Opis:
The paper presents the current state of water supply and sewerage infrastructure and the need for its expanding in Radzyń district. The district is located in the northern part of Lublin Voivodeship in Poland. The following communes belong to Radzyń district: the municipal commune of Radzyń Podlaski and 7 rural communes: Borki, Czemierniki, Kąkolewnica, Komarówka Podlaska, Radzyń Podlaski, Ulan-Majorat, Wohyń. The data show that the water supply network in Radzyń district is well developed. The most significant percentage of the population using the water supply network has the rural commune of Radzyń Podlaski – 99.9%, while the smallest, commune Komarówka Podlaska – 54.5%. The survey showed that there was a very large disproportion between the development of the sewerage and water supply systems. The largest percentage of the population using the sewerage network has the municipal commune of Radzyń Podlaski – 99.7%. The smallest percentage of users of collective sewage disposal systems was recorded in the rural commune of Radzyń Podlaski (7.2%). The commune of UlanMajorat does not have a sewerage system. The survey conducted in 2016 shows that 8 collective wastewater treatment plants operated in Radzyń district at that time. The total capacity of the treatment plants is over 5,300 m3/d. In 2016, Radzyń district had about 1,000 household wastewater treatment plants. The presented data show that the condition of the sanitary infrastructure in rural communes of Radzyń district is unsatisfactory and requires the investment activities mainly aimed at expanding collective sewage disposal and treatment systems as well as developing a network of household wastewater treatment plants.

Opis:
Parameters characterizing the dewatering process of sewage sludge in small wastewater treatment plants (WWTPs) have been analyzed. Two municipal wastewater treatment plants of comparable capacity and similar technology of sewage treatment were selected to the analysis. Comparison of dewaterability of unprepared and conditioned sludge was made. During preliminary tests, the capillary suction time (CST) of sludge conditioned with cationic polyelectrolyte was determined. Next, for the optimal doses of selected polyelectrolyte, more detailed technological experiments were conducted such as vacuum filtration and susceptibility to the gravitational thickening. Tested sludge had very low susceptibility to thickening. The final volume of unprepared tested samples after 2 hour thickening was 977.0 cm3, while the initial volume of thickened sludge was 1000 cm3.The lowest value of final hydration for conditioned sludge was 64.0%.

Opis:
The aim of this paper was to present the current state and the need for development of the sanitary infrastructure in the communes of the Ryki District located in the Lublin Voivodeship. The Ryki District encompasses 1 urban Commune – Dęblin, 1 urban-rural Commune – Ryki and 4 rural communes: Kłoczew, Nowodwór, Stężyca and Ułęż. The paper is based on the data from the surveys conducted in all the afore-mentioned communes in 2016. In the whole district on average 71.3% of the population used the water supply network, while 42% of the inhabitants were able to discharge wastewater to the sewage system. Within the area of the Ryki District, 5 collective wastewater treatment plants with a capacity exceeding 5 m3/d functioned in 2016. The households which were not connected to the sewage network discharged wastewater mainly to non-return tanks. About 440 household sewage treatment plants were found in the surveyed communes. The overwhelming majority of such small objects in the discussed district were activated sludge systems (92%). The research carried out in 2016 proved a strong need to develop the current state of the sanitary infrastructure in the Ryki District. A particular emphasis should be placed on the wastewater management by connecting the inhabitants of urban areas to a joint sewage disposal system. Ecological awareness must be raised so as to encourage people to invest in household wastewater treatment plants, which should be used in the areas with scattered development.

The aim of this paper was to present the current state and the need for development of the sanitary infrastructure in the communes of the Bialski District located in the Lublin Voivodeship. The Bialski District encompasses 2 urban communes: Miedzyrzec Podlaski and Terespol and 17 rural communes: Biała Podlaska, Drelów, Janów Podlaski, Kodeń, Konstantynów, Leśna Podlaska, Łomazy, Międzyrzec Podlaski, Piszcząc, Rokitno, Rossosz, Sławatycze, Sosnówka, Terespol, Tuczna, Wisznice and Zalesie. The present paper uses the data from the surveys conducted in these communes in 2016. On average, 79.2% of the population used the water supply system in the surveyed communes, while 39.4% of the inhabitants had the possibility of discharging wastewater to the sewerage system. In the area of the communes, there were 20 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m3/d. The households which were not connected to the wastewater network, discharged wastewater mainly to non-return tanks. In the surveyed communes, there were 4437 household wastewater treatment plants. Most of them (above 80%) were the systems with infiltration drainage, which do not ensure high efficiency of pollutants removal and may even contribute to the degradation of the groundwater quality. In order to solve the existing problems of wastewater and water management occurring in the communes where the Bialski District is located, it is necessary to further develop collective wastewater systems and equip the areas characterized by dispersed housing with highly efficient household treatment plants, e.g. constructed wetlands.

