POLYOX™ and
UCARFLOC™ are effective flocculants for clays, silica, silt, paper fines, and more. They can help reduce the total amount of flocculant needed through their high efficacy. Often, only a few ppm is required, and adding in excess results in failure. Determining the optimal concentration is critical for flocculant performance and cost considerations.
Jar Test for Sedimentation
POLYOX™ and UCARFLOC™ can be mixed directly into turbid wastewater as a powder or mixed into potable water to create a stock solution.
Since the concentrations needed for benchtop testing are often very low, ranging from 1–100 ppm, measuring the appropriate mass of POLYOX™ and UCARFLOC™ for a 1-liter jar test may be smaller than the sensitivity of scales present in most labs. Presented below is a ladder study using 1-liter jars with stock solutions to determine the optimal concentration for sedimentation using
UCARFLOC™ 309. As observed, the jar containing 2 ppm UCARFLOC™ 309 provided the best sedimentation performance.
