THE PROVITEC DRINK WATER SYSTEMS
Easy installation, elegant design ...
The raw water flows through the connection kit (main valve, pressure reduction
valve, regeneration valve) and the red inlet hose into the bottom of the filter casing.
The pressure regulation system limits the water inlet to max. 2.5 l/min (industrial
model 4.5 l/min).
In the first filter level, the water runs through the gravel bed filter, where a gravel
layer retains suspended particles and sediments. This is when the filtration proper
starts in thedifferent cartridges adjusted to the respective water contamination. The
cartridges are cylindrical containers made of PP plastic and equipped with a
permeable plastic grid on the top and bottom.
“Rinsing” of the filter mechanisms inside the cartridges isavoided by filter fleeces
made of polypropylene needled felt, 200μ. The volume changes of the filter
mechanisms are also balanced by filter fleeces. After complete filtration of all the
chemical substances in the different filter cartridges, the water flows through a
specially prepared medical membrane fi lter, which retains and eliminates
completely all bacteria, parasites and microorganisms. The fi ltration stage is now
finished. Now the chemically and microbiologically impeccable drinking water can
flow through the outlet hose to the tap or outlet fittings.
assembly for regeneration
For regeneration, the filter device is turned upside
down and the hoses are connected in inverse order.
The red inlet hose is connected to the socket on top
of the filter device and the blue outlet hose to the
socket on the bottom of the filter device. The
counter current regeneration guarantees an
optimum cleaning of all the filter mechanisms and
the membrane filters. By means of the inverse
position of the filter device for regeneration, the
contaminants are driven directly out from the
bottom layers of the device.
Not even the gravity of the water affects the stream
conditions inside the filter mechanisms. A detailed
description of the regenerationprocess is to be
found in the user manual.

Regeneration of the filter materials and mechanisms
The PROaqua 4200 drinking water filter is easily regenerated by the user
him/herself, with regular maintenance costs being approx. €2/year. Regeneration
should take place approx. every 3 months; in special cases more often, when:
• the absorption capacity of the nitrate or lime resin is exhausted. Example: In
cases of a nitrate load of approx. 100 mg/l and a consumption of approx. 10 l/day,
regeneration is recommended as from a nitrate leakage of approx. 10 mg/l, which
corresponds to an interval of approx. 12 weeks.
• after a long filtering period, the germ filter is obstructed more and more by bacteria
(this is noted by a reduced flow rate from2.5 l/min to e.g. 1l/min).
• the filter is used for the first time or after a long period of disuse.
• cartridges or membranes have to be replaced.
