GEM System - Smaller Footprint
With the GEM System, the entire wastewater stream is treated in the LSGM heads before it reaches the floatation tank. By the time the stream is ejected into the tank from the last LSGM head, it is in the form of treated water and buoyant flocs. The flocs float independently and automatically float to the top of the tank. The tank is used only for skimming the flocs off of the surface of the water.
Since the tank is only used for skimming, the size of the tank is only determined by the maximum flow rate of the GEM System itself. If contaminant loading increases, it is not relevant to the sizing of the tank. The GEM System eliminates retention time considerations in reference to contaminant loading, as no aeration “contact time” is needed. This allows the GEM System to adapt to a wide variety of flows and high contaminant loadings.
Since the floatation tank is only used for skimming the flocs off of the surface, and is not based on the contaminant loading level, the GEM System is able to utilize the smallest tank volume possible for the given flow rate.
All of our customers who have replaced DAF systems with the GEM System have increased flow handling capacity and increased contaminant loading capacity while doing so in a much smaller space.
