1. Application area
The pre-filter Maxi Plus is installed underground and cleans the
inflow water before it enters the rainwater container. It has no
height offset.
The pre-filter Maxi plus is laid out according to DWA M 153. The
technical equipment of the filter is designed for a maximum load
such as courtyard surfaces, passenger car parking areas and less
used streets (DWA-A 138 chart 1 Points 1 to 5; 1/02).
Maximum collection surfaces
Surface, load
Roof surfaces and terrace surfaces
Streets with <300 cars/d, car parking areas with less traffic, bicycle lanes and
pavement
Streets with 300 – 5000 cars/d
The single surfaces can be combined proportionately. More detailed information is
available with the service.
By parallel connection of several filters the collection surface can be increased.
The installation depth of the filter can be increased by adding a pipe extension (order No.
RWZT2153; technical documentation DORW3108).
2. Function
by bit by the bigger impetus which rises (coalescence effect).
Because of the design of the filter case – remobilisation, the large entry pipe and the
mesh width of the filter (size of maximum 0.5 mm)- heavy rainfall will not impair the
quality of filtered water.
Maxi Plus
The rainwater flows through the inflow (A)
into the filter case, then through the
meshes into the filter cartridge (B, mesh
width 0.5 mm) and the cleaned water flows
out through the outflow (C) into the tank.
Particles of a certain size, which are heavier
than the water, settle in the filter case (D).
This settling process is improved by the
retention time and design of the filter
cartridge. Settling of particles lighter than
water is improved by the filter meshes in
which only small particles or droplets, with
accordingly few impetus, stick. Other
incoming small particles or droplets form bit
