In Harelbeke a Water Treatment Plant with a capacity of 15,000 m3/day, using Schelde river water has been in operation since April 1995. The treatment process comprises nitrification, dephosphatation by direct filtration, storage into a reservoir, direct filtration, granular activated carbon filtration and disinfection. The design of the three-layer direct filters was based on pilot experiments. The performance of the plant during the five years of operation is discussed. It was found that the removal of atrazin by activated carbon depends on the water temperature.

Overall Risk

There is increasing pressure from financial and quality regulators both to reduce costs and to improve levels of service within the water industry. It is possible to reduce costs to some extent without affecting levels of service unduly. However, there comes a time when further reductions have a major impact on the reliability of the treatment process and the reductions are no longer cost-effective. On examination, it is typical to find that the overall risk of treatment failure is dominated by a small number of significant problem areas or pinch-points within a system. Removal of these pinch-points through design or operational changes will lead to improvements in levels of service. Alternatively, if the pinch-points dominate the risk and cannot be removed cost-effectively, there is little point in over-protecting other areas through the inclusion of standby equipment or with unjustified levels of maintenance. Thus costs in these areas can be cut back without unduly increasing the overall risk of failure. This paper shows how risk analysis can be used to identify those areas of a system that dominate its risk of failure. This allows its design and operation to be optimised, thereby enabling levels of service to be met at minimum cost.

Irrigation Network

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.
