Secondary Treatment of H2O ~ involves the use of microbes to remove organic material from the liquid portion of the sewage Tertiary treatment ~ involves the removal of inorganic materials thru chemical means Disinfection ~ disinfect the water to remove all microbes Biological oxygen demand (BOD) ~ a measure of the amount go dissolved O2 required by aerobic biological organisms in the H2O to break down the organic material the greater the BOD->the greater the stress on mari...

Microorganisms/Microbes - -Small living organisms that can't be seen by the human eye - diverse in form/funtion - inhabit every EVR that supports life - many single celled, some form complex structures, some multicellular - live in microbial communities Microorganisms/Microbes - - oldest form of life - major fraction of earth's biomass - surround plants and animals - affect human life (infectious diseases, food and water, soils, animal health, fuel) tools for studying microorganisms -...

MCB 3020 exam 2 Questions And Answers 100% Correct 1st law of thermodynamics Energy cannot be created or destroyed, but can be redistributed within a system or its surroundings. Free energy energy that is available to do work. It is defines at standard conditions of concentration, P, T, and pH. the more (-), the more energy we have to do work (exergonic) Standard reduction potential The tendency of a species to be reduced. in ETC, electrons flow from low to high reduction potential. (...
