graph, control and/or make program changes to your system in a
matter of minutes. We can monitor your operation of the system
and make suggestions as to maintenance intervals, cleaning cycles,
etc. as required. This insures that you are not alone once you
purchase a system from us, we are still active in the operation
of your system!
We provide services
and products to:
and Control processes
waste water treatment costs,
Recycle water, ,
improve rinsing efficiency.
We can supply influent
water systems, design a full wet process area to reduce water
usage and minimize waste water treatment costs (both capital and
operating), and we can provide you the pieces to do it yourself.
We do this by paying attention to water usage and designing equipment
to fit the problem. We are not marketing products, just solutions.
Our equipment has evolved to fit a variety of situations and facility
sizes which require intelligent solutions. The solutions we have
developed and products we have available include:
Automation monitoring and control - SCADA
and Cooling Tower Water Treatment
Ion Exchange metal removal and recovery systems;
Waste Water Treatment for Printed Circuit Manufactures
Reverse Osmosis systems
Deionization and water softening systems;
Scrubber/Deburrer recirculation Systems
Final filter effluent polishing systems
Rinse water control systems
pH/ORP and Conductivity controllers and/or recording systems ( Nema
Point Source Ion Exchange Systems
Simplex Regeneration Modules for Ion Exchange Resins
Gas Contacting/Scrubbing Systems
Gold Recovery Systems
(Supervisory Control and Data Acquisition) + HMI (Human Machine
Interface) = CCC (Control, Cost reduction and Confidence)
CCC systems use real-time data acquisition and trending to allow
you to see what is happening with your business, as it happens.
Any process can be automated and monitored by these systems. Pioneered
in the chemical and petrochemical industries, new hardware and software
now allow these systems to be used for everyday processes. This
results in cost savings that pay for a system in a few months.
METAL RECOVERY ION EXCHANGE SYSTEMS
Our state of the art systems use resins specifically designated to
provide high metal holding capacity and low regeneration costs.
Elution (removal) of the metal is followed by electrowinning or
recycling of the metal salt. We can provide a single system for
all rinses or small separate systems for each metal if rinse water
lines are segregated. Our microprocessor control system automates
the backwash/reclaim cycle. Three types of systems are available,
the Metal Recovery Ion Exchange(MRIX) for large, end of the pipe
streams, the Basic Ion Exchange (BIX) system for a modular and
lower cost approach, and the Point Source Ion Exchange(P-SIX)(TM)
for point source metal removal (see below). Our Power Purge
regeneration system is the most efficient (See
graph) in the industry providing the highest concentration
of metal in the smallest volume of regenerant.
REVERSE OSMOSIS SYSTEMS
Where Total Dissolved Solids (TDS) is high (over 500 PPM) or clean
waste water is to be recycled, Reverse Osmosis (RO) is usually
the best technology. Reverse osmosis is used on incoming water
before deionization (DI) to reduce overall loading on the DI system,
the DI system can last 25 times longer between regeneration or
bottle changes. For wastewater treatment application, reverse
osmosis is used after extensive filtration or after Metal Recover Ion Exchange (MRIX) systems. With the proper
pretreatment and filtration, up to 90% of the water entering the
system can be purified. Send for our reverse osmosis literature
for more information.
(DEIONIZATION) AND WATER RECYCLING SYSTEMS
can save you money or cost you money. It sounds like a great idea
but the hidden costs can be a drain on your resources. A properly
designed system will insure that you get low operating costs.
Our recycling systems can be either point source deionization
resin systems, large scale deionization, or reverse osmosis polishing
after ion exchange metal recovery. Each is perfect for a particular
situation but none is perfect for all. Ask for the recycling applications
bulletin. Please read treatment and recycling
strategies for printed circuit manufacturers and water
recycling costs for more information.
DUPLEX POLISHING FILTERS
Dual medial filters sized for 20-200 gpm use two back-washable filters
where one is on line all of the time. A microprocessor controller
monitors and automatically backwashes each filter. One is always
on line. If water flow increases, the system automatically increases
the filtration rate until the flow comes back to equilibrium.
Flow and pH logging and pH adjust are options.
