HYDRODYNE

 Hydro-Dyne Engineering’s fine screening systems combine cutting-edge design and proven reliability to protect sensitive water and wastewater processes by capturing particles as small as 0.5 mm, maintaining ultra-tight 0.5 mm seal tolerances for life, and eliminating submerged sprockets or bearings to prevent ragging. Engineered to minimize headloss, simplify maintenance and ensure dependable screenings discharge, these stainless-steel screens handle everything from sticks, leaves and algae in surface water to rags, wipes and hard plastics in the toughest wastewater environments. 

 Hydro-Dyne Engineering’s coarse screening systems are built to withstand the harshest water and wastewater environments—tackling everything from drainage canal trash to storm-sewer debris with grid openings up to 300 mm and reinforced structural supports for decades of trouble-free operation. Backed by over 40 years of design expertise, our stainless-steel coarse screens feature rugged grid, track and drive assemblies that minimize maintenance and repair costs, while customizable support options deliver unlimited resistance to deflection even under high headloss.  

 Hydro-Dyne Engineering’s turnkey screenings handling systems are engineered to seamlessly integrate with your fine and coarse screens, providing full-service acceptance, washing, dewatering, compaction and conveyance of collected solids.  By efficiently separating and reducing the volume of inorganic debris while recovering valuable organics for return to the treatment process, our equipment lets you specify finer screen openings and maximize capture without increasing disposal costs.  Built to the highest quality standards and custom-matched to your plant’s screening configurations, these robust systems ensure reliable, low-maintenance operation and optimal solids management across any water or wastewater application. 

 Hydro-Dyne’s Sand Shark Grit Removal Equipment delivers a single-source, turnkey solution for highly efficient grit capture at variable flow rates—removing over 95% of 300 µm particles with less than 0.25″ headloss—while minimizing energy and maintenance costs and retrofitting easily into sloped or flat-floor chambers with rugged all-stainless-steel construction. The vortex-style Sand Shark Grit Trap operates continuously on flows up to 70 mgd (3,000 L/s) with rotating impellers, 270° or 360° chamber designs, the Sand Shark Grit Classifier then elevates, dewaters, and discharges dry grit directly into a receptacle with bearings fully shielded from abrasion; and the wear-line-protected Sand Shark Hydro-Cyclone—mounted above the classifier inlet—provides no-moving-parts grit separation for long service life. 

 Hydro-Dyne’s Hammerhead On-site Screen Sizing brings a new era of data-driven headworks design by testing a plant’s actual influent characteristics—flow variations, particle sizes and blinding tendencies—using adjustable intake piping, non-contact flow meters, a wireless PLC interface and modular screening assemblies. Rather than relying solely on peak flow and opening size, Hammerhead quantifies screenings capture ratio (SCR), blinding capacity and solids stratification under real‐world conditions to prescribe the optimal screen type, opening, speed and dual-stage configurations. The result is more accurate hydraulic predictions, extended downstream equipment life, reduced capital and maintenance costs, minimized headworks flooding risk and overall improved treatment performance.
