“…4(c)-(e) shows the microporous surface of tezontle particle covered with biofilm as a bacterial blanket. It is known that bacterial biofilms contain compounds with adhesive properties, generally heteropolysaccharides with high molecular weights, that allow not only adhesion to surfaces but also combination and stratification with other bacteria that do not have the ability to form biofilm [10,11,24].

“…In recent years, microbial consortia have been employed to degrade mixtures of pesticides The interaction of micro-organisms of different species permits the synergetic and efficient removal of contaminants, and the resulting products are integrated into catabolic processes for the generation of energy [25,2,36,37,24,29].…”

“…Despite the slow growth of the biomass and delayed kinetics of degradation a high rate of the process in the BAC-reactor was attained owing to the high concentration of the biomass (< 12 g/dm 3 ). Degradation ability constituted 8.7 kg of COD (m 3 /day) at the degradation degree of 70 % of the total quantity of organic matter in terms of COD [331].…”

The relative critical overview of indicators, which set norms to the drinking water and are used as background for regulatory instruments of the USA, the EU, the WHO, Ukraine and Russia, has been revealed. The analytical review of current problems in drinking water preparation technology at centralized drinking water treatment plants has been delivered. The role of natural organic compounds of natural origin in drinking water quality has been revealed. The application of different technological measures to prepare high quality drinking water has been analysed and explained. The influence of condition of water distribution system on the drinking water quality has been evaluated. It has been cited the examples of modern technological systems of drinking water treatment. A new concept of supply the population with a quality drinking water has been introduced. It is based on representation the need to consume adequate water by a person, which is genetically safe, comprises no man induced alloys, and is characterized by occurrence of such natural substances and microelements that are easiest to digest for a body from water. KeywordsThe quality of drinking water · International regulatory instruments · Centralized drinking water treatment plants · Modern water treatment technologies · Man induced alloys, natural microelements · A new concept of supply the population with a quality drinking water Ecological and Hygienic Classification of Centralized Drinking Water Supply SourcesIn the Ukraine, the goal of creating and adhering to adequate quality and safety standards for drinking water is guaranteed by law. Legal documents such as the Water Code of Ukraine [1] and the Law of Ukraine "On drinking water and drinking water supply" [2] were written to uphold this goal. Codex found in these documents details a range of specific tasks centered around ecological, sanitary, and hygienic contents namely:• A complex development of interrelated regulatory documents (standards and norms) for ensuring an ecological and sanitary-hygienic safety practice in the field of use and protection of water and water resources;

“…Wagner and Hempel (491) used a biofilm EL-ALR to study the biodegradation of naphthalene-2-sulfonate with Pseudomonas sp. Recently, Nicolella et al (492,493) used an IL-ALR to degrade a mixture of aromatic sulfonates with biofilms generated from industrial sewage sludges. The degradation rate observed in the ALR was higher than that in the activated sludge process installed at the industrial site producing the leachate.…”

ALRs are popular in modern bioprocess research and development and, in many cases, they have found industrial uses. The distinctive characteristics of ALRs are conferred by the fluid dynamics of the liquid‐gas or liquid gas‐solid mixtures: holdup, liquid velocity, and mixing in the riser, gas separator, and downcomer. Only a correct understanding of the interconnection of these regions can make possible the scale‐up of a laboratory device, to pilot or industrial size. Several correlations are available in the literature for the prediction of the fluid dynamic characteristics of the reactor and of the mass and heat transfer coefficients, and a selection is presented in this review. Significant progress has been made in the application of modern computational tools to the simulation and design of ALRs. In parallel, innovative and sophisticated methods have been applied to obtain a deeper insight into the mechanisms of fluid motion and the flow patterns in the reactor. However, no single research group has managed to cover all the variables over a wide range. The engineer confronting scale‐up or de novo design of an ALR must analyze the validity of the correlations and computation methods used for the calculations.
