Start Up

Natural waters contain organic substances that have a major impact on the quality of water, in particular on its organoleptic properties. They can also change its physical and chemical properties and have a negative impact on the technological processes used during water treatment. There is no doubt that organic substances contained in natural waters have to be removed during treatment processes in order to achieve concentrations consistent with the requirements concerning the quality of water intended for human consumption. A very effective method of organic compounds elimination from water is to use of biologically active filters (BAF). This article presents the results of pilot scale research on the effectiveness of removal of organic compounds from water using filtration through a bed of activated carbon filters, during their technological start-up. The obtained results showed high, more than 91% efficiency of reducing the content of organic compounds expressed by TOC, COD (KMnO4) and UV254 absorbance. The predominant process at the start of the use of carbon filters has been sorption. During the research, the development of biofilm in the filter bed was also controlled. The identification of microorganisms showed the presence of Gram-negative bacteria in the beds of both filter columns.

The Impact

Agriculture, especially livestock, is rated as one of the most polluting industries in the world. In the other hand there is a modern approach to the technology implementation, and is this true that with its usage the impact on the environment is so critical and inevitably leads to environmental catastrophe. It is important to investigate and scientifically substantiate the impact of modern livestock complexes on the environment, especially on groundwater resources objectively,. And only after a number of studies conducted on pig farms with a capacity of 30 and 50 thousand heads per year it would be possible to determine next: is livestock an object of ultra-intensive pollution, or it is an object that does not have a significant negative impact on the environment and is also an economic and food lever of the country. The research was conducted on the example of the company JV LLC "NYVA PEREIASLAVSCHYNY" that is located in two districts of Kyiv region – Brovarskyi and Boryspilskyi. The sanitary protection zone size is 1500 meters to the nearest residential development (MINISTRY OF HEALTH OF UKRAINE, 1996). Projects to reduce the sanitary protection zone have not been developed as there is no need for it. Research of water quality was performed according to State Sanitary Regulations and Rules “Hygienic Requirements to Quality of Water Intended for Human Consumption” “2.2.4-171-10” (State Water Agency of Ukraine, 2010). It was conducted on samples that were taken from 4 artesian wells that are located on the territory of the pig breeding farm № 11. The aim of the research is to identify the impact of the pig breeding farm’s № 11 activity on the underground aquifer and surface water body. To reach this target water samples were collected according to the requirements established in the conclusion on environmental impact assessment from wells in the villages and river. Studies that were conducted during 2020 showed that the quality of water in wells meets the requirements for drinking water. Water samples from wells and ponds showed deviations from the norm up to 10 times. Previous studies did not set a negative impact of the pig breeding farm № 11 on groundwater quality.

The aim of the study is to assess the quality of water from selected recreational fountains in Ciechocinek and Inowrocław health resorts. All analyzed water fountains are characterized by seasonal changes in their discharge. The exceedance of biochemical oxygen demand and chemical oxygen demand values found in the water samples may indicate water contamination with compounds of organic origin getting from the external environment to the basin of the fountain or too little recirculation of water. A significant improvement in water quality was noted in fountains in which water exchange occurred due to, for example, its failure. In addition, the water was characterized by a relatively high content of general hardness and conductivity. Reported exceedances of water quality parameters disqualify it for direct human consumption. It does not meet the requirements for drinking water. It is recommended to introduce supervision over the quality of water from fountains by the bodies of the State Sanitary Inspection in the form of water monitoring in order to eliminate from the water compounds that may have a negative impact on human health. It is recommended to regularly use pre-filtration, chlorination and sodium hypochlorite in water in fountains to eliminate physical impurities.

This study deals with the potential use of water stored in a lake formed by Reocín’s old zinc mine, which has become the second most important reservoir in Cantabria, with a flow of 1300 L s−1. The methodology used is based on the hydrogeological and hydrochemical characterization of the area studied. A total of 16 piezometers were installed to monitor the amount and quality of water. Results obtained show a pH close to 8 and iron, manganese, zinc, and sulphate concentrations lower than 0.05 mg L−1, 0.05 mg L−1, 1.063 mg L−1, and 1305.5 mg L−1, respectively. The volume of the water stored in the lake amounts to 34 hm3. Measurements show that Fe, Mn, and Zn concentrations are below the limits acceptable for human consumption, according to the Spanish 0.2, 0.05, and 5.0 mg L−1 standards, respectively, while sulphate greatly exceeds the 250 mg L−1 limit accepted by the norm. Therefore, the water could be apt for human consumption after a treatment appropriate for decreasing the sulphate level by, for example, reverse osmosis, distillation, or ion exchange. Although industrial and energy uses are possible, the lake water could be utilized as a geothermal energy source. The management of the hydric resources generated when a mine is closed could improve the economic and environmental conditions of the zone, with all the benefits it brings about, thus allowing for compensating of the pumping cost that environmental protection entails, creating, at the same time, a new business opportunity for the company that owns the mine.
