In-line Mixing for Water Treatment

Sharpe Mixershas been providing in-line mixers for a leading process equipment manufacturer for many years. It's a business relationship that has grown and prospered as a culmination of the technical knowledge and experience our partnership offers.

The mixing process is referred to as flash mixing. Due to the minute amounts of solutions added to the relatively large amount of raw water treated, flash mixing coagulants and other chemicals is necessary. Instant diffusion of the coagulant solution is required, or many particles will be missed, resulting in an overall higher turbidity or excessive use of coagulant. This is because rapid chemical reaction starts the instant alum or other coagulant is blended with raw water.

In this application, Sharpe mixers are mounted to a pipeline where they provide continuous, instantaneous blending of coagulant water prior to flocculation. This is done by (2) impellers mounted to the mixer shaft, pumping towards each other at high speed. Of course, other technology comes into play here as well!

How can our flash mixer arrangement help you? Contact us today to find out!
