Dissolved Air Floatation(DAF) Clarifier for Sewage Treatment

Efficient dissolved air floatation clarifier is a shallow pool precipitation theory to design an efficient modular clarifier. Regional settings in the settlement of many intensive inclined tube, inclined plate, suspended in water by precipitation of impurities in the inclined plate or inclined tube, the flow of water rise along the inclined plate or inclined tube, isolated from the sludge under gravity along the inclined plate (tube) downward slide the bottom, and then concentrated discharge. This pond can improve the efficiency of precipitation 50 ~ 60% can increase the processing capacity of 3 to 5 times in the same area. Sedimentation of the design flow according to the raw wastewater test data are generally required to use coagulant dosing. Efficient inclined tube to clarify the water purification method is suspended in the sludge layer above the installed angle of 60 degrees inclined tube formation, will be in raw water suspended solids, the solids formed by adding coagulant flocs of alum, accumulation of side surface area of the inclined tube into a thin mud layer, relying on gravity to slip back into the sludge suspension layer, and then sink into the mud bucket. Discharged into the sludge pool to be dealt with separately or comprehensive utilization of pipe from sludge. Supernatant gradually increased to the set of pipes discharge can be discharged directly or reuse.

Features

1. Simple structure, no wearing parts, durable, and reduced maintenance.
2, stable, easy to operate.
3, power, energy conservation.
4, covering the province, less investment, quickly launched, high efficiency.
5, the short residence time, the effect of high precipitation, high efficiency, low aeration intensity, without sludge return.

Usage

1. Electroplating wastewater containing a variety of metal ions in the mixed wastewater, chromium, copper, iron, zinc, nickel removal in more than 90%, general electroplating wastewater after treatment are available to meet emission standards.

2, coal, mineral processing waste can turbidity in the 500-1500 mg / lift to 5 mg / l.

3, such as dyeing, bleaching and dyeing wastewater color removal 70-90%, 50-70% COD removal.

4, a large number of tanning, food industry wastewater organic matter removal, COD removal of 50-80%, more than 90% of impurities in solids removal.

5, 60-70% of the COD removal efficiency of chemical wastewater color removal by 60-90%, suspended solids up to emission standards.
