Reverse
osmosis systems are available as either "stand alone" or "turnkey"
units ranging in fresh water production capacity from 600 GPD to 50,000
GPD and up for bottling, water stores or other commercial or industrial
needs where good water purity is required.
Commercial
and industrial reverse osmosis systems can generally produce water in
the 2 to 10 mg/liter, numerically equivalent to parts per million (PPM)
TDS range, assuming incoming water TDS are under 1000 mg/liter.
Water quality
may vary depending on a variety of conditions, mainly membrane condition.
Production rates may vary depending on temperature, pressure, membrane
condition and other factors such as the amount of water "recycled"
within the reverse osmosis system as part of the filtration process.
Whether
600 or 50,000 gallons, commercial and industrial reverse osmosis systems
must incorporate several stages of preconditioning in order to transform
the incoming water into product water which meets various quality requirements.
The figure below illustrates these preconditioning stages.

PRECONDITIONERS
- A REQUIRED FIRST STEP
Preconditioning
normally consists of some type of multi-media or "depth" filter,
followed by a water conditioner or softener and finally by a carbon
filtration system to remove organic chemicals and chlorine which would
do major damage to the membrane if not removed.
A typical
pre conditioner is highlighted in red in
the picture below. The figure illustrates other system 
components,
including the reverse osmosis and disinfection(uv and ozone) modules
as noted in the block diagram above.
In many
cases, iron, bacteria, silicates or other contaminants may be present
in the incoming water and must be removed with additional
stages of preconditioning.
A complete
water analysis is required in order to fully specify the various components
which must precede the reverse osmosis module.
Failure
to properly pre treat the incoming water may result in premature and
catastrophic failure many of the system components. For example: if
iron is present, not only will the reverse osmosis membrane go belly
up but the water softener/conditioner's ability to soften the incoming
water will be compromised.

DISINFECTION
MODULE
All water
store and bottling operations will require some combination of Ultraviolet
and Ozone processing to ensure that biological purity of the product
water is maintained. Even in industrial applications, biological purity
can be critically important.
As the
water is produced by the reverse osmosis modules(described below) the
water is placed in a closed storage tank. To prevent stagnation and
possible biological contamination after production and prior to use
a combination recirculation and disinfection module is required.
A sample
of a smaller disinfection system running at 10 gallons per minute(recirculation
or water delivery) is illustrated below. It is an integral part of each
of the "turnkey" reverse osmosis systems illustrated in the
section below. For additional information on this item, including specifications
and pricing for systems capable of treating up to 60 gallons per minute,
GO HERE.

REVERSE
OSMOSIS MODULES
Most individuals
reading this section will be looking for one of three applications for
commercial or industrial reverse osmosis:
- Water
Store
- Bottling
or Bulk Water Delivery System
- Industrial
Water
Both water
store and bottling system applications will use pre conditioners as
well as disinfection modules as shown at the top of this page. Industrial
water users in most cases will need to add a de ionization module to
the basic configuration to produce water at higher purity levels such
as that need in semiconductor, electronics or medical water processes.
Purity
levels attainable by the basic reverse osmosis module will normally
fall short of these required high purity levels.
Reverse
osmosis modules for water stores will normally fall in the 600 to 3000
gallon per day range while bottling systems will range from 1500 to
25,000 gallons per day or higher.
Industrial
reverse osmosis water users may need 5 to 10 times these volumes, sometimes
reaching into several hundred thousand gallons per 24 hours, depending
on application.
Low Capacity Reverse Osmosis Modules for Entry Level Water Stores and
Small Water Bottling Operations
(no
preconditioning or disinfection capabilities)
.
Reverse
osmosis production rates of 600 to 3000 gallons per 24 hours for water
stores will normally encompass reverse osmosis modules of the types
illustrated above. Included in these modular designs are pumping and
filtration units, the reverse osmosis membranes and a wide variety of
controls and display items to monitor water flow rates, system operating
conditions and water quality.
The
units shown above can be installed where the customer desires to independently
obtain separate preconditioning and disinfection modules and "wire
together" his own complete operating system.
To
reduce maintenance and inter-module operational interface problems,
most water store(and bottling system) owners prefer to obtain a
fully integrated system, including all interconnections and inter-module
control units to permit the individual components to function more effectively
as a group than when there are designed as separate, individual modules.
Integrated
systems for water stores and bottling applications then will look like
the components illustrated in the figures below, with all components
"talking to each" other as will be required in any water store
or bottling application and packaged in a compact and convenient manner.
The reverse osmosis components are highlighted
in red in the figure below.

