This Excel spreadsheet has worksheets for calculating equilibrium values and design values for precipitation of seven metals from wastewater, based on user input values for several parameters . You can buy a convenient metal hydroxide preciptiation spreadsheet for a very reasonable price. It is available in either U.S. units or S.I. units. Read on for background information about a Wastewater Metal Precipitation Spreadsheet.
Background for a Wastewater Metal Precipitation Spreadsheet
To make calculation for metal hydroxide precipitation from wastewater, data for the solubility of that metal vs pH can be used to obtain an equation for the metal hydroxide solubility as a function of pH. An example graph for zinc solubility vs pH is shown below.
Using an equation like that shown on the graph, equilibrium values can be calculated for effluent metal concentration, chemical usage and solids production. Application of a safety factor will give design values for effluent metal concentration, chemical usage and solids production.
