Introducti
on
Arsenic, carcinogenic element, a poisonous element presents  
in water to filter it out before use for drinking and in pre-  
treatment of wastewater treatment plants.
As the problem of drinking water contamination alone affects
more than 150 million people worldwide.
Therefore, several conventional techniques have been used to  
remove arsenic (As), including oxidation, coagulation,  
adsorption, etc., but due to their maintenance costs, there is  
a push for sophisticated, affordable nanofiltration membrane-  
based technology
With the aid of

 Chemical precipitation,
adsorption,
coagulation, filtering etc. are  
some of the developed  
techniques for removing "As."
 In the area of separation  
technology, nano adsorbent  
filtration is a technology that is 
 advancing.
 Nano adsorbent technology for 
 the filtration of drinking water 
 has recently gained popularity 
 due to its ease of use,  
adaptability, stricter  
restrictions, lower costs, and  
expanding commercial  
availability of a wide range of  
membranes

It simply needs a small quantity of energy and no chemicals or
additions.
Additionally, the world population is growing at a rate of 80 million  
per year, which causes a 64 billion cubic metre annual increase in  
water consumption
In recent years, one of the biggest health risks has emerged 
because
of drinking water that contains arsenic
[email protected]
The USEPA, WHO and EU reduced the initial arsenic contamination 
level  of 50 ppb to a maximum of 10 ppb.
Therefore, reducing these health hazards for those who live close to 
water  bodies with high arsenic levels requires a focus on arsenic 
remediation

Adsorption is thought to be the least expensive
Most adsorbents, according to the literature, cannot be employed in field
applications
because of problems with their poor adsorption capacity and excessive
levels of particle leaching into filtered water, which pose health risks

Ultra-low-cost 
catalytic, nano  
adsorbent filter for 
arsenic  removal
[email protected]
Arsenic, carcinogenic element, a poisonous element presents in  
water to filter it out before use for drinking and in pre-treatment of  
wastewater treatment plants
WATERMAN ENGINEERS AUSTRALIA has developed a completely
indigenous ultra-low-cost filter capable of absorbing arsenic
This easy-to-handle filter is made from catalytic nano adsorbent  
along with sand or carbon filtration system or dual media filtration  
unit that has the capacity to adsorb arsenic
Arsenic nano adsorbent 
 filters benefits
Compared to other search available  
filters in market, this nano adsorbent  
filter media is appropriate for the socio- 
 economic conditions of many 
countries.
• This filter has a very long lifespan of around five years.
• Throughout its lifetime, the absorbent doesn't need to
be renewed.
• The household filter is not powered by electricity.
• The household filter has a daily capacity of 80 to 100 
 litres.
• The price of the treated water per litre is less than 
that

of other available filters

market is seven times less

This adsorbent has extraordinarily  
high levels of metal oxide  
nanoparticles that are capable of  
adsorbing arsenic integrated inside 
 a robust composite polymer 
matrix

The large surface area of this material and the reaction kinetics strength that  
distinguish it from all other arsenic removal techniques allow for the practically  
total removal of arsenic from running water

This treatment nano adsorbent filter media system has 
 been able to consistently reduce arsenic levels to non- 
 detectable levels in the drinking water as well as pre-  
treated water for wastewater treatment
The nano adsorbent filter media needs to be  
backwashed periodically to remove particles trapped 
 in the media 1
