Reaction Zone Modelling

For the reaction zone efficiency (dNfl/dt), defined as the reduction of number of primary particle flocs with time, floc and bubble size (dfl and db) and concentration are defined as relevant process parameters:

where apb = particle bubble attachment efficiency;

= total single collector efficiency; db = bubble diameter; vb = bubble rise velocity; Nfl = floc number concentration; ®b = bubble volume concentration.

Particle (floc)-bubble interception is considered to be the most relevant kinetic mechanism for DAF efficiency, depending on the floc and bubble size (dn and db) and incorporated in This term also considers floc-bubble collision mechanisms related to Brownian diffusion, settling and drag.

A summary of these parameters, their dependence on the system variables and desirable operational conditions is given in Table 1.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
