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.

热镀锌废水是一种严重的环境危害。目前，这些废水被卡车运离现场，由承包商处理，沉淀重金属污泥，通过垃圾填埋场处理。工业镀锌，作为澳大利亚最大的热镀锌公司，热衷于消除这种危险。为此，我们将考虑使用一种创新的膜基工艺；从废水中回收有价值的锌和铁化合物，并使水重新利用。如果成功，该项目将导致在工业镀锌现场建造一个试点工厂废水处理厂。
