Hospital Wastewater Electrocoagulation Dissolved Air Flotation Equipment

Product Description

Dissolved Air Flotation Systems

Dissolved Air Flotation (DAF) has been known as one of the most effective and robust ways to remove suspended solids (TSS), biochemical oxygen demand (BOD₅), fats, oils, and grease (FOG), phosphorus (P) or nutrients from industrial wastewaters. In response to variations in industrial activity, variations in wastewater and water streams, and the ever-demanding customer requirements, EVU Industries has engineered one of the most intelligent and reliable Dissolved Air Flotation systems available.
 

 

 

When selecting a DAF system for your wastewater treatment plant or resource recovery installation, customers typically choose the DAF supplier and equipment based on their industrial experience, quality, performance guarantees, and reliability. As a result, EVU has provided more than 3000 Dissolved Air Flotation systems worldwide in various industries, including; food and beverage production, dairy processing, meat processing, agricultural, oil and gas, and municipal markets, to name a few.

 

What is Dissolved Air Flotation, and how does Dissolved Air Flotation work?

 

Dissolved Air Flotation is based on a physical/chemical process, where air is injected into the water stream and with chemical assistance causes the particles/flocks to float to the surface. This floating sludge layer is then automatically and continuously removed by a scraper mechanism. The DAF system will produce a treated effluent virtually free of TSS, FOG, and removes a large portion of the BOD.
 

 

What are the EVU Industries Intelligent Dissolved Air Flotation benefits and features?

• Maximum TSS, FOG, and BOD removal efficiency and reduced energy consumption with the EVU patented i-AERATION system.
• Reduced installation time as EVU DAF units are shipped as prefabricated units with onboard mounted equipment. Additionally, compact DAF units can be installed in containers or on a box frame or skid.
• Suitable for several polluted water types and applications based on the EVU Dissolved Air Flotation material execution.
• Operational flexibility and reduced sludge disposal with Nijhuis smart level control and sludge scraper system.
• Reduced footprint with EVU Plate Pack Technology.
• High solids loading with EVU Open Flotation Technology.

Why Dissolved Air Flotation?

The Dissolved Air Flotation system has proven very effective in industrial wastewater pretreatment and has been used in various water, wastewater, and desalination applications. To maximize the removal of suspended solids and colloidal particles and substances, a flocculator with chemical dosing can be added in front of the DAF. This ensures the polluted water is chemically pretreated before entering the DAF unit, thereby providing maximum removal rates (TSS and FOG in excess of 95% is common).
Depending on the application and the client's requirements, a DAF system can be fabricated in concrete construction or, for very large flows, in stainless steel. The most common DAF treatment applications include:

• Pretreatment for TSS and FOG removal from Industrial wastewater
• Fats, oils, and grease resource recovery
• Drinking water intake solids removal
• Water treatment pre-treatment to remove solids and algae blooms
• Wastewater biological treatment as activated or anaerobic sludge flotation
• Wastewater tertiary treatment to remove phosphorus and nutrients
• Pretreatment for Desalination systems
• Process water production
