DIRECTIONS FOR USE:
ENVKEM 9465 may be fed into the vortex of the stirred tank. Eductor may be used for efficient dispersion of polymer. Paddle stirrers operating at 30 to 60 rpm is recommended for dissolution. Use filtered water, free from suspended solids to prepare stock solution of 0.2 to 0.5% of concentration. Prepare feed solution by diluting stock solution about ten times directly or on-line diluting. Water may be heated to 50˚C to accelerate the dissolution. Higher temperatures are not recommended ENVKEM 98160 dosage for clarification is normally between 10 to 40ppm despending on suspended solids.
