FRP Multimedia Filter for Sea Water

FRP multimedia filter is a kind of FRP pressure vessel and also an important water treatment equipment. It mainly uses an aerobic treatment system to filter suspended matter, sewage, silt and other impurities in the water, reduce the turbidity of the water, and achieve the purpose of clarifying the water quality. The filter has the advantages of low cost, high operating efficiency, small footprint and long service life. Due to the excellent performance of its internal structure, efficient cleaning ability and long service life, it is favored by the majority of users and widely used in the field of water treatment.

Product details

Introduction:

The FRP multimedia filter is used to remove suspended solids and turbidity. It uses a variety of filter media for filtering operations, which can effectively remove impurities and particles in the water and purify the water quality. It is a new type of water treatment equipment. It is widely used in the water treatment industry due to its fast filtration speed, stable operation, energy saving, and reduced operating costs.

Features

1. The FRP multimedia filter uses a variety of media for filtration, which has better filtration effect and can effectively remove impurities and particles in the water.

2. The FRP filter has the characteristics of corrosion resistance, durability, lightness, etc. It is easy to install and suitable for various environments and water conditions.

3. The backwash system can automatically clean the filter medium to ensure the filtration effect.

4. The multimedia filter has a fast filtration speed, stable operation, energy saving, low maintenance cost, and reduced operating cost.

Operation precautions

1.Turbidity of water entering the bed.

If the turbidity of water entering the bed is high, it will bring too many impurities to the filter layer. These impurities are trapped in the filter layer and block the gap between the filter tanks, hindering the adsorption effect. If it runs for a long time, the filter medium will age and fail. Therefore, it is best to control the turbidity of water entering the filter below 5 mg/L to ensure its stable operation.

2.Backwash cycle.

The length of the backwash cycle is the main factor affecting the effect of FRP multimedia filter. If the backwash cycle is too short, the backwash water will be wasted; if the backwash cycle is too long, the adsorption effect of the filter medium will be affected.

Generally speaking, when the turbidity of water entering the bed is below 5 mg/L, it should be backwashed once every 4 to 5 days.

3.Backwash intensity.

During the backwashing of the filter, the expansion rate of the filter layer has a greater impact on whether the filter layer is thoroughly flushed. If the expansion of the filter layer is too small, the filter medium in the lower layer cannot be suspended and its surface is not cleaned; when the expansion is too large, it is easy to leak. During operation, the expansion rate is generally controlled to be 40%~50. Backwash intensity is 13~15L (m2·s)

4.Backwash time.

Generally, when the filter layer expansion rate is 40%~50% and the backwash intensity is 13~15L (m2·s), the backwash time of the filter is 8~10min.
