OBJECTIVE: to analyze the fluoride concentration in the public water supply at the area supplied by the Water Treatment Station of Bauru and classify the samples as acceptable or unacceptable according to the fluoride concentration. MATERIAL AND METHODS: samples were collected from 30 areas at two periods, October 2002 and March 2003. The fluoride concentration in the samples was determined in duplicate, using an ion sensitive electrode (Orion 9609) connected to a potentiometer (Procyon, model 720). Samples with fluoride concentration ranging from 0.55 to 0.84 mg F/L were considered acceptable, and those whose concentration was outside this range as unacceptable. Data were analyzed by descriptive statistics. RESULTS: the fluoride concentration of the water samples varied between 0.31 and 2.01 mg F/L. Nearly 56% of the samples were classified as acceptable. CONCLUSION: the variations in fluoride concentration at the area supplied by the Water Treatment Station reinforce the need of constant monitoring for maintenance of adequate fluoride levels in the public water supply.

The aim of this work was to investigate magnetic field (MF) usage for urban water treatment. Currently, the popular method of ground water purification includes water aeration and filtration, which are expensive and energy intensive. MF is not used for drinking water treatment but mostly for boiler and cooling water at industrial water plants or in farming for plant growth. The authors decided to test it at a small water treatment station in Poland. An MF generator was placed on the pipe between raw water intake and aeration. The results proved higher efficiency in water treatment, especially in hardness, turbidity, Fe, Mn and NH4 removal.

Two projects of water treatment for public water supply were developed and operated by using combined systems of constructed wetlands. One of the projects was carried out in the town of Analândia, São Paulo, Brazil and wetlands with floating aquatic plants associated to the HDS system were used. Nearly 6,480 inhabitants were supplied. The other conducted project was an experimental station in partnership with SABESP (São Paulo State Sanitation Agency / Brazil), for the pretreatment of 1,700 l.s−1 of waters from the Cotia River, which is used for the population's supply after conventional treatment at the Lower Cotia Water Treatment Station. For this pilot project, wetlands with emergents and floating plants associated to the HDS system were used. The proposed objectives were achieved in both projects.

Purpose. To determine composition and properties of iron-manganese crusts formed on grainy filtration load granules surface in the process of underground waters cleaning from Fe2+ and Mn2+, and to determine the application limits and perspective trends of the offered water preparation technology development, conditioned by the properties of these crusts. Method. For the analysis of physical and chemical properties of iron-manganese crusts analytical methods are used on the base of leaching and determination of iron and manganese content in solution and for more precise definition of crust qualitative composition an X-ray fluorescent photography spectrometry is used. For determination of crystalline structure an X-ray photography diffractometry was used, and the thickness of film was determined by mechanical micrometry. Processing of the received information and graphic interpretation of data is executed with application of LibreOffice Cacl, Gnumeric and PSPP software. Results. Determined physicochemical characteristics of iron-manganese crust formed on granules surface of grainy filtration load, the metrical sizes of film are determined: thickness and mass, analytically determined by lixiviating contents of iron and manganese in a crust. Manganites, that form a crust, are dispersion characterized; on some occasion considerable amount of roentgenoamorphous phase is formed, and in other - a crystalline form predominates as todorokite. In our opinion, it is determined by correlation of Mn/Fe concentrations in initial water. Results of crust measuring on the granules of filtration load on the water treatment station in town of Uzin is the following: thickness 0,518±0,209 mm; mass 0,0039±0,0004 g, manganese contents and total iron, accordingly, 115,59±4,33 mg/dm3 and 55,33±30,85 mg/dm3. Manganese and iron contents, which were lixiviated from the crusts of filtration load on the water treatment station in Chervona Sloboda village, accordingly: 55,067±10,946 mg/dm3; 100,476±4,284 mg/dm3. Scientific novelty. Firstly possibility of forming catalytic crust (film) from iron-manganese compositions on the filtration load surface is experimentally proved, among those compositions there are higher oxides of manganese in considerable volumes. Having determined their crystalline and chemical structure, it was proved that they provide the effective removal of iron and manganese over the norm contents from water and in a perspective can be used for the removal of a number of low valency cations among which the removal of Ñà2+ and Âr2+ is experimentally confirmed. Practical significance. Based on the known geobiochemical cycles of iron and manganese a new water treatment technology and also a new filter material with considerable potential of subsequent improvement and application are gotten, unlike classic technologies of manganese removal this method does not require bringing in additional reagents at Mn(II) → Mn(IV) oxidation.

This article presents the results of a comparative study of the method of biological treatment using aquatic plants and algae to improve the technology of treatment of domestic and municipal wastewater treatment plants formed in urban areas. According to test results, 5 species of aquatic plants and 2 strains of algae tested, pistachio and eucalyptus species, and strains of Chlorella vulgaris UA-1-6 were found to be resistant to domestic wastewater. This water plant laripistiya and eichorniya species grow well in different wastewater concentrations (25%, 50%, 100%) in the 100%. Both water treatment stations have a high yield and treatment levels. It was observed that it reached 90% at the "Binokor" water treatment station and the water treatment station "Salar" - 82-86%. This is because the amount of harmful substances in the wastewater of the "Salar" water treatment station is 5 times higher than the number of pollutants in the water treatment station "Binokor". It should be noted that the results of wastewater treatment works at 2 water treatment plants showed that the type of pistachio plant is more resistant to wastewater than the type of eucalyptus, and the level of treatment is also high. Therefore, in the experiment at the "Salar" water treatment station, we found it necessary to use the pistachio water plant itself. At this wastewater treatment station, wastewater treatment reached an average of 84%, and to increase the treatment efficiency, we grew Chlorella vulgaris in the second treatment stage and found that the treatment efficiency was 90-92%. This means that the treatment of wastewater in each treatment station requires the development of biological treatment technology following it.
