<p>A wastewater treatment plant comprising an inlet for wastewater which is connected to a primary treatment means 5, the outlet of the primary treatment means being connectable to a downstream submerged aerated filter (SAF) 10. The inlet includes a bypass means 4 to selectively bypass flow form the primary treatment means to the submerged aerated filter. The bypass means being arranged to direct flow to the submerged aerated filter when the inlet flow is particularly higher than normal. Part of the flow may be treated by the primary treatment means and be passed to the environment without contacting the submerged aerated filter. The plant is configured to deal with very high inflow of wastewater, such as in times of heavy rainfall or storms. The primary treatment means may be a sewage works 5 comprising a selection of normal primary and secondary treatments found in sewage/wastewater facilities such as screens, filters, settlement tanks, and biological treatments.</p> |
