Grit Handling/Removal/Hauling

Envirodyne Systems OctoCell

The OctoCell grit removal system from Envirodyne Systems uses stacked trays to achieve a small footprint. Unique to their design is the inlet trough and tentacle arrangement above the trays, which means the flow path to each tray is the same size/length to better equalize pressure drops, meaning reduced headloss and greater grit removal efficiency. It allows for visual detection of any plugging and serves as a means of controlling flow to each individual tray. It has the ability to engage/disengage trays automatically based on flow variations. A “lollipop” configuration is also available for enhanced control of velocities and reduced organics accumulation. 717-763-0500; www.envirodynesystems.com

Fluidyne Hydro-Grit

The Fluidyne Hydro-Grit high-efficiency vortex grit-removal system is capable of removing 95% of all grit 75 micron and larger at all flow up to peak design flow. The grit separator can be supplied freestanding in stainless steel or fiberglass tankage, eliminating the need for concrete influent and effluent channels. Alternately, in cold weather climates or areas with limitations with existing hydraulic profiles, the unit can be submerged inside a concrete structure provided by others. It requires a minimal footprint and is designed to limit headloss. No internal moving parts eliminates maintenance inside the tank or structure. Large baffling and weirs abolish the need for a continuous source of flushing water for proper performance and to prevent plugging. It can be used at industrial and municipal wastewater treatment plants to remove fine grit and sand with pre-engineered models ranging from 0.5 up to 50 mgd. 319-266-9967; www.fluidynecorp.com
