Selecting Wastewater Mixers for Wastewater Treatment – Part 1 Wastewater Mixers for Optimal Chemical Preparation Chemical preparation in wastewater and water treatment directly impacts many downstream processes. Let’s take a look at several common chemicals used and some key factors that influence their preparation and the selection of wastewater mixers. Lime Slurry Preparation When preparing lime slurries for controlling pH, uniformity is critical. Why? Because lime solids must reach/stay in suspension if they are to serve their purpose in downstream processes. For this reason, it’s essential that wastewater and water treatment facilities have lime slurry mixers that can efficiently and effectively make up/maintain uniform slurries. In order to successfully suspend/re-suspend solids, a mixer needs to create a flow pattern that involves the entire

Selecting A Waste Water Mixer for Wastewater Treatment – Part 2 Waste Water Mixers for Optimal Flash Mixing & Flocculation In part 1 of this series on wastewater and water treatment mixers, we discussed how to select a waste water mixer for chemical preparation. In this post, we’ll show you how to select a Waste Water Mixer for flash mixing and flocculation. Done in a Flash? Aggressive Agitation + Speed for Flash Mixing Flash mixing is used to evenly distribute coagulating chemicals in water, allowing micro-flocs to form. As the precursor to flocculation, flash mixing increases the efficiency of flocculation and reduces chemical wastage. Because the components need to be quickly and evenly dispersed, this process is all about brute
