Dynamics of biofilm processes in an annular reactor
Biological fouling is a general term referring 1 to the undesirable development of biofilms on surfaces exposed to aqueous environments. In water distribution systems and heat transfer equipment, biological fouling can cause substantial energy losses resulting from increased fluid frictional …

An Investigation of the Hydrodynamic Effects of Enteromorpha clathrata Fouling on Hydrofoils
… investigation was to determine the effects of biological fouling on hydrofoils. NACA 4412 and 4415 hydrofoil models with 6 inch chord and 8 inch span were used in this study. A water tunnel facility was designed and constructed to perform the tests, and the results were verified using …

Assessment of ultraviolet light disinfection efficiency of advanced wastewater treatment plant effluent
… that change filter operation conditions. Rapid biological fouling occurred on the off-line banks. Inorganic fouling of on-line banks was minimal. Assuming a worst case UV transmittance (%) and required treatment dosage (mW-s/cm{dollar}\sp2),{dollar} treatment capacity of this 30-foot long, …

Application of mixed-integer programming in chemical engineering
… actions for heat exchanger networks subject to fouling. The Travelling Salesman Problem finds a plethora of applications in many scientific disciplines, Chemical Engineering included. None of the mathematical programming formulations proposed for solving the problem considers fewer than O(n^2) …

Engineering tough, hygroscopic, and active hydrogels for surgical simulation and anti-biofouling
… of contexts, including tissue engineering, anti-fouling, drug release, medical devices, and flexible electronics. The usefulness of hydrogels in these contexts stems from their structure, consisting of a 3D cross-linked polymer network containing mostly water. This structure leads to a material …

Characterization and modification of carbon composite electrodes towards more affordable biosensing applications and integration into fluidic devices
… detection due to their low cost, resistance to biological fouling, large electrochemical solvent windows, and ability to be patterned. However, they often suffer from poor electrocatalytic activity, inability to be molded, and need for complex modifications to effectively detect certain …

The effect of aeration and aerator design on the physical, chemical and fertiliser quality of cattle slurry
… prevail, resulting in the breakdown of biological compounds into noxious and toxic chemicals which are of primary concern in environmental pollution. The introduction of large scale anaerobic digesters on every firm is impractical, as extensive supervision of the digester is required. …

Functionalized High Aspect Ratio Cellulose Nanocrystal Filled Composites for Gas and Liquid Separations
… the membrane before use and susceptibility to biological fouling. One technique to mitigate issues with TFCs is to utilize the desirable properties of nanoparticles through their incorporation in the TFC selective layer to create thin film nanocomposite membranes (TFNs). CNCs were selected for …
