Media Filtration System
Automatic Backwashing Water Treatment Shallow Sand Media Filter
Overview
The shallow medium filter uses natural sea sand as the filter
medium. Under a certain pressure, the water with high turbidity is
filtered through a certain thickness of granular or non-granular
natural sea sand, effectively intercepting and removing suspended
solids, Organic matter, colloidal particles, microorganisms,
chlorine, smell and some heavy metal ions, etc., and finally
achieve a high-efficiency filtration device that reduces water
turbidity and purifies water quality.
Working Princple
When the system is in the filtering state, the unfiltered water
passes through the upper water distributor, cooperates with the
spherical shell, and reaches the packing layer in the filter in a
state of nearly advection. When water flows through the packing
layer, impurities are trapped within the packing layer. The
collector at the bottom of the filter collects the filtered water
evenly and flows out. Advection filtration determines that the
filter can still achieve good filtration effect under high flow
rate.
As impurities continue to accumulate in the packing layer, the head
loss (ie differential pressure) will continue to increase. When the
pressure difference reaches a certain set limit or the filtration
time reaches the set value, the system will automatically switch to
the backwashing state to clean the packing layer and remove
accumulated impurities. For the system, regular backwashing is
required to remove Accumulated impurities are necessary.
When the system enters the backwash state, the on-off position of
the three-way valve is changed through PLC control (the inlet is
closed, the sewage port is opened), and the filtered water in other
filter tanks flows into the filter tank to be backwashed. The
packing layer of the filter unit backwashed by the system pressure
is washed up under the impact of the water flow, and the impurities
are discharged through the sewage outlet of the three-way valve.
