Cross Compliance

Several studies have described the effectiveness of vegetated buffer strips, interposed between the cultivated areas and water bodies, in removal of suspended solids and other pollutants such as Glyphosate conveyed through surface runoff. This monitoring study has quantified the effects of a 5-metre wide herbaceous buffer zone, adjacent to a vineyard, built according to the Standard 5.2 of Cross-compliance (M.D. 27417). The amount of runoff generated was 3.9% of the total annual rainfall, with negligible differences in terms of volume after flowing through the buffer zone. The effectiveness of the buffer zone in suspended solids removal was, in terms of mass balance, of 45.5%. The glyphosate outputs from the vineyard, unlike in other experiences, were negligible and therefore it was not possible to evaluate the efficiency of the buffer zone in removing it. This is due to the low rainfall occurred in the period following distribution that has favoured <em>in situ</em> degradation of Glyphosate.

At the outlet of the Vermicelli catchment—a peri-urban area located in the campus of University of Calabria (Cosenza, Southern Italy)—a sedimentation tank is located, aiming at collecting the basin surface runoff and improve its quality. First, experimental results of the treatment effects are here presented and analyzed. In addition, a monitoring campaign was conducted in order to characterize the particles transported by surface runoff and to determine the treatment efficiency of the tank. The analysis showed the presence of a pollutant load in the surface runoff of the Vermicelli basin and provided information on its particle-size distribution (PSD). Results were considered in terms of the treatment efficiency of the sedimentation tank, showing a good overall removal efficiency value, together with a high variability of the removal sedimentation efficiency. This variability is mainly due to the different grain size of the suspended solids and the characteristics of the rainfall event.

Surface runoff from urban area is a potential source of pollution of water bodies. Characteristics of rainfall runoff in some cities of Russia and foreign countries are given in the article. Traditional wastewater treatment facilities include the mechanical removal of large items, debris and leaves; sand removal; water clarification in accumulative clarifying tanks; chemical dosing, contact filtration and deep purification in sorption filters. Four technological schemes were analyzed. Conceptual difference of the schemes is using a new construction of accumulative clarifying tanks and different types of filters with inert floating polysterene load (CFPZ-1, CFPZ (CS), AFPZ-4). The investigation results of pilot plant that simulates the purification process of surface runoff in clarifying, sorption and I and II step cartridge filters are given in the article. During the investigation period the water entering the pilot plant had the concentration of suspended solids – 81-180 mg/L, petroleum products – 2-8 mg/L, COD – 48-97 mg/L. Analysis of the dynamic of changes in the concentration of suspended solids and petroleum products in previously treated in accumulative clarifying tank water during the filter cycle at each step showed that purification efficiency in polystyrene load layer depends on the type and dose of flocculant, filter rate and duration of filtration. The investigation results were used for the development of recommendations for the intensification of operation of industrial filters and improving technological reliability of surface runoff treatment facilities.

Поверхностный сток с территорий крупных мегаполисов интенсивно загрязняется. Особую роль в загрязнении играют автопарковки, на территории которых формируются сточные воды с высокими концентрациями нефтепродуктов и взвешенных веществ. Целью работы была тестовая многосезонная эксплуатация фильтра-сепаратора ФОПС®-С при очистке поверхностного стока, поступающего в систему канализации с территории автопарковки. В ходе наблюдений установлено, что на протяжении 21 месяца испытаний фильтр ФОПС®-С обеспечивал эффективность очистки сильнозагрязненного поверхностного стока от взвешенных веществ 82–99% и нефтепродуктов 55–76% (при их максимальной концентрации в стоке 3000 и 10,5 мг/дм3 соответственно). Снижения эффективности очистки в течение 21 месяца не наблюдалось, в том числе в периоды отрицательных температур (два сезона). За время испытаний из фильтра ФОПС®-С дважды производилась гидровыгрузка задержанных загрязнений: взвешенных веществ (~ 130 кг) и нефтепродуктов (~ 2,1 дм3). Surface runoff from large metropolitan areas is heavily polluted. Car parking areas are of overriding concern in pollution since the surface runoff generated on them contains high concentrations of oil products and suspended solids. The aim of the project was multi-season test operation of a FOPS®-S filter-separator for the purification of the surface runoff disposed into the sewer system from the parking area. In the course of observations, it was found that over 21 months of testing, the FOPS®-S filter provided for removing 82–99% suspended solids and 55–76% of oil products from heavily contaminated surface runoff (at their maximum concentration in the surface runoff 3000 and 10.5 mg/dm3, respectively). No decrease in the treatment efficiency was observed for 21 months, including the periods of negative temperatures (two seasons). During the tests the hydraulic discharge of the trapped pollutants from the FOPS®-S filter was carried out twice: suspended solids (~ 130 kg) and oil products (~ 2.1 dm3).

