This paper presents the methodology used for the rehabilitation of the pretreatment stage in a water treatment plant for a village located in Bolivia which has 3500 inhabitants. The treatment plant was initially composed by horizontal-flow roughing filters and slow sand filters, but due to the high contents of colloidal turbidity of the providing source, it did not work properly. A plan of rehabilitation was made which comprised laboratory tests, pilot tests and proposal of modifications based on the results of previous stages. The laboratory tests were made in order to find the optimum conditions to coagulate the raw water. It was found that horizontal-flow roughing filters must be turned into up-flow roughing filters, so a pilot plant was built and was operated for three months in order to find suitable design parameters. The results obtained obtained during the operation of the pilot plant and the proposal of modifications are presented. The results of operation of the final plant, which are also reported, demonstrated the advantages of the up-flow roughing filtration as a pretreatment stage when it is necessary to add chemical products in small treatment plants.

Treatment Step

The performance of a drinking-water treatment plant is determined by the control of the plant. To design the appropriate control system, a control-design methodology of five design steps is proposed, which takes the treatment process characteristics into account. For each design step, the necessary actions are defined. Using the methodology for the pellet-softening treatment step, a new control scheme for the pellet-softening treatment step has been designed and implemented in the full-scale plant. The implementation resulted in a chemical usage reduction of 15% and reduction in the maintenance effort for this treatment step. Corrective actions of operators are no longer necessary.

The Vaalkop plant, owned and operated by Magalies Water, provides a valuable South African case study of sludge and washwater management at a large water treatment plant. Starting out as a small plant of 18 Ml/day about thirty years ago, it has steadily grown to a plant with treatment capacity of 210 Ml/day; fairly large by South African standards. During the preceding years, it has not only been subject to a vastly larger scale of operation, but it also had to adapt to a tremendous increase in the cost of raw water, an increased environmental awareness amongst water treatment professionals and general public alike, and a much more sophisticated and complicated legislative framework. It is the objective of this paper to track the sludge and washwater management practices adopted over the years at Vaalkop, and to present the current strategies adopted for the medium to long term. The paper will summarize the previous methods of sludge and washwater disposal, with reasons why they were adopted. The multitude of technical analyses and alternatives that were performed over the years will be summarized, and may provide valuable pointers for other applications in South Africa. The current system, which has just been commissioned, will be presented; its technical design parameters, the anticipated mode of operation, its costs and how the current environmental and legislative requirements are being met.

AbstractSilica scaling deposition in industrial water systems is one of the biggest challenges facing the water treatment industry due the low solubility of the scalants in the feed waters. In this preliminary work, we investigated the effectiveness of the ionizing radiation induced removal of silica in water sample from the Salbukh, Saudi Arabia, water treatment plant by using metallic iron as the source of ferric hydroxide to co-precipitate the silica. The influence of several reaction parameters, i.e. iron powder dosage, radiation dose, initial pH and equilibrium pH effect were investigated. In the optimum conditions, up to 75% of silica was removed. This preliminary study showed that this environmentally friendly process is effective in silica removal from underground water.

After 2003, hundreds projects were completed to provide drinking water to rural areas in most governorates in Iraq. These projects consist of the package water treatment plant, which treats surface water from the Tigris and Euphrates rivers. All the package water treatment plant contains a mechanical flocculators, which suffers from continuous faults and needs periodic maintenance and needs electric energy to operate, which leads to an increase in the cost of water production and lack of quality of water produced. In this project, the possibility of changing the type of flocculators from mechanic to hydraulic was tested for a 100 m3·h–1 package water treatment plant in the Al-Eskan water treatment project in the south of Diwaniyah city in Iraq. There are many challenges facing the design involving findings ways to improve the effi ciency of the flocculation system. Computational Fluid Dynamics (CFD) package, ANSYS Fluent 16.1 software have been used to simulate turbulent fluid flow in hydraulic flocculators for Al-Eskan package water treatmen plants (EPWTP). The flocculator simulations in ANSYS Fluent are used to obtain turbulent kinetic energy dissipation rate to determine the distance between baffles, the quantity of baffles, velocity gradient, residence time, and flocculation performance. The results obtained from ANSYS Fluent simulation are used in designing a hydraulic flocculator, so our finding can be utilized to validate the hydraulic flocculator model. The results confi rmed that the method used to design certain parameters of the tank are fairly accurate. Overall the design of the flocculation tank produced reasonable results which match expected results of hydraulic fl occulation tanks found in literature. The results of the report suggest that a height to baffl e spacing ratio of 22.5 creates intersecting energy dissipation regions that produce the greatest formation of fl ocs per reactor volume.
