Biological wastewater treatment plant DAVCO™

Overview Turnkey wastewater treatment solutions delivered in months rather than years. DAVCO™ field-erected treatment plants provide effective reduction of biochemical oxygen demand (BOD), total suspended solids (TSS), total nitrogen and phosphorus. For over 50 years, Evoqua’s DAVCO product and service teams have partnered with municipalities, developers and engineers to deliver turnkey projects with shortened concept-to-completion timelines. DAVCO field-erected plants offer flexible application options for footprint, flow rates, treatment levels and site constraints. Capacities range from 0.1 to 5.0 million gallons per day (mgd) and are available in multiple configurations, including activated sludge, sequencing batch reactors (SBR) and oxidation ditch. Construction material options include carbon steel, galvanized steel, stainless steel and concrete, or any combination of these materials. Shorter delivery schedules can reduce overall capital, maintenance and operating costs. Full turnkey, retrofit and upgrade solutions are available.

Key benefits

• Quick installation — permanent field-erected biological systems are pre-assembled and then erected on site
• Smaller footprint with less yard piping, electrical conduit and maintenance compared to site-built concrete systems
• Wide range of biological process options and special configurations such as the unique dual-path design
• Suitable for colder climates when partially or fully buried to protect from freeze damage

Features

• Rehab or retrofit of existing equipment regardless of original manufacturer
• Single-source responsibility for delivery and commissioning
• Over 50 years of operational and process expertise
• Equipment engineering and quality manufacturing
• Short on-site completion timeline
