The Subject

This 44-page booklet starts with a brief tutorial on the presence of bacteria in Florida lakes, and the aquatic environment in general, and then quickly turns to the subject that lake users are most interested in: possible sources of bacterial contamination and how to test for it. The discussion includes a comparison of the effectiveness of wastewater treatment plants versus septic tanks. Also, indicators used for detecting bacterial contamination are explained, along with basic laboratory methods. Lastly, an easy 4-step process is provided for tracking down bacterial contamination in a waterbody. Laboratory suppliers are listed at the end for individuals or groups interested in doing their own bacterial sampling. This document, CIR106, is the sixth of a series of information circulars dedicated to familiarizing citizens with the language and techniques used by those involved in water management.

Concrete Solution

Plastic pollution of the aquatic environment is a major concern considering the disastrous impact on the environment and on human beings. The significant and continuous increase in the production of plastics causes an enormous amount of plastic waste on the land entering the aquatic environment. Furthermore, wastewater treatment plants (WWTPs) are reported as the main source of microplastic and nanoplastic in the effluents, since they are not properly designed for this purpose. The application of advanced wastewater treatment technologies is mandatory to avoid effluent contamination by plastics. A concrete solution can be represented by membrane technologies as tertiary treatment of effluents in integrated systems for wastewater treatment, in particular, for the plastic particles with a smaller size (< 100 nm). In this review, a survey of the membrane processes applied in the plastic removal is analyzed and critically discussed. From the literature analysis, it was found that the removal of microplastic by membrane technology is still insufficient, and without the use of specially designed approaches, with the exception of membrane bioreactors (MBRs).

The purpose of the study was to evaluate, in a local approach, the state of supply of rural areas in a rural district with household wastewater management systems, with the focus on home wastewater treatment plants. The study covered the rural areas of the district of Olsztyn. The data, which were acquired from the Bank of Local Data, were processed through basic mathematical transformations and statistical measures. The structure and intensity indices were calculated per 1,000 residents. Large differences were found in the access to linear infrastructure and to individual systems of wastewater discharge. The results showed a constant increase in the number of home wastewater treatment plants and septic tanks due to the constant influx of people to villages lying around the town of Olsztyn. In contrast to studies conducted on a regional scale, no decrease in the number of septic tanks was observed correlated with the growing number of home wastewater treatment plants. A possible reason can be the specific environmental conditions and protection of inland waters, which limit possible locations of home wastewater treatment plants.

Micropollutant Removal

To achieve the Paris climate protection goals there is an urgent need for action in the energy sector. Innovative concepts in the fields of short-term flexibility, long-term energy storage and energy conversion are required to defossilize all sectors by 2040. Water management is already involved in this field with biogas production and power generation and partly with using flexibility options. However, further steps are possible. Additionally, from a water management perspective, the elimination of organic micropollutants (OMP) is increasingly important. In this feasibility study a concept is presented, reacting to energy surplus and deficits from the energy grid and thus providing the needed long-term storage in combination with the elimination of OMP in municipal wastewater treatment plants (WWTPs). The concept is based on the operation of an electrolyzer, driven by local power production on the plant (photovoltaic (PV), combined heat and power plant (CHP)-units) as well as renewable energy from the grid (to offer system service: automatic frequency restoration reserve (aFRR)), to produce hydrogen and oxygen. Hydrogen is fed into the local gas grid and oxygen used for micropollutant removal via upgrading it to ozone. The feasibility of such a concept was examined for the WWTP in Mainz (Germany). It has been shown that despite partially unfavorable boundary conditions concerning renewable surplus energy in the grid, implementing electrolysis operated with regenerative energy in combination with micropollutant removal using ozonation and activated carbon filter is a reasonable and sustainable option for both, the climate and water protection.

Hanoi, the capital of Vietnam, is experiencing rapid urbanisation coupled with high economic growth rates. This situation is both a challenge and an opportunity for the upgrading of existing technical infrastructures. Regarding wastewater treatment, the situation in Hanoi today is characterised by a lack of wastewater treatment plants, processing only a small fraction of the accumulating wastewater. Prevalent means of sanitation are septic tanks installed under buildings for the collection of domestic wastewaters, with overflowing liquids draining into the groundwater in an uncontrolled manner. This decentralised means of sanitation is therefore currently not able to clean domestic wastewaters in an effective way. This paper explores circumstances under which a semi-centralised approach can offer a sustainable solution to cope with these challenges in Hanoi. The approach has been designed to meet the challenges of fast growing urban areas around the world.

Abstract Chemical pollution poses a threat to the aquatic environment and to human health. Wastewater treatment plants are the last defensive line between the aquatic environment and emissions of pollutants. This study focuses on identification of most relevant hazardous substances in Estonian municipal wastewater and their fate in the treatment process. During this study, seasonal wastewater and sewage sludge samples were collected from nine municipal wastewater treatment plants and analyzed for 282 hazardous substances, including EU (n = 45) and Estonian (n = 31) priority substances. Results of this study show that several substances that are subject to international restrictions (e.g. Stockholm Convention) are still present in untreated sewage. Wastewater treatment systems that had a greater level of complexity (TEC &gt;5) were more successful in removing hazardous substances. Statistical analyses showed that removal efficiency of organic hazardous substances had significant (p-value &lt;0.05) linear correlation with removal efficiencies of chemical oxygen demand (COD) and total suspended solids (TSS), but a monotonic relationship with operators' competency. This study showed that operators' competency had a strong influence on the stability of the wastewater treatment efficiency and removal of organic hazardous substances.

&lt;p&gt;The increase in microplastics (MPs) research has aroused awareness about their presence and polluting potential in aquatic environments. Wastewater treatment plants (WWTPs) have been identified as one of the main paths for these pollutants to reach the environment. The present study is focussed in the WWTPs emplaced within the Guadalete-Barbate river basin. This geographical area comprises a total of 60 WWTPs treatment plants with an inhabitant equivalent (IE) above 250. Within these 60 wastewater treatment plants, there are 38 plants with conventional treatments and an estimated population of over 800,000. The high percentage of population that lives in this basin leads us to think about the quantity of microplastics that are dumped into the environment daily. Therefore, the aim of this research is to study the occurrence and identify the type of microplastics in these facilities, this information is important in order to design treatments that improve microplastics removal and avoid their entrance in the aquatic environment.&lt;/p&gt;
