Coagulant
click for PDF
RoQuest® 6000 contains a blend of organic coagulants and ferric sulfate and is designed for use as a coagulant and flocculation aid in flocculator-clarifiers.
This product will enhance performance by removing colloids, silt, and many organic molecules, producing an effluent that is a more acceptable feedwater quality to downstream reverse osmosis membranes.
Performance:
RoQuest® 6000 provides unique performance and application benefits:
- Contains more than 9.5% soluble ferric ion and less than 0.2% ferrous ion.
- Certified by United Laboratories to ANSI/NSF 60 for use in systems producing potable water.
- Capable of producing RO quality feedwater in multimedia and sand filtration applications.
- Compatible with thinfilm (polyamide) and cellulose acetate RO membranes.
- Filter-aid properties resist solids breakthrough in direct filter applications.
- Low dosage requirements.
- Compatible with Vitec® 3000, 5000 & 7000 scale inhibitors.
- Effective over a wide pH range.
Use Instructions:
Inject RoQuest® 6000 at least 15 feet (5m) upstream of multimedia filters. Do not use static mixers ahead of the filters as the shear imparted by this equipment will degrade the polymers contained in this formulation.
Dosing Guidelines:
Typical RoQuest® 6000 dosage is in the range of 5 to 35 ppm. Approximately 0.25 ppm of alkalinity expressed as calcium carbonate is required per ppm of RoQuest® 6000. Following coagulant addition, a minimum of 25 ppm of residual alkalinity is required.
Significant overdosing of RoQuest® 6000 may cause degradation in the quality of the filtered water. If there are any questions, please contact Avista Technologies for specific dosing instructions.
Dilution:
RoQuest® 6000 may be fed neat if possible.If a dilution is necessary, dilute no more than 4 to 1 with RO permeate or DI water.
