With the objective of solving the problem of wastewater, a number of innovations have been created under HM the King's royal initiative. For instance, the "Chaipattana Aerator", patented on 2nd February 1993, and the RX-5C Water-Air Pump Aerator, patented on 19th April 2001.
The water treatment system using trough plants in conjunction with an aerator helps increase oxygen in the water while setting up a plant trough to improve water quality. The system shows his royal determination to help better the lives of his royal subjects by improving water quality for a more sustainable life.
