Water and Sanitation An Innovative New Approach
PROVIDENT WATER ENERGY
Energy efficient waste water facilities
ELECTRO-
COAGULATION
ARSENIC
REMEDIATION
About 140 million people worldwide
are exposed to toxic concentrations of
naturally occurring arsenic in
groundwater supplies, the vast
majority living in rural areas
The slow accumulation of arsenic in
the body causes skin lesions, gangrene,
multiple types of cancer,
cardiovascular diseases, reduced IQ in
children, neuropathy and premature
death.
PROJECT BACKGROUND:
The Issue:
Arsenic contamination in groundwater
About 140 million people worldwide affected
Concentrations can exceed WHO standards by up
to 100 times
Arsenic poisoning can be painful, socially
ostracizing, or fatal
Arsenic is tasteless, colorless, odorless and has no
immediate effects
“Technological graveyard” situation: currently
available technologies are either inefficient,
unaffordable, or not culturally adapted
Our Motivation:
Improve health and livelihood of
millions worldwide
Emphasize a sustainable and
appropriate technological solution
The Need:
Efficiency: Prevent prolonged contact
with arsenic in drinking water
Acceptability: Ensure financial, time
and social burdens are socially
acceptable
The Technology:
Low Cost Electro‐Coagulation
Known wastewater technology, yet never
applied to drinking water
Series of 3 distinct processes:
1. Dosing: Formation of Arsenic‐Binding
Corrosion Products (ABCP) through
electrochemical dissolution of iron
electrodes
2. Mixing: Coagulation of ABCP with
arsenic
3. Filtration: Mechanical removal of the
arsenic‐ laden ABCP
The System:
Community‐Based Center with
Full Cost Recovery
Sustainable with renewable
power
( solar/micro wind mill)
Encourages local participation
Scalable and replicable
Provide energy from solar/micro wind
mill in off‐grid rural communities
efficient, robust, and simple
flow‐reactor
Adapt to local culture
Presenting
Plasma Electro-Oxidation Plasma Electro-oxidation is a unique and latest technology successfully
implemented in various countries. Advantages are:
No addition of chemicals for coagulant
Very low operating cost
Less requirement of space and civil work
Kills Bacteria and coliform
Removal of Heavy metals
Simple, easy to operate and maintain
Advantages of the proposed
treatment scheme:
Low operating cost
Very small Footprint
Low emission of CO2 and Methane.
Can handle any Shock loads, no failures due to shock loads
The process itself is disinfecting the bacteria and
thus reduces the Coliform and E-Coli extensively.
Plasma Electro-Oxidation It is one of most powerful commercially available oxidants &
disinfectant for water treatment. Compared to Chlorine, the most
common water disinfection chemical, it is more than 50% stronger
oxidizer and acts over 3000 times faster. In addition to its capabilities,
it is an environmentally friendly method of treatment without creating
harmful by products or significant residues.
Plasma Electro-Oxidation
Features:
100% Chemical free
No Eye & Skin Irritation
Strongest in disinfection
Removes odors, colors & Toxins
Oxides metal and organic matter
No harmful by products
No negative impact
Huge electricity savings
Simple, easy to operate and maintain
Distinct Advantages:
Low Capital cost
Less foot print and land requirement
Low Carbon Foot print
No Odor Problems
Solar powered plants could be made
Plants can be installed any where
Disinfection in ECO- friendly way, No chlorine is used
Crystal Clear and safe drinking water
Simple, easy to operate and maintain

Drinking water Treatment
Ozone with Filtration
techniques is the best
solution for Arsenic
Removal.
We are developing a
innovative product
without use of Electric
power to provide safe
drinking water free from
Arsenic.
Based on Hand pumping
and Solar power, this will
be a green Pump and
could save thousands of
lives.
