Water is not only crucial for human health, but also for economic development
This. It is estimated that 15% of global water consumption is industrial water. All important industries rely on
Due to limited water supply, many processes require water - even the final product
An important component of.
As the demand for water continues to rise, it is increasingly becoming a valuable resource.
Expected by 2025
The population will increase by 1.5-2 billion people
2 billion people will migrate to cities
One billion people will not have access to clean drinking water
2.4 billion people will not have access to necessary sanitation facilities
The increasing demand for water and its limitations pose a serious challenge to water consuming users
The challenge.
Challenge
Water users and consumers face the following challenges:
Limited freshwater resources and increasing demand for water
The increasing cost of energy
- Stricter anti pollution laws and water quality standards
ABB has provided hundreds of facilities for the global water treatment industry in the field of water treatment
Having rich experience and extensive professional knowledge, in the current fiercely competitive water treatment industry
Industries can help companies significantly improve their performance. ABB provides efficient and environmentally friendly solutions
Provide water-saving solutions to help them tackle the challenges they currently face, such as:
Advanced electrical system
Supervisory Control and Data Acquisition System (SCADA) for Factory Automation and Water Leakage Management
- Efficient motor
- Variable frequency drives (VSDs) and soft starters used to improve control performance and energy efficiency
Flow and pressure control
The water consumption varies greatly at different times of the day. Therefore, the flow rate and pressure of the pump
Power needs to be controlled. The flow and pressure can be regulated using a frequency converter for power regulation,
Constant speed solutions can also be used, such as imported guide vanes, throttle valves, or hydraulic systems
Coupling for mechanical control.
Pump law
- Flow rate is proportional to rotational speed
Pressure is proportional to the square of rotational speed
- Power is proportional to the cube of rotational speed
Comparison between Constant Speed Control and Variable Speed Control
The most commonly used flow control method is to use a constant speed motor to regulate through a valve. This method
It's like stepping on the accelerator while stepping on the brake to adjust the speed of the car. This method not only wastes
A large amount of energy, and it also wears out equipment.
By using a frequency converter, the flow rate can be changed by simply changing the motor speed, which is like driving a car
Switch to low gear for deceleration while releasing the throttle. The pump can operate under all operating conditions
Work at the Best Efficiency Point (BEP). Frequency converter is the most effective control method - no
But it reduces energy consumption and CO2 emissions, and also significantly lowers the total operating costs.
The benefits of frequency converters
energy conservation
Typical investment return time: less than two years
Improve the efficiency of the system
Extend the service life of equipment
Reduce operating costs
Fast and precise process control
