Motivation


Need for the product

• What problem is it addressing

• Earth – Two third water

• Human Body – Approx 70% water

• 1.5 billion people without regular access to water4 Million deaths annually

• People walk an Average of 3.7 miles and spend 16 hours a week (2 hours a day)

Product Overview

Market and Competition


Filtering Products

• Many available• None reusable, self sustaining and durable

Other Methods

• Iodine tablets• Battery powered filters• Charcoal filters

Hand crank

• Cannot be used on the go

Energy Generation

Txt


• DC voltage generator to charge a battery. • Ultraviolet bulbs that work at 12 V DC and have the required specification to kill bacteria.

Current range Calculation

RPM of the cart’s speed

- 47 cm diameter wheel and a stop watch, it was found equal to 40 RPM

- 47 RPM = 50 to 80 Watt for one hour

- Maximum current rating = 70 Watt /12 V= 5.8 A

- Nominal operating current = 40 Watt /12 V= 3.3 A

- 40 RPM x wheel’s circumference = 59.2 meter per minutes. So, 3.55 KM in one hour.

The generator

- RPM generator- Current higher than the calculated currents.

- Permanent magnet DC motor from used car or appliance is powerful and cheap

- Wiper Motor from used vista eagle car 1992 model- 80 watt 12 VDC 6.7 A

- The generation of 13 VDC to 14 VDC was easy at low RPM that was calculated using stop watch. It was found Equal to 50 RPM

Gear Module

- Generator rotates in one direction, so gear module rotates in one direction.

- The gear ratio needed = The generator’s RPM/ The wheel’s

- RPM= 50/40= 1.25.

- Rotation are transferred by chain

The circuit

- The battery and the generator are connected in parallel

- Current flows from generator to the battery when the generated voltage is larger than the voltage of the battery.

The Circuit

Filtering Process


Our Objective

• Get same results as boiling• Micro-organisms• Chemicals • Particles

Filtering techniques we used

• Mesh Filtering• UV Filtering• Sun Filtering

Filtering Process


Mesh Filtering

• 20 micron Sediment Filter

• Reduces amount of sand, silt, dirt, and other particles.

• Two Layers

Filtering Process


UV filtering

• UV-C Short wave- 100-280 nm

• UV Lamps

• Alter DNA of viruses, bacteria molds and parasites

• No chemicals added

• Class A and B

Filtering Process


Sun Filtering

• UV-A Long wave- 315-400 nm

• (PET) Polyethylene terephthalate

• Deactivates diarrhea-causing organisms in polluted drinking water[2]

• Cumulative solar energy

• Aluminum – 75% UV Reflectivity[1]

Combined System


Working together

• Simultaneous charging and lighting• Water movement

Other components

• UV Lamps case• Battery/Generator Cabinet• Water Tap• Reversible movement• UV lamp switch and generator switch• Mesh filter container

Lifetime


UV Lamps - 8000 burning hours[7] (2hrs/day = 730hrs) - Recommended replacement - Annual - Contact retailers

Battery

Generator

Mesh Filter- 6 months life[8]

- Four replacement papers provided

Other parts- Contact retailers

Testing


Testing Steps


Pour the water getting from SFU pond on the mesh filter and exposure it under UV for 10 minutes

Prepare 2 water samples (one is from SFU pond , one is after treated)

Culture Bacteria: Mix the agar and pour it into the dish to cover the bottom Pour 1 ml sample water on the agar Set the dish in a warm dark cupboard for two to three days

Observe the bacteria colonies through the top of the dish

Testing Result (Untreated)


Testing Result (Dilute Untreated Water)


Sample No. Colonies1 372 453 404 265 50

Average 40

Total Colonies:40 * 1000 = 40,000

per 1ML

Testing Result (Treated)


After treatment from aquaQuick, there are only 5 colonies!

99.9875% bacteria have been killed

Testing Result (Compare)


SteriPEN Kills over 99.9% of bacteria and

viruses, and it gets WQA approved.
