Presentation Abstract
Optimizing Surface Water Treatment - The use of chemicals
to treat water sources is oftentimes the highest annual cost associated with
maintaining a public drinking water supply system. Depending on source waters,
coagulation and flocculation can have the greatest impact on operation of
filters and maintaining a safe drinking water supply. Optimizing Surface Water
Treatment will focus on how operators can improve their water treatment and
distribution system.
The presentation of this seminar is based on experience, data, and application
of the principals of water treatment design, as standardized, in part, by AWWA
and the USEPA Office of Water. With a developed knowledge of the types of
coagulants and process aids available, the presentation will take a look at how
to evaluate potential improvements using relatively simple bench and pilot
testing techniques. Operators may use the techniques discussed to help optimize
chemical performance and potentially reduce chemical operating costs.
Experience has shown that the proper sequence of chemical injection, along with
the correct equipment can be related to lower chemical costs. Portions of the
presentation will also focus on how to implement a change in the treatment
process to incorporate a new chemical or different injection point. Using the
results from a Comprehensive Performance Evaluation (CPE) along with regular
facility monitoring, participants will learn about potential indicators that
reflect an overall improvement in operations.
Filter Surveillance - The presentation of this seminar is based upon the AWWA
sponsored workshop entitled "Filter Surveillance Techniques for Water Utilities"
which pertains to dual media gravity filters typically used to treat surface
water supplies. The filtering process is one of the most critical steps in the
treatment of raw water as it requires operator knowledge and "hands-on"
experience to provide safely treated water, which is in compliance with
increasingly stringent regulations. Filter operations and filter capabilities
both are vital to satisfying the treatment process goals and objectives. This
filter surveillance classroom presentation will discuss backwash evaluation
tests consisting of filter rise rates, boil test, backwash waste turbidity
profile, and filter bed expansion to aid the operator in conducting effective
and efficient backwashing. The mechanical elements of the filters (e.g. media,
underdrains, air scouring, etc…) will be discussed in relation to filter
bed/media tests consisting of filter coring, media sampling and inspections for
mudballs, media interface, and media depth. The two-day workshop sponsored by
AWWA is conducted at a treatment facility to enhance the presentation of
information and to provide "in the field" demonstrations. This 3-hour "overview
seminar" will consist only of classroom presented materials with examples and
illustrations of field demonstrations and applied practices.
Speakers
Brian L. Hackman, P.E.
Mr. Hackman has more than 8 years of experience in research and design of water
supply and treatment projects for both ground and surface water communities in
the Midwest. His experience includes the development of bench and pilot testing
protocols for State public water supply design approval, procurement
specification development for advanced drinking water treatment processes,
construction management and general observation, and first-of-its-kind
implementation, design, and start-up of membrane filtration and co-filtration
HMO facilities in Illinois and Kentucky. Over the years, Brian has been
responsible for the development of full-scale design criteria based from bench
and pilot scale studies for several green-field water treatment facilities. Mr.
Hackman has served on the National AWWA Membrane Filtration Research Committee
(1998-2000) and presented numerous papers on surface water treatment, regulatory
issues, and membrane filtration for various state AWWA chapters. Mr. Hackman
holds two degrees: B.S. in Civil Engineering, with honors, 1996 and M.S. of
Environmental Engineering in Civil Engineering, 1998, both from the University
of Illinois-Urbana. Brian is a licensed Professional Engineer in Illinois,
Wisconsin, and Kentucky.
S. John Calise, P.E.
Mr. Calise has more than 20 years of experience in the fields of water,
wastewater, and storm water infrastructure improvements. His experience includes
infrastructure improvement projects related to water and wastewater; facility
planning/feasibility reports; development of Capital Improvement Programs (CIP);
design and construction observation of water/wastewater treatment plants,
including costs estimates, and permitting. Various engineering work
responsibilities include hydraulic analysis using computer modeling; preparation
of construction documents; and preparation of permit requirements for municipal
utility projects involving water distribution/pumping/treatment facilities. Mr.
Calise has attended the two-day WTP Filter Surveillance Seminar sponsored by
AWWA. Mr. Calise holds two degrees: B.S. Civil Engineering, University of
Missouri at Rolla, 1979 and M.S. Hydraulics/Hydrology, University of Missouri at
Rolla, 1981. He is licensed as a Professional Engineer in Florida, Illinois and
Missouri.
Ed J. DeGroot
Mr. DeGroot has more than 30 years of experience in environmental work. He has
served as supervising designer, project manager, and construction observer for
numerous potable water and wastewater projects including design, construction
observation, and start-up of several new water treatment plants, renovations of
existing water treatment plants, wells and water distribution systems. He has
attended the two-day WTP Filter Surveillance Seminar sponsored by AWWA and
assisted several communities in conducting/evaluating their filter needs. He
holds a Class A Illinois Public Water Supply Operators license.
