Application of adsorbents based on organo-zeolites has certain advantages over conventional methods applied in food industry wastewater treatment process. The case study presented in this paper examines the possibilities and effects of treatment of dairy industry wastewater by using adsorbents based on organo-zeolites. The obtained results indicate favorable filtration properties of organo-zeolite, their high level of adsorption of organic matter and nitrate nitrogen in the analyzed wastewater. This paper concludes with recommendations of optimal technical and technological parameters for the application of these filters in practice.

This paper presents a model of an intelligent energy harvesting system from microbial fuel cells (MFCs) in the wastewater treatment process. The model consists of two direct current (DC/DC) converters connected in a cascade. One DC/DC converter is used to capture energy from MFC and store it in a supercapacitor. The other DC/DC converter is responsible for increasing the low output voltage to a higher voltage level. In the paper, the MFC is modeled by a DC voltage source instead of a real MFC that contains wastewater inside it. The experimental results demonstrate that the model of an intelligent energy harvesting system can increase the low output voltage of MFC up to 3.3 V and achieve intermittent output power at a high level that can use in practice.

New Model

This paper describes a new anaerobic digestion model for wastewater treatment systems (MantisAD). The model has been developed specifically for plant-wide wastewater treatment modelling. That is, rather than modelling nitrogen as a series of fractions of other carbonaceous state variables, this new model includes six dedicated nitrogen state variables. This structure makes this new anaerobic model easier to incorporate into plant-wide models by simplifying the aerobic/anaerobic model interfaces. The model is complete and initial success with the model has been achieved. A comprehensive description of the model including a Petersen Matrix representation of the model is included as is a case study in which the model is applied to full-scale anaerobic digesters.

Abstract The problem of specific malodours odorants, emitted from the territory of wastewater and sludge treatment facilities is set in the article. This article presents a critical review concerning the reasons of odorants formation during wastewater treatment, their influence on human health and ways of wastewater and sludge deodorization. Review is presented by 52 resources of Russian, Chinese, Italian, Greek, Indian, American and other researches from 2000 to 2021 years. According to the review the main sources of odours emission are units of mechanical treatment, sludge thickening and sludge digestion. The main odorants are volatile organic compounds (VOCs), hydrogen sulphide, ammonia, particulate matters and greenhouse gases (carbon dioxide, methane, nitrogen oxide). Based on the article, there are two ways of emission controlling: controlling the technological parameters of wastewater treatment process or gases treatment at specific facilities (adsorbers, biofilters, bioscrubbers, chemical scrubbers).
