Dual‑Frequency Ultrasound Platform for Rapid Remediation of Contaminated Solids (Coupled High and Low‑Frequency Ultrasonic Systems and Methods for Remediation of Contaminated Solids, Tech ID: 20-010)
Technology Overview: This NJIT technology couples low‑frequency (LF) bulk agitation with high‑frequency (HF) cavitation to accelerate desorption and degradation of contaminants from soils, sludge, and solid matrices. LF loosens and transports contaminants; HF generates localized cavitation to fragment, oxidize, or detach persistent pollutants, shortening treatment time and reducing chemical use.
Industry Pain Point: Conventional remediation of solids is slow, chemical‑intensive, and often incomplete.
NJIT Solution: Synergistic LF+HF ultrasonics deliver faster, more complete remediation with reduced reagents.
