Response to variations in nutrient inputs to the southern estuary of river Göta älv on the Swedish west-coast is investigated by means of estuarine nutrient and chlorophyll (Chl-a) data from 1990–05. The estuary receives nutrients from the river, and from the Gothenburg Waste Water Treatment Plant (WWTP). Since 1972, when the WWTP was built, the […]

Biological nitrogen removal by the use of Sequencing Batch Reactors (SBR) is today an accepted and well proven model. The Nowy Targ SBR plant has been in operation for 15 years, and comprehensive performance data are available for assessment. This paper focuses on the 2005 year operation, characterised by high organic and nitrogen loading and […]

In this study, a comparison between Moringa Oleifera MO and aluminium sulphate was conducted for coagulation of turbide water using jar test. The optimum coagulant dosage was investigated for different levels of turbidity, and the impact on treated water properties monitored. Use of MO together with direct filtration was also investigated. Coagulation with aluminium sulphate […]
