Transportable & Relocatable Wastewater Treatment Plants
A recent addition to OHW range of wastewater treatment options is
the engineer designed purpose built transportable & reusable STP.
Fully approved construction by Lloyds of London, these Plants are
housed in 20’ and 40’ containers to facilitate sea borne and road
The treatment capacity of the Plant will vary from project to project depending upon the constituent load contained
in the wastewater stream. Given that many mining and construction
applications are often located in areas with very high daily temperatures,
it is not uncommon to have a per capita water consumption of
300 litre in some instances. In other areas of a more temperate nature,
water consumption of 150 litres per capita is more the norm.
However, as a general rule, given a ‘domestic strength’ wastewater
quality, the following treatment capacities could be used as guidelines:-
The standard configuration of the transportable unit is designed to produce a B class effluent quality that in most instances will satisfy the on-site disposal requirements of the local and State authorities.
If however the requirement is for class A effluent to be used, for example for toilet flushing, dust suppression and the like, where human contact is probable/possible, then a superior quality of effluent is demanded, which will require additional Plant capacity to facilitate tertiary polishing.
All transportable Plants can be fitted with either Chlorine or UV or both for the disinfection/sterilization of Pathogens. Ultimately, the chosen option will be based upon customer and regulatory preferences or requirements.
Commissioning & Decommissioning
Transportable Plants arrive on site set-up and ready to connect
to the power supply and the incoming drainage line, and are
ready to receive wastewater immediately. The pumps, MCC and associated equipment
arrive at the same time, all mounted in a 6’ container (pump shed) ready for connection, or alternatively, these components
can be incorporated within the structure of the Plant itself.
However, commissioning of the Plant with an
OHW staff member present is preferred where possible as on the spot training of the Customer’s representative can
take place. Once the project has been completed, the Plant can be quickly decommissioned either by OHW staff or
the Customer’s staff and is then ready to be collected and moved to the next project or placed in storage. Snap on/
snap off connections make commissioning and decommissioning the Plant a quick and simple task.
Residual effluent can be removed by tanker if available, and if not, the use of a ‘Geotube’ or similar is
Storage & Handling
The Plants are fully stackable and come with the usual lifting eyes, stacking lugs and forklift slots.
Approximately 3-4 weeks from time of order.
