3. What is Water Heart filtering system?
• It is industrial version of water filtering system for Pakistani market.
• Water Heart filtering system adjust the customer’s requirement of out put
water quality.
• For instance, if the input water is seawater, it is more than 35,000tds salty
water. Water Heart filtering system was designed to reduce its tds level up
to drinkable level (under 100) and Ph around 7.0.
• The case of industrial purpose, tds level is under 1,000. Water Heart
filtering system has high quality RO filter with NF, MF and carbon filter.
Therefore, it fits for industrial usage with low investment.
• For ultra high quality water for hospital, chemical industry purpose, Water
Heart adjust anti hydrogen ceramic filter and creates less than minus
200mV.
• This is a extra high quality water for human healthcare and medical
treatment purpose.
• Thus, DTS design any customers request of out put water quality by the
latest water filtering technology from Japan, USA and other overseas.

6. RO Filter
• Reverse osmosis (RO) is a water purification technology that uses
a semipermeable membrane. This membrane technology is not
properly a filtration method. In reverse osmosis, an applied
pressure is used to overcome osmotic pressure, a colligative
property, that is driven by chemical potential, a thermodynamic
parameter. Reverse osmosis can remove many types of
molecules and ions from solutions, and is used in both industrial
processes and the production of potable water. The result is that
the solute is retained on the pressurized side of the membrane
and the pure solvent is allowed to pass to the other side. To be
"selective", this membrane should not allow large molecules or
ions through the pores (holes), but should allow smaller
components of the solution (such as the solvent) to pass freely.
Reverse osmosis is most commonly known for its use in drinking
water purification from seawater, removing the salt and other
effluent materials from the water molecules.
7. Drinking water purification
Around the world, household drinking water purification systems, including a
reverse osmosis step, are commonly used for improving water for
drinking and cooking. Such systems typically include a number of steps:
1. a sediment filter to trap particles, including rust and calcium carbonate
2. optionally, a second sediment filter with smaller pores
3. an activated carbon filter to trap organic chemicals and chlorine, which
will attack and degrade thin film composite membrane reverse osmosis
membranes
4. a reverse osmosis filter, which is a thin film composite membrane (Thin
Film Composite or Thin Film Membrane)
5. optionally, a second carbon filter to capture those chemicals not removed
by the reverse osmosis membrane
6. optionally an ultraviolet lamp for sterilizing any microbes that may escape
filtering by the reverse osmosis membrane
7. latest developments in the sphere include nano materials and
membranes
8. Water and wastewater purification
• Reverse osmosis removes minerals from boiler water at power plants. The water is
distilled multiple times. It must be as pure as possible so it does not leave deposits on
the machinery or cause corrosion. The deposits inside or outside the boiler tubes may
result in underperformance of the boiler, bringing down its efficiency and resulting in
poor steam production, hence poor power production at the turbine.
• It is also used to clean effluent and brackish groundwater. The effluent in larger
volumes (more than 500 m3/d) should be treated in an effluent treatment plant first,
and then the clear effluent is subjected to reverse osmosis system. Treatment cost is
reduced significantly and membrane life of the reverse osmosis system is increased.
• The process of reverse osmosis can be used for the production of deionized water.
• Reverse osmosis process for water purification does not require thermal energy. Flow-
through reverse osmosis systems can be regulated by high-pressure pumps. The
recovery of purified water depends upon various factors, including membrane sizes,
membrane pore size, temperature, operating pressure, and membrane surface area.
9. Desalination
• Sea water reverse osmosis (SWRO) desalination, a membrane process, has
been commercially used since the early 1970s. Its first practical use was
demonstrated by Sidney Loeb from University of California at Los Angeles in
Coalinga, California, and Srinivasa Sourirajan of National Research council,
Canada. Because no heating or phase changes are needed, energy
requirements are low, around 3 kWh/m3, in comparison to other processes
of desalination, but are still much higher than those required for other forms
of water supply, including reverse osmosis treatment of wastewater, at 0.1 to
1 kWh/m3. Up to 50% of the seawater input can be recovered as fresh water,
though lower recoveries may reduce membrane fouling and energy
consumption.
• Brackish water reverse osmosis refers to desalination of water with a lower
salt content than sea water, usually from river estuaries or saline wells. The
process is substantially the same as sea water reverse osmosis, but requires
lower pressures and therefore less energy. Up to 80% of the feed water input
can be recovered as fresh water, depending on feed salinity.
