 ==Main Processes==
-Main processes in SedimentQuality are organic matter mineralization, nitrification, denitrification and immobilization driven by microorganisms. These processes and microorganisms death are simulated using a standard rate (s.day-1.pop-1) that is afected by temperature, pH, oxygen in case of aerobic processes and sustrate concentrations if exist.
+Main processes in SedimentQuality are organic matter mineralization, nitrification, denitrification and immobilization driven by microorganisms. These processes and microorganisms death are simulated using a standard rate (s.day-1.pop-1) that is afected by temperature, pH, oxygen in case of aerobic processes and substrate concentrations if exist.
 An old formulation based on RZWQM was adapted in order to be consistent in units and in the new formulation a maximum rate exists and "stress" factors (from 0 to 1) are computed accordingly to pH, aerobiose and aerobiose conditions, oxygen and susbtrate availability. Aerobiose and aerobiose conditions are computed from realtive water content.

 '''OxygenTerm and Sustrate in non death rates'''
 The oxygen term and substrate term represent the abundance of substance that has not a negative effect on high concentrations. As so, for higher concentrations than optimum the value will be always 1. for lower concentrations than optimum there is a linear decrease of the term up to zero concentration and zero term.
-In the case that oxygen term is used in death rates it will become (1 - OxygenTerm) since term the value 1 represents a maximum death rate and 0 represents no death.
+In the case that oxygen term is used in death rates it will become (1 - OxygenTerm) since the value 1 represents a maximum death rate and 0 represents no death.
