Dissolved air flotation handles a wide range of wastewater applications reliably. But engineers who work with fine suspended solids — particularly clays, fine silts, and other small-diameter particles — know that standard DAF can plateau before hitting the removal efficiency the application demands. More coagulant, more polymer, slower flow rates — and the effluent still …
We talk to a lot of municipal operators who are facing the same situation: the DAF that’s been running reliably since the early 1990s is at end of life, and now there are more options on the market than there used to be. Some of those options promise smaller footprints, lower horsepower, and higher efficiency …

In our last post, we introduced aphron microbubbles — what they are and why their stability and electrostatic properties make them effective for flotation. This post covers how Tenco Hydro has integrated a third-party aphron generator into our DAF platform to create a hybrid system we call DAF+. Tenco Hydro’s strength is system engineering and …

If you’ve been following developments in flotation technology, you’ve probably started hearing more about aphron microbubbles. This post explains what they are, where the science comes from, and why they represent a meaningful advancement in how flotation systems remove solids from water. The Physics of Standard Flotation In a conventional dissolved air flotation (DAF) system, …

🛢️ What is a DAF Pressure Tank? A DAF pressure tank (saturation vessel) is used to dissolve air into a recycled stream of water under pressure. This air-saturated water is then released into the DAF unit, where microbubbles help float suspended solids. ⚖️ Vertical vs. Horizontal Pressure Tank: Comparison Feature Vertical Pressure Tank Horizontal Pressure …
🔬A Deep Dive DAF Comparison: Pressurization Technologies Krofta Tube vs. Whitewater Skid vs. Hellbender Pump When it comes to Dissolved Air Flotation (DAF) systems, the pressurization method is the backbone of flotation performance. It controls bubble formation, solids attachment, and removal efficiency — especially in high-strength industrial wastewater like that from metal finishing, food processing, …
Metal finishing plants face some of the most demanding wastewater treatment challenges in industry. Between heavy metals, oils, surfactants, and shifting pH, Dissolved Air Flotation (DAF) is often the go-to technology to polish wastewater before discharge or reuse. But not all DAF systems are created equal — and the pressurization method used to generate dissolved …

Lift stations are critical components in wastewater and stormwater infrastructure, responsible for moving water or sewage from lower to higher elevations when gravity flow isn’t sufficient. Whether you’re dealing with an aging system, unexpected failure, or planning a major retrofit, having a clear plan is essential. Here’s a practical guide outlining key considerations and modern …

The Nuances of Using DAF for Thickening: Key Considerations for Optimized Performance Dissolved Air Flotation (DAF) systems are commonly used for separating suspended solids, oils, and grease from wastewater. However, when applied to sludge thickening, the dynamics of the process shift significantly. Thickening sludge using a DAF system requires careful adjustments to operational parameters, system …
API oil water separators are a critical part of wastewater treatment systems, designed to remove oil and hydrocarbons from water before further processing. Used extensively in industries like petrochemical, manufacturing, and automotive, API separators require regular maintenance to ensure efficiency and compliance with environmental standards. In this blog post, we’ll outline the key components of …
