(HP-65) Prog. No. 04198A Reverse Osmosis
Extract from Aircraft Industry Wastewater Recycling, EPA-600/2-78-130 (1978/06), Appendix D: Calculator Program for Computing Reverse Osmosis Unit Product and Concentrate Concentrations, pgs 69-71

     "The general problem of calculating concentrate concentration and permeate concentration in an unit employing feedback is best solved by a reiterative technique. Such calculation is time consuming unless a computer or programmable calculator is available. This appendix contains a 99-step program devised for use on a Hewlett-Packard HP-65 calculator, that reiterates the necessary calculations until two successive results differ by less than one part in 1000".
