© United Waters International AG 2015

UWI is at the forefront of sustainable, environmentally friendly and natural water purification technologies with proven results and high demand

Result of 30 years of R&D initiated and led by Swedish inventors and a team of scientists from

Royal Institute of Technology, Stockholm

developed and patented the most advanced biological, cost-efficient raw water purification

technology.

50 water plants have been installed under long-term PPP model

UWI was among 28 technologies evaluated by the Ministry of Water in China and selected as the

preferred solution for smaller cities; signed agreement to roll-out 5,000 water plants

Effects

Bad taste & color, liver and kidney problems and high corrosion

in pipeline that causes more contaminants

Diarrhea, stomach pains, headaches

Skeletal fluorosis, increased risk of Alzheimer's disease,

depressed activity of the thyroid gland, can be fatal

Skin, lung, bladder and kidney cancers also damages the

nervous system, can be fatal

Dermatological cancer, hematological morbidity, inborn

deformities & immune system deficiencies

Increased risks of cancer

The use of birth control pills found in surface waters is

feminizing males (including humans, animal and fish )

IndiaArsenic & Fluoride contamination affected areas

>435 blocks with Arsenic contamination

70 million at risk of Arsenic poisoning

from groundwater

>2000 blocks with Fluoride contamination

>90 million at risk of Fluoride poisoning

from groundwater

More than 150 Million People affected – outcome maybe lethal!

7


Goal of The Government

NO short-cuts possible for a sustainable solution

Must evaluate technology on lifecycle basis!

Deliver clean and healthy drinking water to consumers- eliminate contamination e.g. Arsenic and fluoride

aquifer remediation – to ensure clean water for agriculture as well

Find technologies that are sustainable and cost effective on lifecycle.

Ensure aquifer sustainability.

Should probably should be

The Drinking Water Challenge

Concerns with Conventional Water Purification

Use of harmful chemicals

Water loss of 15-30%

Frequent replacements (Filters

& membranes)

Very High Lifecycle Costs

High energy consumption

(High CO2 Footprint) High pressure

Sludge

(High water footprint)

Costly and bad for environment

High O&M cost

Low Quality Purification Does not comply to Water standard

After Purification

Rudolph Martinell (1941 – 1998)

Thinker and Inventor Ahead of His Time

Developed unique biological water

purification and energy saving systems

together with Royal Institute of

Technology in Stockholm

The ability to purify water without the

use of chemicals or production of

sludge through the proprietary

technology of BioEcoTech®

His ideas were never exploited on an

industrial scale!

15


The Right SolutionThe formation of highly structured Ironhydroxides

The Bacterial Iron oxidation

process creates the Hamotite or

Geotite precipitations

The precipitations have the form

of nails on the surface of the

grains

The precipitations are acting as

Ionexchange surfaces

The Adsorption of Arsenic to

these Iron precipitates is well

known

The process is the chemical

equivalent process which is

reverted due to the presence of

oxygen

Iontrex™ Reactions

The Oxygenation unit works with

a unique combination of different

flow and turbidity changers to get

an excellent mixing of air and

water.

The process draws the needed

air in automatically and with the

unique technology we enable a

one-step passage with a

saturation of dissolved oxygen at

very low pressures, saving huge

amount of energy.

The iron oxide forms get adsorbedto filter material, then to this othermetal oxides get further adsorbedand forming multiple layers andsuch layers get built on this material.
