DEPure uses dielectrophoresis — electric field gradients — to concentrate and remove microplastic particles from water continuously, without membranes, chemicals, or moving parts.
Current filtration methods cannot remove particles below 10 µm reliably. Membranes clog, chemicals add cost, and centrifugation requires energy-intensive infrastructure. There is no scalable, affordable solution.
DEP is the force exerted on polarisable particles in a non-uniform electric field. We tune frequency and voltage to selectively concentrate microplastics — the field does the work, not filters.
Contaminated flow passes over laser-scribed FTO glass with interdigitated electrode geometry
Alternating current between electrode fingers generates a field gradient — strongest at finger edges
DEP force deflects microplastics sideways into a collection chamber while water flows forward
Clarified water exits the main channel. Particles are flushed periodically to waste — no downtime
DEP concentration of polyethylene microplastics confirmed across multiple frequencies and water types. Visible water clarification observed within minutes under laboratory conditions.
Pharmaceutical and municipal water treatment represent immediate high-value entry points. Consumer filtration follows once industrial performance is demonstrated.
We have demonstrated the effect. Now we build the system. Join DEPure at the start of something that scales globally.
