PEDAL POWER WATER BIKE
“A water filter system, which will benefit millions worldwide”
The pedal power water bike is capable of delivering clean microbiologically
safeguarded water at 14 litres per minute.
PEDAL POWER WATER BIKE
PEDAL POWER WATER BIKE
• This unique innovative design
has been invented and
developed for small
communities with no electricity
or …
• as a first response unit in the
aftermath of civil emergencies
– flooding, earthquakes etc.
PEDAL POWER WATER BIKE
CAPACITY
• Capacity of 14 litres of water
per minute (at 20°C)with easy
effort.
• This brilliant device can easily
sustain 3000 people’s needs in
an emergency – providing
clean purified fresh-tasting
water.
PROJECTS FOR AID GROUPS
• Ideal set up in a remote static
village community situation – it
is capable of sustaining the
needs of 1000 to 1500 people
at 5 litres per person per day.
PERFORMANCE OF THE
PEDAL POWER
The PEDAL POWER is designed to deliver clean
microbiologically safeguarded water.
This unique water treatment system utilising the combination of
technologies ensures potable water quality.
The Dow™ Ultra Filtration Membrane will have an expected life
of 5 years providing it is maintained correctly.
The UF Membrane can be back washed utilising the treated
stored water by switching a series of valves to allow it to be
rinsed clear of accumulated particles.
A venturi is incorporated into the design to introduce air into the
passing water to aid the process.
OPERATION
• The PEDAL POWER UF unit is
capable of drawing water through
the perforated metal intake on a
length of flexible hose, from 4
metres deep – a creek, river,
shallow well or lake.
• A gear pump modified by WWW is
connected by a toothed belt to the
heavy flywheel that has the pedal
attached, for the maximum kinetic
energy.
• A 10 year old child can easily pedal
to filter their family’s daily water
requirements
TECHOLOGY
The revolutionary water treatment system is comprised of 2 separate filtration
processes;
The water to be treated from any river, lake, creek or dam, can be drawn with
the suction line from up to 4 vertical metres to the Water Bike.
1. Sediment Reduction. The water then flows through the control valve,
fitted into the top of the blue fibreglass reinforced plastic tank, down through
an American all- natural environmentally safe, granular filter media with a
large surface area and micro porous structure.
The angularity of the particles, the rough surface and porosity provide a high
surface area which is over 100 times greater than silica sand.
It is a highly efficient filter to reduce dirt, silt, organic material and suspended
matter from the passing water down to between 3 and 5 micron approximately eight times finer than what is visible to the naked eye (40
micron)
OUTSIDE-IN FLOW
CONFIGURATION
2. Ultra Filtration Purification.
Ultra Filtration (UF) is able to achieve
up to 99.9% removal of bacteria and
most viruses. With such high filtration
efficiency UF is an excellent barrier for
drinking water applications.
The UF modules are made from a
bundle of high strength long hollow
membrane tubes inside the white
chamber. Outside-in flow configuration
allows extended use at high flux with
low quality feed sources.
Dow™ UF membranes’ outside-in flow
configuration are less susceptible to
plugging which drastically reduces
cleaning frequencies, energy
consumption and operating costs.
The nominal pore diameter of
0.03micron removes bacteria, viruses
and particulates.
Dow™ Ultra Filtration Advantages
and Certification of Performance
• Dow™ UF modules utilise asymmetric hollow fibre membranes with
pore size distribution that enables effective removal of bacteria,
most viruses, colloids and silt. With the membrane’s uniform pore
size and outside-in flow configuration, the Dow™ UF module is
capable of maintaining efficient and stable performance. When the
trans membrane pressure increases over time, the module can be
cleaned through backwash, air-scour and chemical cleans to restore
module performance.
• Dow™ UF modules have been tested and certified by NSF
international under NSF/ANSI Standard 61 ensuring that they are
safe for use in drinking water systems. Dow™ UF is accepted by
independent bodies (CADPH LRV and Title 22 and EPA
Environmental Technology verification) for its filtration performance
in drinking water and water reuse applications.
