Super Subsurface DAF Unit – Patent Technology Dissolved Air Flotation
The Super Subsurface Dissolved Air Flotation (DAF) system was successfully developed in October 2003 and received advanced technology patent protection in 2007, with the patent number: ZL2007 2 0155718.3. This innovative technology has earned recognition as a product of technological innovation and was strongly recommended by SEPA (State Environmental Protection Administration) in 2008.
The Super Subsurface DAF is a leading unit in the water treatment industry, widely used in various sectors, especially in the pulp and paper industry. It achieves nearly 100% removal of suspended solids (SS) and over 85% removal of chemical oxygen demand (COD).
**Application Fields:**
- Primary and secondary treatment of industrial wastewater
- Liquid containing suspended solids
- Replacement for primary desilters in chemical pulping
- Treatment of waste paper in pulp and paper mills
**Features and Advantages:**
- Highest SS trapping efficiency (nearly 100%)
- High sludge concentration (up to 12%)
- Can handle large fluctuations in wastewater flow
- Low energy and chemical consumption
- Modular components allow for easy expansion and increased production
**Description:**
The KS Air Flotation Clarifier is a specially designed system that integrates the separation of suspended particles and dissolved air flotation. Wastewater is pumped into the feed chamber, where it is mixed with pressurized recycled water through a special device. The dissolved air water is released at the bottom of the flotation tank, creating microbubbles that attach to suspended particles, causing them to float to the surface for removal.
**Technical Specifications:**
