Opis:: The article presents the results of the study on the process of copper electroevolution from the regeneration solutions in one- and two-chamber electrolyzers at different concentrations of sulfuric acid and the solutions of copper chlorides at different concentrations of hydrochloric acid – in a three-chamber electrolyzer. The conditions of electrochemical recovery of heavy metals from acidic and saline solutions were determined. It was shown that the most effective recovery of heavy metal cations from hydrochloric acid solutions occurs in three-chamber electrolyzers. On the basis of the results obtained, a technological scheme of a local plant for treatment of washing water of galvanic industries was proposed.

Opis:: The processes of desalination of weakly mineralized waters using a reverse osmosis membrane were studied. The operational efficiency of membranes is limited mainly by membrane contamination. It was shown that the preliminary mechanical water purification helps to increase the productivity and selectivity of the membrane. One of the main causes of membrane contamination is the formation of carbonate deposits on their surface. One way to prevent membrane contamination is to dose antiscalants. It was established that the use of hydrolyzed polyacrylonitrile (HPAN) and hydrolyzed polyacrylamide (HPAA) as a stabilizer of scale formation is effective for concentrates of reverse osmosis desalination of water.

Opis:: A method to improve the quality of purified water, reduce the cost of reagents for the regeneration of resin and create low-waste processes have been developed. This paper presents the results of ion exchange separation of sulfates and nitrates using AV-17-8 anion exchange resin in NO3 form. The efficiency of anion separation on the highly basic anion exchange resin AV-17-8 depends on the magnitude and ratio of their concentrations in water. Separation on the AV-17-8 anion exchange resin has been shown to be effective at concentrations of sulfates up to 800 mg/dm3 and nitrates up to 100 mg/dm3. Conditions for regeneration of 10% NaNO3 anion exchange resin were determined. Reagent precipitation of sulfates from the used regeneration solution in the form of calcium sulfate was carried out. Calcium sulfate precipitate can be used in the manufacturing of building materials. The regeneration solution is suitable for reuse. The developed results will allow to introduce low-waste desalination technology of highly mineralized waters.
Celem pracy było opracowano metody poprawy jakości oczyszczonej wody, obniżenia kosztów odczynników do regeneracji żywicy i stworzenia procesów niskoodpadowych. W pracy przedstawiono wyniki rozdziału jonowymiennego siarczanów i azotanów z użyciem żywicy anionowymiennej AB-17-8 w postaci NO3. Skuteczność separacji anionów na wysoce zasadowej żywicy anionowymiennej AB-17-8 zależy od wielkości i stosunku ich stężeń w wodzie. Wykazano, że rozdział na żywicy anionowymiennej AB-17-8 jest skuteczny przy stężeniach siarczanów do 800 mg/dm3 i azotanów do 100 mg/dm3. Określono warunki regeneracji 10% żywicy anionowymiennej NaNO3. Przeprowadzono odczynnikowe wytrącanie siarczanów z zużytego roztworu regeneracyjnego w postaci siarczanu wapnia. Osad siarczanu wapnia może być wykorzystany do produkcji materiałów budowlanych. Roztwór do regeneracji nadaje się do ponownego użycia. Opracowane wyniki pozwolą na wprowadzenie niskoodpadowej technologii odsalania wód wysokozmineralizowanych.

Opis:: Among all known inorganic pollutants of wastewater and natural water that adversely affect water bodies, different living organisms and human beings, iron compounds are the most common. Before discharging the wastewater into water bodies, it is important to remove iron ions from wastewater. The application of capillary materials in water and wastewater treatment is a promising direction of ecology and technology. The capillary properties of materials allow the development of quite simple, autonomous, highly efficient and energy-saving systems for water purification. The aim of the present paper was the investigation of the influence of the basic conditions of the filtration process with the application of capillary materia on the efficiency of iron ions removal. The initial concentration of the model solution, pH and temperature of the filtration process, as well as the contact area of the liquid phase with oxygen of the air were studied. The proposed method is appropriate for the treatment of water in the concentration range from 5 to 10 mg/dm3 with an optimum pH in the range of 4–7. The experimental data showed high efficiency of capillary materials application, providing sufficient removal of iron ions from low concentrated solutions, compared to the traditional method of precipitation. The main advantage of the capillary materials is the simplicity of their application, quite high degree of purification and there no need to consume electricity or additional reagents, which allows creating autonomous water treatment facilities and plants.

