Many phytoplankton species are notoriously motile, fragile, difficult to preserve, and difficult to identify in preserved samples. Microscopical examinadon ofliving phytoplankton material has several advamages, though it often demands great patience. Species identification is easier and it is possible to observe e.g. life cycle, pigmentation, motility, particle uptake and some food web relationships. Rare, fragile […]
Many attempts have been made and are under investigarion in order to create artificial-life. Farfetched experiments have been piloted based on classical electro-mechanical and dynamical iheories. Yet none have revealed any sign of life emerging from lifeless matter. On the contrary, life through the interference of water always evolve from life.By interweaving known theories a […]

In order to study the possible contamination of drinking water supplies with pesticides, the National Food Administration carried out an invesrigarion in 33 water supplies during 1992-94. Sampling was done both in surface and ground warer supplies. Pesticide residues were found in three ground water supplies on all seven occasions and in one surface water […]

Biological nutriem removal by means of the SBR technology has become acknowledged also in Europe during the last few years, after its breakthrough in the US and Japan some 10 years ago.This paper presents the performance of three modern SBR plants in Europe, all operated for advanced removal of BOD, total N and P. The […]
During the waste water process, coagulants are used to remove phosphorus and BOD and to stabilise the process. The coagulants will accumulate in the sludge mainly as metal phosphates and a minor portion as metal hydroxides. These elements will influence the behaviour of the sludge when it is disposed of on agricultural land.The availability of […]
The environmental problem with water treatment sludge is small, but utilisation of the sludge for production of aluminous cement may reduce the problems, since any environmental hazardous contaminants is bound as mineral to the building material and mining of raw material for cement production is reduced. Compression strength were measured after different hydration lime on […]
