Double Aeration Built-in Tank Sterilizer

Product Advantages

● 10g Ozone for Powerful Coverage: The 10g/h ozone output can be flexibly allocated to two aeration devices (5g/h per device or adjustable as needed). After dissolving in water, ozone achieves a kill rate of ≥99.99% against Legionella, E. coli, and blue-green algae. Simultaneously, it oxidizes and decomposes biofilm within 1mm of the tank wall and humus in the water, preventing microbial adhesion and growth. This extends the tank cleaning cycle from once per quarter to 1.5 years, significantly reducing labor costs.

● Flexible Dual-Tank Control: The electrical control box has a built-in dual-channel independent control module, supporting two modes: "Dual-Tank Independent Disinfection" (e.g., setting separate operating times for domestic water tanks and fire water tanks) and "Single-Tank Dual-Zone Enhancement" (simultaneous aeration of upper and lower layers in a large-capacity tank, eliminating disinfection dead zones caused by corner sediment). No additional electrical control equipment is required, saving 35% on equipment investment compared to two independent devices, and simplifying wiring management.

● Built-in Aeration for High-Efficiency Oxygen Dissolution: Both aeration devices utilize 304 stainless steel aeration tanks, internally installed 10-30cm below the water level in the tank. Each tank provides an ozone diffusion area of ​​0.3㎡, achieving a water dissolution efficiency of ≥92%, ensuring a stable ozone concentration of 0.3-0.6mg/L in the water. This represents a 28% increase in efficiency compared to external jet aeration, avoiding ozone loss during transport.

● Multi-Environment Adaptability: The aeration devices can be continuously immersed in water with a pH of 4-10 and withstand temperature fluctuations from -10 to 60℃, making them suitable for various water qualities including drinking water, industrial circulating water, and fire-fighting water storage. The electrical control box has an IP65 protection rating, supporting both indoor and outdoor installation. It features a built-in moisture-proof cooling fan, ensuring stable operation even in humid environments with up to 90% humidity, adapting to complex climates such as the rainy season in the south and cold regions in the north.

● Intelligent and Low-Energy Operation: The control box supports "timed cycling" (1-4 time periods can be freely set daily, with a minimum operating unit of 15 minutes), "water level linkage" (optional water level sensor automatically reduces ozone production when the water level is low), and "self-healing" (automatic backflushing for 30 seconds when aeration is blocked, alarm if ineffective). Daily power consumption is ≤0.8 kWh, saving 25% more energy than traditional ozone equipment, enabling unattended management.

Main Functions

● Dual-Path Ozone Distribution Disinfection: The ozone generated by the 10g/h ozone generator is distributed to two aeration devices. The ozone supply and operating time can be controlled via the control box. For example, a domestic water tank can operate twice daily (45 minutes each time), and a fire water tank can operate once a month (2 hours each time), meeting the disinfection needs of different water tanks.

● Multi-Mode Intelligent Control: The control box is equipped with a timer switch, supporting two operating modes: ① Timed mode (operates at fixed times daily); ② Manual mode (one-button activation for emergency disinfection), adapting to different user needs.

Application Scenarios

● Residential Communities with Multiple Water Tanks: One unit controls two 60m³ domestic water tanks. Aeration devices are installed at the bottom of each tank. The electrical control box is installed in the property management's power distribution room. It is set to operate daily between 3-4 AM, solving the problem of microbial growth caused by long-term water storage in secondary water supply tanks, ensuring the water safety of thousands of households.

● Commercial Complexes with Large Water Tanks: For a single 200m³ combined fire-fighting and domestic water tank, two aeration devices are installed, one on the upper level (domestic water area) and the other on the lower level (fire-fighting water storage area). The upper level operates once daily, and the lower level operates once monthly, achieving "one tank, two uses, disinfection on demand," preventing water quality deterioration caused by long-term stagnation of fire-fighting water.

● The factory features multiple water tank systems: It controls one 200m³ cooling water circulating tank and one 100m³ process water tank. The cooling water tank is set to run twice daily (30 minutes each time) to remove algae and prevent clogging. The process water tank runs for 15 minutes every 2 hours to ensure water quality, adapting to the disinfection needs of different water usage scenarios within the factory.

● The hotel has zoned water tank systems: It manages one 150m³ guest room water tank and one 50m³ catering drinking water tank. The catering water tank is set with an ozone concentration of 0.6mg/L (higher standard), while the guest room water tank is set at 0.3mg/L. This differentiated control meets the hygiene requirements of different water usage scenarios.

Application Scope

● Total Compatible Volume: 60-200m³ (coverage of 2 aeration devices combined)

● Single Device Coverage: 30-100m³/unit (ozone distribution ratio adjustable as needed)

● Ozone Parameters: 10g/h total output (air source, purity ≥93%)

● Aeration Device: 304 stainless steel aeration tank

● Water Requirements: Water temperature -5-45℃, turbidity ≤8NTU (pre-filter 5μm recommended), pH 4-10

● Power Supply: AC 220V±15% 50/60Hz (supports wide voltage, adaptable to unstable power grids)

Common Uses

● Daily Preventative Disinfection: As a routine maintenance device for water tanks, it automatically operates according to preset time periods to inhibit microbial growth, maintain water quality stability, and prevent the water in the tank from becoming stagnant and deteriorating.

● Seasonal Enhanced Disinfection: During the high temperatures of summer (rapid microbial growth) and the rainy season (high water turbidity), temporarily increase the operating frequency via the electrical control box (e.g., from once to twice daily) to enhance disinfection and prevent water quality fluctuations.

● Emergency Water Quality Restoration: When water contamination occurs due to pipe repairs, an open manhole cover, etc., activate manual mode, adjust the ozone concentration to 0.8 mg/L, and run continuously for 4-6 hours to quickly kill contaminants and restore water quality to standard.

Usage Precautions

● Installation Specifications: Aeration devices must be kept away from the water tank inlet, outlet, and mixing equipment. The distance between two devices should be ≥2m (≥3m for large-capacity water tanks) to ensure uniform ozone diffusion. The installation height should be no less than 30cm from the bottom of the water tank to prevent sediment buildup from clogging the micropores.

● The electrical control box must be installed at least 3 meters away from the water tank to prevent it from being submerged by overflowing water. New water tanks must have their inner walls cleaned before first use. Old water tanks must have thick biofilm (>1mm) removed to prevent excessive ozone consumption and reduced disinfection effectiveness.

● Operational Safety: Do not open the manhole cover of the water tank while the equipment is running. If sampling is required, stop the machine for 30 minutes and ventilate before operation. Operators must wear respirators (to protect against ozone irritation).

● When modifying operating parameters, pause the equipment first to avoid sudden increases or decreases in ozone concentration. In case of emergency shutdown, first disconnect the power to the electrical control box, then close the water tank inlet valve.

● Maintenance Points:

Check the pipes of the two aeration devices monthly for blockages.

In cold winter regions, exposed pipes must be insulated to prevent freezing and cracking. Before long-term shutdown (>1 month), drain the water from the aeration devices to prevent corrosion.
