Wastewater Process Optimization
Hazen and Sawyer has extensive experience in the design, construction, startup and optimization of wastewater process improvements, with particular emphasis on designs to minimize operating cost and capital expenditures. We provide best-value solutions that will save you money.
Decades of designing new plants, upgrades to meet lower nutrient limits, plant expansions, facility re-ratings, process optimizations, and independent research have all shaped our approach to process modeling, design, and optimization. Our whole-plant approach recognizes the interconnectivity of all the elements of the wastewater treatment process, focusing on the most cost-effective and reliable means to achieve desired levels of treatment. We have worked with clients of all sizes and in all locations to construct projects that are on schedule, within budget, and are currently exceeding the required effluent nutrient standards.
We develop true whole-plant process models using industry standards such as BioWin or GPS-X® in combination with proprietary tools such as our 2Dc Computational Fluid Dynamics clarifier model and our Hazen Energy Efficiency Tool (HEET). Together, these tools provide the most complete understanding available of process alternatives and identify process optimizations that will bring the greatest return on investment.
We offer our clients both world-renown process modeling and unsurpassed technical knowledge, taking an operator’s perspective in developing process alternatives founded in realistic operability and sustainable maintenance.
Whether your average daily flow is less than 1 mgd or 300 mgd, whether you need to upgrade to secondary treatment or achieve nutrient removal at the limits of technology, you can trust Hazen and Sawyer to help solve your toughest water environment challenges.
