Municipal Water & Drinking Water
Pre-treatment of municipal wastewater and drinkwater production
Kroft DAF solutions for drinking water and municipal wastewater treatment
Krofta Dissolved Air Flotation (DAF) systems have become a vital technology for municipal water and wastewater treatment applications. Renowned for their versatility and efficiency, these systems address a wide range of treatment challenges, from drinking water production to municipal wastewater and resort-scale solutions.
By leveraging advanced flotation and filtration technologies, Krofta DAF units offer cost-effective, reliable, and highly customizable solutions to meet the needs of municipalities and large commercial operations.
Drinking Water Applications
Krofta DAF units and Krofta Sandfloat technology have proven highly effective in municipal drinking water production. Whether a city is treating surface water or another raw water source, these systems deliver reliable results in reducing total suspended solids (TSS) and removing specific metals, such as iron, prior to final filtration.
- DAF as a Roughing Clarifier:
DAF systems are commonly employed as a roughing clarifier to reduce TSS before water reaches downstream filtration processes. By effectively removing particulate matter and some dissolved metals early on, the DAF enhances the overall treatment train, improves filter run times, and reduces chemical usage. - Krofta Sandfloat Technology:
For municipalities seeking a combined solution, the Krofta Sandfloat—a hybrid DAF system with a built-in dual-media filter—offers exceptional water quality. By reducing and minimizing particles and metals in a single system, Krofta Sandfloat units simplify treatment processes, making them an ideal choice for cities looking for efficient, compact, and high-performance solutions
Municipal Wastewater Treatment
Municipal wastewater treatment plants—commonly referred to as Publicly Owned Treatment Works (POTWs) or Municipal Wastewater Treatment Plants (MWTPs) face unique challenges in handling diverse influent streams. Krofta DAF systems have been successfully applied in both pretreatment and thickening steps, delivering significant performance improvements.
- Industrial Pretreatment at Smaller POTWs:
For smaller POTWs or WTPs that receive high-strength wastewater from large industrial dischargers (such as dairies or food packaging plants), Krofta DAFs have been installed at the headworks as a cost-effective pretreatment step. By reducing oil and grease (O&G) and high solids before the main municipal treatment process, the DAF protects the POTW, enhances efficiency, and lowers operational costs for both the industrial contributor and the treatment plant. - Waste Activated Sludge (WAS) Thickening:
Krofta DAF systems excel in thickening Waste Activated Sludge (WAS) from activated sludge processes. Comparative trials often show that Krofta DAF units outperform other thickening devices, delivering superior solids capture and higher concentration, ultimately reducing sludge handling and disposal costs.
Wastewater Treatment for Resorts and Hotels
Large resorts and hotels often operate as mini-municipalities, managing their own water and wastewater treatment on-site. Krofta DAF systems have been widely adopted in these settings due to their compact design, modularity, and effectiveness in handling a variety of water qualities.
- Cost-Effective Treatment for Diverse Streams:
Resorts and hotels frequently need to treat raw water, gray water, and combined wastewaters. Krofta DAF units, coupled with biological treatment systems, provide a reliable and cost-efficient solution to meet discharge standards and ensure water reuse opportunities. - Flexible Installation Options:
These systems are available as skid-mounted units that can be field-assembled, or as complete containerized packages ready for rapid installation and start-up. This flexibility makes Krofta DAF an ideal choice for remote locations or facilities with limited infrastructure.
