PURIFICATION OF OILY EMULSIONS WITH LEAF LITTER OF CHERRY AND ROWAN

, ,
 4-10 p.
Abstract
The paper presents the results of a study of the possibility of using leaf litter of cherries and Rowan, widely grown in Russia, for the extraction of oil of industrial grade I-20A from aqueous media. The sorption properties of cherry leaf litter and Rowan leaf litter were also studied. The bulk density, granulometric composition, humidity, pH of the aqueous extract and losses during the calcination of CLL and RLL were determined. High efficiency of purification of water-oil emulsions is established.

INVESTIGATION OF WATER ELECTRICAL ACTIVATOR WITH COAXIAL ARRANGEMENT OF ELECTRODES

, , , ,
 11-18 p.
Abstract
According to the World Health Organization, 80% of diseases are caused by poor quality of drinking water. Therefore, human life, animals, plant growth and development depend on the quality of water. Currently, when there is a continuous increase in the cost of medicines, fertilizers, pesticides, the problem of replacing the above drugs with cheaper substances is relevant. To solve this problem, it is proposed to use electro-activated water and aqueous solutions. On the basis of domestic and foreign experience, leading experts have developed methodological instructions for the widespread use and use of electro-activated water and aqueous solutions in engineering, agriculture, and medicine. For the production of electrochemically activated water and solutions, non-flowing and flow-through modular elements, as well as universal installations, were developed. Currently, a wide variety of electroactivators is offered. Analysis of the structures of these devices showed that flat metal plates are used as electrodes, therefore there are volumes of water that are exposed to uneven electrochemical effects. As a result, the specific energy consumption for obtaining activated water is significant. The purpose of the work is to reduce the specific energy consumption in the production of activated water and aqueous solutions. Coaxial arrangement of the electrodes leads to a reduction in energy consumption. Studies of the electroactivator of water with a coaxial arrangement of electrodes made it possible to establish the optimal ratio between the volumes of anolyte and catholyte and the time of electrolysis of water and an aqueous solution of sodium chloride. The results of the research can be used in the production of electroactivators for personal use as well as in industry and agriculture.

STUDYING THE PROCESS OF OIL-CONTAINING EMULSION PURIFICATION BY MEANS OF EXPERIMENT PLANNING METHOD

, , ,
 19-30 p.
Abstract
The process of oil-containing emulsion purification with chestnut tree waste (CTW) is considered. The factors influencing the process of purification with the application of a full factorial experiment are established. The mathematical model obtained under carrying out a full factorial experiment has the form of a linear equation. The results of the calculation are comparable with the results of the experiment. The data obtained allow conducting a process of water purification at optimal values of technological parameters.

ON THE CONCEPT OF DEVELOPING OPTIMIZED TECHNOLOGY OF OBTAINING MOLYBDATES AND TUNGSTATES OF d-ELEMENTS IN THE SOLID PHASES ON THE BASIS OF METABOLIC REACTIONS IN THE MUTUAL SYSTEMS MeSO4-Na2CO3-Mo(W)O3 WITH THEIR HEAT TREATMENT ((Me – d-ELEMENT)

,
 31-39 p.
Abstract
The paper presents the material devoted to the development of the concept of optimized technology for the production of molybdenum (tungstates) elements of the d-family (Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd and Ag) at a relatively low temperature, based on the model of a physico-chemical system, in which it is possible to form a thermally unstable intermediate phase – donor of high-defect oxide d-element, entering at the time of its formation into chemical interaction with thermally activated Mo(W)O3 with the formation of MeMo(W)O4.
In the process of solving the problem of finding the necessary to achieve the goal of the real prototypes of the chosen model of the physico-chemical system, taking into account the properties of reagents and products of their interaction, and in particular, the thermal instability of carbonates d-elements (their average decomposition temperature 3000C), it was concluded that they can be a system such as MeSO4-Na2CO3-Mo(W)O3, which was justified and confirmed in the laws of physico-chemical analysis, thermodynamics, chemical kinetics, theories of polarization of Nekrasov ions, acids and Lewis's grounds and confirmation in the experiment.

THE USE OF PEANUT PROCESSING WASTE AS A SORPTION MATERIAL

, , , ,
 40-49 p.
Abstract
The paper presents the results of the study of the possibility of using peanuts waste processing as a sorption material. The literature data on the use of numerous materials as sorbents are given. Physico-chemical and structural-morphological features of peanut shells were investigated. The object of the study was methylene blue dye as a widely known and used substance, and the sorption capacity for methylene blue is an important characteristic of industrial sorbents. The adsorption capacity of the material is calculated and the adsorption isotherm is constructed. The sorption capacity of the original peanut shell by methylene blue was 0.22 mmol/g.

DUST WASTE FROM CONCRETE PRODUCTS PLANTS AS AN ALTERNATIVE MATERIAL FOR WASTEWATER TREATMENT

,
 50-57 p.
Abstract
The paper presents the results of a study of factors affecting the efficiency of water treatment from heavy metals with dust from bag filters from Belgorod, ZhBI-4. The dynamics of the amount of dust formation of bag filters is given in the paper. The granulometric and phase composition of dust is investigated. A description of the processes occurring when adding dust to the aquatic medium is presented. The effect of dust mass on the pH of the aquatic medium is studied. It was established that this dust can be used as an adsorbent for the waste water treatment from heavy metal ions. High efficiency of wastewater treatment with dust of plant "ZhBI-4" is proved. It is shown that with an increase in the mass of the BFD additive to 0.5 g per 100 dm3, the purification efficiency smoothly rises to 99.9% with the mass of BFD 0.5 g for Sorig = 20 mg / dm3 and 95.3% for Sorig = 10 mg / dm3 The nature of the curve, which reflects the dependence of the PH of the medium on the mass of BFD, is similar to the shape of the curve, which reflects the dependence of the pH of the medium on the mass of the BFD, which emphasizes the effect of the pH of the aqueous medium on the process of formation of Cu (OH)2 precipitate. However, at the same time, it should be noted that the process of treatment from Cu2+ ions also takes place in the range of lower pH values, which exclude the possibility of formation of Cu(OH)2 precipitate. Therefore, treatment can occur due to the adsorption of Cu2 + ions and their hydrolysis products [CuOH] + on the surface of the BFD.
