Suspended Particulates

In many situations, the purpose of water and effluent treatment by flocculation-sedimentation or flocculation-filtration is to remove the suspended particulates and not necessarily the “dissolved” macromolecular organics. Flocculation of above mentioned systems by “traditional” (low molecular mass, high charged) cationic polymers as primary flocculants is limited because of high flocculants requirement, caused by polymers chemical binding with anionic organic substances in liquid phase. Effects of matrix, molecular mass and ionic value of polymers on their interaction with SS and DOM were investigated in this research. Significant differences were discovered in interaction of the low molecular mass polymers and high molecular mass polymers with particulates in the presence of soluble organics.

AbstractThe empirical application of muds for therapeutic purposes is widely known. This is called pelotherapy and consists of the local or generalized application of a mixture of a solid phase and a liquid phase (peloid) for the recovery of arthro-rheumatic issues, bone-muscle traumatic damage and dermatological pathologies. During the time of mixing (maturation process) the mud is progressively colonized by thermophilic microorganisms that contribute to improvements in the peloid quality and endow the mud with organic substances. Several studies report diatoms as the main agent of thermal muds capable of producing anti-inflammatory sulphoglycolipid which renders the mud suitable for this use. The effect of the temperature is also considered important for therapeutic purposes.Recent studies assessed physical, chemical and technological properties of some peloids in use at spa centres. Some maturation surveys have also been performed in recent years. The need for quality criteria establishment and certification of clayey products intended to be used currently is evident, especially for peloids which have therapeutic action. Consequently, this study aims at the compilation and analysis of some characteristics of peloids from the literature in order to contribute to a major database that allows the establishment of regulations and quality criteria for suitable applications of peloids.

Poultry Processing

The main problem occurring during poultry and animal production is the management of waste generated in slaughterhouses and poultry processing plants. These wastes, due to the bacteriological threat and the difficulty in storage, adversely affect all elements of the environment and thus require quick neutralization. The prospective method of liquidation of this type of waste is thermohydrolysis in near-critical water. The aim of the work was to examine the decomposition of poultry waste, i.e. waste blood, soft tissues, chicken heads, feathers, subjected to the process of thermohydrolysis in near-critical water. The decomposition process was carried out at a pressure of 10 MPa in the temperature range of 120°C - 250°C and with a variable residence time in the reactor. Detailed analysis of the results allowed us to state that the longer the residence time in the reactor, the higher the content of soluble organic compounds in the liquid phase. The beneficial effect of applying the thermohydrolysis process on the increased reduction of organic substances present in the investigated wastes was also demonstrated.

Phase Oxidation

Plasma chemistry is part of the development of high technology that meets the modern requirements of greening and resource conservation. The study of physic-chemical laws and processes occurring in the zone of action of electric discharge plasma near the surface of a liquid is of high scientific and applied interest. In the study, developed and patented by a team of authors, plasma-chemical reactors were used, which implement the treatment of a liquid with both barrier and glow discharges near the surface of the liquid phase in a flow-through mode. Solutions of primary and secondary aliphatic alcohols were used as a model object of plasma-chemical treatment. As a result of the study, the mechanisms of liquid-phase oxidation of primary and secondary aliphatic alcohols during plasma-chemical treatment of water were proposed. The emission spectra of electric discharges at the gas-liquid interface in the presence of dissolved organic substances were obtained and analyzed. Spectral studies of electrodischarge plasma in the liquid-liquid zone confirmed the differing composition of the inorganic oxidation products of primary and secondary aliphatic alcohols. When deciphering the spectra of barrier and glow discharges, the characteristic emission bands of nitrogen N2, OH-radicals and nitric oxide, as well as lines of atomic hydrogen H and oxygen O were shown. In addition, the effect of the nature of the organic substances contained in the treated water on the characteristics of the electric discharge plasma was shown
