Laboratory Analysis and Treatability Studies

Regulatory changes and new production processes often require significant laboratory development and testing. For over 60 years, Chester Engineers has provided chemical, biological, and other in-lab and in-the-field treatability testing services to assist clients in solving some of their most complex challenges. We have also completed numerous R&D projects for clients such as the U.S. Department of Energy, USACE, Maryland Department of the Environment Power Plant Research Program, Environmental Quality Company, US Steel, and US Steel Mining.

Our treatability testing services use the following:

    Physical/Chemical Treatment Processes
  • Microfiltration, ultrafiltration, nanofiltration, reverse osmosis
  • Electrochemical processes
  • Standard chemical treatment
    Biological Treatment Processes
  • Activated sludge processes
  • Anaerobic processes
  • Membrane biological processes

Chester Engineers’ laboratory is located at the University of Pittsburgh Applied Research Center (UPARC). Under the UPARC partnership, we have the ability to lease an additional conventional or pilot area for the duration of a client project; in addition, we can apply new technologies being developed there to resolve client challenges.

Quality Control is a Top Priority

Quality assurance and quality control (QA/QC) is extremely important in treatability testing and in the laboratory in general, as treatability studies that are used for the basis of engineering designs and project permits are subject to a high level of regulatory scrutiny. Data quality objectives are established for each Chester project, ensuring a generation of data that is of known, acceptable, and defensible quality.

Our QA/QC objectives ensure that soil and groundwater samples are representative of the medium being evaluated, have appropriate preservation, and are handled, labeled, stored, documented, and transmitted to the laboratory under appropriate chain-of-custody procedures.
