Industrial Waste Treatment.

 

Conducted treatability studies, feasibility studies, pre-design investigations, design plans and specifications, construction management oversight and start-up services for an array of industrial wastewater applications.  Industries have included the leather tanning and finishing, pulp and paper, timber processing, pharmaceutical, electronics, iron and steel, organic chemical manufacturing, electroplating, red meat, fruits and vegetables, and landfill point sources. 

 

U.S.EPA Effluent Guidelines Division/ Washington, DC    

Industrial wastewater treatment investigations in support of developing permit standards in the leather tanning and finishing, pulp and paper manufacturing, pesticides manufacturing, red meat, poultry, seafood processing, pharmaceutical, timber and wood preservative products, and electroplating industries.  Conducted over 50 site visits for U.S.EPA Effluent Guidelines Division to characterize discharges from industries, assess in-plant controls of wastewater discharges, and evaluate the effectiveness of industrial treatment plants.  Responsible for cost estimates for the recommended treatment technologies and the specific cost to upgrade existing plants.  


Lincoln Pulp & Paper/Lincoln, ME       

Senior engineer for the Lincoln Pulp & Paper wastewater treatment plant upgrade.  Evaluation included in-plant assessment of water reuse and heat reduction opportunities, analysis and recommendations for mitigating excessive heat at the secondary biological process that limited biological treatment during summer months, identifying process options for mitigating solids carryover from the secondary clarifier, and primary and secondary sludge conditioning and dewatering enhancements.  


U.S. General Office for Industrialization/Washington, DC        

Senior design engineer responsible for designing pollution control technologies to the General Office for Industrialization.  Control technologies included chrome recovery, chromium reduction, cyanide oxidation, steam stripping, off-gas control, and biological treatment processes related to the leather tanning and pharmaceutical industries in Egypt.  


U.S.EPA Office of Solid and Hazardous Waste/Washington, DC        

Served as the project manager for the Paragraph 4(c) study funded by the U.S.EPA to identify the relative presence and contribution of dioxin to the environment from the pulp and paper, pharmaceutical, electronics, and the organic chemical manufacturing industries.  


Lockheed Martin Aeronautics/ Marietta, GA    

Design engineer responsible for the assessment and upgrade of industrial and sanitary wastewater treatment facilities at the Lockheed Martin campus in Marietta, GA.  Primary focus was to identify appropriate technologies for implementation in order to treat both metal bearing industrial wastes and sanitary wastewater, and to recycle/reuse the effluent as process water throughout the Lockheed Martin campus.  


Beloit Paper/Dalton, MA        

Process engineer responsible for pilot treatability studies relating to new treatment processes being developed for implementation within the pulp and paper manufacturing industry.  Responsible for all permits and licenses to allow the testing at the Beloit facilities in Dalton, MA, and data monitoring and reporting as an independent third party.  


Miscellaneous Municipal and Private Landfill Operations/New England    

Design engineer on an array of landfill leachate pretreatment studies, treatability studies, and design projects throughout New England.  Key issues have included carbonate scaling impacts, sulfide pretreatment, metals removal, odor control, and BOD5 and ammonia treatment.  Clients have included Waste Management Services, Sawyer Environmental Services, Regional Waste Service in Portland, ME; Massachusetts Water Resources Authority; City of Lebanon, NH; City of Franklin, NH; City of Rockland, ME; City of Lewiston, ME; City of Bath, ME; and the Androscoggin Valley Regional Refuse Disposal District in Berlin, NH.  


Lockheed Sanders/Nashua, NH         

Developed and implemented a treatability study to evaluate the effectiveness of oxidation processes as a means of pretreating several sulfur-laden waste streams from the Lockheed Sanders operation.  Specifically, three oxidation reagents (hydrogen peroxide, sodium hypochlorite, and potassium permanganate) were evaluated for pre-treating the industrial waste streams.  


Lockheed Sanders/Nashua, NH         

The Lockheed Sanders micro-electronics facility processes gallium arsenide wafers and generates a gallium arsenide wastewater that exceeded the local pretreatment standards for arsenic.  This assignment included characterizing the waste stream, conducting a pilot treatability study to assess various treatment options and the preparation of details and figures for the recommended treatment option.  Unit operations evaluated were iron coprecipitation, coagulation/flocculation/sedimentation with polymer addition, filtration and activated alumina adsorption, and ion exchange.  


Bath Iron Works/Bath, ME        

Completed an industrial pretreatment study to determine the most economical means of handling the metal-bearing waste stream at the BIW campus.  Study identified potential treatment options (hydroxide and sulfide precipitation, oxidation, and ion exchange), and recommended the appropriate steps in moving forward.  


AVCO Lycoming Textron Stratford Army Engine Plant/Stratford, CT    

Assisted in conducting a review of the existing chemical waste treatment facilities at the AVCO facility in Stratford, CT and the proposed design modification at this facility.  Unit operations included cyanide oxidation by alkali chlorination, trivalent chromium reduction with sulfur dioxide, and combined metals precipitation as metal hydroxides using lime.  The primary focus was on determining if the system was capable of meeting the effluent permit and if the system design was sufficient to proceed without excessive and unusual change orders.
