REVERSE
OSMOSIS AND ULTRAFILTRATION SYSTEMS
Remco
Engineering reverse osmosis systems fill a unique position in the
area of water and wastewater treatment. Our reverse osmosis systems
provide complete water purification solutions with microprocessor
control and fiberglass support skids for trouble free automatic
operation and a long useful life.
Our
systems use a recycle loop that takes part of the reject water from
the system and recycles it back to the holding tank that feeds the
reverse osmosis pump. This is possible because of the water softening
system we include with each system. This allows us to use 94%+ of
the water we receive into the system. Our competitors will reject
up to 50% of the water to drain to keep the membranes from fouling
with the water hardness. We remove the hardness first.
Systems
can be run with a softener or anti-scalant feed. No other chemicals
are required. . No expensive specialty chemicals that you can
forget to order and foul your membrane. . The carbon bed reacts
with the chlorine and has an almost infinite life. Only plugging
of the carbon would require its' replacement. The only periodic
maintenance is to change the prefilter to keep the flow rate at
an acceptable level.
Our
reverse osmosis systems are sized to handle from 1000gallons per
day to 500,000 gallons per day. Small reverse osmosis systems have
all components mounted on one skid. Larger systems have individual
tanks and a separate skid for the RO system.
Installation
is simply placing the skid in place, connecting power, city water
and the drain lines. Larger reverse osmosis systems will require
some simple interconnect plumbing from the feed tanks. In less than
4 hours, most all systems can be installed and running.
Each
Remco system includes:
- 5
micron prefiltration;
- High
flow carbon bed for chlorine removal with an automatic timed
backwash;
- Either
a two tank water softening system to remove water hardness
or an anti-scalant feed to sequester the calcium and mangesium.
- A
fiberglass skid constructed of epoxy bonded fiberglass structural
material with a control panel mounting surface and supports
for the reverse osmosis (RO) vessels;
- A
stainless steel multistage reverse osmosis pump;
-
PVC or Stainless Steel interconnection plumbing.
- Nema
4x (waterproof) fiberglass control panel;
- Fiberglass
reverse osmosis pressure vessels;
- Thin
Film composite reverse osmosis membranes with 97%, 99% or
99.5%rejection;
- Preprogrammed
microprocessor controller interfaced to all pumps and level
controls;
- Softened
water storage tank with level controls interfaced to the microprocessor
or metering pump for the anti-scalant feed;
- Reverse
osmosis water storage tank with level controls interfaced
to the microprocessor;
- Flowmeters
on permeate, reject, and recycle streams;
- Conductivity
meter on permeate stream;
- Valves
for adjusting recycle rate, pump output pressure, and backpressure;
- Ultraviolet
sterilizer on the permeate output; (optional)
-
up to 94%+ water usage efficiency due to the recycle loop
and water softening (94% of the water is permeate, 6% of the
water is dumped to drain)
- Optional
computer monitor and control system for data logging and remote
service and troublshooting
With
other systems, the base price is a stripped system and everything
useful is an extra cost option. We have very few options. Ours systems
are designed to run efficiently, continuously, and with minimum
down time. We don't like field service so if it broke, we changed
it for something that won't break. Each service call is money out
of our pocket so we won't sell you a system that needs lots of service.
We
design our systems to include both softening and carbon treatment
for removal of all hardness ions and chlorine. The hardness ions
foul the reverse osmosis membrane and require periodic cleaning
to remove them. If the reverse osmosis membranes become too fouled,
the membranes will need to be replaced. By removing the hardness
totally, we avoid periodic membrane cleaning totally. We have some
systems that are only cleaned on an annual basis. The chlorine removal
is to prevent oxidation of the membrane surface.
