Runoff Quality

Highway runoff contains total suspended solids, hydrocarbons, oil and greases, chloride, and other contaminants that are transported in solution and particulate forms to adjacent floodplains, roadside swales, and retention/detention ponds. Oil and grit chambers represent a type of retention/detention unit used for removing heavy particulates and adsorbed hydrocarbon particulates. Storage/sediment units also represent a type of retention/detention unit used for controlling peak flow and removing suspended solids. The aim of this study is to evaluate the effect of traffic volume and site characteristics on highway runoff quality. The study also aims to evaluate the performance of retention/detention units that collect runoff from the Prague-Brno and Prague-Plzeň highways, Czech Republic. The results of this study indicate no definitive relationship between average daily traffic and concentration of runoff constituents, though the site characteristics have a strong relation to some constituents. The results also show that retention/detention units are effective in treating organic compounds.

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.

Runoff Quality

A water quality model POND for eutrophication and pollutant removal in urban stormwater runoff detention ponds has been developed. The numerical simulation model is a relatively simple, one-dimensional deterministic water quality model consisting of a set of differential equations. Included are processes describing the removal and accumulation of dissolved and particulate constituents as well as processes concerning the yearly cycle of phytoplankton growth and nutrient transformations. The input to the pond is based on runoff quality data and a historical rainfall record. The model has been used to simulate eutrophication and removal of phosphorus and heavy metals in an urban runoff detention pond. Especially the importance of the pond volume, i.e. the residence time of the runoff water in the pond, for pollutant removal and eutrophication has been analysed. Simulations were carried out based on measured runoff quality data and a 33 years of rainfall record. Dry, normal and wet years and summers were selected for the analysis.

The present paper reports pollutant removal efficiencies and reliability for a four-stage hybrid constructed wetland (HCW) consisting of the following sequence of subsurface (SS), vertical flow (VF) and horizontal flow (HF) beds: SSVF-SSHF-SSHF-SSVF. The experiments were carried out over a period of three years, with sampling done in each season: winter, spring, summer and autumn. Grab samples of wastewater collected from different stages of treatment were tested for total suspended solids (TSS), BOD5, COD, total nitrogen (TN) and total phosphorus (TP). The wetland was found to have a very high efficiency of removal of suspended solids and organics, with relatively little seasonal variability. The three-year average TSS removal efficiency was approximately 92.7%. The effectiveness of elimination of organic compounds was very high throughout the study period at 96.6% BOD5 and 95% COD. The effluent from the four-stage system had significantly lower contents of TN and TP compared to the wastewater discharged from the first two beds of this facility.

Investigations of hydraulic models of swirl, vortex and helical bend separators were accomplished at hydraulic laboratories of the CTU Prague from 1980. Significant separating efficiencies were observed, indicating a possible reduction of pollutant loads CSO and WWTP bypasses. The paper will present some practical applications of vortex flow separators in the Czech Republic, as well as proposed designs of helical bend CSO's. The first application has been made in the suburb of Prague Kbely. The projected vortex separators substitute the storage tanks and especially a pretreatment of stormwater is highlighted with regard to their applications. Nowadays a few of these structures are in operation (Kbely, Liberec, Brno, etc.) and others are just constructed (Vrchlabí, Hradec Králové) or designed (Chodov, Mseno, etc.). Finally a review of separation efficiencies of the vortex flow separators is presented, describing the efficiencies with regard to BOD5, COD and total suspended solids. All data are related to the hydraulic load of considered structures.

A field monitoring program was begun in 1991 to test the ability of grassed swales to remove pollutants from highway runoff. The two swales monitored had different slopes, traffic volumes, and vegetation heights, all of which can affect pollutant removal. One had a check dam, which proved to significantly influence pollutant removal. Also, the pollutant-removal ability of a short buffer strip was examined. Pollutants monitored included total suspended solids, chemical oxygen demand, total phosphorus, and total zinc. Manual and automatic sampling techniques were used to monitor runoff. The results suggest that properly designed short buffer strips and swales with check dams can remove pollutants from highway runoff.

This paper reviews the factors and criteria for the design of new and the retrofitting of existing dry detention ponds to enhance removal of total suspended solids (TSS) from stormwater. Detention time is discussed as the most important factor affecting TSS removal. Two-stage facilities and multi-level outlet design are important means of enhancing TSS removal in dry ponds. Two dry ponds within the city of Edmonton were selected to evaluate their TSS removal. The level of expected TSS removal is low owing to the relatively short detention times for both ponds. Methods for retrofitting the dry ponds to enhance TSS removal are discussed.Key words: dry pond, stormwater, TSS removal, detention time, retrofitting.

Abstract The article assesses the efficiency of pollutant removal at the sewage treatment plant in Goleniów after modernization of the technological system. The extension and modernization of the existing installation resulted from the need to adapt the treatment plant to accept larger loads of pollutants, improve the parameters of treated sewage discharged to the receiver, and the poor technical condition of the equipment. Before the modernization of the treatment plant, an increase in the loads of COD, BOD5, and periodic total suspended solids in raw sewage was observed as well as a reduction in the efficiency of removing pollutants from the sewage. The efficiency of removing pollutants after modernization was in the range of BOD5 - 94.4 ÷ 99.8%, COD - 89.3 ÷ 98.9%, total suspended solids TSS - 95.3 ÷ 99.7%, total nitrogen - 64.1 ÷ 95.4%, and total phosphorus - 75.4 ÷ 99.4%.

Solids Removal

Wastewater from car washes represents a potential problem for the sewer system due to its emulsified oils and suspended material. Treatment of wastewater discharged from four car washes was investigated by sedimentation and coagulation. The effect of the coagulants Servical P (aluminium hydroxychloride), Servican 50 (poly(diallyldimethylammonium chloride)), aluminium sulfate and ferric chloride was evaluated. The achieved removal using sedimentation was of 82%, 88% 73% and 51% for oils, total suspended solids, COD, and turbidity, respectively. In the treatment by coagulation we achieved average efficiencies nearly to 74% for COD removal, greater than 88% in the case of total suspended solids removal and 92% in the case of turbidity and except the performance of Servican 50 greater than 90% in oil removal. We concluded that the oil residual concentration and COD in the treated water allows pouring it in the sewer system complying with the limits of the Mexican rule NOM-002-ECOL-1996 and it is possible even its reuse, at least in the case of the chassis washing of cars.

This study evaluated the behavior of an anaerobic expanded granular sludge bed system using different methylparaben (MPB) concentrations. The assay was conducted for 268 days and was divided into seven stages of operation, which included the starting stage and subsequent stages where the MPB concentration was increased. The inoculum that was used was a mixture of anaerobic granular sludge with flocculent active sludge that contained 21.7 g/L of total suspended solids and 17.4 g/L of volatile suspended solids, resulting in an organic content of approximately 80%. The MPB removals after applying concentrations of 300 mg/L, 500 mg/L and 1,000 mg/L during the different stages and adding glucose to the influent were 94 ± 2.4%, 84 ± 5.8% and 88 ± 7.4%, respectively. For phases without glucose, the results were 97.4 ± 0.4%, 96 ± 1.6% and 98.2 ± 0.3%, respectively. The results showed a high pollutant removal and good progress in terms of the physical and biological characteristics of the granular biomass, which showed no change in the presence of the compound or a concentration increase.
