Header Lateral System Of Biological Aerated Filter

At present, the conventional BAF adopts the water filter nozzles as the water header lateral system. This method has various disadvantages in practical use, mainly including:

• The water header lateral system device of the water filter nozzles is often blocked, and bacteria and microorganisms are bred during long-term operation, which narrows or even blocks the water outlet hole of the water filter nozzles.
• The water yield of a single water filter nozzles is too small. During BAF backwashing, the passing water and gas volume are about 5 times that of normal. As a result, the BAF tank is full of water filter nozzles, which poses a potential safety hazard to the strength of the filter plate. It brings great inconvenience to installation and maintenance.

BLU-BSQ-H-05 Series BAF Pool Water Distributor Structure

• Biological aerated filter header lateral system, including water header lateral screen pipe, main pipe, branch pipe blind plug, main pipe blind plug, and lower air inlet.
• One end of the main pipe is provided with a main pipe blind plug, and the other end is an opening.
• A water distribution branch lateral screen pipe is fixed on the sidewall of the main pipe near the blind end of the main pipe.
• The sidewall of the water distribution branch lateral screen pipe is provided with a uniform wedge wire screen gap, and the end of the water distribution branch pipe is provided with a branch pipe blind plug.
• The main pipe is close to the lower air inlet at the open end.
• There are four water distribution branch pipes, which are fixed on the main pipe in a crossway.
• The BLU-BSQ-H-05new structure is reasonably designed to effectively prevent blocking, and back cleaning will not have a strong impact on the filter plate. It can be used stably for a long time.
