Applications
- Principally used to treat surface water,
Applications
UCD®, DEGREMONT Compact Unit, is
a complete self contained drinking water
treatment plant
- Short delivery time and simple site
installation provide drinking water
production for small and medium size
cities quickly and easily
UCD® drinking treatment plant is based on
compact conventional process: coagulationflocculation, lamellar clarification, sand filtration
and chlorine disinfection.
MAIN FEATURES
A range of 14 units, producing from
5 up to 720 m3/h
Single skid systems for up to 30 m3/h
Skid modules for 50 up to 720 m3/h
Pre-assembly in our workshop offers reliable
and fast erection on site
Treated water delivered at 2 bars
(standard version) or more
A complete reagents skid is provided,
including preparation and dosing devices
Self contained, UCD® includes all washing
facilities: no need for separate backwash
water tank
UCD® SPECIFIC TECHNOLOGY
UCD® has been developed, keeping in mind operation and
maintenance constraints. Clarifiers sludge extraction is automatic.
UCD® can be ordered with automatic or manual filters backwashing.
Automation is based on relay type actuation, which is very simple to
maintain in remote areas. Several options are available taking into
account water treatment requirement (aeration, pre-oxidation, UV,
active carbon filtration, etc.) and reagents available in the country.
Other equipment can be supplied such as: automation based
on PLC, raw water pumping station, higher pressure delivering
of treated water, booster pumps, treated water reservoir, mobile
system (5 to 20 m3/h).

HOW IT WORKS
Coagulation-Flocculation
Settling
After a coagulant is applied, the raw water flows into a flocculation
chamber to increase the size and cohesion of the floc.
A clarifier equipped with lamellar modules is used to accelerate
the separation of the floc. The sludge stored in the lower position
of the separator is withdrawn automatically at regulars intervals.
Water is transferred from the flocculation compartment to the
settling tank via a stilling chamber located beneath the lamellar
modules. Settled water is collected in the settling tank overflow
and pumped to the filters.

UCD PRINCIPLE DIAGRAM
Reagent skid
Pressure filtration
Inside the filters, water is distributed above the filter media and
flows down through the sand, which traps the suspended solids.
Nozzles fitted on the filter floor collect the water evenly and then
discharge it directly towards the treated water tank, following the
application of a disinfection agent.
Product Highlights
Compact
Fast installation
Water and air scour
Skid mounted modules
Backwashing uses filtered water from the operating filter,
coupled with air scour. This design:
Reliable
Easy to operate and maintain
• Cleans the filter media thoroughly
• Minimizes the duration of the backwash cycle
• Eliminates the need for a backwash water tank and pump.
Adapted to local conditions
Lamellar modules settling
Simple concrete work required
