Water treatment solutions in water supply sector

Rapid filtration equipment (porous brock)

Outline

Rapid filtration equipment is a core component of supply water treatment. At the same time, it is also important as a sophisticated treatment system for wastewater treatment such as those for environment preservation and water reuse.

METAWATER has a wealth of experience in the area of rapid filtration equipment including the following:

  1. Fixed-bed downward flow filtration
  2. Fixed-bed upward flow filtration
  3. Movable-bed upward flow filtration

We will propose an optimal system using porous blocks, etc.

Characteristics

1. Fixed-bed downward flow filtration

In this treatment method, the raw water coming from the top of the filtration layer flows down to the bottom of the filtration layer by gravity. During this process, SS is captured by filtration media.

2. Fixed-bed upward flow filtration

In this treatment method, an increased volume of SS can be captured by making the raw water flow in from the lower section of the filtration tank where coarse filtration media are accumulated. In this approach, filtration is carried out to the upward flow.

3. Movable-bed upward flow filtration

While it belongs to an upward flow type, the section for filtration process and the section for cleansing process are separated in a single-layer type of filtration layer in this method. Based on this structure, it is possible to continue filtration while cleansing the filtration media simultaneously.

Various types are available including the single type of steel material as well as the multi type to be integrated in the reinforced concrete tank.
