Yd. of soil, again significantly less than incineration. Liquids/Solids Treatment Systems (LSTS) These are hybrids, intermediate between land treatment and conventional water-suspended biological systems. The waste is not in a solid form as in land treatment, nor in water as in conventional municipal wastewater treatment, but half way between. The wastes are in a suspended solid, slurry or sludge form. LSTS systems reduce the level of contaminants in a waste primarily by 1) dissolving the organics, 2) biodegradingthe dissolved organics into less toxic and less environmentally significant forms, and 3) releasing the products as gases to the atmosphere.

Steel has historically been heavily concentrated in Pennsylvania and Ohio. New York has unusually large concentrations of many small electroplaters in the New York City area, leather tanneries in two Mohawk River Valley counties, and a large number of diverse, old manufacturing operations in the Buffalo area and Elmira areas. S. is from industry which is responsible for 69%. Municipal output accounts for 35% The bulk of potentially hazardous waste is generated from four industries: primary metals; organic chemicals and explosives; electroplating and metal finishing; and inorganic chemicals.

Column systems are nitrogen gas packed beds, submerged high porosity packed beds, and submerged high porosity fluidized bed systems. Since there is a variety of media used to measure reactions, general design criteria for these systems is not readily available. In order to size the reactor volume, one approach is to estimate the level of biomass on the media surface and then use measured reaction rates per unit of biomass to obtain the nitrogen removal capacity of the column. This is best done through p,ilotplant experiments.
