Abstract: A bag and a carrier therefore, the carrier comprising a base member having first and second pivotable wheels mounted proximate a first end of the base member, a third wheel mounted proximate a second end of the base member, the bag being mounted to the base member at the first end, the base member being pivotable with respect to the bag such that the base member can pivot between a first position wherein the base member lies adjacent the bag and a second position wherein the bag is supported on the base member, a handle arrangement extending upwardly from the base member and being operative to steer the first and second wheels, and a locking device to lock the pivotable wheels in a non-pivotable position when the base member lies adjacent the bag. The base member can function as a scooter type of device.

Abstract: A wastewater treatment process wherein a portion of a mixture of influent waste water and biomass are transferred from a first anaerobic region to a second anaerobic region having a relatively long retention time in order to produce additional very short chain fatty acids therein which are thereafter returned to the first anaerobic region so that biomass therein takes up the very short chain fatty acids. The contents of the first anaerobic region thereafter flow downstream into an aerobic region wherein the biomass takes up phosphorus. A portion of the biomass is returned to the first anaerobic region and a second portion of the biomass is wasted with phosphorus therein, thereby removing phosphorus from the wastewater being treated.
