Technology Overview

Utilising Baldwin’s custom RM-10 bentonite clay based powder chemical blend, the BCU system enables treatment through a single, highly efficient, automated process.

Conventional wastewater systems typically require multiple chemicals and reaction vessels; the BCU uses one chemical application and one reaction vessel.

Bentonite Clay

The RM-10 bentonite clay based chemical is a dry powder composed of carefully selected and precisely blended minerals, acids, bases, and polymers. These components are formulated so that each becomes active at precisely the required stage of the treatment process. The complete reaction takes place within seconds and combines flocculation, precipitation, and pH adjustment into a unified process.

Process Steps

The treatment mechanism proceeds through the following sequential process steps:

  1. Emulsion Breaking
  2. Oil and Phosphate Attraction
  3. Metal Precipitation
  4. Ion Exchange and Adsorption
  5. Encapsulation and Clarification

The BCU system is available as a standalone system, or with customised pre-treatment and post-treatment options for a complete treatment process. Pre-treatment typically includes removal and collection of free oil from the wastewater, as well as pH adjustment where required, while post-treatment typically includes filtration and disinfection.

Applications
