“…Among the methods described, regardless of the others, applications of microbiological biopreparations is main method (Mazur, 2020). Many scientific publications present the results of revitalization using this type of technology (Zakaria et al, 2010;Park et al, 2016;Sitarek et al, 2017;Dondajewska et al, 2019;Mazur, 2020;Sharip et al, 2020). Additional treatment-enhancing technologies are mainly based on aeration processes (Carr and Martin, 1978;Dixit et al, 2007;Dong et al, 2012;Chmielowski et al, 2019;Anber et al, 2020), or controlled planting of ecotones in zones of intensive nutrient supply to water (Vought et al, 1994;Fennessy and Cronk, 1997;Holland, 2012).…”

“…On the market, we can buy powdered or solid biopreparations (tablets) with freeze-dried forms of effective microorganisms spores. They are widely used all over the world for the active protection and treatment of surface waters (small and large water reservoirs) (Mazur, 2020;Sharip et al, 2020). The main advantage of their use is the ease of transport and dosing into water.…”

Aim of the study: The work aims to assess the possibility of the application of selected types of biological beds to support the revitalization processes of strongly degraded water reservoirs. Material and methods: The authors reviewed the literature on biological methods used in the treatment processes of various types of wastewater. Certain types of beds have been selected that show tolerance to temperature changes and significant changes in organic pollutant loads. The self-purification potential of water and the role of natural methods in the revitalization of water reservoirs were characterized. The characteristics of biological methods based on MBBR moving and fixed beds are presented. Results and conclusions: The possibility of application of selected types of MBBR moving and fixed beds in supporting the treatment of highly contaminated surface waters were assessed. Biotechnological methods based on liquid and solid biopreparations normally used in water revitalization were discussed. It has been shown that when biotechnological methods are not able to operate efficiently, it is very beneficial to start additional biological processes to improve the efficiency of the revitalization process.

“…Therefore, at the beginning of the 20th century, water quality started being taken more seriously [2]. Many studies have been tried to investigate mechanisms to improve water quality [7]- [10]. This, in turn, requires continuous monitoring of water quality to assess these methods and test their effectiveness, demonstrating the need for a low-cost and easy-to-use yet robust and scientifically proven method for determining water quality.…”

Monitoring water quality is an important challenge in both developed and developing countries. Remote sensing data can form a highly frequent dataset with acceptable spatial coverage that can be used to remotely monitor water quality. This paper presents a novel automated model for remotely monitoring water quality to address the problem of insufficient samples and save the time and cost of sample collection. The proposed model estimates both optical and non-optical water quality parameters via Sentinel-2A data. A bio-inspired hybrid model of a Binary Whale Optimization Algorithm (BWOA) and Artificial Neural Network (ANN) (BWOA-ANN) is applied to determine the relationship between extracted reflectance values from Sentinel-2A images and analyzed samples. The novelty of this model is to solve two main problems of remote water quality monitoring: poor applicability and low non-optical parameter estimation accuracy. For the first problem, a proposed fully automated model with band selection using the BWOA to automatically select the optimal features (Sentinel-2A bands) that are suitable for each water quality parameter. The second problem is addressed by automatically detecting the relationship between non-optical parameters, such as the total phosphorus, and optical parameters, such as chlorophyll-a. Three datasets with different locations, seasons, and parameters were selected to test the proposed BWOA-ANN. The experimental results demonstrated good regression with a mean R 2 value of 0.916 for optical parameters and 0.890 for non-optical parameters. The proposed model was found to outperform the ANN with an R 2 value higher by 40% and 52% for the optical and non-optical parameters, respectively.

“…It is important to further study how to increase the total phosphorus removal efficiency in winter, when it is cold. This article provides a good enlightenment that application of an effective microorganism product as a cyanobacterial control and water quality (Zati et al, 2020). The phosphate-solubilizing bacteria is the best choice for enhance consequent oxic uptakes of phosphorous.…”

Microbial phosphate removal from wastewater sewage is a promising and feasible technique that increases the ability of a sewage treatment system to remove phosphate from wastewater. Maintaining a healthy population of phosphate-solubilizing bacteria is the key premise of biological sewage treatment. Chitosan is used to remove dissolved phosphorus from the water column during wastewater treatment. The present study found that chitosan has another function in phosphorus removal, affecting the diversity and community composition of phosphate-solubilizing bacteria. We obtained 16S rRNA genetic data by using a shotgun metagenomic sequencing method. Data indicated that phosphate-solubilizing Pseudomonadaceae was the dominant bacteria population, after adding chitosan to the dynamic water treatment process. In chitosan-enhanced treatments, populations were 35.11% larger than the control group. Chitosan addition also caused some increases in the population sizes of Rhodocyclaceae, Bacillaceae, and Enterobacteriaceae, but the addition of chitosan had little effect on Hyphomicrobiaceae and Sphingomonadaceae in the activated sludge. Moreover, the Chao1 estimator, the abundance-based coverage estimator (ACE), and Shannon index all indicated a very high diversity of bacteria when chitosan was added. Finally, we determined that chitosan increased the activity of the enzymes phytase, dehydrogenase, and phosphatase, which enhance the degradation rate of phosphorus in the activated sludge of a D-A2O system. We suggest that chitosan plays an important role in dissolving organophosphorus during sewage treatment.
