ARSENIC REMOVAL SYSTEM

1. Introduction 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. https://watermanaustralia.com/product/arsenic-removal-system/ 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 catalytic, nano adsorbent filter media for drinking water and for the pre- treatment of industrial wastewater, WATERMAN ENGINEERS AUSTRALIA designs, manufactures, and commissions arsenic removal systems to fulfil the growing need for fresh and drinking water. In order to pre-treat for wastewater treatment, it is required to remove Iron and Manganese, which this catalytic, nano adsorbents filtration media will help to do. In order to protect water security, this article focuses on an improved nanofiltration (NF) approach for removing arsenic (As). 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.

2. 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. https://watermanaustralia.com/product/arsenic-removal-system/ In recent years, one of the biggest health risks has emerged because of drinking water that contains arsenic. Public health officials are extremely concerned about high levels of arsenic (As) in drinking water because it can initially lead to skin conditions before later developing into cancer. Arsenic contamination of drinking water is a growing problem worldwide. Multiple cancers may develop in those who consume arsenic-rich water on a regular basis. Considering this, 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 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

3. 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. https://watermanaustralia.com/product/arsenic-removal-system/ This indigenous filter for arsenic removal is low cost and easy to handle. With this technology the people of world can avail arsenic free water. The best filter currently on the market is seven times less effective than the revolutionary filter that nanotechnology engineers at WATERMAN ENGINEERS AUSTRALIA have created, called catalytic nano adsorbent composite filter. This adsorbent has extraordinarily high levels of metal oxide nanoparticles that are capable of adsorbing arsenic integrated inside a robust composite polymer matrix.

4. https://watermanaustralia.com/product/arsenic-removal-system/ 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 catalytic nano adsorbent filter has a surface area like that of carbon nanotube materials. Because nano adsorbent is so effective, one gramme of it has 40% more surface area than the typical available filters in market. 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 media has not required replacements.

5. The nano adsorbent filter media needs to be backwashed periodically to remove particles trapped in the media. The backwash water is discharged to holding tank to allow settling of solids. After sufficient settling has occurred. The supernatant is recycled back through the https://watermanaustralia.com/product/arsenic-removal-system/ entire treatment process. This method of residuals handling is cost effective and has worked well with this media.
