Over the past four decades, an increase in Dissolved Natural Organic Matter (DNOM) and colour, commonly referred to as browning, has been noted in numerous watercourses in the northern hemisphere. Understanding the fluctuations in DNOM quality is a p

Several actors have an impact on the quality of drinking water, but ultimately drinking water treatment plants (DWTPs) play a decisive role in ensuring that water quality complies with public regulations. Several developing technologies are combined

Increasing levels of dissolved organic matter (DOM) in watercourses in the northern hemisphere are mainly due to reduced acid rain, climate change, and changes in agricultural practices. However, their impacts vary in time and space. To predict how D

The mesophilic anaerobic treatment of concentrated sludge from an Atlantic salmon smolt hatchery (total solids (TS): 6.3-12.3wt%) was investigated in a continuous stirred tank reactor (CSTR) at 35 degrees C and 55-60 days hydraulic retention time (HR

The moving bed biofilm reactor (MBBR) was developed in Norway in the late 1980s and early 1990s. It is covered by several patents and has been a huge success world-wide for treatment of municipal and industrial wastewaters. In addition, MBBRs have be

Optimisation of the coagulation step in a coagulation/direct filtration process in which filtration takes place in a lightweight expanded clay aggregates (Filtralite) filter is investigated. The water is high in NOM but low in turbidity, a situation
