Posttreatment design

Solidification/Stabilization technologies are techniques designed to be used as final waste treatment. A major role of these processes is posttreatment of residuals produced by other processes such as incineration or chemical treatment. In some cases, solidification/ stabilization processes can serve as the principal treatment of hazardous wastes for which other detoxification techniques are not appropriate. High volume, low toxicity wastes (such as contaminated soils) are an example of this application. [Pg.176]

If before-treatment (pre-restoration) monitoring cannot be performed, it is stiU possible to use a post-treatment design. This monitors the restored reach and untreated reaches that resemble the treated reach after the restoration was carried out. Roni et al. [11] discuss two types of post-treatment design intensive posttreatment, in which multiple years of data are collected at one or more paired control and treatment sites and extensive post-treatment, in which many paired treatment and control sites are sampled once each over a 1-3-year period. Whichever design is used, the monitoring will depend on available financial resources, but should reflect the restoration objectives. [Pg.252]

This in vitro cytogenetic test is a clastogenicity test system for the detection of chromosomal aberrations in cultured mammalian cells or primary cultures. Chromosomal aberrations may be either structural or numerical. However, because cytogenetic assays are usually designed to analyze cells at their first posttreatment mitosis and numerical aberrations require at least one cell division to be visualized, this type of aberration is generally not observed in a routine cytogenetic assay. The best estimate of aberration frequency is the first cell division after the start of treatment. Structural aberrations are of two types chromosome or chromatid aberrations. [Pg.836]

Pretreatment and Posttreatment - Some materials may require pretreatment processing to prepare the material for extraction or post-treatment of the residue after extraction is completed. Material handling systems such as conveyors and product silos must be designed with these considerations in mind. [Pg.142]

This graph type could also prove useful for each hour posttreatment administration in a thorough QT design. [Pg.206]

For the development of design surface, a distinction between the pre-and posttreatment of mold cavity surface and pure pre-treatment for coating (e.g., eroded mold surfaces) has to be done. For the design development, processes such as micro-radiation, mat-down treatment, or micro mat can be used. Depending on the technology used, as shown in Figure 2.110, paint-like or very dull surfaces can be established. [Pg.432]
