Control of trichloroethylene emissions from sparging systems by horizontal bio- and chemo-barriers
Tezel, U; Demirer, Göksel Niyazi; Uludag-Demirer, S (Informa UK Limited, 2005-02-01)
The scope of this study was to develop a continuous system to clean-up a trichloroethylene (TCE) contaminated gas stream, where biotic and abiotic removal mechanisms are undertaken sequentially simulating the horizontal bio- and chemo-barriers proposed for the in-situ remediation of the contaminated sites. The bio- and chemo-barriers were simulated by using glass columns packed with granular anaerobic mixed culture and Fe(0) filings, respectively. The effect of gas residence time, which is adjusted by the g...

Control of flow structure on nonslender delta wing using passive bleeding: effects of orientation, angle, and solidity ratio
Yavuz, Mehmet Metin; Kestel, Kayacan (null; 2018-11-18)
Recently, we have demonstrated that the bleeding, which utilizes passages inside the wing to allow the fluid flowing from the pressure side to the suction side by using inherent pressure difference, could be used as an effective flow control method for nonslender delta wings. In the present study, this technique is investigated in detail for nonslender delta wings of 35 and 45-degree sweep angles in a low speed wind tunnel using smoke visualization, particle image velocimetry, and surface pressure measureme...
Regulation of crystal protein biosynthesis by Bacillus thuringiensis: I. Effects of mineral elements and pH
ICGEN, Y; Icgen, BÜLENT; Özcengiz, Gülay (Elsevier BV, 2002-11-01)
Crystal protein synthesis by a local isolate of Bacillus thuringiensis was monitored and compared in association with growth and sporulation in media differing in mineral element content. Mg and Cu were the most important metals for the biosynthesis of 135 kDa and 65 kDa toxin components in that the former was essential and the latter was greatly stimulatory at 10(-6) to 10(-7) M concentration. Also the inclusion of Mn favored toxin production at concentrations ranging from 3 x 10(-4) to 10(-5) M. The omiss...
Control of ph in neutralization reactor of a waste water treatment system using identification reactor
Obut, Salih; Özgen, Canan; Department of Chemical Engineering (2005)
A typical wastewater effluent of a chemical process can contain several strong acids/bases, weak acids/bases as well as their salts. They must be neutralized before being discharged to the environment in order to protect aquatic life and human welfare. However, neutralization process is highly nonاlinear and has timeاvarying characteristics. Therefore, the control of pH is a challenging problem where advanced control strategies are often considered. In this study, the aim is to design a pH control system th...
