Technological line

The experimental plant consists of two technological lines of equal purpose and construction. 

Comprehensive genomic research therefore necessitates a combination of several advanced techniques (technologies) which would form more complex technological lines. An example of such solutions may be found in recent scientific papers (Pawliczak and Shelhamer, 2003 Braga-Neto and Marques, 2006) ... 

However, on account of the wide range of industrial and agricultural wastewaters it is impossible to design universal technological lines for these types of wastewaters. 

Industrial wastewaters are noted for a considerable time variability in both quality and quantity. Therefore, standardization of the quantity and the quality is the essential precondition of optimization of the whole treatment process, and this must include coping with emergency situations and must provide a constant treatment effect. Because of this, equalization basins with a sufficient time interval of dwell are situated at the beginning of the technological line. 

A technological line of wastewater treatment plants involves some of the following processes or their combinations quantity and quality equalization, straining, sedimentation, flotation, physico-chemical and chemical treatment, natural biological treatment, activation, bioflltration, after-treatment of biologically treated wastewaters and disinfection [23-27]. 

The aim of selection of appropriate processes is to achieve the required water quality by employing a technically, economically and operationally simple technological line involving the minimum introduction of other substances into the treated water. 

The system operates as a rotary drum screen with continuous washing to prevent clogging of the meshes (Fig. 3.48). Such systems are part of a technological line as a substitute for sedimentation in the case of waste-water purification they can replace flotation equipment. The efficiency of separation carried out in this way is about 60%. 

Depending on the quality of suspended material and on their location in the technological line, settlers can be classified into primary and secondary types. 

The primary settlers are installed at the beginning of the technological line, usually after the rough pre-treatment, or after coagulation.

Several reactor design have appeared in the SMR range that use Heavy Water as a moderator (e.g. CANDU 3, CANDU 6, PHWR 500, PHWR 220). The main features of this technology line is ... 

The HTGR technology line utilizes complete passive system for RHR and shutdown. Residual heat is taken away by radiator surrounding the reactor pressure vessel utilizing namral circulation. Shutdown is accomplished by simply dropping small absorber spheres by gravity force. 

These three main lines, as defined by their primary coolant are water cooled, gas cooled, and liquid metal cooled. Water cooled reactors can be fiirther categorized as heavy water or light water moderated reactors. The design approach for a given system can be substantially different from another system within the same technology line. The small and medium reactor area has to deal with all technological lines and all varying approaches. The relevant reactor information for the purpose of this TECDOC has been divided into six parts ...
