“…Sewage from septic tanks is characterized by high pollutants concentration; in addition, it is rotten sewage. Because of this, it is necessary to determine the permissible share of the sewage coming from septic tanks in total amount of treated sewage [58][59][60]. In order to increase the reduction of sewage biogenic pollutants, it is suggested to consider the application of biofilters before the bioreactor with activated sludge in wastewater treatment plant facilities.…”

The aim of the present work was the modeling of the wastewater treatment plant operation work using Monte Carlo method and different random variables probability distributions modeling. The analysis includes the following pollutants indicators; BOD5 (Biochemical Oxygen Demand), CODCr (Chemical Oxygen Demand), Total Suspended Solids (SSt), Total Nitrogen (TN), and Total Phosphorus (TP). The Anderson–Darling (A–D) test was used for the assessment of theoretical and empirical distributions compatibility. The selection of the best-fitting statistical distributions was performed using peak-weighted root mean square (PWRMSE) parameter. Based on the performed calculations, it was stated that pollutants indicators in treated sewage were characterized by a significant variability. Obtained results indicate that the best-fitting pollutants indicators statistical distribution is Gauss Mixed Model (GMM) function. The results of the Monte Carlo simulation method confirmed that some problems related to the organic and biogenic pollutants reduction may be observed in the Wastewater Treatment Plant, in Jaworzno.

“…(Barwal and Chaudhary, 2014). It is difficult to clearly state whether the calculated retention times will determine the required reduction of pollutants in the bed with continuous flow (see : Table 1) (Ødegaard, 2006;Tilley, 2011;Kershaw, 2015, Bugajski et al, 2016a2016b). In extreme cases of water reservoir pollution -additional support of the process may be required by dispensing microorganisms with a certain degree of affinity for the substrate (Sitarek et al, 2017).…”

Aim of the study Adaptation of MBBR technology for the treatment of highly degraded waters in small water reservoirs. Investigation of the effectiveness of organic pollutants treatment in waters with highly polluted (or easily biodegradable) municipal sewage. Checking the effectiveness of nutrient removal during the process of cleaning this type of pollutants. Material and methods The study was conducted in laboratory conditions on a semi-technical scale. Diluted municipal sewage was treated in order to determine purification efficiency for each laboratory stand. The experiments were carried out in 4 research stands (volume of wastewater in each tank amounted to 1000 L), whereas each was equipped with a MBBR bioreactor with a moving bed (biofilm carriers). The physicochemical parameters of pH, redox, and oxygen concentration were examined, and laboratory analyses were performed to indicate changes in COD, BOD5, and selected forms of NH4 and PO4. On the basis of the obtained results, the effectiveness of the wastewater treatment was demonstrated, and the hydraulic parameters of the installation were modelled. Results and conclusions The results of experimental work indicate a significant effectiveness of the process of purifying and removing nutrients in MBBR installations. After designing a suitable floating platform, it will be possible to introduce such installations into degraded water reservoirs for their purification.

“…In rural areas, anthropogenic pressure on the surface water quality is related to plant and animal production. In addition, there is pollution from settlement areas resulting from the discharge of untreated or insufficiently treated wastewater, and from rainwater flushing various substances from properties, traffic areas, and waste dumps [7]. On the basis of the calculated impurity coefficient with the Burchard and Dubaniewicz formula (Wz = 1.85), it can be concluded that the surface waters running off the catchment were heavily polluted.…”

The anthropogenic problems in richly sculpted areas (mountain and submontane) are mainly related to agricultural activity, which shapes the quality of surface waters. This paper presents an analysis of the results of the hydrochemical tests carried out in the years 2007–2018 at check-control spots. The heavy metal pollution index (HPI < 100) indicated a low risk for aquatic organisms. The statistical calculations obtained by means of multivariate adaptive regression splines (MARS) designated that the hazard quotient (HQ) index can be combined with the electrical conductivity (EC) and total dissolved substances (TDS) parameters used in the assessment of water erosion. The HQ index showed that the concentration of individual heavy metals is lower than their value in the 0.5 percentile of the value. In subsequent studies, it should be assessed whether the size of arable land has an impact on the increased concentration of heavy metals in the surface water. We recommend small retention reservoirs as a potential management measure to improve the quality of the surface water at a regional scale. This study has great potential to mitigate the degradation processes related to the insufficient storage capacity, and to promote natural water retention.
