Cyclonic Separation Sand Filter River Water Treatment

cyclonic separation Sand FIlter River water treatment



A hydroclone is a device for separating a solid-liquid mixture during an industrial process by using a conical vortex and centrifugal force. Depending on the application, we may use a hydroclone in a system to provide primary stage filtration to remove larger particles before we pass the water to finer levels of the filtration process.
 
The hydroclone uses cyclonic separation which is a method of removing particulates from a water stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids.

 
PRODUCT ADVANTAGES
Conical shape accelerates the velocity of the water increasing centrifical forces and maximizing separation.
Easy to operate and maintain with no moving parts or screens.
No headloss build-up or clogging during separation.
Specially designed rubber cone/insert protects the neck from erosion and increases separation.
Large holding capacity of sedimention tank reduces flushing frequency.
Maximum anti-corrosion protection with durable and long-lasting coating materials.
 




Advantages of cyclone filtration
A high speed rotating water flow is established within a cylindrical or conical container called a cyclone. Air flows in a spiral pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger (denser) particles in the rotating stream have too much inertia to follow the tight curve of the stream and strike the outside wall, falling then to the bottom of the cyclone where they can be removed. In a conical system, as the rotating flow moves towards the narrow end of the cyclone the rotational radius of the stream is reduced, separating smaller and smaller particles. The cyclone geometry, together with flow rate, defines the cut point of the cyclone. This is the size of particle that will be removed from the stream with a 50% efficiency. Particles larger than the cut point will be removed with a greater efficiency, and smaller particles with a lower efficiency.

Working principle
Hydrocyclone sand separator is based on the principle of centrifugal sedimentation and density difference, At a certain pressure, the flow into the device, have a strong rotary motion, due to the different densities of sand and water, under the effect of centrifugal force, centripetal buoyancy, fluid drag force, so that the low density of the water rises, discharged from the overflow port, high density of sand from the bottom, so as to achieve the purpose of grit removal. Under certain terms and conditions, the higher water pressure, 
the higher the grit removal rate, it can also be fixed in parallel.




APPLICATIONS
For separation of sand and other solid matter from water
Protection of valves and irrigation systems from damage/abrasion caused by sand and other solid matter
Pre-filtering of water with high loads of sand, disc and screen filters

Installation Precautions
 
1. Hydrocyclone sand separator should be installed in the main pipe of water supply network and fixed on the 
base, we need to add a bypass between the inlet and outlet.
 
2. In order to ensure smooth water flow in front of the device should be installed intake and intake period equal 
diameter of straight pipe length equivalent to 10 to 15 times the diameter of the intake.
 
3. The equipment should be installed around the reserve has enough space for maintenance.
 
4.During normal operation, the need to open the inlet and outlet valves, close the drain valve and bypass valve.
 
5.depending on how much sand content of regular source of water decontamination platoon sand, open the
 drain valve at the sewage, water can flow out until the sewage process does not affect the normal use of water.
 
6.After sewage, close the drain valve.
 
7. If lack of sand discharge pressure, close the valve at the outlet.
