Comprehensive Wastewater Solutions – Municipal and Industrial Applications

With increasing population and industrial activity, higher levels of treatment are essential before discharging both municipal and industrial wastewater. The United Nations Sustainable Development Goals (UN SDGs) have set clear targets for improving water quality, promoting integrated water resource management, enhancing water use efficiency, and restoring water-related ecosystems.

Envirogen specializes in providing comprehensive wastewater solutions for both municipal and industrial applications. With a commitment to excellence and environmental sustainability, our team delivers tailored solutions to address even the most complex water and wastewater challenges, including:

• Organics and nutrient removal from wastewater
• Selenium and other metals removal from wastewater
• Wastewater reduction and reclaim
• Industrial non-wastewater applications
• Emissions and odor control applications
• Life cycle cost solutions – performance warranties

Effective removal of organic material (i.e., total organic carbon, volatile organic compounds) and nutrients, such as nitrogen and phosphorus, is essential to maintain water quality and prevent environmental contamination. Envirogen’s proprietary fluidized bed reactor (FBR) technology has been used to remove harmful organics and nitrogen from chemical production plant wastewater. The FBR has also been employed at Publicly Owned Treatment Works (POTWs) to remove nitrogen from wastewater before it is discharged. This technology can help municipalities meet strict nutrient removal mandates and enabled them to gain nutrient credits, which can be sold to other dischargers, offsetting treatment costs and creating additional revenue streams.

Envirogen also offers membrane bioreactor (MBR) systems, which can be customized for specific applications, including landfill leachate treatment. For more stringent discharge requirements, the MBR system can be complemented by nanofiltration (NF), reverse osmosis (RO), or activated carbon (AC) treatment.

Additionally, we offer granular activated carbon (GAC) systems for organics treatment on both potable water and wastewater applications. We can also provide specialty absorbents for the treatment of specific contaminants.

Envirogen FBR systems

Envirogen has the expertise and experience to effectively remove selenium and other metals from complex industrial wastewater streams, including flue gas desulfurization (FGD) effluent at coal-fired power plants, sour water stripper bottoms at refineries, and runoff water from strip-mining operations.

Our proven selenium treatment technologies include the biological fluidized bed reactor (FBR) and the advanced metals removal system (AMRS), which utilizes zero valent iron (ZVI) media. In addition, we offer systems utilizing specialty resins for a variety of applications, including chelating resins for the selective removal of specific metals, brine softening, and other substances. These solutions offer cost-effective compliance options, tailored to specific industrial requirements, and can be seamlessly integrated into broader water treatment processes.

• Specialized selenium treatment solutions for refineries, along with a fact sheet on our treatment experience.

Other metals:

In addition to selenium, our technologies are highly effective in removing other metals such as mercury, arsenic, chromium, iron, manganese, uranium, cobalt, molybdenum, and other regulated ions from industrial wastewater streams, ensuring regulatory compliance and environmental protection.

Water conservation is essential for both municipal and industrial operations, where large volumes of water are used directly in production processes, as a component of the final product, or indirectly through energy consumption. By recapturing and recycling wastewater, industries can avoid discharge costs and reuse water for a variety of applications, including washing, rinsing, plating, cooling, boiler make-up, and fire suppression systems. The choice of method depends on the water’s quality, volume, and intended reuse, with factors like space and budget influencing the best approach.

One effective solution is PureSep dNF (direct nanofiltration), an excellent choice for surface water treatment and waste stream recycling. PureSep dNF offers the rejection of dissolved solids with significantly less energy than comparable spiral-wound reverse osmosis processes. Each hollow fiber membrane in this system provides high fouling resistance with no need for pre-treatment, making it a highly efficient option for industries looking to recycle and reuse wastewater.

By virtue of its solids handling capability and salt rejection properties, the PureSep NF
nanofiltration process can replace multiple stages simultaneously.

Envirogen offers a wide range of water treatment solutions for industrial applications, including boiler feed water, process and rinse water, product purification, metals recovery, and water reclaim. Industrial process water – water that has been treated to be safe for use in manufacturing – is essential for maintaining product quality and improving efficiency.

Each of these applications presents unique challenges, and our team of experts can tailor solutions to meet your specific needs. For more details on how we can support your water treatment goals, please contact us to discuss your specific applications and requirements.

Envirogen is at the forefront of industrial and municipal emissions odor control with its biofilter and biotrickling filter technology, designed for the elimination of hydrogen sulfide (H₂S), volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and reduced sulfur compounds (RSCs). With over 130 installations, these systems deliver high removal rates and offer numerous advantages over conventional and thermal odor control systems:

• Simple operation and maintenance
• Reduced chemical usage and storage
• Reduced energy usage
• Lower carbon footprint and overall emissions

Envirogen biofilters and biotrickling filters are available as both modular and built-in-place systems, customizable to meet specific air flow rates and facility space requirements.
