The standard groundwater treatment technology is a simple, non-chemical reagent based on aeration and filtration processes. This resulted in the formation of sludge (GWTS). Because one elements sustainable development possibility their reuse, that water plant operators are looking for new ways managing these sludges. At present, not all factors determining adsorptive capacity known. explanation why adsorption with similar structure chemical composition may differ significantly will allow...

Groundwater treatment residuals (GWTRs) are safe waste materials generated during drinking water treatment. GWTRs mainly deposited in landfills, but the preferred solution should be reused or utilized for some components. To ensure proper sludge management, it is important to provide quality, chemical composition, and texture characteristics of GWTRs. Therefore, this study, we aimed investigate compare features collected from four plants. were characterized by X-ray diffraction (XRD);...

Abstract Information concerning the use of non-ionic surfactants (NS) in household products is very scanty. Therefore, a qualitative determination NS raw sewage an alternative source information presence and manufacture NS. The aim this work was to identify (in Poznan Blonie, both Poland) treated Blonie) compare results with those obtained for river water (Warta Poznan, Poland). LC-MS/MS used purpose. 116 ethoxamers, being exclusively polydispersal alcohol ethoxylates (AE) containing alkyl...

The biofiltration process in the biologically activated carbon filters (BAC) is one of advanced methods water treatment.It enables efficient elimination dissolved organic matter and some inorganic pollutants.The production high-quality drinking requires an appropriate method filter work control based on biofilm growth assessment.The first aim study was to assess microbial development beds two BAC with use various methods.The second compare obtained results indicate which could support...

The purpose of pre-design technological investigations is to define the water treatment technology for a new or existing plant. investigation performed on model-scale equipment, making sure that results can be extrapolated scale. should allow determination unit process parameters and ensure desired outcome i.e. treated meeting applicable quality standards. Indirectly, also used as basis defining estimated scope investment, costs its execution future equipment operating costs. Technological...

Abstract The aim of the study was to select an appropriate technology for treatment groundwater with particular emphasis on effectiveness organic matter removal. technological research carried out a pilot scale 6 weeks. station supplied taken from two wells different physical and chemical composition mixtures waters. installation enabled configuration processes continuous water sampling past each device. following parameters were determined samples: temperature, pH, alkalinity, colour,...

The aim of this work is to determine the properties contact layers grain different type filter media in term their suitability for catalytical manganese oxidation and auto-activation removal from groundwater. following oxidative filtration materials were investigated: auto-activated silica sand taken full-scale filters (oxide coated media), Pyrolox – ore natural material Hydrolit artificially activated material. As a reference two not chemically active tested: clean chalcedonite....

Wastewater treatment plants (WWTPs) offer the possibility of recovering valuable substances produced by microorganisms, such as extracellular polymeric (EPSs). This study aimed to investigate generation and properties biopolymers microbial communities activated sludge from a large, full-scale WWTP. EPS composition in changed mostly during transition period winter spring. Higher temperatures favored higher protein (PN) concentrations PN/PSs (polysaccharides) ratio tightly-bound EPS,...

Natural waters contain organic substances that have a major impact on the quality of water, in particular its organoleptic properties. They can also change physical and chemical properties negative technological processes used during water treatment. There is no doubt contained natural to be removed treatment order achieve concentrations consistent with requirements concerning intended for human consumption. A very effective method compounds elimination from use biologically active filters...

Filtration through biologically active carbon (BAC) filters is an effective method of organic matter removal during drinking water treatment.In this study, the microbial community in initial period filters' operation, as well its role were investigated.Research was carried out a pilot scale on two BAC (Filter 1 and Filter 2) which distinguished by type inflowing water.It observed that number heterotrophic plate count bacteria total activity significantly higher samples collected from 2,...

The paper presents the results of analyzes granulometric composition suspended solids in backwash water from biological activated carbon (BAC) filters and its changes during sedimentation. Backwash samples were taken backwashing two pilot after different filtration time. It was found that regardless concentration collected water, particle sizes vs. their percentage volume contributions for all similar. Particle range 2–100 μm. However, two-hour sedimentation most proved to be effective...
