Container treatment units

Container treatment units are complete treatment units that have been installed in a steel 10ft or 20ft container. The main components and the equipment are incorporated into the container. Because they are ready for operation, the containers can be rapidly deployed.

Incorporating a treatment unit into a 10- 20-ft container has the following advantages:

minimal mobilisation time, therefore rapidly deployable
fewer facilities required on location
no fencing required
less space required
thanks to insulated walls, no noise nuisance or danger of freezing
less conspicuous than a treatment unit consisting of separate components
the entire structure is sealed, making it vandal-proof
longer life span than a treatment system consisting of separate components.

With regard to the available space inside the container, these units do have a number of limitations. For a system that includes filters, it means that a container treatment unit will achieve a capacity of a maximum of 10 m3/hour.

Fewer limitations apply to installing a stripping tower in a container. As a rule, standard stripping towers, complete with a pump tank and air-side active carbon filter can be installed in a container. Due to the size of the air filter, stripping towers in combination with a biological air filter are more difficult to integrate in a container. This is the reason the biological air filter is placed on or next to the container when the capacity is 10 m3/hour or more.

Features of the container:
A container in which a water treatment unit is being installed is adapted in the following way:

a ventilation grille and the requisite cable and pipe lead-throughs are fitted in the wall
a sealable wicket door is fitted in one of the large container doors
the interior wall is insulated with glass wool, onto which wooden sheeting with a white plastic top layer has been fitted
an aluminium bulb plate floor is fitted (in the case of a 20-ft container)

For filter units:

in the roof, access hatches are fitted for the integrated water buffers as well as hatches to fill the filters. These hatches can be sealed and are supplied with gas springs. A ladder is also supplied.The following are also installed:lighting with a switch and wall socket
a heater with a thermostat
a stainless steel writing board with a document holder
a fire extinguisher, first-aid kit, eye-wash fountain. The standard container treatment unit is finished on the outside in a RAL colour of the customer’s choice or, if desired, in the customer’s corporate colours.
