An industry is discharging an acetic acid waste stream. (Recall that acetic acid is CH3COOH). Its natural pollutant discharge elimination system permit requires pH>4 and total organic carbon TOC < 250 mg/as C. What is the maximum strength of acetic acid waste ( as TOC in mg/L) that can be discharged without violating either permit requirement? ( recall that TOC in mg/L , measures the number of miligrams of carbon per liter)
