Catalogue

Community water purification

From villages to cities: automatic purification of borehole, surface, rain and mains water, with solar autonomy available.

POTASOL

Water purification container

Ready-to-install 10 or 20-foot container for villages, schools, hospitals, hotels, base camps and refugee camps. Regulated 0.01 µm ultrafiltration or UVc, with no reagent other than chlorine.

5 to 150 m³/h depending on model
Integrated 8 m³ storage
Solar autonomy or battery backup
Automatic coupling to the DCE water tower

DP3UF

Ultrafiltration plant

Automatic plant installed at a building's water inlet (mains, borehole, rainwater or tank). No chemicals, 0.01 µm membranes, made in France.

1,000, 2,000 or 3,000 L/h (DP3000/2, /4, /6)
2, 4 or 6 membranes of 0.01 µm
Automatic timer-controlled backwash
Service life of 7 to 10 years

BUILDING PACK

3 m³/h, i.e. 30 m³/day
Chlorine and level alarm
UVc steriliser option
Multilayer sand filter option

DP3UF in detail

Panel of the DP3UF ultrafiltration plant

Fully automated, autonomous membrane ultrafiltration of mains, borehole, rain and tank water (maximum 4 bar and 35 °C). Robust design, made in France. The plant is installed indoors at the main water inlet, for houses, hospitals, clinics and hotels connected to a network, a well or a tank that may present bacterial contamination and suspended solids.

A 130 µm pre-filter protects the membranes, whose 0.01 µm pores retain suspended solids, bacteria, protozoa and pathogens. The water must be clear, non-brackish and under pressure; pre-filtration is required for river and lake water.

Advantages

No chemicals: reliable, instant treatment.
Polysulfone hollow-fibre membranes.
Outside-in dead-end filtration: low water loss, large filtration surface, extended service life.
Very low consumption: no electricity is consumed during production. A timer automatically triggers the membrane backwash.

Technical specifications

Model	DP3000/2	DP3000/4	DP3000/6
Capacity	1,000 L/h	2,000 L/h	3,000 L/h
Membranes	2	4	6
Type	Autonomous water purification plant
Technology	Outside-in dead-end filtration, 0.01 µm
Service life	7 to 10 years depending on maintenance
Connection	Pressure of 2 to 4 bar; 220 V single-phase, 50 Hz, 16 A (consumption for solenoid valves only)

Capacity decreases with turbid water. Option: cyclonic filtration kit, which pre-filters turbid water.
