The Effective Treatment of Hot Dip Galvanizing Effluent Streams

热镀锌废水是一种严重的环境危害。这些废水目前被用卡车运到异地，由承包商处理，以沉淀出重金属污泥，然后通过垃圾填埋场处置。工业镀锌厂作为澳大利亚最大的热镀锌企业，热衷于消除这一危害。为此，我们将考虑使用一种创新的基于膜的工艺；从废水中回收有价值的锌和铁化合物，并允许水再利用。如果成功，该项目将导致在工业电炉现场建设一个试点工厂废水处理厂。

Hot Dip galvanizing effluent represents a significant environmental hazard. This wastewater is currently trucked offsite and treated by contractors to precipitate a heavy metal sludge that is disposed of through landfill. Industrial Galvanisers, as the largest hot dip galvanizing company within Australia, are keen to eliminate this hazard. We will consider the use of an innovative membrane based process for this purpose; to recover valuable zinc and iron compounds from the effluent and allow the water to be re-utilised. If successful, this project will lead to a pilot plant wastewater treatment plant being constructed at an Industrial Galvanizers site.
