Introduction
The solar water purification equipment system is an environmentally
friendly device that uses solar energy as the power source and
combines water treatment technology to achieve water purification.
The core principle is to convert light energy into electrical
energy through solar panels to provide power for water treatment
processes (such as filtration, distillation, reverse osmosis,
etc.), and at the same time, some systems can utilize the thermal
energy of solar energy to assist in water purification (such as
solar distillation). This system is usually composed of the
following parts:
Solar power supply system
1.Solar panels: They are responsible for absorbing solar energy and
converting it into electrical energy, which is stored in batteries
to supply power to equipment such as water pumps and motors.
Controller and inverter: Regulate the output of electrical energy
to ensure the stable operation of the system and support the use of
AC equipment.
2. Water treatment system
According to the water quality requirements, multiple purification
technologies can be integrated:
Pretreatment module: Large particle impurities and suspended solids
are removed through filters, sedimentation tanks, etc.
Core purification module:
Membrane treatment technologies: such as reverse osmosis (RO)
membranes and ultrafiltration (UF) membranes, for the removal of
bacteria, viruses, heavy metals, organic substances, etc.
Distillation technology: It uses solar energy to heat water to
evaporate and condense, and is suitable for high salinity or
wastewater purification.
Ultraviolet (UV) sterilization: Microorganisms are killed by UV
lamps powered by solar energy to ensure water quality safety.
Post-processing module: Add minerals or adjust pH value to improve
taste.
3. Water storage and control system
Water storage tank: Stores purified water and is equipped with a
water level monitoring device.
Intelligent control system: Automatically monitors water quality,
water quantity and equipment operation status, and supports remote
monitoring and fault alarm.
The characteristics of the solar water purification equipment
system
1. Environmentally friendly and energy-saving, with strong
sustainability
Zero carbon emissions: Fully dependent on solar energy, no need for
external grid connection, reducing fossil energy consumption,
suitable for remote areas or off-grid scenarios.
Low operating cost: Solar energy is a free energy source. Long-term
use can significantly reduce electricity expenses and has low
maintenance costs.
Second, it has strong adaptability and a wide range of application
scenarios
Environmental adaptability: It can operate stably in areas without
power supply and with poor water quality (such as disaster-stricken
areas, rural areas, and islands), and is resistant to high and low
temperatures and sandstorms.
Water quality adaptability: It can treat various water sources such
as river water, lake water, groundwater and seawater, and the
effluent meets the standards for domestic drinking water (such as
GB5749).
Iii. Intelligence and Automation
Unattended operation: It automatically starts and stops through
sensors and control systems, and monitors water quality data in
real time, reducing manual intervention.
Remote management: Supports Internet of Things (IoT) access. Users
can view the device status and water quality reports through the
mobile APP, which is convenient for maintenance and management.
Four. Efficient purification, water quality safety
Multiple purification guarantees: By integrating physical
filtration, membrane separation, sterilization and other
technologies, it can remove 99.9% of bacteria, viruses and harmful
substances, ensuring the safety of drinking water.
Stable water production: The system design has a high degree of
redundancy. Even when there is insufficient light, it can maintain
short-term operation through the battery.
Five. Easy to install and simple to maintain
Modular design: Pre-integrated components support quick
installation, no need for complex infrastructure, suitable for
emergency water supply or temporary projects.
Low maintenance requirements: Core components (such as membrane
elements) have a long service life, with a replacement cycle of up
to 2-3 years, and the operation is simple.
Six. Significant social benefits
Solving the shortage of drinking water: Provide clean water sources
for remote areas and disaster-stricken areas, improve public health
conditions, and reduce the spread of water-borne diseases.
Supporting green development: In line with the global low-carbon
trend, it can be used as an environmental protection demonstration
project to promote the realization of the Sustainable Development
Goal (SDG6).
Typical application scenarios
Remote rural areas/mountainous regions: Replace traditional well
water or contaminated water sources to ensure daily drinking water.
Fieldwork/emergency rescue: Provide temporary water purification
solutions for exploration teams, campers or disaster-stricken
areas.
Islands/Ships: Desalinate seawater to meet the water demand in
off-grid scenarios.
Environmental protection project: In conjunction with solar
microgrids, an independent green water supply system is
constructed.
| Technology | Membrane pore size | Mainly remove the object | Typical application scenarios | Energy consumption/Cost |
| Ultrafiltration (UF) | 0.01-0.1μm | Bacteria, colloids, macromolecules | Pretreatment and reclaimed water reuse | Low energy consumption |
| Reverse Osmosis (RO) | 0.0001μm | Inorganic salts, heavy metals, viruses | Drinking water and seawater desalination | High energy consumption (requires pressurization) |
