UniMix: A Versatile Tool for Enhanced Environmental & Water Treatment

In the realm of environmental and water treatment, efficient flocculation is crucial for removing suspended solids and achieving high-quality effluent. The UniMix, a cutting-edge technology developed by Walker Process Equipment, offers a unique and effective approach to this critical process.

UniMix: What is it?

The UniMix is a specialized flocculation unit designed for optimal particle aggregation and settling. It leverages a combination of horizontal and vertical mixing to achieve superior flocculation compared to traditional methods. This hybrid approach allows for a wider range of application across various water treatment scenarios, ensuring effective removal of contaminants regardless of the water source.

Vertical Flocculation: A Deep Dive

The vertical aspect of the UniMix system provides efficient mixing within the flocculation tank. By utilizing a specially designed impeller, the system creates a strong, upward flow, encouraging particle suspension and facilitating uniform distribution of flocculants throughout the tank. This ensures consistent contact between the flocculants and the suspended particles, promoting optimal aggregation and settling.

Horizontal Flocculation: The Key to Success

The horizontal component of the UniMix system introduces a gentle, horizontal flow, creating a gentle sweeping motion within the tank. This horizontal flow helps to align and consolidate the flocculated particles into larger aggregates, further enhancing settling efficiency. The gentle nature of this flow also minimizes the potential for shear forces that could break down the formed flocs.
