RoQuest® 6000

RoQuest 6000 contains a mixture of organic coagulants and iron (III) ions and is designed as a coagulant and flocculant in clarifiers where flocculants are used. This product enhances filtration performance by reducing turbidity and colour. The water produced has a feed water quality that is more acceptable for downstream reverse osmosis systems.

Application:
Dose RoQuest®6000 at least 5m upstream of a multi-media filter. Do not use static mixers upstream of the filters, as the shearing caused by these devices will degrade the polymers contained in this solution.

Dosage:
Usually the dosage is between 5 and 35 ppm. Approximately 0.25 ppm alkalinity (calcium carbonate) is required per ppm RoQuest 6000. After addition of the coagulant, at least 25 ppm of residual alkalinity is required. A strong overdose of RoQuest 6000 may cause a deterioration in the quality of the filtered water. If you have any questions, please contact Avista Technologies for specific dosage instructions.

Dilution:
RoQuest 6000 should be added undiluted if possible. If dilution is necessary, you should never dilute more than 4: 1 with RO permeate or demineralised water.

Packaging / storage:
RoQuest 6000 is available in 23 kg canister, 230 kg drum  and 1100 kg IBC container. The product should be protected from frost during storage.