10. System configuration
The typical single-pass sea water reverse osmosis system consists of:
1. Intake
2. Pretreatment
3. High pressure pump (if not combined with energy recovery)
4. Membrane assembly
5. Energy recovery (if used)
6. Remineralisation and pH adjustment
7. Disinfection
8. Alarm/control panel
11. Pretreatment
Pretreatment is important when working with reverse osmosis and
nanofiltration membranes due to the nature of their spiral-
wound design. The material is engineered in such a fashion as to
allow only one-way flow through the system. As such, the spiral-
wound design does not allow for backpulsing with water or air
agitation to scour its surface and remove solids. Since
accumulated material cannot be removed from the membrane
surface systems, they are highly susceptible to fouling (loss of
production capacity). Therefore, pretreatment is a necessity for
any reverse osmosis or nanofiltration system. Pretreatment in
sea water reverse osmosis systems has four major components:
12. Pretreatment
Pretreatment in sea water reverse osmosis systems has three major
components:
1) Dosing: Oxidizing biocides, such as chlorine, are added to kill
bacteria, followed by bisulfite dosing to deactivate the chlorine,
which can destroy a thin-film composite membrane. There are
also biofouling inhibitors, which do not kill bacteria, but simply
prevent them from growing slime on the membrane surface
and plant walls.
2) Prefiltration pH adjustment: If the pH, hardness and the alkalinity
in the feedwater result in a scaling tendency when they are
concentrated in the reject stream, acid is dosed to maintain
carbonates in their soluble carbonic acid form.
CO32– + H3O+ = HCO3– + H2O
HCO3– + H3O+ = H2CO3 + H2O
13. Pretreatment
3) Prefiltration antiscalants: Scale inhibitors (also known as antiscalants)
prevent formation of all scales compared to acid, which can only prevent
formation of calcium carbonate and calcium phosphate scales. In addition to
inhibiting carbonate and phosphate scales, antiscalants inhibit sulfate and
fluoride scales and disperse colloids and metal oxides.
Some small scale desalination units use 'beach wells'; they are usually drilled on
the seashore in close vicinity to the ocean. These intake facilities are
relatively simple to build and the seawater they collect is pretreated via slow
filtration through the subsurface sand/seabed formations in the area of
source water extraction. Raw seawater collected using beach wells is often
of better quality in terms of solids, silt, oil and grease, natural organic
contamination and aquatic microorganisms, compared to open seawater
intakes. Sometimes, beach intakes may also yield source water of lower
salinity.
14. High pressure pump
The high pressure pump supplies the pressure needed
to push water through the membrane, even as the
membrane rejects the passage of salt through it.
Typical pressures for brackish water range from 225 to
375 psi (15.5 to 26 bar, or 1.6 to 2.6 MPa). In the case
of seawater, they range from 800 to 1,180 psi (55 to
81.5 bar or 6 to 8 MPa). This requires a large amount
of energy. Where energy recovery is used, all or part of
the high pressure pump's work is done by the energy
recovery device, reducing the system energy input.
15. Membrane assembly
The layers of a membrane
The membrane assembly consists of a pressure vessel with a membrane that allows
feedwater to be pressed against it. The membrane must be strong enough to
withstand whatever pressure is applied against it. Reverse osmosis membranes are
made in a variety of configurations, with the two most common configurations being
spiral-wound and hollow-fiber.
Only a part of the saline feed water pumped into the membrane assembly passes through
the membrane with the salt removed. The remaining "concentrate" flow passes
along the saline side of the membrane to flush away the concentrated salt solution.
The percentage of desalinated water produced versus the saline water feed flow is
known as the "recovery ratio". This varies with the salinity of the feed water and the
system design parameters: typically 20% for small seawater systems, 40% for larger
seawater systems, and 80% for brackish water. The concentrate flow is at typically
only 3 bar / 50 psi less than the feed pressure, and thus still carries much of the high
pressure pump input energy.
The desalinated water purity is a function of the system design. Higher purity needs more
equipment and more energy. Purity expressed as total dissolved solids typically varies
from 100 to 400 parts per million (ppm or milligram/litre). A level of 500 ppm is
generally accepted as the upper limit for drinking water, while the US Food and Drug
Administration classifies mineral water as water containing at least 250 ppm.
16. Energy recovery
Energy recovery can reduce energy consumption by 50% or more. Much of the
high pressure pump input energy can be recovered from the concentrate
flow, and the increasing efficiency of energy recovery devices has greatly
reduced the energy needs of reverse osmosis desalination. Devices used, in
order of invention, are:
Turbine or Pelton wheel: a water turbine driven by the concentrate flow,
connected to the high pressure pump drive shaft to provide part of its input
power. Positive displacement axial piston motors have also been used in
place of turbines on smaller systems.
Turbocharger: a water turbine driven by the concentrate flow, directly connected
to a centrifugal pump which boosts the high pressure pump output pressure,
reducing the pressure needed from the high pressure pump and thereby its
energy input, similar in construction principle to car engine turbochargers.
