On the distribution of saline groundwater in the Poopó Basin, Central Bolivian Highland
Lake Poopó is a terminal lake of the Bolivian Altiplano, with high salinity and heavy anthropogenic pollution from centuries of extensive mining activity. This study aims to describe how the water quality of groundwater and surface water system in different subwater-sheds of the Lake Poopó varies with geology and hydrology. Measurements of total dissolved solids […]
Biological sludge liquor treatment at municipal wastewater treatment plants – a review
Separate biological treatment of sludge liquor, produced when dewatering digested sludge at wastewater treatment plants, can be favourable in achieving sufficient nitrogen removal. The treatment has the potential to decrease volume requirements and electrical energy and external carbon consumption. The characteristics of sludge liquor (high temperature, high ammonium concentration, low COD:N ratio) support high autotrophic […]
SLUT I KRANEN? EN STUDIE AV KONTINUITETSHANTERING FÖR DRICKSVATTENBRANSCHEN MED FOKUS PÅ NÖDVATTEN OCH STANDARDEN BS 25999 / No Tap Water? A study of Business Continuity Management for drinking water suppliers with focus on BS 25999 and emergency situations
The access to safe drinking water is a basic and critical component of our society. If the drinking water supply system is exposed to disturbances, it is of great importance that water suppliers are able to maintain continuity within the water distribution system. This study analyses if the emergency planning of Swedish drinking water suppliers […]
SLAMAVATTNING MED KEMICOND® OCH HYDRAULISKA KOLVPRESSAR PÅ KÄPPALAVERKET / Sludge dewatering with Kemicond® and hydraulic filter presses at the Käppala WWTP
At the Käppala wastewater treatment plant (WWTP) in Stockholm, a novel approach for dewatering of sewage sludge has been developed. As in many wastewater treatment plants the dewatering is a costly part of the treatment process. The sludge produced at the plant must be hauled to be used on farmlands and dewatering greatly reduces the […]
Uncertainty and Good Practice in Hydrological Prediction
All forms of hydrological prediction involve many different sources of uncertainty. Many of these sources of uncertainty involve knowledge (epistemic) uncertainties that are not necessarily easy to represent statistically. This can create problems for communication and interpretation between modeller and users when uncertain predictions are presented. One way of dealing with this problem is to […]
Analys av översvämningar i ledningsnät i Kungshult – effekt av klimatförändringar / Analysis of the sewer network in Kungshult – effects of climate change
Flooding in urban areas has increased and due to this fact extensive research about the effects of climate change on extreme rainfall is being done. This study is an attempt to determine how large the increase of extreme rainfall will be in Scania, Sweden. Through a literature study it is found that the recurrence interval […]
