Dear Sir or Madam:

A passive surface water intake screen is a submerged static filter without the need for any working components.
The passive HAIXING surface water intake screen acts as a filter to protect a pumping station against damage from floating debris but without any environmental i***ct.
HAIXING designs, manufactures, and markets the complete unit inclusive of the backwashing system.
HAIXING can provide complete assistance on site for installation and start-up.
DESIGN
A very low entrance velocity (0.1 m/s), a very high open area (up to 80 % open area) and a non-clogging surface are the main parameters in the design of a single or double cylinder intake screen.
Starting with the flow rate, the open area and the slot entrance velocity, we design the best arrangement whilst keeping in mind the screen diameter must be less than half of the available water depth.
When dealing with large flow rates, we propose multiple screen system (always an even number to avoid uneven distribution).
