Appropriate technology

In addition to the reported economic reserves, there are substantial nickel resources which could be amenable to mining and refining once appropriate technology becomes available. The single largest such resource is seabed nodules which contain ca 1% nickel and which could represent up to 800 X 10 t of nickel (see Ocean rawmaterials). 

Select the appropriate technology and topology for your application. 

In the U.S. and many parts of Western Europe, 95% destruction of VOC is required, and when toxic chemicals are present the destruction efficiency is raised to 99%. Characterization of the VOC laden stream assists in selecting the appropriate technology to achieve the required destruction efficiency. 

This logical process ensures that all appropriate technologies are identified and evaluated on an equal basis. 

A wide range of technologies for the reclamation of wastewater for reuse is available (Fig. 2). The choice of the appropriate technology for a given project... 

Appropriate Technology that is Adapted to the social, political, and cultural Context. 

The design and performance of the anaerobic treatment processes that we have discussed are shown in Table 30.3. According to the table, the AFBR outperforms the UASB and the AF. An AFBR can achieve higher removal efficiency within a shorter HRT. The volumetric loading rate of the AFBR is comparatively higher than that of the UASB and AF. However, the choice of appropriate technology should consider factors such as the footprint, operational and maintenance cost, and the level of treatment required. 

Pretreatment is necessary for the treatment of the food industry wastewater. Pretreatment options such as flow equalization and neutralization, screening, FOG separation, acidification, coagulation-flocculation, sedimentation, and DAF are available. Selecting the appropriate technology depends on the wastewater characteristics. 

Recent advances in chemical plant safety emphasize the use of appropriate technological tools to provide information for making safety decisions with respect to plant design and operation. 

Safety or loss prevention the prevention of accidents through the use of appropriate technologies to identify the hazards of a chemical plant and eliminate them before an accident occurs. 

Control application of appropriate technology to reduce workplace exposures to acceptable levels. 

After potential health hazards are identified and evaluated, the appropriate control techniques must be developed and installed. This requires the application of appropriate technology for reducing workplace exposures. 

In determining the most appropriate technology to controlling a process stream, it is necessary to characterize the airstream. The first step in the characterization is to establish what organics and other contaminants need to be destroyed... 

The choice by a company for a sustainable or a petrochemical source of an ingredient will depend on various aspects, but cost will be the primary driving force. Availability of a low-cost feedstock is crucial, but also the available and appropriate technology in the company will have a large influence on this decision.
