Chicago to host WEFTEC 2013
WEFTEC® — which will be held Oct. 5–9 in Chicago — is known for being the largest North American event of its kind. It draws more than 17,000 attendees each year. This year’s technical program will be one of the most comprehensive ever, offering 26 hands-on workshops, more than 140 sessions, and 10 facility tours. The exhibition will feature an estimated 1000 companies occupying more than 27,870 m2 (300,000 ft2) of space on the show floor. This year’s WEFTEC also features a number of new and enhanced events.

2007, the City of Greensboro, N.C., began a project to add a second fluid-bed
wastewater residual incinerator at its T.Z. Osborne Water Reclamation Facility.
The project would provide the capacity to handle an additional 59 dry Mg/d (65
dry ton/d) of primary solids — the existing fluid-bed incinerator can handle 54
dry Mg/d (60 dry ton/d) — and to replace the existing fluid bed during

purpose of preliminary treatment systems is to remove debris and grit from
influent and protect downstream processes from these damaging materials. While
screening devices remove debris, grit-removal processes remove smaller grit
particles. Grit particles that accumulate and concentrate at the bottom of a
grit-removal system are commonly referred to as “grit slurry.”
a process that is intended to prevent or reduce downstream maintenance often is
plagued with maintenance issues. Frequent problems include plugged grit-slurry
collection sumps, plugged grit-slurry piping, failed grit-slurry pumps, and
plugged grit-slurry concentrators.

Grains of knowledge
the outset of any project, someone is likely to say “First things first!” and
then suggest where to begin. At a water resource recovery facility (WRRF), the
first thing that happens to influent (usually) is screening and grit removal;
yet rarely is grit and its effect on the overall treatment process considered
October issue has two feature articles that put grit in the proper perspective.
The first focuses on analyzing the grit entering a facility. Grit
characterization and performance testing, if conducted properly, enable
professionals to determine how much grit is there — and more importantly — how
it will behave. This information can help designers, owners, and operators
better understand their challenges and arrive at effective solutions.
