RoQuest-3000

Summary

Product identification

• Product Name: RoQuest® 3000
• Type: Liquid coagulant
• Description: A multicomponent polymer coagulant formulated for membrane use, designed for particle-laden borehole sources or treated municipal supplies. It enhances filter performance by reducing turbidity and color, especially in multimedia and sand filters.
• Trademarks: RoQuest®, Vitec®

Operating limits

• Feedwater Turbidity: Upper limit of 2.0 NTU for raw waters.
• Feedwater Color: Upper limit of 10 units for raw waters.
• pH Range: Effective over a wide pH range.

Feed water

• Best results achieved with: Municipally treated feedwaters and raw waters with relatively low concentrations of particulates and organic color.

Product water

• Capable of producing: RO quality feedwater in multimedia and sand filters.

Electrical

• NSF/ANSI 60 Certified: Yes

Mechanical / hydraulic

• Injection Point: Inject at least 15 feet (5 m) upstream of multimedia filters.
• Mixing: Do not use static mixers ahead of filters.
• Typical Dose: 0.5-4.0 mg/l. Refer to RoQuest Coagulants Selection Guide and Avista Advisor for specific dosing.
• Dilution: Can be diluted at a rate of 25:1 using dechlorinated water prior to injection to improve effectiveness, but not generally necessary.
• Overdosing: Significant overdosing may cause degradation in filtered water quality.

Specifications

• Appearance: Clear, colorless to amber liquid
• pH (1% solution): 4.0-6.0
• Specific Gravity (@25°C): 1.0-1.1

Performance benefits

• Filter-aid properties resist solids breakthrough in direct filter applications.
• Low dosage requirements and no minimum alkalinity.
• Internal biostat inhibits biological growth in the drum and feed tank.
• 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 and Avista antiscalants, including Vitec® 3000, 3025, 5000, 5100 and 7000.

Packaging and Storage

• Available Formats: Pail (45 lb / 23 kg), Drum (475 lb / 220 kg), IBC tote (2200 lb / 1000 kg). Drumless or bulk tanker delivery available on request.