wastewater reuse
Opis:
Once freshwater has been used for an economic or beneficial purpose, it is generally discarded as waste. In many countries, these wastewaters are discharged, either as untreated waste or as treated effluent, into natural watercourses, from which they are abstracted for further use after undergoing "self-purification" within the stream. Through this system of indirect reuse, wastewater may be reused up to a dozen times or more before being discharged to the sea. Such indirect reuse is common in the larger river systems of Latin America. However, more direct reuse is also possible: the technology to reclaim wastewaters as potable or process waters is a technically feasible option for agricultural and some industrial purposes (such as for cooling water or sanitary flushing), and is a largely experimental option for the supply of domestic water. Wastewater reuse for drinking raises public health, and possibly religious, concerns among consumers. The adoption of wastewater treatment and subsequent reuse as a means of supplying freshwater is also determined by economic factors. Human excreta and wastewater contains useful materials. These are water, organic carbon and nutrients and should be regarded as a resource. In their natural cycles, they are broken down by micro-organisms and become accessible to plants and animals, thus sustaining natural ecosystems. When improperly disposed, these substances can cause pollution. This is because the organic materials exert oxygen demand, and the nutrients promote algal growth in lakes, rivers and near-shore marine environments. Human excreta and wastewater also contain pathogens. Reuse of the wastes must ensure that public health is maintained. Planned reuse is the key to wastewater reuse. Planning for reuse ensures that public health and protection of the environment are taken into account. Reuse of treated wastewater for irrigation of crops, for example, will need to meet (i) standards for indicator pathogens, and (ii) plant requirement for water, nitrogen and phosphorus. WHO and others have developed standards for reuse of wastewater for various purposes. Further details of these standards can be found in the Regional Overviews in the Source Book, published by IWA and IETC. It must be pointed out, however, that requirements for water and nutrients are plant-specific and site-specific (dependent on soil type and climate), and information on these requirements need to be obtained from local information sources.

Opis:
The separable connections used in technological equipment of heat treatment furnaces (OTP) are described in this study. The equipment is used for the heat treatment of charges, i.e. for the thermal and thermo-chemical treatment of parts of machines and devices. OTP is used for the charge formation and its transport before, during and after heat treatment operations. Accessories of this type are usually compact structures composed of several or several dozen cast elements. The main components are grates and pillars, which form an outer contour of the OTP and also allow for the correct arrangement of heat-treated parts. To form a relatively rigid structure composed of the grates and pillars, it is necessary to join these components together. For this purpose, various types of separable connections are used, mainly of a cylindrical shape with threaded parts. The subject of this study is focused on the construction and operating conditions of typical OTP structures, as well as the methods of fastening the pillar in a grate, i.e. on the design of the bottom part of the pillar and the hole in the grate in which this pillar is embedded.

Opis:
The article presents an application of multi-criteria analysis for selection of the best treatment technology and the best technical solution to the running of a large and a small wastewater treatment plant. The calculations performed for two plant capacities and for various effluent standards are based on a compromise programming method. The effluent standards considered for the smaller plant are only BOD5, COD and TSS, while for the larger plant also nitrogen and phosphorus. For each plant’s capacity, three different treatment technologies are analyzed. The analyzed technologies included biofilters, continuous and cyclic activated sludge, rotating biological contactors and natural treatment methods. The selection of the best technology is done with a define set of sustainability criteria that can be easily modified and adjusted to specific local conditions. The proposed method can be used for selection of the best treatment technology and the most appropriate technical solution from a sustainability standpoint, at the stage of wastewater system planning and designing, as well as for evaluation of already operating plants.

Opis:
Various types of technological equipment individually designed for operation in pit and elevator heat treatment furnaces are described in this article. A common characteristic of these structures is that they are composed of several or several dozen thin-walled elements of various shapes and sizes, gravity cast in sand moulds from creep-resistant alloys (austenitic Cr-Ni/Ni-Cr cast steel and cast nickel alloys). The design of the castings requires the development of a manufacturing technology that can effectively use the principle of the simultaneous solidification of all components. Properly designed equipment should have minimum weight, maximum strength, and maximum loading capacity combined with adequate durability and reliability. Two designs of the equipment for the heat treatment of steel parts were presented. Both designs, as well as their individual components, were described in detail and illustrated. The main task of the equipment is to form the charge in the furnace and transport this charge both inside and outside the furnace. The first design is the design of an equipment for the heat treatment of large ring-shaped parts. The second design is the design of an equipment, whose structure can be modified using various repeatable components. As a result of these modifications, different variants of the equipment are obtained, allowing for the heat treatment of five different types of the shafts characterized by different shapes and sizes. The study is of an application nature. It is addressed to engineering and technical staff dealing with both the design and operation of heat treatment furnaces.

