Wastewater
Treatment

Tim Hanna, PRAB

These systems provide the versatility you need to effectively treat wastewater.
WASTEWATER TREATMENT HAS
become an increasingly critical part of plant
operations over the past decade, and manufacturing companies in all industrial sectors
are prioritizing the reduction of water
consumption. Compliance with ever-tightening federal regulations for wastewater
treatment, handling, and disposal requires
finishing-industry executives to focus on
the issue. Additional motivating factors for
recycling wastewater include strengthening
a company's public image, improving the
overall work environment, boosting
employee morale, and adhering to ISO
14001 initiatives.

The ultimate motivator is almost always
related to cost. From a strictly monetary
standpoint, it makes complete sense for
finishing shops to adopt a formal wastewater treatment and reuse policy, as it allows
them to dramatically cut rising operational
costs while increasing profitability. Most
of the hazardous waste in surface finishing
comes from wastewater that is generated by
rinse water.
The obvious goal should always be to
recycle wastewater internally. This will
increase equipment life, improve product
quality, reduce maintenance, and prolong
the usage of working fluids. Implementing

a treatment system means, when the time
comes to dispose of wastewater, finishing
shops can virtually eliminate the volume for
disposal or haul-away.

TREATMENT EQUIPMENT
At the heart of any system is the equipment. There are several options available,
each designed to perform specific types of
treatment and deliver a quick return on
investment (ROI).
Ultrafiltration (UF) systems: The
concentration and chemical form of the
soluble heavy metals in a wastewater stream
varies, depending on the industry and the
