The article describes a scheme developed by CH2M Hill to treat FGD wastewater and remove heavy metals.
Remove heavy metals from wastewater over a wide pH range. Use chemical solutions for soluble and/or particulate heavy metals, such as lead, copper, chromium, iron, manganese, mercury, nickel and zinc. Remove selenium with advanced biological treatment. Remove heavy metals from industrial and municipal wastewater to meet effluent guidelines….
Treatment occurs as the wastewater flows upwards through this bed and the dissolved pollutants are absorbed by the biofilm (Young, 1983). Anaerobic filters were the first anaerobic systems that eliminated the need for solids separation and recycle while providing a high SRT: HRT ratio. Various types of support material can be used, such as ...

GE announced that American Electric Power (AEP) is installing GE's ABMET® wastewater bioreactor system at the utility's Mountaineer coal-fueled power plant in New Haven, W.Va. GE's proprietary biological treatment system uses a special molasses-based product as a nutrient for microbes that reduce selenium, a constituent found in many coal-fired power plant water emissions.
The ZENON ABMet® system is built around an advanced biological wastewater treatment process that uses naturally occurring non-toxic, non-pathogenic microbes in specially developed mixtures, which reduce and precipitate target compounds from solution, or convert target compounds into their insoluble chemical components.
A Non-Biological Process for Selenium Removal from Industrial Wastewater. Posted by ChemTreat On 07/27/2020. One of the primary, and heretofore costly-to-remove, contaminants in coal-fired power plant wastewater streams is selenium. Concerns now abound regarding selenium toxicity in other streams, including mine tailings wastewaters, oil refinery discharge streams, and even …
The ABMet system targets nitrates/nitrites and selenium removal in a single step, after treatment for mercury via chemical-based MetClear. A prototypical deployment of the system at American Electric Power's 1.3 GW Mountaineer power plant (New Haven, W.Va.) demonstrates its performance: surpassing FGD effluent discharge limits with selenium ...

Wastewater Treatment Systems The Need for Wastewa-ter Treatment Wastewater treatment is needed so that we can use our rivers and streams for fishing, swimming and drinking water. For the first half of the 20th century, pollution in the Nation's urban waterways resulted in frequent occurrences of low dissolved oxygen, fish kills,
We've found the following treatment scheme to be successful. First, the wastewater's pH is lowered with some inorganic acid (sulfuric, muriatic/hydrochloric) to a pH of around 7.0. We then feed a ferric-based coagulant to help precipitate the molybdenum. Normally we have to feed the coagulant at a rate of at least 15× the moly concentration.
While selenium is typically difficult to remove from wastewater, ABMet enables the metal to be captured and removed from the wastewater stream. The new wastewater treatment plant has been designed to treat 24 L/s of flow and to meet effluent targets. The targets will reduce nitrates from 85 mg/l to 3 mg/l and selenium from 130 µg/l to 5 µg/l.
