Industrial water treatment
Commercial water treatment
Domestic water treatment

Industrial RO systems:

Industrial
RO systems are perfect RO systems with high-performance and capability.
These systems are produced with different flow rate for water
treatment.

Because
these units use RO technology, they are also capable of removing
dissolved inorganic materials, organic substances, dissolved and
microbiological contaminants.

RO technology:

Reverse
Osmosis is a special filter that normally causes water to move from low
solute concentration (low or no salt) into a high solute concentration
(high salt). In Water purification system, with the help of pump
pressure, water moves from (high salt) to (low salt) part. This causes
the separation of pure water from impure water, which is called water
purification

RO components:

Membrane is the filter of Reverse osmosis and actually is the heart of the system.

Pump creates a force in order to push water from low solute concentration into a high solute concentration.

Pre-filter:

Due
to the sensitivity of the membrane to suspended particulates such as
chlorine, iron and so on in impure water, it is necessary to remove them
before they catch the membrane. Therefore, water is passed through
Pre-filter which is mainly PP and carbon.

Function of system pre-filter

Pre-filtration:

Pre-filtration
is a pre-treatment process to keep the heart of system (membrane)
healthy. This process often consists of three stages which prepares the
raw water to enter the main unit device (membrane). It removes harmful
materials, particularly chlorine. Chlorine is a very important factor in
reducing membrane performance and its lifetime.

First
stage: PP fiber filter: This filter is made of 5 microns 100% pure
pressed polypropylene. It removes mud, sand and other suspended
contaminants.

Tissue
structure of PP filter of system is so that larger particles are placed
in the outer parts and finer particles are trapped in the inner parts.
In other words, the density of filter fiber becomes more intensive from
the outer surface to the inner surface. The Tissue structure of these
filters leads to optimization of performance and increasing of Filter
lifetime.

Second and third stages: The granular carbon filter and solid carbon

Activated
carbon is produced from carbon materials such as wood, coal, petroleum
residues and so on. Coal is prepared by burning of material in an
airless space. This coal is then oxidized at higher temperatures to find
a highly porous structure. The activation phase creates irregular
channels and pores in solid mass, leading to a very high ratio of
surface area to mass (500 to 1500). The activated carbon power is based
to these channels and pores. Activated carbon is used for the removal of
taste, odor, color, organic materials, Haloform, phenolic materials and
chlorine.

Second
stage: Granular Activated Carbon Filter, it is composed of granular
particles (sand-like) of activated carbon. It is used for the primary
removal of taste, odor, color, organic materials, Haloform, phenolic
materials, chlorine and organic chemicals found in insecticides and
pesticides from water.

Third
stage: Carbon Block filter, It is used to complete the second stage and
to remove the chemicals in water. Porous structure of the filter is
considered to remove the highest level of Chlorine and toxins. The
filter consists of two layers of polypropylene for the pre-treatment.

Housing
(Tank) of 1, 2 and 3 filters are made of polycarbonate. They are
sanitary, anti-scratch, anti-blurring are resistant to cracking.

When to Replace Filter?

Depending
on the quality of the water, stage 1 filter is replaced over 3 to 6
months and stages 2 & 3 filters are replaced over 6 to 12 months.

Membrane: If pretreatment filters are replaced on time, they will work effectively for 2 years.

Advantages of Reverse Osmosis:

High throughput water purification

Easy to use and operate

Possibility of designing for different flow rates of water

Small size, compared to other filtration systems

Ability to remove minerals of water: anion and cation (Without a noticeable effect on water taste)

Good performance in many range of amount of water minerals

More Suitable and beautiful appearance than other systems

RO system operating tips:

Wastewater (condensed water) outlet should never be blocked.

No valve should be installed on purified water outlet line. Never block the way and do not put it under pressure.

If you need to transfer the treated water to a higher elevation, you may use a storage tank and a pump separately.

Prevent entering chlorine to your system by using carbon filter and on time replacement

You must replace pre-filters on time.

Control and record input and output TDS and waste water every day.

Reverse
osmosis water filtration system reduces water pH a little. Low pH makes
the water bitter. In case of the above problem, use a mix valve to mix
some inlet water with the purified water.

It is recommended to use the anti Escalante to increase membrane lifetime and performance of the device.
