DAF-Roll Flow DAF

We have standarized DAF products ,have 5 types in total.The left picture is our RF-DAF series.It has thoese main features: 1.Perfect solution for large flowrate project 2.Design capacity from 200m3/h to 1200m3/h 3.Air dissolved water are distributed to the whole tank equally with patent design 4.Design hydraulic loading rate:15-25m3/m2/h

Introduction

Brief Introduction

Dissolved Air Flotation (DAF) has been known and applied widly as one of the most effective and economic ways to remove suspended solids (SS),fats, oils and grease (FOG), phosphorus (P) from industrial wastewaters by the generation of micro bubbles.
Jorsun DAF is an innovation combined with traditional dissolved air flotation design theory and modern technology after years of research and application.DAF is based on a physical / chemical process.Wastewater is dosed with treatment chemicals upstream of the DAF inlet to form flocs.

When those flocs enter to the DAF chamber,massive of microbubbles attach to the flocs, and bring them floating to the top.The floating solids are harvested by DAF’s top skimmer. After the separation process, clean effluent will be collected and discharged.
The generation of micro bubbles is through the air saturation vessel and air diffuser plates.A portion of the DAF effluent is recycled to the air saturation vessel to mix with air by venturi jet under high pressure,and form air dissovled water(white water) .When the air dissoveld water flow to the air diffuser plates, the sharp reduction of pressure will make the microbubbles release from the air dissolved water,and form massive microbbubles.

High efficient roll flow DAF is a newly designed DAF equipment with high hydraulic load and large capacity.Our engineers carry out the comprehensive design based on flow state,flow speed, air dissolved water distribution density etc, and also utlize the FLUENT SYSTEM for calculation .Roll flow DAF subverts the traditional DAF design concept and is a revolutionary innovation for DAF technology .

Applied Industry

High Efficient Roll flow DAF is as a result of JORSUN team’s over 10 years’ cotinuous and study.

It’s a perfect solution for large flowrate project with not high SS (200-1200m3/h).

 

It’s officially launched in 2020 and then displayed in IE EXPO and AQUATECH CHINA in Shanghai in the same year.

Up to now,the high efficient roll flow DAF are successfully operated for WWTP upgrade, water purification of watertreatment plant,river ,and effluent after secondary clarifier etc.
