Portugal + Sand Filter + Solid-liquid Separation

Product: Sand Filter

Country: Portugal

Application: Solid-liquid Separation

Sand filter is a commonly used water treatment equipment, mainly used to filter and remove impurities such as suspended matter, silt, bacteria and organic matter in water. The following is a detailed introduction about it.

1. Filtration process

When water passes through the sand filter, suspended matter, impurities, etc. in the water will be intercepted by the sand filter layer. Because the particles of the sand filter layer are of different sizes, the particles in the upper layer are larger, which can first intercept larger suspended matter and silt. The particles in the lower layer are smaller, which can further intercept smaller particles, bacteria and organic matter, etc., so as to purify the water.

2. Structural composition

Filter unit: It is the core component of the sand filter, which is composed of multiple layers of sand layers. The particle diameter of each layer of sand layer gradually decreases, forming a particle gradient from top to bottom, so as to achieve effective filtration of different sizes of impurities.

Support unit: It plays the role of support and diversion, ensuring that the water flow is evenly distributed in the sand filter layer, reducing the water flow resistance, and ensuring the stability of the filtration effect.

Hydraulic and pneumatic cleaning system: It is used to clean the sand filter after filtering for a period of time to restore its filtration performance. Hydraulic cleaning is to flush the sand filter layer with reverse water flow. Pneumatic cleaning uses air to stir the sand filter layer to loosen the dirt and discharge it with the water flow.

Supporting equipment: including inlet and outlet pipes, valves, instruments, etc., used to control the direction, flow and pressure of the water flow, as well as monitor and adjust the operating status of the sand filter.

Sand filters play an important role in many fields due to their good filtering effect, wide adaptability and stable operating performance. It is an efficient and practical water treatment equipment.
