摘要: A method of treating industrial waste waters is provided. Specifically, the wastewater includes one or more organic contaminant materials and pre-treated prior to filtering by following steps. The pH adjusted a in range about 2 6, combination iron salts peroxide are added allowed react for period at least three minutes. Next, upwards value 7 precipitating flocculating agents form an insoluble bearing compound. compound then filtered from thereby removing wastewater. This invention particularly suited use with single pass flow-through filters, most suitable high flow rate filters. present results minimization filter clogging maintenance filtration rates, reduced need cleaning cycles using lengthy treatment acid based detergent mixtures.
