Résumé :

Treating peat with nutrient-rich ash significantly increases the content of different nutrients in the substrate. Such ash treatment promotes the revegetation of abandoned extracted peatlands. The aim of this study is to analyze the effect of wood ash (WA15 = 15 t ha−1 and WA10 = 10 t ha−1), oil shale ash (OSA8 = 8 t ha−1), and a mixture of wood ash and oil shale ash (WA10 + OSA8) on the revegetation (vascular plants and bryophytes) of the Puhatu abandoned extracted peatland in NE Estonia. The following results were obtained: (1) The MRPP tests indicate that there are compositional differences

Résumé :

Acid mine drainage (AMD) is formed because rocks containing sulfide minerals, such as pyrite (FeS?), are exposed to oxygen and water. AMD treatment is generally carried out with lime, but this method is relatively expensive and unsustainable. Fly ash-bottom ash (FABA), a type of coal combustion waste can potentially replace lime in treating acid mine drainage (AMD). This study aimed to elucidate the potential use of FABA to neutralize pH of AMD. The method used was a floating FABA system using styrofoam with three treatments: floating FABA with dimensions (cm length x cm width x cm height) of

Résumé :

A pilot study on the feasibility of using high carbon wood ash to control composting odor emissions was conducted at a green material composting facility. The study's treatments consisted of adding 0%, 12.5%, and 25% high carbon wood ash by volume to green material compost feedstock in three separate windrows. The wood ash has properties similar to activated carbon with an active surface area of 105 square metres per gram on a dry weight basis. The odorant emission data suggest that the higher percentage wood ash treatment results in the most effective control of most compost odors and that wo

Résumé :

Spent activated carbon (SAC) usually exhibits a low specific surface area due to its high ash contents. In this study, pre-treatments, such as heat and acid treatments, were optimized to improve this feature. The heat pre-treatment did not reduce the ash content, nor did it increase the surface area. Because metallic ions adsorbed in SACs turn into ash upon the heat treatment. In the acid pre-treatment, the volatiles and fixed carbon were increased with decreasing ash contents. In this study, it was found that the surface area increase was correlated with the ratio between fixed carbon and ash

Résumé :

This article presents the results of fly ash from Circulating fluidized Bed Combustion (CFBC) and high temperature fly ash (defined in EN 450-1) with modified physical parameters by grinding. For this treatment was used the mechanical mill. In this case were used two fly ashes. The first sample was from Tisová power plant (CFBC fly ash) and the second one from Počerady power plant (high temperature fly ash). The modified samples were tested for the effect of grinding time on its grindability and granulometry. For testing of samples was used laser diffraction with particle size analyzer and the

Information is lacking regarding the influence of pre-fire microsite conditions on post-wildfire soil chemical properties. Following a 1994 wildfire along the eastern front of the Sierra Nevada range, California, high performance ion exchange chromatography was used to quantify anions and cations in aqueous soil extracts by plant microsite (Pinus jeffreyi subcanopy, Calocedrus decurrens subcanopy, Carer microptera meadow, Salix scouleriana subcanopy), by depth (ash or litter, mineral soil horizon 0-5 cm), and by treatment (unburned, burned). As compared to the unburned treatment, post-wildfire

Used Fenton reagent and fly ash combined process to treat dioctyl phthalate (DOP) simulated wastewater. Influences of pH, concentration of H2O2, Fe2+ concentration, fly ash dosage and other factors effect of COD were studied. The results showed that, under the synergies of the fly ash, Fenton reagent on the COD removal efficiency was better than Fenton reagent used alone. When the pH was 5, H2O2 concentration was 1.2 g/L, Fe2+ concentration was 1.0g/L, fly ash dosage was 4 g, and COD removal efficiency reached 83.21%.

Résumé :

Textile industries are the second largest water-consuming industries, next to agriculture. This research is aimed at investigating the utilization of fly ash as a low-cost adsorbent to treat hot wash liquor by employing one factor at a time. Contact time, effluent dosage, pH, mass of adsorbent, temperature, particle size, and agitation speed have been varied to find the optimum conditions for dye removal from hot wash liquor by fly ash. The results from the sorption process show that the maximum dye removal of 56.07% has been obtained at a time of 5 min, an effluent to water ratio of 9:1, pH o

Abstract We fertilized a Norway spruce (Picea abies (L.)

After five growing seasons, we remeasured the trees and took core samples. Current- and previous-year needles were sampled and analyzed for total nitrogen and carbon, low-molecular weight phenolics and condensed tannins. Annual volume increment and standing volume were significantly higher in the ASH + N treatment than in control plots after 5 years

The problem of Egyptian agricultural land is the production of Rice Husk Ash (RHA) with a huge amount and nothing made to reuse of it that made a lot of environmental problems. The average quantity of RHA produced in Egypt annually ~6 million ton and only 17% of it reused and the rest burnt causing a significant environmental problem. On the other hand, a lot of new water treatments plants (WTP) came into work producing many sludge quantities. The reuse of the sludge will reduce the burden on the environment.

Paddy plant chlorophyll is one of the determinants of plant growth and development, as photosynthesis plays a role in capturing light and transforming inorganic compounds into nutrients that plants need. The problem with the cultivation of paddy in the palm soil is the high saturation of the soil. There is a need for improvement in the ashes, ashes of palm powder, and empty palm cane ashes to lower the saturation. In addition, the application of jakaba LOF is necessary to boost the growth of milk dough crops, especially in the formation of chlorophyll. This research aims to determine the effec

Coal mining will form acid mine drainage in former open pit mines. If acid mine water enters community waters, it will cause disturbance to biota and decrease water quality. Sawahlunto is one of the cities in Indonesia that has a coal mining area located near a settlement. With the acid mine drainage, if it rains, the water will flow into the river where the water is used by the community. Part of the coal is used as fuel for the Sijantang Sawahlunto PLTU. The fuel also produces waste in the form of combustion ash known as fly ash and bottom ash (FABA). This study uses FABA to neutralize acid

The treatment and disposal of municipal solid waste incineration (MSWI) fly ash containing significant amounts of dissolvable salts and heavy metals is a seriously challenge. At present, the common treatment method for MSWI fly ash in Taiwan is the cement-based stabilization/solidification (S/S) process. In this work, an integrated hydrometallurgical process for the treatment of MSWI fly ash was evaluated. Ca was first recovered by combining water washing and ion exchange sequentially. Meanwhile, Zn in the water-washed fly ash was recovered by combining acid leaching and ion exchange sequentia

Abstract Water is a critical issue in the present world. Agricultural development, industrialization, and urbanization cause the drying up of most river basins in India and elsewhere further resulting in severe water shortages. In most cities in India, the estimated amount of sewage generated is around 40000 million liters per day (MLD). However, the sewage treatment capacity is only a mere 11786 MLD. To address this problem, several cost-effective and sustainable wastewater treatment methods are being researched. One such method is adsorption using Rice Husk Ash (RHA), an industrial by-produc