Opis:
A complex activated sludge model implemented in BioWin software has been implemented to assure its predictability and improve the effectiveness of biological wastewater treatment in the full-scale plant in Poland. The influence of temperature and sludge retention time (SRT) on the quality of the effluent was also studied. The calibration was successfully performed according to the Good Modelling Practice Unified (GMP) protocol. Five parameters at a steady state and ten under dynamic conditions were calibrated. It occurred that in the studied wastewater treatment plant SRT should be kept at the low level sufficient to sustain nitrification.

Opis:
The aerobic stabilization of excess sewage sludge using low frequency ultrasound (25kHz) was investigated. The mechanically thickened excess sludge was obtained from full-scale wastewater treatment plants. The samples of sewage sludge were prepared by dissolving drinking water to obtain initial total solid concentration of 1800 mg/dm3. Five samples were treated with ultrasound of different power per sample volume: 3,12; 6,25; 12,5; 25,0 and 50,0 Wh/l. The experiments show that ultrasonic pre-treatment with 50 Wh/dm3 power increases the digestion of organic matter in aerobic stabilization of sewage sludge.
Badano wpływ wstępnej obróbki osadu nadmiernego polem ultradźwiękowym o częstotliwości 25 kHz na przebieg procesu stabilizacji tlenowej. Osad do badań pochodził z rzeczywistego obiektu biologicznej oczyszczalni ścieków. Pobrano osad zagęszczony mechanicznie a następnie rozcieńczono go wodą wodociągową osiągając koncentrację suchej masy ok. 1800 mg/l. Pięć tak przygotowanych prób poddano nadźwiękawianiu aby zapewnić odpowiednie ilości włożonej energii w objętość próby: 3,12; 6,25; 12,5; 25,0 i 50,0 Wh/l. Badania wykazały znaczny wzrost mineralizacji masy organicznej osadu przy wstępnym preparowaniu polem ultradźwiękowym dla 50 Wh/I włożonej energii.

Opis:
The paper presents the results of research on the influence of the operational rinsing of a sewer system on the composition of raw sewage, the effectiveness of the operation of the mechanical part of a wastewater treatment plant and changes in the technological parameters of the biological reactor. The results of the research have shown an increase in sewage pollution during the rinsing of the sewer system. The value of the COD indicator increased from 799 to 1306 mg/dm3, BOD5 from 538 to 1044 mg/dm3, and total suspended solids from 259 to 1508 mg/dm3. The calculations indicate that an increase in the concentrations of pollution during the rinsing of the sewer system requires a high working efficiency of the mechanical part of the wastewater treatment plant. With a low efficiency the volume of the biological reactor can increase even by 30%.

During the past several years big changes have been observed in waste water disposal, noticeable particularly in the improvement of water protection and sewage treatment. An important element of waste water disposal still requiring improvement is a low development of sewage systems in rural and urban areas. The main problem is an increasing amount of sludge, high degree of sediment hydration and considerable ability to anaerobic decomposition, a lack of areas for managing sediments near big cities and deposits of sediments on storage areas. Selected issues of waste water disposal and sludge handling in the Mazovian Province against a background of waste water disposal and sludge handling in Poland were presented in the article.
W minionych kilkunastu latach obserwuje się duże zmiany w zakresie gospodarki ściekowej, widoczne szczególnie w poprawie ochrony wód i oczyszczania ścieków. Ważnym elementem gospodarki ściekowej, wymagającym nadal poprawy, jest mały stopień skanalizowania terenów podmiejskich i wiejskich. Zdecydowanie gorzej przestawia się stan gospodarki osadowej. Główne problemy w tym zakresie to zwiększająca się ilość osadów ściekowych, ich wysoki stopień uwodnienia oraz znaczne zagniwanie, brak terenów do ich zagospodarowania w pobliżu dużych miast, a także deponowanie na składowiskach. W artykule zaprezentowane wybrane zagadnienia gospodarki ściekowej i osadowej województwa mazowieckiego na tle gospodarki ściekowej i osadowej całej Polski.

Opis:
The objective of the study has been to evaluate the current state of household wastewater and sewage discharge facilities available in rural areas, with special attention paid to domestic wastewater treatment plants. Considerable differences have been determined in the access to water and sewage management infrastructure in individual provinces in total and within rural areas. In the countryside, especially where houses are scattered, domestic wastewater treatment plants seem to be a good solution. By being a form of lasting investment, they can generate ecological and economic benefits over a longer period of time. The analyses showed a constant growth in the number of domestic wastewater treatment facilities, coinciding with a decrease in the number of septic tanks.
