“…As a result of the sedimentation applied for FP, FPA and FD, the amount of TSS decreased by 41, 88 and 97 % respectively. In FP supernatant, the amount of TSS was still greater than the permissible value and amounted to 43 mg/dm 3 . In order to remove such TSS, the washing process can be intensified, e.g.…”

“…Due to a different mechanism of filtration and washing, in vacuum filters, the method of sampling was also different. About 1 dm 3 of water was taken during emptying the filter tank, about 3 dm 3 The tested pollutant indicators were divided into basic (Fig. 2) and characteristic (Fig.…”

“…The search for modern, yet simple and inexpensive filtration methods is currently one of the basic directions of water and wastewater treatment technologies development. The conducted research concerns mainly new methods and materials for filters construction, modification of their operation methods, effective beds and an extension of the filtration cycle time without reducing its efficiency [3][4][5][6][7][8][9][10].…”

“…This is one of the reasons why new generation beds are becoming more and more popular, e.g. a bed containing silver with a disinfection effect [31], which allows to prevent the multiplication of microorganisms, a glass bed in which the negative surface charge allows additional removal of small organic impurities and positive ions from water, like iron or manganese [3,32], zeolite beds, diatomaceous or cellulose fibers that effectively remove fine suspended, colloidal and ammonium molecules from water [5,[8][9][10]33].…”

This paper presents the influence of the type of filtration beds, used in swimming pool water treatment systems, on the quality and the possibility of reuse of washings. The research covered 4 pool cycles with sand, sand and anthracite, glass and diatomaceous beds. The degree of contamination of washings was assessed on the basis of physical, chemical and bacteriological tests. The possibility of washings drainage into the natural environment was considered, and the results of the research were compared with the permissible values of pollution indicators for wastewater discharged to water or ground. A direct management of washings from the analysed filters proved impossible mainly due to the high content of TSS (total suspended solids) and free chlorine. Washings were subjected to sedimentation and then the supernatant was stirred intensively. As a result of these processes, the quality of washings was significantly improved. This allowed planning to supplement the pool water installations with systems for washings management.

“…This study also reported that the amount of CWG needed for filtration was 20% less than natural sand, showing greater economic benefit during handling, shipping, and disposal activities. Evans et al 136 studied the potential of CWG as a filter media to treat municipal potable water. It was observed that water quality obtained from CWG was similar to sand in terms of particle counts, turbidity, and metal content.…”

Each year, hundreds of thousands of tons of industrial wastes are being stockpiled, landfilled, and disposed of in storages occupying large areas of land that would otherwise be available for productive use. Recycling of such wastes is now becoming of urgent global interest due to an increasing population, the rise in anthropogenic activities, and the need for more efficient resource and waste management systems.Among many wastes, the generation of glass is dramatically increasing, particularly in the municipal, industrial, and construction sectors. In civil engineering, in general, crushed waste glass has been mainly investigated as a substitute for sand and finegrained aggregate in concrete production. In geotechnical engineering, in particular, the application of glass wastes is mainly limited to road pavements or as an additive to different soils for subgrade improvement. While glass wastes are relatively inert and potentially offer several opportunities for recycling as a substitute for diminishing and increasingly expensive sand supplies, their potential use yet remains relatively under-researched. This paper systematically reviews the current status of knowledge on the use of glass wastes in various civil engineering applications and discusses the suitability assessment of waste glass for use as a sustainable alternative to traditional civil engineering materials.

Crushed recycled glass as a filter medium and comparison with silica sandThe objective of this work was to evaluate crushed recycled glass as a medium for rapid filtration. In the first part of this work, physical and hydraulic characteristics of the glass medium were studied. In the second part, pilot scale inline filtration experiments were carried out using raw waters from three different water sources. Two physically identical filter columns were operated in parallel in all the experiments. One filter contained a silica sand medium that is widely used in Turkey, whereas the other filter contained crushed recycled glass. Experiments were repeated five times as follows: (i) Without the use of a coagulant, (ii-iii) with 5 mg/L and 10 mg/L of alum, and (iv-v) with 5 mg/L and 10 mg/L of ferric chloride. Turbidity, particle counts, and head losses were measured and compared as functions of time. The following were observed: (1) Provided that a coagulant was used, the filter containing crushed glass produced effluent turbidities and particle counts similar to those obtained with the sand filter. (2) The crushed glass medium generated both a smaller clean-bed head loss and smaller clogging head losses than those of the sand filter. It is concluded that crushed glass shows significant promise as an alternative to silica sand in rapid filtration.
