Function:
Use the filter to directly intercept impurities in the water to
purify the water and protect other equipment in the system from
working properly.
Application
Commercial - Golf course and sporting field irrigation systems.
Industrial - Pre-preteatment of UF/RO and waste water recycling.
Irrigation - Primary filtration for the prevention of blockages in
irrigation system
HVAC- cooling tower side filtration and full system
Metal Processing Plants - Filtration for water cooling and spray
nozzles.
Mining - Cleaning of process and waste water.
Product structure
Product principle
The water flows through the screen and the particles are retained
on the inside of the screen of the filter element.
The filtered water then flows out through the outlet.
When the particles accumulated to a certain number and the pressure
differential increases to the pre-determined level,
the flushing cycle starts.
It include two steps: First, the automatic drain valve opens on the
drainage outlet.
Then, electronic motor drives the cleaning brushes which are inside
the screen, the solids are expelled through the drain valve.
Filters continue to supply filtered water even during the flushing
cycle.The whole working system is controlled by a smart box which
has several control modes: pressure differential, time, manual and
PLC.
