SepaTech

Overview of SepaTech

With water pollution and scarcity becoming critical global issues, securing safe and sustainable water resources is more urgent than ever. Contaminants such as heavy metals, radioactive substances, and organic matter in domestic and industrial wastewater pose serious threats to human health and the environment.

To address these challenges, we developed the SepaTech Contaminated Water Purification System, utilizing cutting-edge microbubble technology.
Microbubbles—tiny bubbles less than tens of micrometers in diameter—enable three key purification mechanisms during their generation, shrinkage, and collapse in water.

  1. Flotation and Separation：Microbubbles attach to pollutants and carry them to the surface for removal.
  2. Oxidative Decomposition：When combined with ozone, they encapsulate oxidants to break down persistent pollutants.
  3. Cavitation Effects：Shockwaves from bubble collapse induce chemical and physical reactions that enhance contaminant removal.

Demonstration experiments have confirmed the system's effectiveness in removing cesium-134/137, heavy metal ions, and tritium—substances that are difficult to treat with traditional physical or chemical methods.
With high efficiency, low cost, and no need for chemical additives, SepaTech offers versatile applications—from emergency response in disasters to industrial wastewater treatment and clean water access in developing regions.

This page provides an in-depth look at SepaTech’s mechanism, development background, verification data, comparison with conventional methods, and future potential.