Mechanical Removal

Surface runoff from urban area is a potential source of pollution of water bodies. The composition of pollutants in surface runoff depends on various factors and seasons. The main pollutants are oil products, suspended solids, COD, chlorides and other mineral salts. Traditional wastewater treatment plants include the mechanical removal of large items, debris and leaves; sand removal; water clarification in accumulating settling tanks; chemical dosing, contact filtration and deep purification on sorption filters. Filters with inert floating polystyrene media of various types are widely used as first stage filters. The operation of industrial filters in the technological schemes of wastewater treatment strongly depends on the backwash efficiency. Floating media flushing is carried out in the direction from top to down using the water accumulated in the over-filter space. The article presents the results of the study of pulsed flushing on a model plant. Experimental study was conducted on the real wastewater treatment plant. The kinetics of suspended solids and oil products removal from filter media was studied. The operational parameters and mode of pulsed flushing were determined. The research results were used during the reconstruction of Moscow surface runoff water treatment plants.

Previous studies on the water quality of surface runoff often focused on the chemical oxygen demand (COD), nitrogen, phosphorus, and total suspended solid (TSS), but little is known in terms of the inorganic suspended solids (ISS). This research investigated the effects of ISS carried by surface runoff on the treatment efficiency of the pretreatment facilities and the ratio of mixed liquor volatile suspended solid to mixed liquor suspended solid (MLVSS/MLSS) of the activated sludge in a wastewater treatment plant (WWTP) with the anaerobic-anoxic-oxic (AAO) process in Chongqing city, China. The results showed that the surface runoff had a long-lasting impact on the grit removal capacity of the grit chamber, affecting the normal operation after the rainfall. In contrast, the primary sedimentation tank showed strong impact resistance with higher removal rates of COD, TSS, and ISS. Nonetheless, the primary settling tank aggravates the removal of organic carbon in sewage during rainfall, having a negative impact on subsequent biological treatment. The ISS in the surface runoff could increase the sludge concentration and decrease the MLVSS/MLSS ratio. After repeated surface runoff impact, the MLVSS/MLSS ratio in the activated sludge would drop below even 0.3, interrupting the normal operation of WWTP.

Introduction. The current state and the development of road construction and infrastructure is the cause of increasing the environmental pollution, especially in close proximity to the roads.Problem Statement. Surface runoff from the roads is a significant volume of polluted water which most often enters water bodies and the surrounding area without treatment, which is contrary to environmental requirements. Not only accidental leaks of oil and chloride residues present in runoff, but also a significant volume of suspended solids, which are often settled and accumulated and are dangerous for the environment and public health. In order to predict measures or prevent such pollution and accumulation, it is necessary to determine the sources of suspended solids, qualitative characteristics, physical and chemical properties of pollutants.Purpose. The purpose of the work is to determine of suspended solids pollutants (micropollutants), their components, to develop a classification of sources and their formation.Materials and methods. Analytical, information retrieval methods were used for this study.Results. As a result of the work, classification, which presents potentially possible types of micropollutants which are the components of suspended solids found in road surface runoff, was developed.Conclusions. The developed classification of micropollutants sources is the initial stage to study such kind of pollution, migration in the environment, the impacts of accumulation and decomposition products, as well as to develop measures for reducing the formation and dissemination of micropollutants in the environment.Keywords: road pavement, micropollutants, composition, particles.

Dominant Influence

Variations in water quality (conductivity, pH, suspended solids, Na, K, Ca, Mg, Cl, SO4, HCO3 and Si) during a major flood event that occurred in the Annan River, north Queensland, on 21 March 1985 are reported. Factor analysis showed that dilution of base flow concentrations by surface runoff was the dominant influence during the rising stage of the flood event, possibly with some flushing of ions from the surface layers of the catchment soils also occurring. At low river flow, the water quality was dominated by that in ground water and possibly interflow. Heavy metals were mostly transported in particulate forms (Fe 99%; Mn 95%; Pb, Zn, Sn c. 80%; Cu c. 60%). Filterable metal concentrations were low and changed little with flow.
