Global Water & Energy (GWE), a member of Global Water Engineering Group of Companies, has used its technology to convert wastewater into biogas and remove 97% of organic matter at a brewery in Guatemala.
The brewery, Cervecería Centro Americana (CCA), which is based in Guatemala City, will treat its wastewater with a combination of GWE technologies in order to remove contaminants and generate green energy (or biogas) which could be used to power boilers or be sold back to the grid for a profit.
GWE’s new wastewater treatment system is designed to remove approximately 97% of Chemical Oxygen Demand (COD), a measure of the organic content in the water. It will produce up to 4,800 Nm³/d of biogas at 76% methane content, which is equivalent to more than 3,200 kg of heavy fuel oil/day.
CCA’s new wastewater treatment plant uses four GWE technologies: a SUPERSEP-DF downflow solids separator, an ANUBIX-T expanded granular sludge bed, a FLOTOXsystem, which incorporates a Moving Bed Biofilm Reactor (MBBR) and a SUPERFLOT solids separation system and an ODORIX Biofilter, which controls the odour and ensures efficient degradation of the odorous compounds, organic acids, and hydrogen sulfide.
