About ENG Designs
About ENG Designs LLC
Founded in 2018, ENG Designs develops engineered water and wastewater mixing technologies focused on hydraulic efficiency, operational simplicity, and long-term performance.
The company was established to challenge conventional mechanical mixing approaches by applying core principles of fluid dynamics, buoyancy, and controlled air release. Rather than increasing mechanical complexity, ENG designs systems that transfer energy efficiently through predictable hydraulic circulation.
Our flagship product, the Hydra-Bubble™ large-bubble wastewater mixing system, delivers low-pressure, buoyancy-driven hydraulic mixing designed to maintain solids suspension and stable basin conditions in municipal and industrial treatment facilities. Every system is engineered for durability, scalability, and reduced lifecycle cost.
Brian Van Roy — Wellington, Florida Master’s in Engineering Specialization in Hydraulics and Pneumatics
Brian’s expertise centers on hydraulic system design, energy efficiency optimization, and simplifying mechanical infrastructure to reduce lifecycle cost and improve long-term reliability. His work focuses on applying fluid mechanics principles to create practical, durable solutions that eliminate unnecessary mechanical components while maintaining predictable performance in demanding wastewater environments.
He leads product development with an emphasis on controlled energy transfer, structural integrity, and real-world operational simplicity.
Charles Otis — Milwaukee, Wisconsin Master’s in Environmental Technology (Miljøteknikk)
Charles specializes in biological treatment processes and environmental system integration. His work bridges hydraulic mixing performance with biological process objectives, ensuring that circulation supports nutrient removal, solids suspension, and basin stability without disrupting treatment intent.
He focuses on aligning engineering design with process biology, delivering mixing solutions that enhance treatment efficiency through practical, science-based system development.
Technical Philosophy
ENG Designs operates at the intersection of hydraulic physics and practical wastewater engineering. Rather than increasing horsepower or mechanical torque, the company focuses on controlled energy transfer through buoyancy-driven displacement.
This approach prioritizes:
• Predictable basin-scale circulation
• Reduced submerged mechanical exposure
• Energy-efficient mixing intensity
• Simplified infrastructure integration
• Long-term operational stability
By engineering around fundamental fluid principles, ENG designs systems that are inherently scalable, adaptable, and resilient in demanding treatment environments.
This hydraulic-first approach is applied across our Hydra-Bubble™, Hydra-Fusion™, and Hydra-Dose™ systems.
ENG Designs serves municipal and industrial wastewater facilities throughout the United States with engineered large-bubble mixing and hydraulic circulation solutions.
What Makes ENG Designs Different
• Hydraulics-first system design
• Emphasis on energy efficiency and lifecycle cost reduction
• Integrated biological and hydraulic alignment
• Engineering-grade CAD documentation and system modeling
• Direct collaboration with consultants, operators, and municipalities
ENG does not position itself as a hardware vendor. The company functions as an engineering partner focused on delivering controlled hydraulic performance with measurable operational value.
Our Vision
Wastewater treatment facilities face increasing energy costs, regulatory demands, and infrastructure aging challenges. ENG Designs is committed to developing mixing technologies that simplify operation while enhancing process reliability.
The long-term vision is clear: redefine wastewater mixing by replacing unnecessary mechanical complexity with intelligent hydraulic design.
