Possibility for transport
loading and moving the container
 By using crane and wire or steel chain over 4 pieces upper ISO-edges
 By using crane and wire or steel chain over 4 pieces lower ISO-edges
 Pockets for forklift truck are not foreseen on the container
Please apply the instruction manual of the container manufacturer for transport
loading and moving the container
as well as during preparation of the ground and storing position of the container
Medium connections
The container has several windows
which are equipped with cover and screw. Through these windows the pipes for the mediums and cables for the electrical power are connected with the container
Medium connections Flange EN 1092-1/10/DIN 2576 PN 10
Raw water 2 x DN 80
Waste water 2 x DN 125
Filtrate 1 x DN 125
Drain 1 x DN 125
1 x DN 80
Electrical power supply
Main electrical power supply for the container would be connected to the control panel
which distributes the electricity to the electrical consumers within the plant. The connection of the main cable from the voltage supply source to the control panel must be done by special qualified electrician
Required cable cross section 25 mm²
Required safety fuse (on site) 63 A
Voltage supply three-phase current 400 V
Optional equipments outside of the container
Following equipment is to be placed outside of the container and must be transported separately
Neutralisation tank with agitator
Diameter 2300 mm
Useful volume 5 m³
Agitator rated power 1,5 kW
The system consists of
Raw water supply
pre-filtration
flocculation stage
ultrafiltration
backwashing and chemically assisted backwashing
neutralization
dosing stations
valve terminal
compressor unit
measuring devices
control and piping
The raw water supply is regulated automatically
either via the fill level in the flocculation tanks or via the flow meter in the inlet for ultrafiltration
Prefiltration via a self-cleaning filter with automatic control
The flocculation can take place either in a tube flocculator or in one or two stirred tanks connected in series. There is also the option of connecting the tube flocculator and the stirred tank in series. A feed pump is provided at the outlet of the flocculation container
The ultrafiltration group consists of 8 UF modules which can be operated together as one line or in two lines. The UF modules are provided on a UF rack
which has a compact but accessible structure for monitoring and maintenance activities
The filtrate from the ultrafiltration is stored in a filtrate container. An overflow pipe ensures that there is always a sufficient amount of filtrate available for rinsing in the tank. The filtrate container is equipped with a ventilation filter to prevent contamination from the ambient air
Backwashing by means of a frequency-controlled backwash pump is either time-controlled
when a maximum permissible transmembrane pressure (or minimum flux) is reached or triggered manually. The system is designed so that one line can be operated while the other line is backwashed or dry cleaned
The wastewater from the chemically assisted backwashing – controlled by continuous pH measurement at the outlet of the UF backwashing line – is automatically diverted into the neutralization tank. The pH value of the waste water is continuously measured in the neutralization tank and adjusted to a permissible value by adding acids or alkalis
The dosing stations are located in a separate chemical compartment of the container in the following version
Dosing pallet with dosing pump and fittings firmly piped. The dosing plates are each equipped with a drip tray and transparent PVC splash protection
Power each 1.1 kW

In the air-compressor unit
compressed air is produced for control air of the pneumatically driven fittings and for the membrane integrity test. The compressed air system runs on / off independently through the internally installed pressure switch
The system is designed for automatic operation so that it can be operated on site without constant monitoring of the operating staff
