INDUSTRIAL WASTE WATER (I.W.W.)
A specific apparatus is associated to each treatment.
Tertiary treatment -
Removal of suspended solids and organic substances
-
Oxidation (air, ozone, reagent, …)
-
Coagulation -
destabilisation of
colloidal particles
R.A.P.D. ("Réacteur d'Agrégation de Particules par Destabilisation")
- combined or not with flocculation
- with static or motorised mixer
-
Flocculation -
agglomeration
of particles by transport et contact one with the other. Larger
particles or "flocs" are the result.
R.A.P.T. ("Réacteur d'Agrégation de Particules par
Transport")
- combined or not with flocculation
- with static or motorised mixer
- with or without stirring
- with or without post-treatment
-
Filtration through a
filter-bed
- at air pressure –
"open" filters – for important flows, i.e. for several hundreds of
m³/h. Units usually in concrete
- "pressure " filters –
for limited flows . Units in steel or synthetic material.
-
Filtration on activated carbon
-
Settling with plates (with or
without sludge recirculation)
Solid – liquid separation
is improved by forcing the flow between plates mounted at an angle in
the clarification zone
HYDROPAC CL
HYDROPAC - R CL
-
Filtration on porous
membranes
-
microfiltration
MICROSEP (Micro Filtration)
-
ultrafiltration
-
retention de suspended
solids, colloids, germs,...
ULTRASEP (Ultra Filtration)
-
nanofiltration -
retention de
suspended solids, colloids, bacteria and some bivalent salts, the
monovalent salts are nearly removed.
NANOSEP (Nano Filtration)
-
osmose inverse
-
retention of nearly all
ions, salts, bacteria, viruses,...
-
One-train unit
PERMEASEP
-
Multi-train unit
-
serial
PERMEASEP H.E (Reverse Osmosis High
Efficiency)
-
in
parallel
PERMEASEP H.F (Reverse Osmosis High
Flow)
-
combinated
(parallel and serial)
PERMEASEP C. (Reverse Osmosis
Combi)
