## Overview

 

 

 

For smaller trickling filters (2 to 4 metre diameter), Veolia Water Technologies can offer Cascade MiniFLO.

**Features**

- Cascade Distribution systems are individually designed and sized specific to plant and process requirements and site conditions.
- Single- or multi-stage distributor body permits operation at high turn-down flow ratios at both high and low flow conditions.
- Distribution hole sizing and spreading is computer-modelled specifically to ensure even liquid distribution over the total media surface.
- Distributor internal flow design eliminates the requirement for liquid seals. Instead, the Cascade unit utilises sealed, self-aligned heavy-duty bearings, located at the top of the distributor body to eliminate wastewater contact and provide easy access for maintenance and replacement. Bearing life is typically 100,000 operational hours.
- The distributor body, arms and rigging are available in Stainless Steel, GMS and specialist material finishes.

**Cascade MiniFLO**  
Cascade MiniFLO utilise all the features of CASCADE, but are specifically designed for very small trickling filters, typically between 2 and 4 metre diameters. The units are mounted from 2 beams across the top of the trickling filter containment vessel, with easily-accessible bearing assembly and optional motor-drive unit. The distributors are available in 304 or 316 Stainless Steel, GMS or plastic and can be supplied in single- or multi-stage configurations thereby enabling them to accommodate a wide flow range.
