Global Water Engineering (GWE) represented in Australia by CST Wastewater Solutions has achieved international recognition for an Asia-Pacific cassava plant wastewater project that uses advanced technology to reduce pollution, save power and enhance profitability.
GWE installed a wastewater treatment plant for Chokyuenyong Industrial at its cassava production plant in Thailand. GWE’s wastewater technology helped the plant cut effluent COD pollution levels by more than 95% while extracting gas from wastewater to power the plant’s boilers and generate electricity.
GWE’s achievement was recognised at this year’s Global Water Awards in Berlin, where its CEO Mr Jean Pierre Ombregt received Highly Commended recognition for the installation.
GEW’s wastewater installation provides an international model of how it is possible to attain top environmental standards of wastewater cleanliness while generating green power and carbon credit profits as well.
Established in 2005, the Global Water Awards recognise outstanding achievements in the International Water Industry.
GWE has completed more than 300 water and wastewater projects across Asia, Africa, North and South America, Australia, China, Europe (including Eastern Europe) and Russia.
GWE has successfully built and commissioned more than 75 biogas utilisation systems for clients worldwide, including most recently in Australasia at the new Bluetongue Brewery in NSW. The biogas and wastewater technology has wide applicability throughout Australasia.
Highlights of the Chokyuenyong installation:
- Cut COD pollution level of influent wastewater from 22,500 ml/l to less than 1125 mg/l, resulting in cleaner discharges to treatment ponds and the environment
- Returns up to 2.7 Mw of electricity a year to a provincial power grid, PEA
- Saves the equivalent of up to 21,000 litres a day of fuel oil by producing up to 34,000 Nm³ of biogas
- Biogas is used to power the boilers and heating equipment used extensively in cassava drying and processing as well as generate electricity for the rotating equipment used in processing
- Generates carbon credits under the UN Framework Convention on Climate Change
