“…The disc system captured about 3.5 kg MP from the secondary effluent of the WWTP, containing 4.6 kg MP, and only 1.1 kg MP was released into the environment. This finding supports other studies that have shown that a disc filter is suitable for removing MPs, as well as other pollutants [33,34], from treated wastewater.…”

In this paper, we evaluate the performance of a disc filter that retains microplastic (MP) particles from treated wastewater. A focal plane array-based Fourier transform infrared imaging technique enabled MP quantification and an in-house-built software (MPhunter) facilitated automatic analysis of the obtained infrared spectra. The disc filter retained 89.7% of particles, and 75.6% of their mass. This removal efficiency is comparable to removal rates reported by previous studies. However, the presence of an unexpectedly large number of MP particles whose size substantially exceeded the pore size of the disc filter suggests that particles could either bypass or pass through the filter mesh, somewhat diminishing the performance of the filter. The concentration of MPs in the effluent was 3 MP/L, corresponding to an estimated mass concentration of 0.31 µg/L. The annual MP discharge from the studied WWTP after the disc filter was estimated to be 1.1 kg in 2017. It was hence not a significant contributor to MP emissions in Denmark. Although the operation of the disc filter seems to have been disturbed, it nonetheless achieved a high MP removal rate. Therefore, we conclude that it is a suitable technology to decrease the concentration of discharged MPs in wastewater effluents.

“…For example, for issue number 5 which is related to pump, the breakdown of the equipment can be prohibited by scheduling more frequent cleaning, i.e. using a chemical clean with hypochlorite every three months [FYLYPCHUK et al 2017]. The following is Figure 3, which is about the stakeholders in problem solving.…”

The fostering and empowerment of water user associations (WUAs) has been regulated by the Minister of Agriculture since 2012. However, the implementation of this guideline varies. Some water user associations have achieved improvement, while some others have not. This study discusses how a WUA in the villages that use Bengawan Solo River water has successfully managed the irrigation. One of the factors leading to the success of this WUA is the stakeholder engagement in the agricultural irrigation management and farm business. This study was conducted from June 2016 to June 2017 by employing a qualitative approach. It aimed to identify and understand the stakeholder engagement in agricultural irrigation management by: 1) conducting an analysis on stakeholder power and interest indices, 2) mapping the positions, responsibilities, and obligations of stakeholders, and 3) identifying the stakeholder engagement in agricultural irrigation management. The research results are as follows: a) the analysis using Likert scale showed that the power index reached a value of 0.76, while the interest index reached a value of 0.78; b) the mapping of internal stakeholders, especially the responsibilities and obligations, has been regulated under the Articles of Incorporation of WUAs and obligations of external stakeholders, especially the government in making government regulations, irrigation infrastructure support, and flood prevention; c) cooperation of the stakeholders has an important role in the agricultural irrigation management and in solving the problems faced by WUAs.

“…In parallel with the construction of the drinking water network, the sewerage network and wastewater treatment plants were not established in many countries around the world, therefore municipal wastewater from households is stored in various installations without insulation in the yard of households (cesspits, soakaways, septic tanks) became a widespread practice [1][2][3][4][5]. Wastewater flowing out of these point sources resulted in a sharp degradation of the groundwater supply in the municipalities [6][7][8][9].…”

In the present study, the impact of the construction of the sewerage network (2014) on groundwater quality was studied on the example of a middle-sized settlement in the Great Hungarian Plain and changes in water quality were assessed using GIS and multivariate statistical analysis. As a result of the pollution that has been going on for decades, the groundwater supply of the municipality has become heavily polluted. In the period before sewerage (2011–2013), clear spatial differences were shown in the degree of contamination in the area of the settlement: the degree of contamination increased in the direction of local groundwater flow. Based on our results, the construction of the sewerage network resulted in marked changes in the quality of groundwater wells. Our studies showed a clear decrease in the concentrations of inorganic pollutants (NH4+, NO2−, NO3−, PO43−). In the fifth year of the post-sewerage period (2019), the clear spatial difference between wells was eliminated. We have observed a strong descent (1.5 to 2 m) in groundwater levels in the post-sewerage period, the reason for that is clearly due to that wastewater outflow was eliminated. On this basis, it can be declared that the purification processes in the area have started, but at the same time, our results show that pollutants entering environment undergo a number of transformations and remain in the system for a long time.