Medium
Capacity Reverse Osmosis Modules for Larger Water Stores, Bulk Water
Producers and Medium Size Water Bottling Operations
Bottled
and bulk water producers still require all of the components identified
at the top of this page. Just bigger and faster. Industrial users also
begin to become interested when capacities begin to enter the five and
six figure arena.
It
is important to remember that steam distillation systems are available
in volumes just short of 10,000 gallons per day and that many forward
looking bottling operations are beginning to add distilled water to
their venue, realizing that the distilled water "niche" market
is fast becoming one of the more financially lucrative in the bottled
water industry. For more information
on distillers in the 500 to 10,000 gallon range, GO HERE.
It
may come as a shock to some reading this page that there are some operational
water stores which have daily needs exceeding 20,000 US gallons.
For
those reading this page and contemplating a business whose needs are
in that range, a system specification
for a 24,000 GPD turnkey reverse osmosis system is given HERE.
Many
water stores have expanded to a lucrative bottled or bulk delivery business,
thereby creating a major step function in their daily water needs. Another
group of forward looking business entities are beginning to spring up
around the country where "bulk delivery" to both business
and industry is beginning to take hold. Route trucks carrying thousands
of gallons of purified water now deliver purified reverse osmosis and
steam distilled water in several states at this time.
As
the demand for bottled water increases and the public tires of the inconvenience
of 5 gallon water jugs rolling around their home and office, the financial
and physical attractiveness of bulk water delivery to both home and
office complexes begins to rattle cash registers in the water industry.
Larger
Revese Osmosis Systems for High Volume Applications.
The
electronics industry, offshore hotels, casinos, manufacturing facilities
and other construction projects are constantly in need of low cost,
high purity water either produced on site or delivered on a regular
basis.
A
classic example of where considerable cost savings can be demonstrated
in several industrial sectors is where these industries are currently
attempting to produce high purity process water by transforming highly
contaminated and mineral laden tap water directly into process water.
These
industries typically have a water service deliver(sometimes daily) a
new batch of regenerated mixed bed resin de ionization tanks.
Without
batting an eye, the plant manager pumps extremely dirty tap water directly
into these DI beds, rapidly exhausting the DI bed with the high mineral
content tap water.
The time variant performance of these DI beds looks just like a children's
water slide...it tails off to "un useable" in just a few hours
or days.
Smart
industry leaders, eager to cut recurring costs from a non-negotiable
portion of their business expenses(high purity process water), are finding
that "pre-processing" the incoming tap water to their plants
using high volume reverse osmosis(or even distillation system) dramatically
reduces their dependence(and associated costs) on the unending flow
of regenerated DI tanks.
Here's
a simple example. Suppose each DI tank has a total capacity of 10,000
grains(meaning that 10,000 grains of hardness can be removed before
the output water quality falls below a preset standard for that particular
industrial process.
Now
suppose that the incoming tap water has a total dissolved solids(TDS)
content of 500 milligrams per liter of hard minerals such as calcium
and magnesiuim. This is equivalent to 500grains divided by 17 milligrams/liter/grain
or 29 grains of hardness. Some might consider this number excessive
for water feeding an industrial complex but it is not hard to find numbers
that exceed even this level in various parts of the country.
Next
with 29 grains of hardness per gallon we divide that number into 10,000
gallons and we find that the capacity of the DI tank is roughly 345
gallons before the quality of output water begins to fall below acceptable
limits.
345
gallons is not that much water in an industrial process; infact it is
a drop in the bucket for most industrial concerns.
Now,
consider placing a turnkey reverse osmosis system ahead of a DI bed(as
shown at the top of the page and repeated below). The reverse osmosis
system reduces the 500 milligrams per liter of dissolved solids to a
number less than five(5) for example. This multplies the lifetime of
the DI tank by 100, thus providing 34500 gallons of process grade water
between DI tank regenerations. The water service now comes to exchange
the DI tank once every 35,000 gallons, not every 345 gallons.
If
your company currently uses a DI water service, ask your company accountant
to provide you with the monthly costs of the DI service. Find out
how many gallons you use per month, call us
at 1-800-478-7342 and we can provide you information on how
you can produce your own high purity process water and save tens if
not hundreds of thousands of dollars in yearly manufacturing and operating
expenses.
And
yes, we have the larger water processing modules to handle the really
big jobs.
