New AWPCA column from ADEQ to debut soon.
Chuck Ohr, Industrial Pre-treatment Coordinator for ADEQ will be writing a regular
industrial
pretreatment column for the AWPCA Newsletter called "Upgradient" starting
in the July 2002 issue.
He hopes it will become a popular source of information and that the pretreatment
professionals will
turn to it first when they receive their newsletter.
Look for it in the July issue!
What is Pretreatment?
The National Pretreatment Program is a cooperative effort of federal, state, and
local regulatory environmental agencies established to protect water quality. The
program is designed to reduce the level of pollutants discharged by industry and
other non-domestic wastewater sources into municipal sewer systems, and thereby,
reduce the amount of pollutants released into the environment through wastewater.
The objectives of the program are to protect the Publicly Owned Treatment Works
(POTW) from pollutants that may interfere with plant operation, to prevent pollutants
that may pass through untreated from being introduced into the POTW, and to improve
opportunities for the POTW to reuse wastewater and sludges that are generated.
The term "pretreatment" refers to the requirement that nondomestic sources
discharging wastewater to POTWs control their discharges, and meet limits established
by EPA, the State or local authority on the amount of pollutants allowed to be discharged.
The control of the pollutants may necessitate treatment prior to discharge to the
POTW (therefore the term "pretreatment"). Limits may be met by the nondomestic
source through pollution prevention techniques (product substitution recycle and
reuse of materials) or treatment of the wastewater.
Program objectives are:
To prevent industrial facilities' pollutant discharges from passing through
municipal wastewater treatment plants untreated;
To protect treatment plants from the threat posed by untreated industrial wastewater,
including explosion, fire, and interference with the treatment process; and
To improve the quality of effluents and sludges so that they can be used for beneficial
purposes.
There are more than 1500 publicly owned treatment works that are required to implement
local Pretreatment programs. By reducing the level of pollutants discharged by industry
into municipal sewage systems, the program ensures the protection of America's
multi-billion dollar public investment in treatment infrastructure. .
