Portapura

Portable sewage treatment plants

Portable, compact, efficient sewage treatment solutions for temporary buildings

The Portapura is the most compact and efficient sewage treatment plant we’ve ever made.

Designed for temporary accommodation, site offices, site toilets and workshops, the Portapura is portable, can be installed above or below ground and treats domestic wastewater to a level that is 25 times better than the recommended EN standard.

Why choose Portapura?

It’s more efficient than other sewage treatment options… And more portable than all of them.

It’s a space-saving solution… Its compact design provides quick and easy installation with minimum visual impact on the surrounding landscape as well as simple and safe access for maintenance and cleaning.

It’s cost-effective… The cost of installing and running the Portapura is minimal when compared to larger, commercial systems.

It’s environmentally sensitive… CE approved to BS EN 12566 with an ammonia result that is 25 times better than the recommended EN standard means the Portapura is well within discharge consent requirements.

It’s designed specifically for temporary buildings… Design objectives included performance, running costs, installation, transport and storage, making the Portapura the logical choice for sites where temporary buildings are required.

Portapura sewage treatment plant

Wastewater enters the primary settlement chamber [A] where large solids are removed by settlement and flotation. An accumulation forms at the base of the tank and is removed by desludging

The clarified water is then transferred to the main aeration chamber [B]. Here it is treated to remove dissolved constituents. Aerobic bacteria, supported by diffused air, ensures full treatment is achieved before the effluent and ‘sloughed off’ bacteria flows to the filter chamber [C] for further solids removal.

The final effluent is then discharged to a water course via the final settlement chamber [D].
