Douglas Hwang has been working on water filtration issues for three decades and he believes the latest product from Waukesha-based startup Corncob Inc. could solve many of the industry’s challenges.
The Corncob II, which uses a membrane technology, can filter many different types of water into potable drinking water in a single step.
