The working principle of the fiber nano (flame retardant) filter: It is generally composed of a dosing device, a raw water booster device, a filter system pipeline, a tank, an air recoil device, a backwash water pump device, and an electronic control system. When using tap water, flocculants should be added to the raw water. The raw water enters the filter through the filter system pipeline, and the flocculant is stirred by the water pump impeller (or static mixer) and evenly mixed with the raw water. The fine solid particle suspension in the raw water quickly generates flocs larger than 5μm, which are intercepted by the filter material in the filter, and the clean water is discharged through the outlet pipe at the bottom of the filter and flows to the next process.

Filter material is a new type of filter material, its most significant feature is asymmetric structure and fractal structure. It not only has the advantages of high filtration accuracy and large dirt interception capacity of the fiber filter material but also has the advantages of good backwashing effect of the granular filter material and low water consumption. The void ratio distribution of the filter bed formed by this filter material is close to that of the ideal filter material. structure.

Equipment use conditions: normal use pressure <0.4MPa, normal use temperature 5~50℃, the filter medium is raw water, the turbidity before filtration is ≤10mg/L, the use environment is a place with relative humidity not more than 80%, ventilation and no acid, alkali or other harmful gases.

Economic benefits

Water consumption calculation. The fiber nano filter has a large water production cycle and low backwash water consumption, which reduces water consumption and reduces sewage discharge.

Process effect. The fiber nano filter not only improves the quality of the effluent, the turbidity of the effluent is stable and less than 1mg/L but also reduces the burden on the reverse osmosis or ion exchanger and reduces the pollution to the resin.

It solves the problem of frequent replacement of filter materials, saves maintenance costs, and reduces the labor intensity of operators.

It occupies a small area, reserves space for the later expansion of the plant, and saves civil engineering costs.

The fiber nano filter also adds flame retardant components to ensure that the risk of dust in the air is reduced during the filtration process. It has the characteristics of fast filtration speed, high precision, large interception capacity, easy backwashing, low water consumption, low operating costs, and a small footprint, which fully meets the water quality requirements of the subsequent water treatment system.
