGLOMERATION OR SLURRY OF PAINT IN WATER, THOUGH IN PRACTICE THE TREATED WASTE OFTEN BEHAVES IN VARIOUS COMBINATION MODES. THIS PAPER DISCUSSES WASTE CLASSIFICATION, REGULATIONS APPLYING, AND RELEVANT WASTE MANAGEMENT PRINCIPLES AND OPTIONS.
