Fluidized sand-beds are efficient and cost-effective methods for biological treatment within recirculating aquaculture systems, and have recently been the topic of considerable research. However, their hydraulic design has been largely undescribed in

The effect of low water temperature on flocculation kinetics was examined using ferric nitrate to coagulate kaolin clay in water under tightly controlled treatment conditions. Both the particle size distribution data obtained from an automatic image

Many utilities are concerned about the performance of their treatment systems as a result of recent Cryptosporidium outbreaks in the United States and Canada. The most responsive course of action a utility can take at this time is to ensure that its

One of the primary objectives of the research described here was to identify the best available measure of the intensity of turbulence with a view to correcting the mixing intensity of the flocculation process to compensate for temperature effects. I

Reasons for the renewed interest in granular filter backwashing are presented, especially the more difficult backwashing problem encountered in wastewater filtration. Water fluidization backwash alone is inherently weak because of the absence of part

A major problem in designing water pollution control plants is sizing units to have adequate capacity to treat peak flow rates and waste loads without process failure or significant loss in performance. A case study of a midwest city is used as a bas

The familiar Camp-Stein equation for the root-mean-square velocity gradient G is widely used in the design of rapid mixing and flocculation facilities. The literature related to turbulent phenomena, power required in turbulent mixing, turbulent flocc
