System Overview
The Amiad DVF High-Efficiency Water Filter is designed to remove suspended particulate from water down to 1
micron nominal in size at an efficiency of 90% (by mass) at the filter’s designated flow rate.
The unit operates at the 5-7 bar (refer to technical data table on pp.8) working pressure. It operates fully
automatically with its automatic backwash system. The backwash control is based on pressure differential and/or
timer control. The system’s backwash water flow for a single regeneration is specified in the Data Sheet.
This filter system consists of an SST 304 filter vessel rated according to BS EN13445.
The filter vessel comes complete with an internal stainless-steel support plate, into which a set of non-metallic
diffusers for media retention and the backwash distribution across the filter area are fixed.
This filter unit is supplied with multi-level graded glass.
The backwash period is adjustable depending on the nature of the contamination being removed.
Filter Configuration
The DVF is a patented filter system for water, which can remove particulate down to 1 micron nominal in size.
Each unit has a total of
four valve connections
– namely:
Process Inlet Valve V1 - This is the filter’s inlet connection for the dirty process water supply. The connection is located in
the upper part of the vessel with the entry point on the top lid. The water passes through the internal pipe equipped with
a Dual Vortex Generator incorporated into the internal inlet pipework.
Process Outlet Valve V2 - This is the filter’s outlet connection for the filtered (clean) water. The connection is
connected to the process system. We recommend that you install a flow control valve (full bore manual gate
valve) at this location to correctly set the flow for your process during commissioning. The valve can be supplied at
extra cost, if required.
