PLATING AND ANODIZING: WASTEWATER MANAGEMENT
MANAGING WATER DISPOSAL
M
ost manufacturing operations need quantities of
water at various stages of the production cycle.
Plating and anodizing plants are no exception. And
of course, what they emit after the manufacturing
process is rarely something to which anybody wants to be exposed.
Wastewater management
is therefore simply a business
expense in today's world, and the better a plant's treatment
system, the fewer regulatory problems it is likely to face.
Critical factors to look at when you assess a wastewater system
are the plant's current throughput; how it might grow in the
foreseeable future; and what will deliver the most energy-efficient
results.
Kontek has made fully automated self-regenerating ion
exchange industrial wastewater recovery systems since 1980. Its
ReKon ion exchange systems remove dissolved heavy metals and
salts from wastewater and produce de-ionized water for recycling,
and the company says it can help metals finishers come closer to
achieving a Zero Liquid Discharge facility (ZLD).
" Our conventional wastewater treatment systems use chemical
precipitation to remove contaminants consistently, " the company
says. " These heavy metal physical chemical precipitation
systems require pH and/or ORP adjustment, then the addition
of coagulants and polymer, followed by solids separation and
solids removal/dewatering. The procedure can be performed on a
continuous flow or a batch treatment basis. "
It offers automatic batch treatment for large batch volumes
with different wastewater constituents. Treatments contain
pre-programmed chemical recipes designed to guarantee that
each different wastewater sources will
receive its specific
treatment formula, and consistently meet discharge compliance
requirements.
The systems offer analytics and data logging and constant
probe supervision. The pumping stations have both service
and standby modes, and there are neutralization reactors that
maintain pH levels.
Kontek systems use a continuous precipitation process
to treat wastewater before re-use or safe environmental
discharge. Users, the company says, benefit from lower
operating and maintenance costs with these systems.
It will also run smoothly with minimal operator
intervention.
The 1200 Series model is suited to small spaces in preexisting
facilities, and handles flow rates of up to 40 US
gallons pm. The larger 1300 Series can accommodate up
to four chemical reagent feed stations and 12 chemical
feed metering pumps, allowing multiple contaminants to
be treated simultaneously.
The 1400 Series, is a large, heavy duty system
engineered to treat water flows from 50 to 1,000 US gallons
pm. It has high-volume incline laminar flow clarifiers with
polyvinyl chloride plates to effectively extract remaining
waste particles. If the water does not meet compliance
parameters post-clarification, it is automatically re-treated until
ready for industrial re-use or draining.
Kontek's Rekon Ion Exchange System has roots in the
company's 40 years of experience in industrial water filtration.
The system produces high-purity de-ionized water for recycling
back to process rinse tanks, enhancing rinsing quality.
Company customers use Rekon technology for a wide variety
of applications, including raw water purification, softening and
deionization, wastewater treatment, wastewater recovery and
recycling, and polishing and targeted ion recovery. The system can
deliver recovery of 100 per cent of process rinse water.
Standard system design flow rates range from 10 to 600 gallons
pm. Standard UV sterilization systems control biofilm organic
growth, and co-current or counter-current regeneration cycles
are available.
" Ion exchange technology removes all heavy metals and salts
to produce purified deionized water for re-use, " Kontek says. " And
onboard resin cleaning systems ensure the longest resin life in the
industry. "
Penguin Filter Pump Industries offers a complete range of
filtration systems. Its Series A filter system, the company says,
is versatile and easy to install since both the pump and filter
chamber are independent units.
" The Penguin P series pump can be mounted anywhere along
the tank lip, " the company states. " Only the filter chamber needs to
be floor-mounted, thus Series A filter systems require minimum
floor space. "
These systems are recommended for all precious metal plating
baths, electroless nickel, and copper, as well as many acid and
alkaline solutions. Series A filter systems are reportedly easy to
clean, and filter cartridge replacement is simple.
" The easy-grip handles require no tools to release the filter
chamber head, " the company states. " Unscrew the tube nuts and
simply replace the filter cartridge. "
