1.1 Use
Special equipment must be used to pre-
vent harmful substances which corrode
the materials used for draining elements
or disturb operation from entering the drai-
ning system in the first place. Sand and
sludge traps are used where wastewater
containing sediment is discharged into the
draining system.
One quite unusual application of the provi-
sions in DIN 1986, Part 3, "Impermissible
use by setting substances" concerns the
use of plaster in the dental, surgical and or-
thopedic treatment areas of hospitals, clay
in school handicrafts lessons etc.
1.2 Dimensioning
The size of the sediment separator must be
dimensioned according to the volume and
type (e.g. plaster, scale, synthetic resin,
168-001
General
glass) of the washwater to be discharged.
The following criteria must be taken into
account
- Washwater drain
- Density of the heavy materials
- Quantity of heavy materials to be
discharged
Accordingly, empirical values allow wash-
water flows to be matched to the nominal
sizes as follows:
0.5 l/s flow = NS 1
1.0 l/s flow = NS 2
1.3 System description
The KESSEL sediment separators EasySink
free NS 1 and 2 are made of PE-HD and are
thus absolutely corrosion-free. They stand
out on account of their compact design and
can be set up directly where the sediment
occurs.
The systems are delivered completely as-
sembled and are immediately ready for
immediate operation. The collecting tanks
Einbau- und Bedienungsanleitung
can easily be removed from the separator
for disposal of the contents and cleaning.
The inlet and outlet of the KESSEL sedi-
ment separators EasySink free has been
designed for connection of SML pipes ac-
cording to DIN 19522
1.4 Disposal
The first disposal must be carried out within
2-3 weeks of initial operation.
Disposal intervals: Disposal must be car-
ried out when the collecting tanks are half
full at the latest.
Please check the filling level of these col-
lecting tanks at regular intervals to guaran-
tee perfect separating efficiency.
The systems and collecting tanks must be
filled with water up to the overflow after
every disposal process.
