Anti-Fouling Features on Trays

Fouling and Fouling Mitigation on Heat Exchanger Surfaces

Nanoporous anti-fouling silicon membranes for biosensor applications.

The ability to create biocompatible well-controlled membranes has been an area of great interest over the last few years, particularly for biosensor applications. The present study describes the fabrication and characterization of novel nanoporous micromachined membranes that exhibit selective permeability and low biofouling. Results indicate that such membranes can be fabricated with uniform p...

Active Anti-fouling and Defouling of Membranes using Electrochemical Methods

Industrial wastewater treatment from cattle slaughterhouses traditionally use dissolved air floatation (DAF) to remove the high organic content of fat, oil and grease (FOG) from wastewaters and recover them for producing other products, including tallow, gelatine and food additives. Dissolved air floatation presents several operating difficulties including the large size, high energy use and od...

Living with biofilms - elements of an integrated anti - fouling strategy

Biofouling“ is referred to as the unwanted deposition and growth of biofilms. This phenomenon can occur in an extremely wide range of opportunities ranging from colonization of medical devices, production of ultrapure, drinking and process water, fouling of ship hulls, pipelines and reservoirs. It seriously damages the efficacy of membrane processes by forming a secondary membrane which, at a c...

Improved High Performance Trays

From a design and hydraulic standpoint, trays are relatively complex distillation internals. In the ongoing search for higher performance trays, one first must understand the hydraulic and mass transfer aspects of the tray operation such as entrainment, downcomer flooding, and vapor liquid contact. When this is well understood, then various aspects of the deck and/or downcomer designs can more ...
