Biofouling is a major reason for flux decline in the performance of membrane-based water and wastewater treatment plants. Initial biochemical characterization of biofilm formation potential and biofouling on two commercially available membrane surfaces from FilmTec Corporation were investigated without filtration in laboratory rotating disc reactor systems. These surfaces were polyamide aromati...

Acrylated glyphosate was blended into a model polyolacrylate formulation and copolymerized. The resulting copolymer retains herbicidal activity similar to that of the monomer as indicated by the results of biological tests. No release of biocide from the coating was observed. The potential value of these biologically active acrylic formulations as biofouling compositions has been demonstrated b...

The biofouling affinity on different polymeric surfaces (PP, PSU, PET, PEEK) in comparison with SS 1.4301 was studied using the model bacterium E.coli K12 DSM 498. A test rig with seven identical chambers allowed investigations at different system conditions (throughputs, inclination of the heat transfer cell, etc.). The biofilm mass deposited on the polymer surfaces was several magnitudes smal...

Membrane filters are excellent prospects for increasing global access to safe water; however, they significantly limited by fouling, particularly biofouling. Fouling plagues membranes reducing efficiency and maintenance costs. Biofouling is problematic due the self-replicating nature of microorganisms secretion extracellular polymeric substances that make biofilm difficult remove. Living filtra...

Unsustainable harvesting of natural fish stocks is driving an ever growing marine aquaculture industry. Part of the aquaculture support industry is net suppliers who provide producers with nets used in confining fish while they are grown to market size. Biofouling must be addressed in marine environments to ensure maximum product growth by maintaining water flow and waste removal through the ne...

Effective and ecofriendly antifouling (AF) compounds have been arising from naturally produced chemicals. The objective of this study is to use cyanobacteria-derived agents to investigate the role of acetylcholinesterase (AChE) activity as an effect and/or mode of action of promising AF compounds, since AChE inhibitors were found to inhibit invertebrate larval settlement. To pursue this objecti...

Biofouling is a serious problem in marine aquaculture and it has a number of negative impacts including increased forces on aquaculture structures and reduced water exchange across nets. This in turn affects the behavior of fish cages in waves and currents and has an impact on the water volume and quality inside net pens. Even though these negative effects are acknowledged by the research commu...
