There is an urgent need to develop and improve low cost technologies for wastewater treatment. Simultaneously treating wastewater and producing duckweed in a pond system is, therefore, an attractive solution contributing to both environmental protection and food production. Duckweed has excellent qualities: a high protein content, a high growth rate and is an easy crop to handle. The small plant turns nitrogen from wastewater into a food source. This thesis reports on the effect of different operational variables, like anaerobic pre-treatment, the combination of algae and duckweed ponds and pond depth. Improved nitrogen removal was obtained through the combination of duckweed ponds with algae ponds. Duckweed pond systems could be designed with shallow depth without affecting nitrogen removal efficiency. This research is the result of the cooperative effort between the EIDENAR, Univalle, Cali, Colombia and the UNESCO-IHE Institute for Water Education in Delft, the Netherlands.

The demand on land to produce food, for urban development such as housing, industry, shopping areas, infrastructure and also for recreation has increased during the history of mankind. This has resulted in such activities as the reclamation of swamps, flood plains, tidal areas and even lakes by impoldering. Model simulations can be use to gain insight into the system behaviour of different land use and soil composition under temperate humid and humid tropic conditions, The existing package OPOL, based on a non steady model, was further developed to the version OPOL5 for the simulation of hydrological conditions and optimization of the main components of water management systems in polder areas in the temperate humid and humid tropical zone. This model reveals a system's behaviour as well as the effects of variation in the main components of the systems to the overall costs. For example, the designs of pumped drainage systems in polder areas can be optimized by varying the main components until the annual equivalent costs are minimum. A GIS tool has been used to complement OPOL5 for the simulation of the real situation in an area with respect to land use, damage, topography, and soil type. The model package has been applied to two case studies: one in the temperate humid zone, namely the Netherlands and to Thailand in the humid tropical zone.

This 6th volume in a 19-volume series contains 21 letters written by van Leeuwenhoek of the perod 1686-87. The contents of the letters published here, again show the great range of subjects that occupied Van Leeuwenhoek: from sugar candy, the shape and crystal structure of diamonds, the dissolution of silver crystals in aqua fortis to gold dust from Guinea dissolved in aqua regia and the dissolution and separation of gold, silver, and copper. Every volume in the Series contains the texts in the original Dutch and an English translation. The great range of subjects studied by Van Leeuwenhoek is reflected in these letters: instruments to measure water, pulmonary diseases; experiments relating to the solution of gold and silver; salt crystals and grains of sand; botanical work, such as duckweed and germination of orange pips; description on protozoa. blood, spermatozoa and health and hygiene, for example and harmfulness of tea and coffee and the benefits of cleaning teeth.

Het boek van Henoch Volgens de Bijbelse chronologie was Henoch de zoon van Jered en de vader van Methusalah. Hij werd geboren in het jaar 622 na de schepping van Adam, toen zijn vader de leeftijd van 162 jaar had bereikt. Zijn naam betekent zoveel als "De ingewijde" "De inzicht hebbende" en "De kenner". Henoch werd zonder te sterven van de aarde weggenomen in het jaar 987 toen hij 365 jaar oud geworden was.

Effective treatment of nitrogen containing wastewater is required to prevent eutrophication and groundwater pollution. This thesis shows that effective treatment may be combined with substantial nitrogen recovery in duckweed-based waste stabilization ponds.
