CHINA DYE TESTS

Our Beijing office was requested to assist a textile company with diagnosing a competitor’s electrocoagulation waste treatment system that was not performing.

A KASELCO bench top reactor was taken to _______, PRC. Our technicians used a non-standard power supply.

The waste stream was contaminated with a blue textile dye. The dye water was subjected to a single electrocoagulation pass in the KASELCO benchtop pilot reactor. The dye immediately separated from the water and formed a blue floc with the iron, leaving the water clear with no color.

It should be noted that the power supply being used was not standard and both the current and the hydraulic flow were not closely controlled and were not optimum. No delayed-performance test was conducted to determine the stability of the floc following removal.

Although the test used the pilot benchtop, no data was recorded as no measurement equipment was available. The site performed a whiteness comparison test with paper and concluded that the water was clear to the naked eye.