If you have problems
with your clarifier or other pretreatment system, a duplex polishing
filter may be the perfect solution. These system are capable of
taking a 20 NTU water source and cleaning it to a 0.2 output.
We have installed these in metal finishing shops with excellent
SCRUBBER RECIRCULATION/FILTRATION SYSTEM (CSRS)
Using a cyclone to remove metal fines is not new but following that
with duplex polishing filters is. The system automatically backwashes
the polishing filters when needed and switches smoothly to the
clean filter when necessary. Self cleaning and efficient in a
36" x 54" floor space. We have multiple installations
around the country and even have a triple counterflow module for
a pumice scrubber. We have built a version of this product that
includes a full metal ion exchange system with regeneration.
SIMPLEX ION EXCHANGE RESIN REGENERATION SYSTEMS
Remco Engineering offers a compact, wall mounted, microprocessor
controlled regeneration system for regenerating ion exchange columns.
The simplex regeneration modules are designed to regenerate anion,
cation and chelated resins according to manufacturers specifications.
These systems feature fully automated regeneration cycles with
resettable timing cycles.
POINT SOURCE RECYCLING - ION EXCHANGE AND PLATE OUT UNITS
Reducing water flow allows for down-sizing of equipment and a reduction
in capital outlay and operating costs. Reduced flow rates result
in increases metal content of the effluent. The easiest way to
treat metal bearing wastewater is to remove the metal at the source.
We have an in tank plateout unit (P-SER) that will remove the
metal from your dragout tanks. The plating unit mounts in the
tank and has a NEMA 4 enclosed rectifier on the outside of the
The P-SIX(TM) ion
exchange modules mount next to a rinse or at the end of a line.
Using small ion exchange columns sized and designed for a specific
metal, we can recover metals with a final discharge of less than
0.1 ppm. Using an electrolytic recovery module to recover the
metal provides a non-sludging system. A skid mounted regeneration
module regenerates tanks up to 5 cu. feet. It will regenerate
both Metal Recovery Ion Exchange(MRIX)and Deionization (DI) type
systems and is perfect for small closed loop systems using metal
recover and deionization ion exchange. Deionization is great but
regeneration is difficult. We have the ONLY automatic regeneration
system available as a standard product. Choose from our P-SIX ™ or our SIMPLEX ™ units
GOLD RECOVERY UNITS
We have manufactured a wide variety of gold recover/cyanide destruct
units. We have a 20 gpm RO based unit that concentrates a rinse
for plateout/resin stripping and cyanide destruct. We also have
built unit that treats batch dumps of gold dragouts and electrowinns
most of the gold, resin strips the remainder and treats the solution
for cyanide. We have developed a small, compact ion exchange system
for gold rinses which utilizes a double containment tank which
prevents loss of gold should a line break. The system is cost
effective and can reduce your gold down the drain to a couple
of parts per billion.
Ion exchange for
water softening and deionized water rinsing makes sense as the
product will rinse better and the hardness will be removed. Cleaners
will clean better and will rinse better. The better the rinsing
the less likely it is that process solutions will be carried down
the line from dragout. Usually DI is best provided by a service
rather than as an in-house system. A simple water softener for
removing hardness will greatly improve water quality. In conjunction
with a water reduction program and multiple rinse stations, the
cost savings and benefits are dramatic. If water hardness is less
then 75 parts per million, a deionization unit is cost effective.
Over 75 parts per million, a reverse osmosis system is usually
the better choice.
Water control for individual tanks, conveyor spray rinses or for
the whole shop can reduce daily consumption by 90% or more when
used with other techniques for rinse enhancement. Our point
source rinse water add-on timers and shop microprocessor controlled
rinse stations make rinsewater and control automatic. When there
is no work in progress, there is no water usage, it is that simple.
Our conveyor spray rinse timers have automatic
board detection and dual time delays to optimize water use.
The sumpless pump
is another unique product designed to ease your capital outlay.
Instead of digging a pit in the ground and lining it, we actually
suck the drain lines dry using a partial vacuum. The system can
also be used for emptying tanks for batch treating. It is designed
to adjust pH on the fly so a batch treating cycle is a one button
operation. pH adjust from rinses is also adjusted on the fly.
Many of our smaller metal exchange recovery units have built in
eductors so the customer doesn't have to add a new sump.
