Waste systems

Based on the evidence that acceptable recycled petroleum products can be produced, there is a considerable legislative record encouraging the recycling of used oil. Starting with the Resource Conservation and Recovery Act in 1976 (20), used oil was held apart from the normal hazardous waste system because the oil was viewed as a valuable commodity. This was followed by the Used Oil Recycling Act in 1980 (33), which removed any federal requirement that lubricants containing re-refined base oil carry special labeling.

The third part, called the surface water collection and removal (SWCR) system, lies above the waste system in a cap or closure above the closed facility. Its purpose is to redirect surface water coming through the cover soil from the flexible membrane in the cap to the outside perimeter of the system. The location of all three parts of the liquid management system is illustrated in Figure 26.21. 

The induction periods for the reaction of sodium nitrate-bitumen mixtures (43 57 wt) heated at 195, 234 or 260°C are 44, 2 and 0.5 h, respectively. Further study of sodium nitrate/bitumenised waste systems held at these temperatures showed an initial weak exotherm around 260°C and a larger exotherm (0.96-1.21 kJ/g) accompanied by 50% wt loss around 430°C. 

Radioactive substances (radionuclides) are known health hazards that emit energetic waves and/or particles that can cause both carcinogenic and noncarcinogenic health effects. Radionuclides pose unique threats to source water supplies and chemical processing, storage, or distribution systems because radiation emitted from radionuclides in chemical or industrial waste systems can affect individuals through several pathways by direct contact with, ingestion or inhalation of, or external exposure to, the contaminated waste stream. While radiation can occur naturally in some cases due to the decay of some minerals, intentional and nonintentional releases of...

Based on information from the Eco Waste commercial pilot facility in 1995, costs for a full-scale SCWO unit were estimated to be 10 to 20 cents per gallon of waste treated (D11868N, p. 3). Detailed cost estimates are provided for the Eco Waste system (T0877), the Foster Wheeler system (T0314), and the General Atomics system (T0329).

The present study was initiated in order to obtain quantitative data on the relative adsorption potentials of metal ions in the region of the z.p.c. of hydrous manganese oxide. This information is of considerable importance in a variety of practical phenomena ranging from the mechanism of trace metal inclusion in ocean-floor manganese nodules and pisolitic manganese ores to the sorption behavior of manganese precipitates in natural water and waste systems.

Fly ash increases the density, decreases the permeability, and increases the leaching resistance of Ordinary Portland Cement (OPC). It is a truism that The leach resistance of solidified cement-waste systems can be improved by any process which accelerates curing, limits porosity, or chemically bonds fission product or actinide elements. (Jantzen et al., 1984). Supercritical C02 treatment of a modified Portland cement is expected to further increase the density over the untreated material, so that a reduced porosity and improved leachability should result. In addition, the high silica content of fly ash, with its well-known sorbent properties toward actinides and certain other radionuclides, enhances the immobilization characteristics. 

The first two of these parameters require a survey of the entire laboratory by the waste system manager. For small laboratories, a brief survey, which includes discussion with the individual(s) responsible for each segment of the operation, may suffice. For large, diverse departments it may be desirable to precede the survey with a simple questionnaire. It is almost inevitable that such a survey will uncover waste problems that must be solved at the outset, (e.g., caches of... 

Spent resin is transferred from the column through a 10-mm-diam tube to a resin storage tank. The flush water continuously overflows the storage tank through a screen to the ORNL Intermediate Level Liquid Waste System. 

The sequence of process steps shown in Fig. 4 produces three batches of spent resin (a total of about 4 L) and introduces about 50 kg of LiCl into the liquid waste system. The initial product recovery steps require about two weeks of operating time, and the clean rework recovery requires another 2 weeks. 

The cell voltage changed between 2.7 and 2.9 V. After an operation, the same reactor treated other waste systems successfully, also on a long-term basis. The data demonstrated that the Pd cathodes can be subjected for a relatively long HDH operation. 

Short-circuiting is one of the major problems associated with mechanical aeration equipment. Combined mechanical- and diffused-aeration systems have enjoyed some popularity for industrial-waste systems that treat variable organic loads. The mechanical mixers provide the fluid mixing with the diffused aeration varied for different oxygen-transfer rates.
