Primary Reverse Osmosis + Fully Automatic Belt Water Tank + Precision Filtration Water Treatment Equipment

This is a cost-effective, high-stability water purification system designed for medium and small-scale industrial or commercial pure water demand scenarios. It integrates primary reverse osmosis (RO) core purification, fully automatic belt-type water tank storage, and precision filtration polishing treatment. The system features simple operation, stable water quality output, and low maintenance costs, suitable for non-hazardous environments with general pure water requirements.

Core System Components & Functions

Component	Core Function	Key Design Features
Pretreatment Unit (Quartz Sand + Activated Carbon Filter)	Preprocess raw water to meet RO inlet requirements; protect RO membrane from clogging and oxidation.	- Quartz sand filter: Removes suspended solids, sediment, rust ≥20μm; reduces turbidity to ≤1 NTU. - Activated carbon filter: Adsorbs residual chlorine (≤0.1mg/L), organic matter, odor; TOC removal rate ≥60%. - Automatic control: Backwashing triggered by pressure difference (ΔP≥0.2MPa) or time (24h interval); no manual operation required.
Primary Reverse Osmosis (RO) Unit	Core purification module; removes 95–99% of dissolved salts, heavy metals, bacteria, and colloids.	- Membrane type: Low-pressure polyamide composite membrane (cost-effective, suitable for tap water/groundwater treatment). - Operating parameters: Working pressure 1.0–1.5MPa; recovery rate 55–70%; product water conductivity ≤1.3μS/cm (25℃). - Automatic protection: Overpressure shutdown, low-flow alarm, high-conductivity drain; PLC intelligent control of pressure, flow rate, and water quality.
Precision Filter	Final polishing treatment; removes fine particles ≥1μm from RO product water; prevents secondary contamination.	- Filter element: PP melt-blown pleated filter (high filtration precision, easy replacement). - Design advantage: Compact structure, low pressure loss; pressure difference monitoring (replace element when ΔP≥0.15MPa). - Application value: Improves water clarity; protects subsequent water-using equipment (e.g., water dispensers, industrial nozzles).
Fully Automatic Belt Water Tank	Stores purified water; stabilizes water supply pressure; matches RO production capacity with water consumption demand.	- Structure type: Belt-type floating ball water tank (automatically controls water intake and stop; maintains stable liquid level). - Material: Food-grade HDPE/304 stainless steel (non-toxic, corrosion-resistant; complies with GB 4806 standards). - Automatic functions: Liquid level sensor triggers RO start/stop; overflow protection; drain valve for regular cleaning.
Supporting Auxiliary Equipment	Ensures continuous and stable operation of the entire system.	- Booster pump: Provides stable pressure for pretreatment; protects RO from insufficient inlet pressure. - Cartridge filter (5μm): Installed before RO; removes fine particles to prevent membrane puncture. - Control cabinet: Integrates PLC, touch screen, and electrical components; realizes one-key start-stop and fault alarm.

System Workflow

Pretreatment Stage

Raw water (tap water/groundwater) is pressurized by the booster pump and enters the quartz sand filter to remove large suspended particles, then flows into the activated carbon filter to eliminate residual chlorine and organic matter. The effluent meets RO inlet standards: SDI < 5, residual chlorine < 0.1mg/L, turbidity ≤ 1 NTU.
Primary RO Purification Stage

Pretreated water passes through the 5μm cartridge filter and is pressurized to the working pressure by the high-pressure pump, then enters the RO membrane module. Water molecules permeate the membrane to become pure water, while concentrated water (containing impurities) is discharged. The PLC system monitors conductivity in real time; if the value exceeds the standard, the water is automatically drained until the quality is qualified.
Precision Filtration & Storage Stage

Qualified RO product water enters the precision filter to remove fine particles ≥1μm, further improving water quality. The purified water is then stored in the fully automatic belt water tank. The floating ball valve in the tank automatically controls the RO unit to start when the liquid level is low and stop when the level is high, ensuring a continuous and stable water supply.

Key Advantages & Application Scenarios

1. Core Advantages

Cost-Effective: Primary RO configuration balances purification efficiency and investment cost; suitable for users with general pure water requirements (conductivity ≤1.3μS/cm).
Fully Automatic Operation: One-key start-stop, auto backwashing, auto liquid level control; no professional operator required, reducing labor costs.
Stable Water Supply: Belt water tank buffers the difference between RO production and water consumption; avoids pressure fluctuations in the water supply pipeline.
Easy Maintenance: Standardized components, simple structure; filter element and membrane replacement are easy to operate, with low maintenance difficulty.

2. Typical Application Scenarios

Commercial Field: Pure water supply for drinking water stations, office buildings, hotels, and schools; meets daily drinking and catering water needs.
Light Industry: Water treatment for food and beverage processing, cosmetics production, and printing and dyeing; provides qualified process water.
Industrial Auxiliary Water: Cooling water for machine tools, cleaning water for electronic components, and boiler feed water (low-pressure boilers).
Medical & Laboratory: Pure water preparation for small clinics, research laboratories, and instrument cleaning (non-injection grade).

Operation & Maintenance Notes

Pretreatment Maintenance
- Backwash the quartz sand and activated carbon filters once every 24 hours (10–15 minutes each time); manually backwash immediately if the pressure difference rises sharply.
- Replace activated carbon every 6–12 months; replace quartz sand every 2–3 years (or according to water quality test results).
RO System Maintenance
- Replace the 5μm cartridge filter element every 1–2 months to prevent membrane contamination.
- Clean the RO membrane with acid-alkali cleaning agent every 3–6 months; replace the membrane every 2–3 years (if the desalination rate drops below 90%).
- Regularly check the high-pressure pump; lubricate the bearing every 6 months to ensure stable operation.
Precision Filter & Water Tank Maintenance
- Replace the precision filter element every 1–3 months (based on pressure difference and water consumption).
- Clean the belt water tank every 1–2 months; drain the tank, scrub the inner wall, and disinfect with chlorine dioxide to prevent microbial growth.
- Check the floating ball valve regularly; ensure it can accurately control the liquid level and avoid water overflow or dry burning of the pump.
