A safety blade magazine for storing, transporting and dispensing individually a large number of single edge safety blades. The magazine is essentially an elongated rectangular box having an opening or slot at the base of one wall and a thumb shaped recess along the bottom wall for dispensing a single blade at a time out of the slot in the bottom of the box. The magazine also includes an elongated spindle centrally disposed from its top to within one blade width of the dispensing slot in length, the spindle capable of holding one hundred razor blades through the blade apertures in the center of the single edge blades. A small magnet is disposed on the outside wall just above the dispensing slot which acts to stabilize the blades in the magazine and also to assist in dispensing whenever the thumb actuated recess to manually dispense the blades is utilized. Finally the magnet serves to temporarily hold a blade that has already been dispensed. The safety blades are installed in the box at the factory on the spindle and the spindle top wall and a side wall are then joined to the remainder of the box which is then taped in a closed position. The spindle may include a washer-like lock that rests upon the blades to keep them together on the spindle.

In a process for biotreating industrial waste water, a portion of the effluent is treated with activated carbon and recycled to the biotreater. This results in a substantial improvement in the biotreater performance. In another embodiment, the biotreatment is an activated sludge process and the clarifier effluent is filtered to stop loss of bacteria and periodically the filter is backwashed to return the bacteria to the system.
