Summary

Senior Environmental Engineer and licensed Professional Engineer (PE),

skilled at developing and implementing feasible environmental solutions for

industry. Experience includes project management, operations support and

environmental compliance programs, working for both industry and

environmental consulting firms. Skilled at leading teams to implement

production changes which result in environmental improvement. Highlights:

. Implemented novel wastewater treatment technology to accommodate a 20%

production expansion

. Led pollution prevention team to achieve 40% reduction in total

dissolved solids in wastewater

. Facilitated 50% improvements in wastewater aeration efficiency,

increasing treatment capacity

Experience

Senior Environmental Engineer 2001-2010

Novozymes North America, Franklinton, North Carolina

Moving Bed Bioreactor Design and Installation: Designed and supervised

construction of a Moving Bed Bioreactor (MBBR), which was built by

converting an existing mechanical aeration basin. Project achieved greater

than 90% removal of soluble COD. Led project on budget from concept,

through design, permitting, procurement and installation in less than nine

months, in time for a 20% production capacity expansion.

Decanter-Centrifuge Installation: Managed project for installation of

decanter centrifuge. Work included facility design and layout, equipment

selection and procurement, managing and supervising contractors, and

writing permit modifications. Started system within a few months of final

permit approvals, producing biomass cake at planned capacity, and on

budget. Facilitated transfer of operations to production team.

Process Wastewater Aeration Improvements: Led investigation into process

wastewater aeration which resulted in 50% improvement in oxygen transfer

efficiency. Developed calculations to assess oxygen transfer efficiency

and aeration capacity. Facilitated oxygen transfer testing to determine

diffuser with lowest fouling potential and best performance. Identified

and developed cleaning procedures for diffusers.

Reduction of Total Dissolved Solids (TDS) in Wastewater Effluent: Led

cross-functional team to reduce TDS from 2500 to less than 1500 mg/L in

wastewater effluent through changes in production processes. Evaluated

impact of proposed production changes to allow team to focus on

opportunities with biggest impacts. Developed Excel spreadsheet model to

predict effluent TDS based on changes in production schedule and product

recipes.

Reverse Osmosis Investigation: Investigated Reverse Osmosis (RO) as

potential technology to further reduce TDS in wastewater effluent. Led

reverse osmosis experiments, scaling experimental results to full-scale

conceptual design. Developed cost model for implementation of technology.

Managed consultants investigating reverse osmosis and other options for

wastewater disposal.

Phosphorous Reduction Investigation: Conducted bench scale trials to

precipitate phosphorous from wastewater, using ferric chloride. Used bench

scale data to develop conceptual design and cost estimate for a full-scale

phosphorous precipitation installation to reduce phosphorous from 100 to 10

mg/L. Investigated reducing sources from production as alternate means for

phosphorous reduction.

Aquatic Toxicity Investigation: Conducted series of aquatic toxicity

studies to determine effect of a combined wastewater discharge with plant

process wastewater and municipal wastewater. Identified maximum amounts

which could be discharged without toxicity effects under the current

permitting structure.

Identification and Correction of Filamentous Bacteria: Identified growth

of filamentous bacteria as key issue related to poor settling in secondary

clarifier. Identified expertise within the company to help identify

predominant filaments and implement chlorination to control growth.

Addressed low food-to-mass ratio, the underlying cause for filamentous

growth. Implemented routine microexam procedures.

Wastewater Irrigation Modeling: Modeled wastewater irrigation system which

includes over seven miles of irrigation pipeline, over 900 acres of

irrigation fields and three different irrigation technologies, using Pipe-

Flo software. Recommended improvements to achieve higher annual irrigation

rates.

Recovery Process Engineer 1999-2001

Novozymes North America, Franklinton, North Carolina

Led team in development of conceptual design of customized product blending

system. Interfaced with engineers to ensure finished system met

requirements. Led project start-up, including process validation efforts.

Provided day-to-day support of production processes. Improved safety by

changing polymer make-up system. Investigated material corrosion issues.

Trained operators in recovery technology.

Research Engineer 1996-1999

Energy BioSystems Corporation, The Woodlands, Texas

Conducted research and engineering for a start-up company developing

biotechnology for desulfurization in petroleum refineries. Planned and

conducted experiments, related to reactor design, separations, and product

recovery. Designed and implemented an aqueous by-product recovery scheme at

the pilot plant scale, utilizing ultrafiltration and ion exchange.

Transferred technology from the laboratory to the pilot plant. Trained

pilot plant personnel to operate process. Conducted process simulations of

industrial scale biodesulfurization processes, using SuperPro Designer

software, which allowed technical and economic evaluation of the full scale

process. Wrote invention disclosures for potential patent applications.

Environmental Specialist 1993-1996

RMT/Jones & Neuse, Austin and Houston, Texas

Served as main client interface with several clients. Managed projects

involving environmental site assessments and hazardous waste permit

applications. Developed treatability studies and work-plans for

bioremediation of contaminated soils and sludge. Developed and evaluated

remediation alternatives for soil and groundwater contaminated with

inorganic and/or organic constituents. Evaluated the design and operation

of industrial wastewater treatment plants for organic and inorganic

contaminants. Prepared RCRA closure plans and corrective measures studies.

Conducted environmental compliance audits for hazardous waste, solid

waste, wastewater and stormwater compliance. Assisted industrial

facilities with development of Spill Prevention, Control and

Countermeasures (SPCC) plans, and Stormwater Pollution Prevention Plans

(SWP3). Worked extended assignment for an oil refinery in Texas City,

Texas. Assisted with Process Safety Management (PSM) tasks, including

hazardous operations (HAZOP) analyses and compliance audits.
