TP – 1195 An Introduction to Hazardous Water Testing for Precipitation/Coagulation/ Flocculation Treatment for Professional Engineers

Description

Treatability testing is required to obtain the following necessary design and operating parameters:
Optimum pH levels for maximum removal of target metals.
Chemical reagent dosage rates and application points.
Mixing requirements.
Settling rates.
Sludge volume.
Sludge characteristics.

Before bench-scale testing begins, representative influent samples should be analyzed for the following parameters:
pH.
Temperature.
Total suspended solids (TSS).
Total dissolved solids (TDS)—including specific heavy metals and respective concentrations.
Oil and grease (O&G).
Alkalinity.
Conductivity (TDS).
Turbidity.Note that many vendors of pre-packaged P/C/F treatment systems offer treatability testing capabilities.
