Advanced E-Team Grant Profile

Arsenic 3
University of California, Berkeley, 2004
$20,000.00

This E-Team has developed a prototype device for removing arsenic from Bangladesh's drinking water. The team plans to conduct a business analysis to assess competing technologies, production costs, and market potential.

The basis for the prototype device is chemically-treated bottom ash (residue left over from coal combustion) as the medium for removing arsenic. The invention is based on coating the surfaces of bottom ash particles with ferric hydroxide, and using this treated ash to react with, remove, and immobilize arsenic in water supplies. Lab results demonstrated that 5 gm of treated bottom ash can reduce arsenic concentration in 2.4 liters of water from 2400 ppb to 10 ppb.

The E-Team believes the final product’s pricing model will be proportional to table salt, costing <.30/kg per person per year. The business costs are also comparable to table salt.

The team consists of four lab-based professionals in chemical engineering and physics. They plan to include students from UC Berkeley to perform lab work and design.
