Problem 2. A municipal wastewater sample is examined for its solid contents. Some solid parameters measured are given below: Organic Total Solids (OTS) =200mg/L Organic Total Suspended Solids (OTSS) =50mg/L Inorganic Total Dissolved Solids (ITDS) =100mg/L If 20% of Total Solids (TS) is assumed to be inorganic total suspended solids (ITSS), calculate the concentration of: a) Total Dissolved Solids (TDS) as mg/L. (5p) b) Total Suspended Solids (TSS) as mg/L. (10p) c) Total Solids (TS) as mg/L. (5p)
