Package Sewage Treatment Plants (or PSTP's) are often a suitable option where groundwater in the surrounding environment is vulnerable, drainage field percolation values are restrictive, or direct discharge to watercourse or surface water sewer is the prefered discharge method. Marsh Industries ENsign range of sewage treatment plants treat final effluent to British and European Standards to allow it to be discharged back into the watercourse whilst reaching national consent standards. Our tanks can be manufactured with either a gravity or pumped outlet to meet your site requirements.

In addition to the anaerobic digestion taking place in the primary settlement tank (as septic tanks) the Microbe unit allows the clarified water to pass into a second 'aeration' chamber where it is treated to remove the dissolved constituents. Here aerobic bacteria, supported bu diffused air and mobile media, ensure full treatment is achieved before the treated effluent (and 'sloughed off' bacteria) flow to a final settlement chamber prior to discharge.

Microbe Benefits

• As with Marsh’s larger Ensign range, the Microbe is designed to BSEN12566:3 to comply with latest environmental and Building Regulations requirements*

• Compact design for ease of handling, access and installation enables suitability for all site conditions including bedrock or high water table
• Low energy compressor ensures minimal running, maintenance and servicing costs
• Internal recirculation (from final to primary chamber) continues treatment process to provide higher effluent quality whilst balancing flow over 24 hour period or periods of intermittent use
• Unique ‘keying-in’ lip to assist anchoring into granular or concrete surround
• Optional extras include patented Polylok filter to further reduce suspended solids and extend life of drainage field; extensions for deep installations; pumped outlets for sites with adverse levels; and many more
