BACKGROUND
A chicken processing facility was facing serious wastewater treatment challenges at its Perth site. Its undersized and underperforming system was no longer sustainable, causing a health & safety hazard and an odorous working environment. The poor performance of the waste water system was affecting production capacity and site restrictions limited space for a new plant. The customer engaged MAK Water in an extended consultation process, looking for improved flotation and flocculation technology.
Clean Water Technology’s (Gas Energy Mixing) GEM® system is an innovative and patented approach to wastewater treatment. This superior flocculation and floatation system delivers results significantly better than conventional Dissolved Air Floatation (DAF) and alternative wastewater treatment technologies. The GEM-DAF System removes higher levels of contaminants than conventional DAF systems, using less chemicals, while generating significantly drier sludge. A GEM-DAF System footprint can be over 50% smaller than a typical DAF of similar capacity.
The GEM System uses unique hydro-cyclone technology in the Liquid, Solid, Gas Mixing Heads (LSGM) In these heads, chemistry is injected and air is dissolved into 100% of the wastewater stream while creating a vortex. The random flocculation and flotation process of a DAF system becomes a managed process in the GEM System resulting in the removal of more contaminants and drier sludge.
