This innovative process has been proven in successful laboratory trials on customer effluent samples, pilot-plant studies at customer sites and commercial (full scale) installations.
These have shown the ACCENT™ process successfully oxidizes a wide range of organic compounds including:
Johnson Matthey has investigated generic effluents from process industries at both laboratory and scaled-up on-site pilot-plant testing, enabling us to predict the selectivity and therefore viability for a particular effluent stream. At pilot-plants at a number of customer sites, ACCENT has demonstrated its success at eliminating non-biodegradable organic compounds from chemical, agrochemical and pharmaceutical manufacturing waste.
The experimental results indicate the degree of treatment achievable and allow an estimate to be made of the catalyst volume and hence capital cost, plus hypochlorite and caustic usage.
Results from customer trial on waste phenol stream
Decolorization trials on dyehouse retentate waste (post reverse osmosis unit)
This test demonstrated the controllable decolorization and COD reduction of the stream allowing recycle of the process water
