Series B · Orono, Maine · founded 2011 · 12 employees$6.1Mraised▾
Provider of nanotech-based water treatment solutions for industries. It is developing a patented ceramic filter to remove dissolved solids for softening and concentrating applications, and recovery of valuable by-products. Their proprietary coating process uses commercially available ceramic supports then applies a thin coating of ceramic and DNA. A two-stage heat process hardens the ceramic layer then removes the DNA. The result is a ceramic nano structured material with transverse channels all the way through the material. It shows very tight distribution of pore size and high flux rates. This patented process can produce highly purified water under extreme conditions and at low pressure. This process is mainly used in oil & gas for water treatment in fracking and tar sands.
