Fenton's Reagent Application for Phenols Treatment
This specialty chemical manufacturer was experiencing discharge
violations (phenols, bio-toxicity) resulting from ineffective treatment
with their existing processes and needed to pre-treat a wastewater
stream to reduce phenols by 90% prior to mixing with higher flow waste
streams.
USP Technologies was tasked to design and provide a Fenton's treatment program
whereby the iron catalyst is added to the wastewater stream in-line
(static mixer), with the hydrogen peroxide injected (with mixing) into
the first cell of a baffled reaction vessel. The baffled reaction vessel
helps eliminate short-circuiting and provides sufficient reaction time.
The hydrogen peroxide and iron catalyst dosing modules are interlocked
with the wastewater pumps to ensure chemical feed stops with an
interruption in wastewater flow.
USP personnel worked
with a major environmental consulting firm and the manufacturer on lab
scale “treatability” tests as well as design of the full-scale process.
USP also conducted a successful 6-month full-scale demonstration
of the technology resulting in optimization of chemical dose
requirements.
USP supplies the iron catalyst, hydrogen
peroxide, and turnkey storage and dosing systems for both chemicals.
Supply scope includes ongoing equipment maintenance, remote tank
monitoring/inventory management, and applications services. The Fenton's
process is now a permanent part of the overall facility wastewater
treatment process and has consistently achieved >90% removal of
phenols from this stream as well as eliminated bio-toxicity violations
and public relations issues.
