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.
