Water Sorption Purification from Ammonium Pollution

Abstract

Water sorption purification from ammonium pollution has been investigated. The sorption ability of natural clay sorbents has been characterized. The isotherms of ammonium ions adsorption by natural zeolites, palyhorskyties and glauconites were plotted. It was established that water purification from ammonium ions mainly corresponds to the model of surface diffusion at non-linear isotherm.

Cleaning of Effluents from Ions of Heavy Metals as Display of Environmentally Responsible Activity of Modern Businessman

“…Using the results of our research, we can propose a technological scheme of sewage treatment on the basis of a natural sorbent -bentonite -in full cycle (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Such a principle scheme for purifying the liquid waste of the galvanic line, or sewage after the tanning of leather production is given in Fig.…”

“…The mixture stands for a complete separation of the precipitate. The waste after reagent cleaning (7) is separated from the precipitate by means of a vacuum filter (10) and sent to the reactor with a stirrer (2), simultaneously conducting a control measurement of the concentrations of contaminated water after precipitation. Bentonite was preloaded in a reactor with a stirrer (2) in amount of 5 g / dm 3 of water.…”

“…The analysis of recent publications (Sabreen et al 2014, Malyovanyy et al 2013, Gaouar et al 2015 shows the expediency of applying modern adsorption methods by entrepreneurs for the purification of wastewater from pollutants using natural disperse minerals as adsorbents. Purification of aqueous solutions with the help of disperse sorbents testifies to the psychological readiness of business entities to adopt systemic environmental innovations and build their own model of environmentally-friendly business activity that meets the requirements of environmentally friendly and energy saving production on this basis.…”

Analysis of environmental safety of recreational territories of mountain ecosystems and development of technical measures for its stabilization

“…The general tendency in minimization of the impact of anthropogenic activity on NNPs is the use of renewable energy sources [24] to prevent pollution of the hydrosphere. The sources are natural sorbents [25], membrane methods [26] and biological natural purification methods [27].…”

Improving the Method for Producing Adsorbents from Agro-Industrial Wastes

“…Currently, most of the sorbents used for these purposes are expensive and have complex technologies of obtaining and regenerating [10]. Therefore, the creation of effective sorbents (involving agro-industrial wastes) and their practical application for adsorption purification technologies is one of the priority directions of the technical support of environmental safety 1 Kremenchuk Mykhailo Ostrohradskiy National University, 20, Pershotravneva St., 39600 Kremenchuk, Ukraine * sefira@mail.ru 2 Lviv Polytechnic National University, 12, S.Bandery St., 79013 Lviv, Ukraine ã Shmandiy V., Kharlamova O., Malovanyy M., Bezdeneznych L., Rigas T., 2020 [11,12]. The urgency of the research is stipulated by the necessity to find new ways to improve the quality of adsorbents, reduce the anthropogenic load on the water basin and follow the quality standards of hydro ecosystems [13].…”
