Leading-edge technology & process development expertise

Envirogen offers a range of environmental and process solutions for water management that can help meet environmental goals and reduce costs.

Meeting Compliance Challenges

With regulations in place covering Flue Gas Desulfurization (FGD) Wastewater and Coal Combustion Residuals (CCRs), Envirogen has leading-edge solutions for treating metals, selenium, nitrate and other contaminants.

FGD Wastewater

Today, Envirogen Technologies offers the most reliable biological technology for treating FGD wastewater: The Fluidized Bed Reactor (FBR). In addition to delivering the most consistent removal of selenium and other metals, the FBR technology offers the benefits of greater system reliability and significantly lower costs than other commercially-available technologies. Envirogen has the broadest background and installation-base of biological treatment systems for both selenium and other oxyanions in the environmental industry. This track record of designing, building and operating biological systems offers the engineering community and power utilities a strong partner in developing reliable, least-cost solutions to managing FGD wastewater treatment operations to meet Effluent Limitation Guidelines (ELGs).

Legacy Wastewater and CCR Leachate

Envirogen offers a solution for meeting selenium and other metal discharge requirements associated with legacy wastewater and CCR leachate. Our Advanced Metals Removal System (AMRS) utilizing select Zero Valent Iron media is a stand-alone technology for a number of metals. Or AMRS can enhance traditional physical/chemical metals removal systems by adding the capability of polishing especially recalcitrant metal forms (e.g., selenate) downstream. A recent validation study conducted on legacy wastewater stored in an ash pond demonstrated the performance of the AMRS to remove selenate from 200-250 μg/l down to below 1 μg/l.

CCR Impacted Groundwater

For sites where the groundwater may be impacted by CCR leachate, Envirogen offers groundwater extraction and treatment systems for hydraulic control, removal of arsenic and other metals, O&M services and groundwater monitoring. Envirogen has extensive experience treating selenium, arsenic, mercury, chromium, lead, thallium, iron, manganese, aluminum, vanadium, cadmium, copper and other metals.

Research, Development and Piloting Capabilities

In addition to designing full scale systems, we also offer small, bench-scale studies and on-site pilot-testing to validate system design and fully meet the client’s requirements. Using fundamental research, we can identify the optimal and most effective system for a particular treatment.
