Industrial aquaculture wastewater contains large quantities of suspended particles that can be easily broken down physically. Introduction of macro-bio-filters, such as bivalve filter feeders, may offer the potential for treatment of fine suspended matter in industrial aquaculture wastewater. In this study, we employed two kinds of bivalve filter feeders, the Pacific oyster Crassostrea gigas an...

The present work reports results of an effort to produce a stack multilayer optical filter on a poly(ethylene terephtalate) (PET) substrate, using a PECVD technique. Titanium dioxide type of material (n550 = 2.3) has been selected for high refractive index layers while that of silicon dioxide type (n550 = 1.4) served as low refractive index films. For a synthesis of the former material, titaniu...

Deposition of particles while flowing past constrictions is a ubiquitous phenomenon observed in diverse systems. Some common examples are jamming salt crystals near the orifice saltshakers, clogging filter systems, gridlock vehicular traffic etc. Our work investigates deposition events colloidal microspheres over microstructured barriers microfluidic devices. The interplay DLVO, contact and hyd...

The properties of electronic devices based on carbon nanotube networks (CNTNs) depend on the carbon nanotube (CNT) deposition method used, which can yield a range of network morphologies. Here, we synthesize single-walled CNTs using an aerosol (floating catalyst) chemical vapor deposition process and deposit CNTs at room temperature onto substrates as random networks with various morphologies. ...

A field study was conducted to explore the suitability of 5 pesticide deposition samplers for airborne spray and ground deposits from ultra-low-volume (ULV) space sprays. Samplers included horizontally stretched stationary cotton ribbons at 2 heights, rotating ribbon, rotating Teflon slides, and filter paper. Slides were also used for droplet-size analysis. A set of 7 samplers of each type was ...

An experimental investigation of the cake filtration behaviour of 125-180 pm polyethylene particles, suspended in a neutrally buoyant Newtonian fluid, has been carried out. Static cake filtration measurements of both filtrate volume out-flow and cake thickness kinetics show the familiar t”” time dependence. In addition, the hydraulic resistance of the cake was found to be pressure independent, ...
