What is the full name of the water purification technology project presented by Team INNOVATORS?
Project: Hybrid Ultrasonic Bio-Filtration & UV-C Sterilization System.
What is the primary limitation of standard UV water sterilization systems when the water is even slightly cloudy (turbid)?
Sediment particles can "shadow" bacteria and viruses, shielding them from the sterilizing UV-C light.
The phenomenon where sediment in cloudy water shields pathogens from UV light, reducing effectiveness, is known as the _ effect.
shadowing
How does this hybrid system eliminate the 'shadowing' effect that limits conventional UV purification?
By converting the water into a fine mist, ensuring every single droplet is fully exposed to UV-C light with no place for pathogens to hide.
What are the three main processing stages in the system's architecture, following the water inlet?
Stage 1: Bio-Sand Pre-Filtration, Stage 2: Ultrasonic Atomisation, and Stage 3: UV-C Sterilisation.
What is the function of the first stage, the Bio-Sand Pre-Filtration Unit?
It removes sediment, suspended solids, and organic pollutants like impurities and odours.
What three materials form the graded layers in the Bio-Sand Pre-Filtration unit?
Graded gravel, fine sand, and activated charcoal.
What specific role does activated charcoal play in the pre-filtration stage?
It absorbs organic pollutants, impurities, and odours.
Besides purification, what protective function does the pre-filtration stage serve?
It safeguards the delicate electronic components in the subsequent stages from sediment damage.
What is the name of the second stage, where filtered water is turned into a fine mist?
Stage 2: Ultrasonic Atomization.
What is the key component in the Ultrasonic Atomisation Chamber that converts liquid water into mist?
A piezoelectric transducer.
At what frequency does the piezoelectric transducer vibrate to atomize the water?
1.7 MHz.
The process of using high-frequency vibrations to convert liquid into a fine mist is also known as "_ vaporization."
cold
What is the main advantage of converting water into a mist for the sterilization process?
It dramatically increases the water's surface area, preparing it for total sterilization.
What is the name of the third stage, also referred to as the "Kill Chamber"?
Stage 3: Concentrated UV-C Sterilization.
What specific wavelength of UV-C light is used in the sterilization tube?
254nm.
What is the purpose of the polished aluminum reflectors lining the UV-C sterilization chamber?
They ensure maximum, 360-degree exposure of the mist to the UV-C light.
What biological component of viruses and bacteria does the 254nm UV-C light completely destroy?
Their DNA.
What is the final process that returns the sterilized mist to its liquid form for collection?
Condensation.
After sterilization, the mist makes contact with a _ to condense back into pure, liquid water.
cooling plate
What is the function of the 'Attractor Fan' shown in the system architecture schematic?
It pulls the atomized mist through the UV-C sterilisation tube and towards the condensation unit.
What is the goal of the 'Hybrid Advantage' described as 'Nature-Based Reliability'?
The Bio-Sand filter removes sediment and organic pollutants, providing a robust foundation for the system.
Which technology in the system provides the 'Hybrid Advantage' of 'Precision Technology'?
Ultrasonic atomisation, which creates a fine mist to enable total UV exposure.
The system's ability to neutralize 99.9% of all pathogens demonstrates which 'Hybrid Advantage'?
Uncompromising Safety.
What is the name of the first planned enhancement, aimed at preventing transducer damage?
Improvement 1: Fluid Level Management.
What feature is planned to be implemented for Fluid Level Management?
A water level indicator (electronic sensor).
What two potential failures does the water level indicator prevent?
It prevents overflow and protects the piezoelectric transducer from running dry (dry-firing).
What is the name of the second planned enhancement, designed to increase the water output rate?
Improvement 2: Thermal Efficiency.
What specific component is proposed to improve the system's thermal efficiency?
A Peltier cooling chip.
How does integrating a Peltier cooling chip enhance the system's performance?
It creates a more efficient cool condensation surface, thereby increasing the pure water output rate.
Term: Peltier Cooling Chip
A thermoelectric cooling device that accelerates the condensation of sterilized mist back into a liquid state for a higher yield.
According to the system objective, the purifier combines traditional mechanical filtration with ultrasonic atomization to ensure what grade of water safety?
Medical-grade water safety.
The technical enhancements table mentions using modular trays for the bio-sand filter. What is the stated impact of this feature?
It simplifies maintenance and ensures consistent pre-filtration clarity.
