Aerobic granular sludge is a promising alternative to traditional activated sludge basins in wastewater treatment plants (WWTP). Granular sludge has much better settling characteristics than activated sludge. Furthermore it can remove carbon, nitrogen and ...
Plasma enhanced chemical vapour deposition (PECVD) of thin films such as amorphous silicon has widespread applications especially in the field of photovoltaic solar cells and thin-film transistors for flat screen production. Industrial applications require ...
A novel concept of a recycle loop reactor is developed with structured filamentous catalysts integrated as trays in a staged bubble column. The reactor can be operated in batch or continuous mode. Woven fabrics of activated carbon fibers (ACF) were used as ...
Ultrasound propagates through an elastic medium at a rate or speed named the ultrasound propagation velocity (UPV). This velocity is detd. by the rate at which the wave energy is transmitted, inversely related to the square root of the d. and compressibili ...
An invasive plate and frame capacitance probe was designed for dielec. const. measurements over a wide frequency range (10-5000 kHz) in a 5-L stirred-tank reactor. Preliminary measurements with polyethylene beads showed a linear variation of the effective ...
Aerobic granular sludge-based reactors represent an attractive alternative to conventional activated sludge systems due to their small footprint and their low energy consumption and excess sludge production. The granules developed in such systems have high ...
Aerobic granular sludge-based reactors represent an attractive alternative to conventional activated sludge systems. Compared to activated sludge, the use of aerobic granular sludge reactors is advantageous because (i) considerably less area is required fo ...
Compliance with the U.S. drinking water standard for arsenic (As) of 10 μg L-1 is required in January 2006. This will necessitate implementation of treatment technologies for As removal by thousands of water suppliers. Although a variety of such technologi ...
The stereospecific hydrolysis of phenylalanine esters by chymotrypsin can avantageously be undertaken in aq.-org. 2-phase systems. The partitioning of the deprotonated form of the substrate changes the pH characteristics of the reaction system drastically. ...
A method is proposed of correcting the design of countercurrent sepn. columns for the impact of axial-dispersion effects. After computing the required no. of transfer units (NTU) employing conventional procedures based on the plug-flow assumption, the meth ...
