5.3.1. Additive: corrosion protection "hebro®protect 95-103" (optional)
A corrosion-protective agent should be added to the water in order to prevent the formation of rust,
especially in case of separation of acidly reacting substances. This is primarily required when separating
metal dust and scale dust.
If you ordered a corrosion-protective agent when ordering the unit, add it to the water when
commissioning the unit.
As water is refilled from time to time, the corrosion-protective agent must be refilled in small doses as
well (in case you use a corrosion-protective agent). The water consumption (see chapter "Technical
data") depends on several service factors and must be observed or determined individually for each
unit. For a successful use of the corrosion-protective agent it is important that it is added to the water in
a mixing ratio of about 1:30 to 1:100. This can be carried out in two ways:
● manually: by refilling it regularly
● automatic dosing: by using an optional dosing device
The corrosion-protective agent and, if required, the dosing device can be ordered directly from the
company Hebro Chemie: tel.: +49 2166 6009 – 0, e-mail: info@hebro-chemie.de
5.3.2. Additive: Defoamer (optional)
The defoamer releases foaming that is produced by certain types of dust. The dust bonds a certain
amount of the defoamer so that it can be necessary to refill some defoamer, depending on the amount
of dust. You can manually add defoamer via the ¾” T-piece (pos. 7) (about 12,5 ml defoamer per 100 l
fresh water). The exact quantity has to be determined via trials. (Defoamer is available on option).
5.4. Installing a water discharge as an overfill protection
The wet separator is equipped with a mechanical overfill protection in order to protect it from too much
water supply (e.g. due to defective magnet valves). When the wet separator exceeds a certain level (B),
the excess water drains off through the opening of the hose (A).
To prevent the water from spilling on the floor in case of overfilling, the operator must install a water
discharge under the opening (A). The water retention can e.g. be done by a hopper. The water
discharge should not be connected directly to the opening (A). Otherwise it might not be possible to
recognize water leakages during a visual inspection.
