Journal ArticleDOI
Design and performance of water recirculation systems for eel culture.
L.T.N. Heinsbroek,A. Kamstra +1 more
TL;DR: In this paper, the design and performance of four commercial-scale eel farms and one pilot-scale installation were evaluated based on the design concept of Bovendeur et al. ( Aquaculture, 63 (1987) 329).
Journal ArticleDOI
A modified method to determine biomass concentration as COD in pure cultures and in activated sludge systems
TL;DR: In this article, a simple technique to determine biomass concentration as chemical oxygen demand (COD) was developed as an alternative to the standard volatile suspended solid (VSS) method, which was tested with pure cultures of a filamentous microorganisms (Sphaerotilus natans), a floc-forming bacteria and activated sludges.
Journal ArticleDOI
Optimization of the operational variables of a medium-scale reactor for metal-containing wastewater purification by ferrite formation
TL;DR: In this article, the interference caused by metal-binding organic matter present in the wastewater was investigated and a three-level noise factor was introduced in order to find control factor levels that yield optimum process performance.
Journal ArticleDOI
Influence of relaxation modes on membrane fouling in submerged membrane bioreactor for domestic wastewater treatment.
Rasikh Habib,Muhammad Bilal Asif,Muhammad Bilal Asif,Sidra Iftekhar,Sidra Iftekhar,Zahiruddin Khan,Khum Gurung,Varsha Srivastava,Mika Sillanpää,Mika Sillanpää +9 more
TL;DR: It has been observed that cake layer resistance was minimum in MBR10+1.5 but pore blockage resistance was increased in all relaxation modes, and Relaxation modes were also efficient in removing irreversible fouling to some extent.
Journal ArticleDOI
Characterization of the products from the pyrolysis of sewage sludge in 1 kg/h rotating cylinder reactor.
TL;DR: In this paper, an experimental procedure was divided into three parts: (a) initial test using the temperatures of 450, 500, 550, 600 and 650 °C while the nitrogen flow, the centrifuge rotation and biomass flow were kept constant, (b) 24-1 fractional experimental design and (c) experiments exclusively for the characterization of gaseous fraction, using the temperature of 500, 600, 550 and 600 °C.
