Floc Aggregated solid (biomass) particle Glossary of terms 313 Flux (or permeate The quantity of material passing through a unit area of velocity) membrane per unit time Flux-step Critical flux identification method whereby flux is incrementally increased and the TMP or permeability response recorded Fouling Processes leading to deterioration of flux due to surface or internal blockage of the membrane Gas/air sparging Introduction of gas/air bubbles Gas/air-lift Lifting of liquid using gas/air Gel layer Precipitation of sparingly soluble macromolecular species at formation membrane surface Heterotrophic Requiring an organic substrate to get carbon for growth and development Humic matter Organic matter of terrestrial origin Hydraulic loading rate Rate at which water enters the reactor Hydrogenotrophic Feeding of hydrogen Hydrophilic Water-absorbent Hydrophobic Water-repellent Inoculum Medium containing micro-organisms initially introduced into a reactor to establish new populations and start the biotreatment process Intensive/ Cleaning with aggressive chemicals to recover membrane recovery clean permeability Irrecoverable fouling Fouling which is not removed by physical or chemical cleaning Irreversible/ permanent fouling Fouling which is removed by chemical cleaning Lumen-side Inside the fibre/filament/lumen Macropore Pore with diameter above 50 mm Maintenance Cleaning with less aggressive chemicals to maintain cleaning membrane permeability Membrane packing density Membrane area per unit volume Mesophilic Thriving at intermediate temperatures (20–45°C, 15°C optimum)
314 The MBR Book Mesopore Pore with diameter between 2 and 50 mm Methanogens Microorganisms producing methane as a metabolic byproduct Micropore Pore with diameter below 2 mm Mist flow Air/liquid two-phase flow where the air is the continuum Modularisation Based on modules: Using more modules at higher flows, rather than increasing the unit process size Module (membrane) See Appendix D Monod kinetics Kinetics defining biomass growth and decay during biotreatment Nitrification Biochemical oxidation of ammonia to nitrate (Organic) loading rate Rate at which (organic) matter is introduced into the reactor Panel FS membrane element Percolation Theory defining probability of water flowing through a theory medium containing three-dimensional network of interconnected pores Permeability Ease of flow through membrane, represented by flux:pressure ratio Permeate Water or fluid which has passed through the membrane Perm-selectivity Permeation of some components in preference to others Plate-and-frame Synonymous with “flat sheet” Pleated filter cartridge Type of flat sheet module Plug flow Flow in which no back-mixing or dispersion occurs along the length of the pipe or reactor Pore plugging Type of membrane fouling (by blocking of pores) Porous Membrane of low selectivity operating by physical straining membrane alome Psychrophilic Thriving at relatively low temperatures (0–20°C) Rack See Appendix D Recovery or conversion Fraction of feed water converted to permeate product Reduction- Conditions defined by the presence of either dissolved oxidation oxygen or some other species capable of providing oxygen (Redox) conditions for bioactivity
