Avista™| Filtration Study
The Avista™ Filtration Study helps determine the most efficient and cost-effective dosage of RoQuest™ coagulants for site-specific feedwaters.
The multimedia filtration (MMF) laboratory analysis uses particle counts, zeta potential, and turbidity to characterize a water sample for colloids and silt and determine its fouling potential. The analysis can be done on feedwater or filtrate to gain a better understanding of the foulant parameters.
