RoQuest® 3000
Organic Coagulant
click for PDF
RoQuest® 3000 contains a blend of organic polymers and is designed to be injected into the feedstream of multimedia and sand filters. This product will enhance the filter performance by further reducing turbidity and color, producing an effluent that is a more acceptable feedwater quality to downstream reverse osmosis systems.
Best results are achieved with municipally treated feedwaters and raw waters that contain relatively low concentrations of particulates and organic color. Upper raw water limits of turbidity and color for this product are 2.0 NTU and 10 units, respectively.
Performance:
RoQuest® 3000 provides an array of performance and application benefits:
- Capable of producing RO quality feedwater in direct filtration applications (i.e. multimedia and sand filters).
- Compatible with thinfilm and cellulose acetate RO membranes.
- Filter-aid properties resist solids breakthrough.
- Low dosage requirements.
- Compatible with Avista Technologies antiscalants Vitec 3000, 5000 & 7000.
- Effective over a wide pH range.
- No minimum alkalinity requirements.
- Internal biostat inhibits biological growth in the drum and feed tank.
Use Instructions:
If possible, inject RoQuest® 3000 at least 15 feet (5m) upstream of the multimedia filters. This distance allows proper mixing within the feedstream before introduction into the filter. 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® 3000 dosage is in the range of 0.5 to 4 ppm. For specific dosing calculations, refer to the Avista Dosing Guideline.
Significant overdosing of RoQuest® 3000 may cause degradation in the quality of the filtered water. If there are any questions, please contact Avista Technologies for specific dosing instructions.
Dilution:
Prior to injection into the feedstream, the RoQuest® 3000 can be diluted at a rate of 25:1 using dechlorinated water. This can improve product effectiveness but is not generally necessary.
