RoQuest™ FS liquid coagulant contains ferric sulfate and is designed for use as a flocculant in direct filtration applications. This coagulant enhances filter performance by removing colloids, silt, and many organic molecules to produce an improved filtrate that will reduce downstream reverse osmosis (RO) and nanofiltration (NF) membrane fouling.VIEW ALL CHEMICALSVIEW SUPPORT SERVICES
- Contains more than 12% soluble ferric ion.
- Approved for offshore use.
- Filter-aid properties resist solids breakthrough in direct filter applications.
- Low dosage requirements and effective over a wide pH range.
- Capable of producing RO-quality feedwater in multimedia and sand filters.
- Compatible with polyamide and cellulose acetate RO membranes.
- Compatible with all Vitec™ antiscalants.

Selecting the right cleaning chemicals extends system run times between cleanings, reduces chemical costs and extends productive membrane life and overall system up-time.
Provides a cost-effective solution for biological fouling, which is one of the most challenging issues faced by operators of polyamide membrane separation systems.
Inhibits scale while also dispersing colloidal particles. The inhibition and dispersant properties of Vitec products help extend system run times, reduce cleaning frequency, and increase the productive life of RO elements.
