System Design & Permitting

When designing a wastewater treatment system, EMG has extensive experience supporting our clients through the process of obtaining appropriate permits and approvals for the project. Depending upon the plant’s location, a unique set of county and state regulations will apply. Additionally, if the ultimate discharge point is to a receiving body of water or the ground, the client may need to apply for a State or National Pollution Discharge Elimination System (SPDES or NPDES) permit. EMG has successfully supported our clients through these sometimes complex processes. We have a wealth of experience in creating detailed systems designed for optimal performance, as well as successfully supporting our clients in obtaining the necessary permits and approvals.


High-Rate Anaerobic Biological Treatment

Today’s highly competitive business environment places emphasis on achieving consistent regulatory compliance, low operational costs, and energy efficiency, all within the smallest possible footprint. Historically, it has not been possible to get all of these benefits in a single treatment system, but this is achievable with the PurEffluent Anaerobic Fluidized-Bed Digester (AFBD) technology developed, designed and optimized by EMG. Our PurEffluent Anaerobic Fluidized Bed Digester (AFBD) process removes 85% to 95% of biodegradable waste stream organics (BOD5 or COD) and converts them into usable biogas (CH4 and CO2), which can be used for on-site process heat or electricity generation, at low operational costs and with a compact and efficient design.

EMG has the advanced technical knowledge and engineering expertise to provide our clients with turnkey services that include:
  • System design and permitting assistance
  • Component fabrication
  • System installation/construction supervision
  • System shakedown and start-up
  • Advanced control software providing remote, fully automated system monitoring


Renewable Energy Generation

Biogas is the primary by-product of anaerobic digestion. It has a high heat (BTU) content and can be used as a renewable energy source. Because the PurEffluent AFBD system is a high-rate process, with a low Hydraulic Retention Time (HRT), the captured biogas stream is partially scrubbed and has a high methane concentration – typically exceeding 70%. EMG will help our clients use this valuable renewable energy source in a variety of ways such as:
  • Fuel for a Combined Heat & Power (CHP) system
  • Fuel for an existing or a dedicated boiler unit
  • A Renewable Natural Gas (RNG) source following processing and compression that can be injected into a nearby Natural Gas Pipeline.
The value of this renewable energy stream significantly improves the financial benefits and the Return On Investment (ROI) from our anaerobic wastewater pre-treatment systems. This “Waste-to-Energy” approach is a compelling reason to not let your process wastewater flow down the drain.


Polishing Process

EMG’s PurEffluent Anaerobic Fluidized Bed Digester (AFBD) system is the best solution for the majority of our clients due to superior efficiency and reliability, low Operating and Maintenance (O&M) cost, and significantly lower sludge production. This is in contrast to aerobic treatment processes, which convert the biodegradable organic content of wastewater streams (BOD5 or COD) into Carbon Dioxide (CO2) and new biomass (sludge). Aerobic systems are significant energy consumers and produce approximately ten (10) times more waste sludge than anaerobic systems for the same application. This often results in high O&M costs for aerobic systems when used as the primary treatment process. However, aerobic systems can facilitate compliance with strict final discharge permit limits (IU, SPDES or NPDES) for BOD5, TSS, Nitrogen (N) and Phosphorous (P) as a secondary or polishing process. When needed, EMG provides systems for polishing processes that rely on Aerobic, Anoxic, or other physical/chemical technologies such as:
  • Dissolved Air Flotation (DAF) Systems
  • Sequencing Batch Reactor (SBR) Systems
  • Aerobic Fluidized Bed Reactor (FBR) Systems
  • Nitrification and De-nitrification (N-Removal and Reclamation) Systems
  • Phosphorous Removal (P-Removal and Reclamation) Systems


System Operation & Service

The EMG PurEffluent AFBD Systems are designed and installed to run smoothly and efficiently with low operating costs. To keep the system performing at optimal levels, there are basic daily, monthly and annual tasks and maintenance requirements. Not every client has the capability or desire to assign resources to the wastewater pre-treatment system. Therefore, EMG offers maintenance plans to ensure the system is operated and maintained as designed in order to provide the maximum benefits to the plant.

