Researchers take a step forward in turning chicken feathers into water filters

Improved technology boosts potential for a low-cost, sustainable solution to the global problem of contaminated water.


 

New University of Alberta research is fluttering closer to turning chicken feathers into an effective filter for water decontamination.


Experiments using two chemical agents have improved how keratin from the feathers adsorbs — or sticks to — heavy metals usually found in surface, well or dugout water used by poultry producers for their stock.


The research shows that for the first time, the bio-based filter can remove up to 99 per cent of eight heavy metals simultaneously — the highest numbers yet, says Muhammad Zubair, who conducted the work to earn a PhD in bioresource technology from the Faculty of Agricultural, Life & Environmental Sciences. 


That finding increases the throwaway poultry byproduct¡¯s potential as a low-cost, sustainable way to solve a larger global problem, he says. 


¡°Access to clean drinking water is a key to building a healthy and sustainable society, yet many countries, like in South Asia, have groundwater that is contaminated with heavy metals. Arsenic alone has affected 137 million people in 70 countries.¡± 


Zubair¡¯s work, supervised by professors Aman Ullah and Roopesh Syamaladevi Mohandas, contributes to ongoing research into bio-based sorbents, led by Ullah through the U of A¡¯s Future Energy Systems program.


¡°An exciting step forward¡±


To help improve adsorption of the protein found in the feathers, Zubair used graphene oxide and nanochitosan in separate experiments, to modify the properties of the keratin. Treating the feathers with the chemical agents created more surface area in the adsorbent — which looks like a black powder — to capture contaminants. 


Both chemical agents proved effective at removing arsenic, cadmium, chromium, cobalt, lead, nickel, selenium and zinc from small samples of simulated wastewater, Zubair¡¯s research showed. 


All of the toxins are also commonly found in wastewater used in processing industries such as oil, gas and mining. 


Boosting the capacity of the adsorbent ¡°is an exciting step forward for greater efficiency,¡± he adds. 


Working with the two chemicals also built a better understanding of the interaction between keratin and heavy metals during adsorption, he adds.


¡°That may help us to further modify the keratin¡¯s properties, to adsorb other heavy metals beyond the eight types we worked with.¡±


Potential for global impact


Though only tested in simulated synthetic water for poultry use, the adsorbent technology has potential tobe used in wastewater from oil and gas processing and other chemical-related industries as well, he suggests.


¡°This technology could go beyond Alberta and have a global impact.¡± 


The chemically treated keratin will now be tested in larger volumes of wastewater, part of the process aimed at eventually bringing it to industrial scale.


Zubair, who also holds a master of science in bioresource technology, was supported in his research by an Alberta Innovates Graduate Student Scholarship, the John and Patricia Schlosser Environment Scholarship and the J Macgregor Smith Graduate Scholarship. The research was also funded by Alberta Agriculture and Forestry (AFC), Results Driven Agriculture Research (RDAR) and the Canadian Agricultural Partnership (CAP).
