The Senior Pureflow Package Sewage Treatment units are designed to treat wastewater flows for populations of up to 250 persons, producing an effluent to comply with discharge consent limits for BOD's, SS and nitrified effluents.
The Senior Pureflow System incorporates 'Submerged Aerated Media' to provide a high quality biological treatment process. The compact unit contains primary sludge settlement, biological treatment and final settlement in a single GRP structure.
The Process
Sewage entering the Senior Pureflow flows through a two stage primary settlement compartment to ensure sufficient settlement time for gross solids. The separated liquor entering the biological compartment mixes with aerated liquor already undergoing treatment by re-circulation through a submerged plastic filter media. Micro-organism activity is encouraged by fine bubble diffusion and full aeration of the media. The treated liquor then displaces into the final baffled settlement compartment before discharging to a receiving watercourse or percolation area. An automatic air lift system returns settled humus sludge from the final compartment back to the primary and biological compartments to assist the process.
The entire process is achieved using a surface blower housed in a weatherproof kiosk. Senior Pureflow units are designed in accordance with BS6297 to meet the strict effluent discharge standards set by local authorities, while also giving careful consideration of ease of maintenance and health and safety matters.
