Håkvik avlopsrenseanlegg: vurdering av dagens rensetrin og rensekrav, samt en gjennomgang av fremmedvannets påvirkning på renseeffekten

Abstract [sv]

Håkvik wastewater treatment plant(Håkvik RA) is located in Håkvik in Narvik municipality in Northern Norway. The treatment plant is designed as a chemical/biological treatment plant with chemical precipitation and a rotating biological contactor. The effluent from Håkvik RA is in the mouth of the river Håkvikelva with an outlet across a long shallow beach. At present 650 pe is connected, but the treatment plant is designed for 900 pe. The objectives of this work were to evaluate the treatment processes, to study the daily management of the treatment plant, and to investigate how alteration executed at the treatment plant affected the efficiency of the treatment processes. Another purpose of the study was to investigate which effect stormwater inflow (rain, spring flood etc.) has on the efficiency of the treatment processes. Furthermore, the costs for reconstruction of the sewer pipe network were analysed.
