Product description

1、 Fully Automatic Reverse Osmosis Pure Water Machine
The fully automatic reverse osmosis pure water machine is an intelligent device that achieves deep purification through reverse osmosis (RO) membrane technology. Its core feature is fully automated operation without manual intervention, and it is widely used in household, commercial, and small industrial scenarios.
1. Core structure
Pre treatment system: PP cotton filter (removes sediment and rust), activated carbon filter (adsorbs residual chlorine and odors), precision filter (5 μ m, protects RO membrane).
Reverse osmosis (RO) unit: RO membrane (pore size 0.0001 μ m, core desalination component), high-pressure pump (providing 1.0-1.5MPa pressure).
Automatic control system: PLC or microcomputer controller, solenoid valve, liquid level sensor (linked start stop), conductivity monitor (automatic discharge beyond standard).
Auxiliary components: pure water tank (storage), pressure tank (small equipment), rear activated carbon (improves taste).
2. Working principle
After pre-treatment, the raw water is pressurized by a high-pressure pump to push water through the RO membrane. Water molecules pass through the membrane to become pure water, while salts, bacteria, etc. are intercepted and discharged with concentrated water; The system automatically monitors the water tank level through sensors, starting water production when the level is low and stopping when the level is high. At the same time, it automatically completes flushing and fault alarms (such as filter blockage and membrane fouling).
3. Advantages and Applicable Scenarios
Advantages: Fully automatic operation (no manual operation required), stable water quality (conductivity ≤ 50 μ S/cm), suitable for continuous water demand.
Applicable scenarios: home direct drinking, office, small food processing plants, laboratories (scenarios requiring stable pure water supply).
2、 Manual Pure Water Machine with Water Tank
A manual pure water machine with a water tank is a relatively simple pure water equipment that relies on manual operation to control the water production process, making it suitable for cost sensitive or low water frequency scenarios.
1. Core structure
Preprocessing unit: manually controlled sand/carbon filter tank (or replaceable filter element), precision filter.
Reverse osmosis unit: RO membrane module, manual high-pressure pump (requiring manual start stop), concentrated water regulating valve (manual control of recovery rate).
Water storage unit: Large capacity pure water tank (50-500L, mostly made of PE or stainless steel), without automatic liquid level linkage.
Auxiliary components: pressure gauge (manually monitoring pressure), manual flushing valve (regularly manually flushing RO membrane).
2. Working principle
Manually start the raw water pump and high-pressure pump. After pre-treatment, the raw water enters the RO membrane for water production, and pure water flows into the water tank for storage; After the water production is completed, the equipment needs to be manually turned off and the flushing valve should be manually opened regularly to clean the membrane surface; Water quality requires manual sampling and testing (such as using a conductivity pen).
3. Advantages and Applicable Scenarios
Advantages: Simple structure, low cost (30% -50% lower than fully automatic equipment), easy maintenance (no need for complex circuits).

3、 Ultraviolet Water Filtration System
The ultraviolet water filtration system is a physical disinfection device that uses ultraviolet (UV) radiation to kill bacteria. Its core function is to inactivate microorganisms, and it is often used in conjunction with other water purification equipment as a final treatment.
1. Core structure
UV tube: wavelength 254nm (highest sterilization efficiency), power selected according to processing capacity (10-1000W).
Reactor: Stainless steel chamber (water flow channel) to ensure uniform water flow and avoid dead corners.
Control components: timer, lamp running indicator light, fault alarm (such as lamp damage).
Pre treatment (matching): Pre filter is required (to reduce turbidity to ≤ 1NTU and avoid affecting UV penetration).
2. Working principle
When water flows through the ultraviolet reactor, 254nm ultraviolet radiation destroys the DNA structure of microorganisms (bacteria, viruses, algae), causing them to lose their reproductive ability and achieving a sterilization rate of over 99.9%; No chemical additives, no change in water quality and taste.
3. Advantages and Applicable Scenarios
Advantages: Fast sterilization (instant effect), no secondary pollution, easy integration (can be connected in series with RO system or water tank).
Applicable scenarios: Disinfection of direct drinking water terminals (such as RO water purifiers), disinfection of swimming pool water, sterilization of food processing water, and disinfection of rural well water (used in conjunction with filtration equipment).
4、 Comparison and combination application of three types of devices
Equipment type, core functions, automation level, applicable to typical water quality combination scenarios
Fully automatic reverse osmosis pure water machine for deep desalination and impurity removal, fully automatic high salt and highly polluted water for home drinking+ultraviolet disinfection (to enhance microbial safety)
Manual pure water machine with water tank, basic desalination, manual operation of water storage, moderate pollution water source, rural water supply+sand filtration pretreatment (reducing maintenance difficulty)
UV water filtration system for sterilization and disinfection, semi-automatic low turbidity clear water RO water production terminal+UV (ensuring sterile direct drinking)
summarize
The fully automatic reverse osmosis pure water machine is suitable for scenarios that require high water quality and convenience;
A manual pure water machine with a water tank is suitable for scenarios with limited budget and low water usage frequency;
The ultraviolet water filtration system, as a “sterilization kit”, needs to be used in combination with filtration equipment to ensure water quality safety. The three can be flexibly matched according to needs, covering the entire process of water purification from pretreatment, desalination to disinfection.
