UF PLANT (SOLAR UF SYSTEM):
As Solar operated drinking water system manufacturer, the Solar-powered
Reverse Osmosis Plant is considered the most efficient, due to its low
specific energy consumption (2~5 kWh /m3 ) while having the largest
desalination installation capacities.
HOW UF PLANT WORKS?
In Solar-powered Reverse Osmosis Plant or RO PLANT and UF
Plants, water is fed to the membrane with high pressure to overcome the
osmotic pressure of the feed water. Freshwater is collected at the
permeate side while the concentrated brine is removed in the Solar
Powered RO Plant. Feed pressure of solar powered RO systems
conventionally ranges from 6~8 MPa for seawater applications and
0.6~3MPa for brackish water applications.The productivity
and recovery ratio of solar RO system or in UF system is mainly affected
by the properties of the used membrane, the salinity of feed water,
feed pressure and feed flow rate, etc. The well-structured energy
recovery devices in modern RO/UF plants contributed significantly to the
high energy efficiency of the process. Vast research has been conducted
in terms of solar-driven RO desalination systems and Ultra Filtration
System. When combined with solar energy, RO or UF can be either run by
electrical power that is generated by photovoltaic (PV) cells or solar
thermal power plants, or by mechanical power that is produced from solar
thermal energy by a thermodynamic cycle. Additionally, as suppliers of
solar water treatment plants, our key priority have always been to fully
understand client demands and offer the finest solutions to
consistently and economically meet those needs.
REVERSE OSMOSIS IN UF POWERED WATER PLANTS:
In a PV-based RO system, PV and RO subsystems work isolatedly. Since
both of them are highly commercialized technologies, the technical
feasibility of the PV-RO plant is not much of an issue compared to its
economic feasibility and reliability.
Solar thermal driven RO systems or solar powered reverse osmosis, are
based on the organic Rankine cycle technology which is typically adopted
in solar thermal power generation systems. The ORC is a thermodynamic
power cycle consisting of organic working fluid and converts the thermal
energy input to the output mechanical energy. An ORC normally consists
of a pressure pump, evaporator, turbine, and condenser. The organic
working fluid is pressurized and inserted into the evaporator where it
is ignited to evaporate by heat exchange with high-temperature fluid.
And then the vapor expands through a turbine to produce mechanical work
to run the high-pressure pump for RO. At the same time, the feed saline
water could be preheated in the ORC condenser to increase the RO
membrane permeability.
ADVANTAGES OF UF WATER TREATMENT PLANTS:
a. Self-Contained Operation.
b. Portable for Water Treatment in Remote Location.
c. Highly Efficient and Economical.
d. Conservatively Designed for Reliable and long term Performance.
e. Factory tested to ensure trouble-free operation.
A solar operated WTP, water treatment
plants, is a facility that uses solar energy to treat drinking water,
sewage, reverse osmosis (RO) water, small effluent treatment plants
(ETP), and other types of water.
A solar
operated WTP works by using solar energy to power the treatment
processes, such as filtration, disinfection, and reverse osmosis. The
solar panels generate electricity, which is used to operate the pumps,
motors, and other equipment needed to treat the water.
The
benefits of a solar operated water treatment plant include reduced
energy costs, decreased carbon emissions, increased independence from
the power grid, and improved access to clean water in remote areas.
There
are several types of solar operated water treatment plants, including
solar powered RO plants, solar powered ETP, effluent treatment plants,
and solar powered sewage treatment plants.
Reverse
osmosis can be used in a small-scale solar WTP to produce drinking
water for households, communities, or small businesses.
An
ETP can be used in a small-scale solar powered water treatment plant to
treat wastewater from households, communities, or small businesses.
Depending
on the plant’s capacity and the treatment techniques employed, the
price tag of an ETP in a solar-powered water treatment facility might
range widely. The long-term savings and environmental benefits, however,
may make it the more affordable choice.
The
maintenance required for a solar operated water treatment plant is
similar to that of a conventional water treatment plant, including
regular cleaning and servicing of the equipment, monitoring of water
quality, and replacement of filters and membranes as needed.
A
solar operated water treatment plant can be installed in almost any
location, as long as there is adequate sunlight and space for the
equipment.In order to provide a more
stable and long-lasting energy supply, a solar-powered water treatment
facility can be combined with other renewable energy sources like wind
or hydro power.
The lifespan of a
solar operated water treatment plant can vary depending on the quality
of the equipment and the level of maintenance, but it can last for up to
25-30 years with proper care.
