Opis:
This article presents the results of experimental studies pertaining to the suckling improvement of secondary clarifier in an aeration station in Almaty. According to the obtained research results, the work of secondary clarifiers was evaluated for the removal of suspended solids, concentration of returned sludge and sediment moisture. The technical specifications of aerations, secondary settling tanks and cesspool emptier in the aeration station of Almaty were defined. Additionally, it was shown that the use of the articulated sucker with movable scrapers can increase the efficiency of cleaning the bottom of the circular tanks. In this practical test, the proposed suckling radial settler in aeration station of Almaty during the year showed that the sucker reduces the costs for the installation and maintenance of cesspool emptier and has no damaging effects on the bottom of the sump.

Opis:
The household and industrial wastes that have been accumulated during the last 40–50 years organized and spontaneous landfills (garbage dumps) pollution of the natural water bodies near locations. As results of precipitation and solar irradiation, the drainage of water formation occurs; such waters are polluted with harmful and toxic ingredients. The known indices of pollution of industrial and surface waters as well as the technique for determining the class of danger posed by solid household wastes were analyzed. The application of this technique to liquid wastes is suggested, since the change of aggregate state must not restrict its application; on the contrary, a new useful unexpected result can emerge with this. A rather simple dimensionless index of toxicity was chosen on the basis of the following examples: composition of the drainage waters of a specific landfill, content of harmful ingredients in them, excess ratio of their maximum permissible concentration. Such an index takes into account the maximum permissible concentration of the harmful substance in the ground, as well as the fraction of the harmful ingredients in the total mass of the liquid waste. Using the dimensionless index of toxicity, the bar charts were drawn, from which the sequence of removal of harmful components from the liquid mixture can be determined, starting with the component with the least value of dimensionless index of toxicity which characterizes the most dangerous component.

Opis:
The study carried out an analysis of solid waste disposal and its implication for water quality in the Ugep Community, located in Yakurr’s Local Government Council of Cross River State, Nigeria. Findings revealed that there is a significant and adverse relationship between solid waste disposal methods and the quality of drinking water, along with domestic uses in the study area. Data was collected through the administration of 500 questionnaires, with family heads as points of primary contact. It was clear that the poor state of infrastructural development and the challenge of availability and access to requisite amenities, coupled with inefficient management of the few available resources, has further exposed inhabitants to health and welfare issues. Results indicate a significant relationship between the solid waste disposal (sanitation) method and water quality in the study area. Awareness creation on sanitary practices by health and related government agencies, as well as community members themselves, should be encouraged to participate, as it will ensure a sustainable and health-oriented waste disposal system, bearing in mind likely concerns for water quality. Contamination of water is more prevalent in stored water, especially at the point of usage, as compared to where water flows freely, and is used without being stored. If water quantity is massive, the challenge of low quality is easily resolved, as less sanitation problems would occur. Government and private organisations should implement and encourage economic empowerment initiatives, in order to improve the livelihoods of the residents of the community.
W niniejszym opracowaniu dokonano analizy sposobów odprowadzania odpadów stałych i ich wpływu na jakość wody w obszarze gminy Ugep w Yakurr Local Government Council dystryktu Cross River w Nigerii. Wyniki ujawniły, że na badanym obszarze zachodzi istotny i niekorzystny związek między metodami usuwania odpadów stałych, a jakością wody pitnej oraz użytku domowego. Dane zostały zebrane na podstawie 500 kwestionariuszy wypełnionych przez głowy rodzin. Jednoznacznie wykazano, że zły stan infrastruktury oraz wyzwania związane z dostępem do niezbędnych udogodnień w połączeniu z nieefektywnym zarządzaniem nielicznymi istniejącymi zasobami w zakresie urządzeń sanitarnych narażają mieszkańców na problemy zdrowotne i socjalne. Wyniki przeprowadzonych badań wskazują, że istnieje istotny związek między metodą unieszkodliwiania odpadów stałych (odkażaniem), a jakością wody dostępnej w obszarze prowadzonych badań. Warunkiem stworzenia zrównoważonego i służącego zdrowiu systemu usuwania odpadów, przy jednoczesnej trosce o jakość wody jest zachęcanie przez służby medyczne i odpowiednie agencje rządowe, a także samych członków społeczności do wspólnego zaangażowania w proces podnoszenia świadomości na temat praktyk sanitarnych. Poziom zanieczyszczenia wody magazynowanej, zwłaszcza w miejscu jej użytkowania, jest znacznie wyższy niż wody rzecznej, wykorzystywanej bezpośrednio. W przypadku dostępności dużych zasobów wody, problem jej niskiej jakości można łatwo rozwiązać, ponieważ wiąże się to z mniejszą liczbą problemów sanitarnych. Zarówno organizacje rządowe jak i prywatne powinny wdrażać i wspierać inicjatywy na rzecz podniesienia poziomu ekonomicznego mieszkańców tej społeczności.

Opis:
At Lawspet area in Puducherry, India, a unique situation of co-disposal of solid waste dumping and secondary wastewater disposal on land, prevails simultaneously within the same campus. So an attempt is made to assess the combined effect of this co-disposal on the environmental quality and pollution effects on groundwater quality with a view to correctly monitor the situation. Multivariate statistical analysis like hierarchical cluster analysis (HCA) and discriminant analysis (DA) were employed. HCA was performed on borewells, physiochemical parameters and seasons. Borewell clustering identified four clusters illustrating varying degree of groundwater contamination. In parameter clustering, two major clusters were formed indicating hardness and anthropogenic components. Temporal clustering identified three major clusters indicating pre-monsoon, monsoon and post-monsoon. Discriminant analysis revealed nine significant parameters which discriminate four clusters qualitatively affording 86% correct assignation to discriminate among the clusters. Also three major components viz. anthropogenic, hardness and geogenic responsible for groundwater quality in the study area were identified. Conclusively the investigation revealed that the direction of the contaminant transport is towards the southeast direction of the study area, where all the borewells (100%) are affected.

Opis:
Certain contaminants are termed as emerging (Contaminants of Emerging Concern, CEC) since all aspects of these pollutants are not known and their regulation is not ununiform across the nations. The CECs include many classes of compounds that are used in various industries, plant protection chemicals, personal care products and medicines. They accumulate in waterbodies, soils, organisms including humans. They cause deleterious effects on plant animal and human health. Therefore, alternative greener synthesis of these chemicals, sustainable economic methods of waste disposal, scaling up and circular methods using sludge for removing the contaminants are innovative methods that are pursued. There are several improvements in chemical waste treatments using electro-oxidation coupled with solar energy, high performing recycled granular activated charcoal derived from biomass are few advances in the field. Similarly, use of enzymes from microbes for waste removals is a widely used technique for bioremediation. The organisms are genetically engineered to remove hazardous chemicals, dyes, and metals. Novel technologies for mining economically the precious and rare earth elements from e-waste can improve circular economy. However, there is additional need for participation of various nations in working towards greener Earth. There should be pollution awareness in local communities that can work along with Government legislations.
