Raw water unit
The raw water unit consists of a raw water tank and a raw water pump. The raw water is stored in the raw water tank, effectively reducing the impact of pressure fluctuations in the raw water pipeline on direct drinking water equipment.
Preprocessing unit
The pre-treatment unit consists of a multimedia filter, an activated carbon filter, a softening filter, etc. Multi media filters mainly remove large particle impurities, suspended solids, colloids, etc. from raw water; Activated carbon filters remove harmful substances such as free chlorine, microorganisms, organic matter, and some heavy metals from water through the adsorption capacity of the pores on the surface of activated carbon; Softening filters mainly use nano softening resins to remove calcium and magnesium ions from raw water and reduce its hardness.
Membrane processing unit
The membrane treatment unit consists of precision filtration equipment, booster pump, and filtration membrane equipment. The precision filtration equipment is installed with an accuracy of 5 μ The m filter element removes any coarse particles that may affect the membrane equipment in the pre-treatment water, and the membrane equipment removes dissolved organic matter and inorganic pollutants from the pre-treatment water
Post processing unit
The post-processing unit consists of an ozone disinfection system, a clean water tank, and a ultraviolet disinfection device. The strong oxidizing ability of ozone can eliminate bacteria through biochemical reactions. The clean water tank serves as a buffer for direct drinking water, ensuring reasonable water usage during peak periods.
Circulating water supply unit
The circulating water supply unit consists of a variable frequency water supply pump group, a food grade supply and return water pipeline, and a return water fine filtration equipment. Adopting same process design with no dead corners. Ensure stable water quality and ensure safe and hygienic water supply.
Smart integrated direct drinking water equipment relies on its PLC as the control core. The control is mainly divided into the following two control modes:
- Manual mode: When the selector switch is turned to the manual state, each button switch can independently control the start, stop, opening and closing of the process pump, solenoid valve, sterilizer, etc., and is not affected by signals from pressure sensors, liquid level gauges, etc.
- Automatic mode: When the selector switch is turned to the automatic state, the original water tank replenishment solenoid valve automatically replenishes water according to the liquid level in the original water tank. If the liquid level in the raw water tank is too high or too low, the system will alarm. At the same time, the raw water pump automatically turns on according to the liquid level in the clean water tank, and sends the water stored in the raw water tank to the pretreatment unit. During the process, the pressure difference between the inlet and outlet pressure sensors of each filter is used to determine whether each filtering equipment is in a normal state. Exceeding the set value (the value can be modified) will cause the system to alarm. The pre-membrane booster pump starts when the pressure in front of the pump is higher than 1 bar and the pressure after the pump is lower than 13 bar, and the water is sent to the membrane unit for treatment. The water flowing out of the membrane module directly enters the clean water tank for storage. During this period, the pressure difference before and after the membrane is monitored in real time. If it exceeds the set value, the system will alarm and the backwash system will start running until the backwash is completed. The variable frequency water supply pump delivers high-quality direct drinking water to users according to the water outlet pressure set by the user. The circulation pump automatically starts the ozone treatment cycle according to the liquid level in the clean water tank.
Food is the first priority for people, and water is the first priority for food. Water is a substance closely related to life and is increasingly valued by people. In recent years, with the continuous development of industrial production, accidents of surface water contamination have occurred one after another, directly threatening the safety of people’s domestic water and drinking water. On the other hand, with the steady increase in my country’s overall economic strength, Chinese residents’ requirements for urban water supply
The focus on services and water quality has been upgraded from the satisfaction of water quantity. Paying attention to health and water quality has become a social demand for urban water supply.
So how to solve this social need? As a leading enterprise in the domestic water supply industry, Shanghai Kaiquan (Pump Industry) Group Co., Ltd. has the responsibility and obligation to serve as an industry leader. It organized dozens of experts and scholars in the water supply and drainage industry, invested millions of funds, and successfully developed a smart integrated direct drinking water system. equipment to meet users’ needs for water quality. Water treated by direct drinking water equipment can effectively remove heavy metals and hormones in the water, and can be drank directly, which is more convenient and healthier.
Residential housing: residential quarters, apartments, villas, etc.

- Standardized design of the whole machine
Direct drinking water equipment and control systems adopt standardized designs to reduce the debugging time of technicians, reduce various after-sales problems caused by imperfect procedures, and improve the efficiency of solving after-sales problems.
- Beautiful and practical, easy to use
The appearance of the direct drinking water equipment adopts Kaiquan’s new generation industrial design, and the surface adopts the trinity spraying process. The control cabinet adopts German Rittal standard design and adopts fully automatic integrated intelligent control design. It works automatically, will automatically shut down for minor faults and automatically alarm for major faults, saving usage and maintenance costs.
- Dual PLC redundant design
The two systems of main control and backup control are mechanically isolated. Each control system can independently complete all monitoring functions, ensuring that the failure rate of the control system is reduced by 50%.
- Real-time water quality detection
The control system integrates many water quality detection sensors. The PLC can detect various indicators of water quality (residual chlorine, turbidity, TDS, PH, dissolved oxygen, etc.) in real time, and alarm in real time when the normal value is exceeded, ensuring the health and reliability of the effluent water quality.
- Remote data monitoring
The control system integrates the Far EasTone gateway module. You can check various data of the equipment operation, alarms, etc. on the mobile APP and web platform anytime and anywhere without leaving home (the gateway is equipped with edge computing).
- Accumulated running time of each unit
Record the cumulative usage time of each filter unit, and automatically back-clean/remind manual back-cleaning when the set time is exceeded. If the recommended cumulative usage time is exceeded, you will be reminded to replace membranes and other consumables.
- Safe and reliable
Food-grade pollution-free stainless steel pipes, nuclear-grade welding technology, standard Guanlong valves, and international high-end brand membrane modules ensure the safety and reliability of the equipment.
