Water quality and resource management in the dairy industry

Food industry is one of the most important and fastest growing sectors of economy in Poland. This sector is also characterized by high demand for the resources, particularly for water. Polish food industrial plants consumed 793xa0hm3 of water in 2014. Dairy branch had a combined 35% share of the above consumption. As shown by the data obtained from the Polish Central Statistical Office, the majority of dairy plants use its own source of water, so this branch is also important water producer in Poland. Water used for dairy industry should meet the requirements of at least drinking water quality, so the factories need to treat the water. This paper analyses the correlations between selected technical process, equipment profiles and water quality, and consumption in two types of dairy factories (DF). The first one DF-1 processes approx. 50,000xa0L of milk, and the second, DF-2 processes approx. 330,000xa0L of milk per day. The water taken from the wells needs to be pre-treated because of iron and manganese concentration and due to specific requirements in various industrial processes. As a result of this work, we have managed to propose technological solutions in the context of water consumption rationalization. The proposed solutions aim at improving water and wastewater management by reducing the amount of consumed water by industry.

Contaminated Soil Remediation: A Novel Cartographic Model for the Representation of Technical Maps

In the projects of remediation of contaminated site is necessary to produce several technical and cartographic maps that must describe the plan of characterization of the area, the level of the contamination, the sources and the possible techniques for its remediation. Generally, each project uses different ways for the representation of the variables causing an extraordinary effort by technicians of the Institutions that need to use these projects. In this context, one important challenge is the definition of a unifying language in order to communicate the main technical and specific indications in an effective way.

Control of quorum sensing signals and emerging contaminants in electrochemical membrane bioreactors

The present study investigated the influence of electric field on the removal of quorum sensing (QS) and emerging contaminants using an electrochemical membrane bioreactor (eMBR). A significant reduction of N-octanoyl-L-homoserine lactone signal molecules (∼76%) was achieved in the eMBR, with respect to the level observed in the conventional MBR as the control. Furthermore, the intermittent electric current supply (0.5u202fmA/cm2) was found to be effective for the removal of atrazine and estrone. The degradation of key pharmaceutical compounds, such as diclofenac, carbamazepine, and amoxicillin, was also possible, confirming the applicability of the eMBR system for removing the priority chemical compounds of public health concern.

Wastewater Treatment and Energy Production Through Electro Membrane Bioreactors

Membrane bioreactors (MBRs) are a well established and mature technology with many full-scale plants around the world treating municipal and industrial wastewater (Krzeminski et al. in J. Membr. Sci. 527:207–227, 2017).