Environmental Consulting Services

Hazardous Waste Management
Hazardous waste treatment and disposal is one of the most rapidly developing areas of environmental engineering. Hazardous waste management is closely regulated by the EPA under the Resource Conservation and Recovery Act (RCRA). In addition, federal, state, and local regulations require waste tracking systems, appropriate waste treatment and disposal, and management programs that reduce waste through industrial process changes. EMG is experienced in determining the health, safety, and environmental effects of hazardous wastes, conducting hazardous waste characterizations, and developing waste treatment alternatives. Our team combines in-depth knowledge of regulatory requirements with superior technical and scientific expertise to address client needs in these areas. Effective solid waste management safeguards public health and protects the environment by controlling waste from generation through disposal. Integrated solid waste management incorporates life-cycle analysis, source reduction, recycling, incineration, and land filling, together with ongoing monitoring and evaluation, to ensure that the management strategy meets current and future regulations and is operating efficiently. EMG has extensive expertise in available solid waste management practices and technologies, and we use that knowledge to develop a comprehensive waste management strategy.

Environmental Compliance
Maintaining regulatory compliance is an important part of operating a facility or owning property. Making sure that the facility or property adheres to environmental regulations helps an owner or operator avoid costly corrective actions, prevent government-imposed penalties, and preserve intrinsic property value. Environmental audits and site assessments are two methods of ensuring that owners stay in compliance - from acquisition through operation to final disposition. Environmental compliance audits are the most effective way to identify deficiencies and areas of potential noncompliance. A thorough audit evaluates permit and compliance status with respect to federal, state, and local regulations. It typically covers areas such as waste generation and disposal, storage and process tanks, air emissions, safety and health hazards, and hazardous materials handling. As a form of due diligence, site assessments are critical to assessing the potential environmental problems associated with a site before any property transactions occur. EMG has a wealth of experience providing a variety of compliance support services. In essence, we become part of a client’s “team” - representing and protecting the client’s best interests. We evaluate client procedures, operations and policies. If we identify a deficiency, we ensure client confidentiality and recommend a plan for corrective action.

  • Defining environmental liability and assessing risks
  • Identifying technologies and best management practices to enhance compliance while reducing permitting requirements, control and treatment equipment expenditures, and sampling efforts
Pollution Prevention
Until recently, U.S. Environmental Protection Agency (EPA) regulations and most environmental consultants focused on “end-of-pipe” control measures. Essentially, this means that industry achieved compliance by controlling and treating hazardous waste, air emissions, and effluent discharges after these pollutants were generated. However, the benefits of preventing pollution before it occurs, rather than treating it after the fact, are far greater. Pollution prevention (P2) means designing new processes and facilities that minimize the production of pollutants and evaluating existing operations to identify pollution prevention opportunities. Effective pollution prevention efforts both decrease regulatory and financial burdens and ensure more efficient and safe operations. EMG has always maintained a proactive philosophy with regard to environmental engineering. We understand that the best way to reduce the costs and regulatory liability of hazardous wastes and other pollutants is to eliminate them―not merely treat or dispose of them. Although zero discharge is rarely an achievable goal, our P2 solutions not only dramatically decrease the output of pollutants, but also create a return on investment that can rarely be realized through “control technologies.”

We accomplish this by offering a full spectrum of pollution prevention services that include identification of P2 opportunities.

Although most businesses make every effort to operate in a safe and environmentally friendly manner, mistakes sometimes happen. Whether this is in the form of a small surface or subsurface spill, or a recently discovered illegal hazardous waste dump, it is important to address such problems quickly and effectively. While it is imperative to ensure that the selected treatment technology will work on a specific contaminant in a specific media, deciding the best remedial alternative constitutes only one facet of a successful remediation effort. Of equal importance are coordinating remediation, transport and disposal activities and maintaining lines of communication with the appropriate governing bodies. EMG understands the value of ensuring each of these areas is addressed effectively and comprehensively. We have the experience and flexibility to address remediation projects - whatever their size.
