“…According to Xu et al [66], the phosphorus sorption capacity of sands can reach up to 0.3 g/kg. The test results provided by these authors also indicate that during long-term exploitation of the beds, the sorption capacity of sands decreases, which also results in a decrease in phosphorus removal efficiency [8,64,65]. The domination of phosphorus sorption by the hole-filling mechanism may also explain the higher efficiency of removing this component during the post-vegetative period (November and February) (Figure 4).…”

“…Pollutant removal reliability values were assessed for the basic indicators of pollution (BOD 5 , COD, TSS, total nitrogen, and total phosphorus) using elements of Weibull's reliability theory. The Weibull distribution is a useful, general probability distribution, applicable in reliability tests and in assessment of the risk of exceeding the permissible values of pollution indicators in treated wastewater [8,[33][34][35]. It is characterized by the following probability density function:…”

“…The sorption properties of the sand used to fill the beds could have had a large impact on phosphorus elimination. Many researchers pointed out the importance of this material in phosphorus sorption processes in soil and plant beds, especially in the first years of operation of treatment plants [8,64,65]. According to Xu et al [66], the phosphorus sorption capacity of sands can reach up to 0.3 g/kg.…”

“…Among the solutions applied in household wastewater treatment plants, the most commonly used ones are drainage systems and systems using conventional methods of wastewater treatment-biological beds, activated sludge chambers, and facilities with a hybrid reactor [2]. However, due to the huge variability of hydraulic loads, pollution loads, and operating conditions, they do not guarantee high pollutant removal efficiencies [6][7][8]. An alternative to these solutions is constructed wetlands (CWs), which are characterized by simple operation, low operating costs, and resistance to changes in technological conditions [9][10][11][12][13][14].…”

In this paper, the pollutant removal efficiency and the reliability of a vertical and horizontal flow hybrid constructed wetland (CW) planted with common reed, manna grass, and Virginia mallow were analyzed. The wastewater treatment plant, located in south-eastern Poland, treated domestic sewage at an average flow rate of 2.5 m3/d. The tests were carried out during five years of its operation (2014–2018). The following parameters were measured: biochemical oxygen demand (BOD5), chemical oxygen demand (COD), total suspended solids, total nitrogen, and total phosphorus. The results showed that more than 95% of BOD5, COD, and total phosphorus was removed in the tested CW system. The average effectiveness of removal of total suspended solids and total nitrogen exceeded 86%. A reliability analysis performed using the Weibull probability model showed that the removal reliability in the tested CW was very high for BOD5, COD, total suspended solids, and total phosphorus (100%). The probability that the total nitrogen concentration in the treated effluents would reach the limit value (30 mg/L) established for effluents discharged from a treatment plant of less than 2000 PE (population equivalent) to standing waters was 94%. The values of all the pollution indicators in wastewater discharged to the receiver were significantly lower than the limit values required in Poland. The investigated hybrid CW system with common reed, manna grass, and Virginia mallow guaranteed stable low values of BOD5, COD, total suspended solids, and total phosphorus in the treated wastewater, which meant it was highly likely to be positively evaluated in case of an inspection.

“…One of the efforts to treat laundry wastewater is by using the constructed wetlands concept (Vymazal, 2014). Constructed wetlands have a few benefits which are the low operational costs, easy and feasible operation, contribution to the improvement of the landscape aesthetics, and providing habitat for many other organisms (Meng et al, 2014;Yeh et al, 2015;Zhang et al, 2014;Jóźwiakowski et al, 2018). Those benefits could justifz the application of constructed wetlands for treating laundry wastewater in populous areas.…”

The objective of this study was to determine the capacity, process, and kinetics of phosphorus (PO 4-P) nutrients pollutant removal in constructed wetlands with Equisetum hymale plants. This research was conducted by using a batch system constructed wetlands with detention time variation of 1-5 days and using gravel, sand, and soil as the media. The laundry wastewater used for this research was collected from commercial activity in Surabaya city. The results of this research showed that the removal efficiency of PO 4-P using the constructed wetlands with Equisetum hymale was between the range of 95.49-99.43%. The removal process was done by screening-adsorption, and the sedimentation mechanisms from the media, and the biosorpsion by the plants was shown by the increasing content of PO 4-P in soil and plants, which amounted to 14.80% and 9.23% respectively. The removal kinetics of PO 4-P was according to the second-order model with value of R 2 = 0.99.

Macrophytes are one of the biological elements for assessing the ecological status. Macrophyte communities were studied in six artificial (drainage canal and ditches) or modified watercourses (regulated rivers). In order to assess the ecological status of the watercourses, studies were carried out with the use of the Macrophyte Index for Rivers (MIR) proposed in the Water Framework Directive. Macrophyte communities were mainly represented by helophytes (12 species in total), and the highest percentage area cover (50–75% of the site) was observed for pleustophytes (Lemna spp.). Macrophytes communities were affected by the gradients of hydromorphological (canal modification, flow type, and shading) and parameters water quality (nutrients and water transparency). The relationships were highly species-specific. In accordance with the MIR values, the ecosystems were classified as having poor (drainage canal), moderate (regulated rivers), or good (drainage ditches) ecological status.
