Industrial wastewater BMPs are considered an adjunct to engineered treatment systems. Typical BMPs include operator training, maintenance practices, and spill control procedures for treatment chemicals. There are also many BMPs available which are specific to particular industrial processes, for example:
* source reduction practices in metal finishing industries (e.g. substituting less toxic solvents or using water-based cleaners);
* in the chemical industry, capturing equipment washdown waters for recycle/reuse at various process stages;
* in the paper industry, using process control monitoring to optimize bleaching processes, and reduce the overall amount of bleach used.