Opis:: The necessity of development of technical solutions that will allow to reduce carbon monoxide emissions of flue gases of industrial productions is substantiated. It is shown that the most rational design solution to the problem of carbon monoxide pollution during the firing of electrode blanks is the use of aerated concrete blocks with a catalyst, which can be quickly and conveniently located directly on the carbon material of the “green” electrodes pouring in the subfloor space of the firing furnaces. Modified by oxides of Mn4+, Fe2+, Fe3+, Cu2+, Cr3+ -catalysts based on aerated concrete were obtained. It is shown that in an empty reactor in the temperature range 200–400 °С the degree of conversion of carbon monoxide in the absence of a catalyst is zero. It is established that on the investigated catalysts based on aerated concrete 100% oxidation of carbon monoxide is achieved at a temperature of 390 °C in the case of using a mixture of catalyst powders 30% CuO + 70% MnO2, 40% CuO + 60% MnO2, 50% Fe (FexCr1-x) 2O4 + 50% MnO2; 50% Fe3O4 + 50 % MnO2. It is determined that the addition of ferrite catalyst powder in aerated concrete in a mixture or without manganese dioxide does not critically affect the mechanical properties of the products.

Opis:: The problem of utilizing plant wastes of the agro-industrial complex is equally important and urgent. In this regard, it is advisable to develop a complex technology of plant waste application to solve the ecological problems of environmental pollution with heavy metals. Modification of walnuts shells with orthophosphoric acid has proven to be a promising process for obtaining the biosorbents with the efficient sorption properties. It was found out that the increase in the concentration of inorganic acid in modification time promotes the improvement in sorption capacity. Such biosorbents can be used in low-waste water demineralization systems. The utilization of waste biosorbents through the use in the composition of building materials is effective from an economic point of view. It was shown that the biosorbent acts as a fine additive; the increase in normal density and acceleration in hardening time takes place. At the same time, the compressive strength of the cement with the application of biosorbents decreases slightly. The results show that the modified walnuts shells have a slightly adverse effect on the hardening time of cement.

Opis:: Development of new and modification of existing chemicals, which act not only as binders, but also provide increased retention of fiber and other pulp components on the paper machine grid, accelerate pulp dehydration, and provide special properties (moisture resistance, heat resistance, improvement of other technical characteristics of paper and cardboard) of paper and cardboard, is an important and urgent task of chemical technology and ecology. This paper presents results of the corn starch modification with epoxypropyltriethanolammonium chloride, hexamethylolmelamine and hexamethylenetetramine. Modified starches provide the necessary strength indicators of cardboard from waste paper and low turbidity of wastewater. The obtained starches can be used in mills that use low-quality waste paper for the production of cardboard and paper products with the aim of saving fiber, reducing wastewater pollution and as a result reducing the negative impact on the environment.

Opis:: As a rule, nitrates are present in all natural water bodies. Their increased concentrations are connected with the discharge of insufficiently treated wastewater from industrial and communal enterprises, agricultural and livestock complexes. Recent scientific publications concerning treatment methods for nitrates removal from natural water and wastewater were analyzed in order to create effective and low-waste technology for obtaining high quality water. It has been established that the ion exchange method is quite effective for removing nitrates from water. In the paper, the processes of ion exchange removal of nitrates from water on low-axis anionite in DOWEX Marathon WBA in Сl- form were investigated. During the sorption of nitrates with a concentration of 186, 205, 223 and 2200 mg/dm3, it was established that the full exchangeable dynamic capacity was 1.075, 1.103, and 1.195, 1.698 g-eq/dm3, respectively. To regenerate anionite, solutions of ammonia as well as potassium chloride, ammonium chloride and potassium carbonate were used in this work. The choice of potassium and ammonium compounds is due to the prospect of further use of regeneration solutions for the production of liquid fertilizers.

Opis:: The research is related to solving the problem of rational use of materials and to the creation of resource-saving technologies for the protection of the environment from pollution. Sorption technologies are quite effective in wastewater treatment, but most sorbents are quite expensive, and their regeneration raises the question of recycling of spent solutions. The cheapness and availability of raw material base of biosorbents makes these technologies attractive for wastewater treatment. The research is aimed at investigation of the ways to effectively utilize the spent sorbents, which are obtained after water purification, in the production of building materials. The obtained results allow creating a complex low-waste technology of water demineralization and purification from heavy metal ions.
