October 10, 2019: Water treatment technology company PowerTech Water has received $1.5 million funding that it will use to commercialize its lead battery water treatment technology, the company said on October 3.
The funding has come from venture capital firms Mazarine Ventures, Commonwealth Seed Capital and Harbor Street Ventures, lead investor Bluegrass Angels and other individual investors.
PowerTech Water has developed what it calls CapCo (Capacitive Coagulation) Modules — 1ft-tall (30cm) devices that it says can extract heavy metals, including lead, from 10 gallons (37 litres) of water a minute.
Its technology consists of carbon electrodes that attract the metals to them and filter them from the water, which can then be neutralized and poured down the drain. This means major savings for battery manufacturers, some of whom PowerTech’s co-founder and CEO Cameron Lippert told BESB the company has already supplied with its modules.
“This is the kind of technology that would really help the smaller guys — and we already have half a dozen in the field,” he said.
“A smaller size plant would produce 50,000 gallons of water per day, six days a week. And for smaller firms, they are small enough to have these problems, but not big enough to have the financial means to address the problems in the most efficient way.”
Lippert says the technology does not use chemicals, there is no toxic sludge generated and operating expenses are reduced by 90%.
“We are currently building modular systems that can treat anywhere from 40-50 gallons per minute, up to 1,000+ gallons per minute,” he said. “And, regardless of the flow rate, the lead that is extracted from the water can be returned to the battery manufacturers for re-use in making new batteries.”
CapCo systems are also being installed by aerospace manufacturers and firms in the automotive industry who need to address their heavy metal effluent problems, Lippert said.
