Opis:: In this study, genotoxic potential of industrial waste water (IWW) samples was investigated using Allium cepa assay. The root tips were treated with different IWW samples (A, B and C) for 48 hours. The effects of IWW on cytological effects were determined. It was found that all IWW samples significantly increased the percentage of total abnormality. Mitotic chromosomal abnormalities such as irregular metaphase, stickiness, c-mitosis, micronucleus, vagrant chromosomes and bridges were determined. Furthermore, a significant reduction for the mitotic index that is indicative of cellular toxicity was observed in root tips cells, which were treated with IWW samples. A. cepa assay can be used as useful tool for the detection of genotoxic and cytotoxic potential of IWWs.

Opis:: Coagulant dosing control (CDC) is necessary to ensure stable treated water quality and to reduce chemical costs both in drinking and wastewater treatment plants. The rapid development in online sensors and equipment as well as control strategies has triggered a significant development in CDC. Software sensors, streaming current detectors, charge titration units, potential dispersion analyzers etc. are now successfully used. Despite the significant advancement in the introduction and use of these novel techniques, most plants still relay on simple CDC techniques like flow proportional dosing, leaving great opportunities to reduce the coagulant costs, sludge treatment costs while achieving better treatment efficiencies overall. The paper presents a novel concept to optimize coagulant dosing control in wastewater treatment plants, and an intention to develop a widely available solution using a Polish-Norwegian Research & Development venture.
Kontrola dozowania koagulantu (KDK) jest konieczna w celu zapewnienia stabilnej jakości wody, jak i obniżenia kosztów zarówno w stacjach uzdatniania wody, jak i w oczyszczalniach ścieków. Wraz z wielkim postępem w strategii i technologii tzw. czujników „online” obserwuje się również znaczny rozwój w zakresie KDK. Zdecydowanie zwiększa się zakres czujników procesorowych, czujników w ciągłym przepływie, zestawów miareczkujących do oznaczania ładunku, analizatorów despersji itp. W przeciwieństwie do znacznego zaawansowania we wprowadzaniu i zastosowaniu tych nowatorskich technik, większość oczyszczalni ciągle opiera się na prostych systemach KDK, typu ciągłego dozowania proporcjonalnego, nie uwzględniając wielkich możliwości redukcji kosztów zużycia koagulantu i obróbki osadów, które istotnie wpływają na efektywność pracy oczyszczalni. Praca niniejsza przedstawia nowatorską koncepcję optymalizowania dawki koagulantu w oczyszczalniach ścieków oraz możliwości rozszerzenia dostępności tych rozwiązań w Polsce poprzez Polsko-Norweską Instytucję Naukowo-Rozwojową.

Opis:: Quantifying soil quality is important for asses- sing soil management practices effects on spatial and temporal variability of soil quality at the field scale. We studied the pos- sibility of defining a simple and practical fuzzy soil quality index based on biological, chemical and physical indicators for assessing quality variations of soil irrigated with well water and treated urban wastewater during two experimental years. In this study 6 proper- ties considered as minimum data set were selected out of 18 soil properties as total data set using the principal component analysis. Treated urban wastewater use had greater impact on biological and chemical quality. The results showed that the studied minimum data set could be a suitable representative of total data set. Significant correlation between the fuzzy soil quality index and crop yield (R 2 = 0.72) indicated the index had high biological significance for studied area. Fuzzy soil quality index approach (R 2 = 0.99) could be effectively utilized as a tool leading to better understanding soil quality changes. This is a first trial of creation of a universal index of soil quality undertaken.

Opis:: Sludge treatment is one of the most difficult challenges for many industrial plants. In recent years, the use of ultrasound power has received considerable attention as one of the increasing tool for managing of this problem. Power ultrasound enhances chemical and physical changes in a liquid medium through the generation and subsequent destruction of cavitations bubbles. Therefore, the increased friction and stress in solution resultant with cleaning of the solid surfaces and dispersion of bonded/aggregated solid particles. In this study, the basic fundamentals of ultrasonic treatment and process variables were briefly overviewed. The study was also extended with preliminary analyses performed to determine its ability on the extraction of major and trace elements from Kırka Borax Concentrator tailings mainly boron as boric acid and Li as Li reach pregnant solution (PLS). Prior and after the sonification tests, physical, chemical and morphological analyses were carried out to determine the treatment performance. It was found that sonication leads the liberation of boron minerals from sludge and with the help of temperature they are dissolved and re-crystallized on clay substrate during cooling stage. The extraction test performed with these crystals revealed that Li-rich solution (that can be further use as source of lithium carbonate or lithium hydroxide production), and boric acid could be produced with easy and low cost beneficiation method.

Opis:: The technologies associated with the use of a membrane bioreactor (MBR) are becoming one of the dynamically developing directions in the wastewater disposal system. However, a certain part of the used design of membrane units are exposed to mechanical contamination, which significantly impairs their performance. This is especially noticeable when working at wastewater treatment plants, where the required degree of preliminary cleaning from solid mechanical particles and suspended solids is not provided. The purpose of the work was to improve the process of post-treatment of urban wastewater and protect the membrane element of the installation from clogging with coarse impurities and wear, with an overestimated concentration of suspended solids. The essence of the improved membrane technology of wastewater treatment consists in the preliminary capture of heavy and suspended particles with a size of more than 0.03 microns in a hydrocyclone, followed by water treatment in a chamber of a membrane bioreactor of modern design. The operating conditions of the membranes were determined by the operating modes and parameters of the bioreactor, in particular, by the degree of formation of colloidal compounds in it, which adversely affect the permeability. The density of the initial water varied within 1.059–1.078 g/cm3, and the content of solid particles was up to 0.3 mm. The activated sludge was filtered under vacuum on a Buchner funnel through a thin layer of cotton wool and gauze. During the tests, the indicators for capturing suspended solids were 5.0–9.0 mg/dm3, whereas, when working without a hydrocyclone, they were equal to 27–30 mg/dm3. The maximum performance of the hydrocyclone is provided at an inlet pressure of 225–300 kPa, and the pressure loss in the hydrocyclone chamber is 7.9–9.0 kPa. It was established that additional preparation of waste water for the post-treatment process using a hydrocyclone increases the cleaning capacity of membrane elements by reducing the load of accumulation of coarse impurities on the membrane surface.

Opis:: There are significant municipal concerns relating to the use of surfactants and enzymes in the process of wastewater treatment. Treatment plants use different techniques to remove impurities from water. As wastewater treatment plants use the latest technology to remove contaminants from water, there are high costs, and sometimes an enforcement of regulations is lax. Still, many municipalities across the country prohibit the use of surfactants and enzymes entering wastewater treatment because of the harmful effects of these products on the sewer lines and high damage costs. Surfactant compounds are organic. Their molecules include water-soluble and oil or an insoluble component. These molecular compounds seek the water surface and chemically reduce the boundaries between oil and water. When surfactants are in the water, they absorb into the soil and can cause injury to plants and organic organisms, but people find surfactants and enzymes useful in cleaning agents for emulsifying and dispersing oil and grease. Scientists have found that at least some surfactants are toxic to ecosystems, people and animals, but they have not been able predict far-reaching consequences. And now the most important question is how to solve this problem or how to reduce these negative effects. In this paper we tried to remove surfactants from waste water with an activated sludge system.
