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
  water
• 4 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 carts 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 wheels circumference 59.2 meter per
  minutes. So, 3.55 KM in one hour.

8
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

9
Gear Module

• Generator rotates in one direction, so gear
  module rotates in one direction.
• The gear ratio needed The generators RPM/ The
  wheels
• RPM 50/40 1.25.
• Rotation are transferred by chain

10
The circuit
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.

11
Filtering Process

• Our Objective
• Get same results as boiling
• Micro-organisms
• Chemicals
• Particles
• Filtering techniques we used
• Mesh Filtering
• UV Filtering
• Sun Filtering

12
Filtering Process

• Mesh Filtering
• 20 micron Sediment Filter
• Reduces amount of sand,
• silt, dirt, and other particles.
• Two Layers

13
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

14
Filtering Process

• Sun Filtering
• UV-A Long wave- 315-400 nm
• (PET) Polyethylene terephthalate
• Deactivates diarrhea-causing
• organisms in polluted drinking water2
• Cumulative solar energy
• Aluminum 75 UV Reflectivity1

18
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
