    Opis:
    Stormwater discharged from urban areas can contain significant amounts of heavy metals, especially zinc and copper. Roof runoff is very often directed into the soil and may pose a risk for groundwater quality. Lysimeter research has shown that zinc and copper contained in stormwater may be effectively removed by passing through vegetated soil. The average removal efficiency was greater than 90% and did not depend on the metal concentration in the influent, and the concentrations in the effluent met the limits for drinking water. Infiltration may be a reliable treatment method for roof runoff and may make stormwater safe for groundwater recharge.

    Opis:
    Model investigations of wastewater purification were carried out in a medium sand bed with an assisting natural clinoptilolite layer 0.10 or 0.25 m thick. The effectiveness of wastewater purification related to basic qualitative parameters was in accordance with the Polish standards on sewage disposal into grounds and surface water. Medium sand soil bed with the assisting natural clinoptilolite layer 0.25 m thick showed on average the removal efficiency regarding TSS higher by 3.3%, total nitrogen by 29.3%, total phosphorus by 25.9%, reduction efficiency regarding BOD5 by 1.1% and COD by 15.9% than that with the thinner clinoptilolite layer. The investigations confirmed that natural clinoptilolite with the granulation 1-5 mm can be used to enhance the removal of nitrogen and phosphorus compounds from wastewater with the application of infiltration drainage. However, very good effect of the TSS removal from the wastewater in the investigated soil beds can lead to their fast clogging under the infiltration drainage. Septic tanks should be designed in such a way that they retain as much TSS as possible, e.g., multi-chamber tanks instead of one-chamber ones.

    Opis:
    A pilot-scale subsurface wastewater infiltration system (SWIS) was designed for the treatment of polluted river water. The components of microbial communities have been identified and characterized and their dependences on some indicators of biofilm formation in the SWIS have been determined. The average efficiencies of COD, TN and removal were 43.3%, 28.8% and 79.6%, respectively. According to the denaturing gradient gel electrophoresis (DGGE) profile, high intensity and uniform bands were generated, indicating an abundant microbial community in each layer of the SWIS. Furthermore, the Shannon index analysis showed high correlation to the spatial distribution of microbial communities as well as the quantity of biofilm in each sample, which were characterized by measuring volatile suspended solids (VSS), phospholipids, proteins and polysaccharides. Sequencing of partial 16S rRNA gene fragments revealed that the composition of the total bacterial communities was dominated by Alphaproteobacteria, Gammaproteobacteria, Deltaproteobacteria, Pseudomonas, Bacillus, Flavobacteriaceae, TM-7, and other uncultured bacteria. These bacteria may contribute to nutrient removal in SWIS. +4 NH –N

    Opis:
    The objective of the undertaken investigations was to examine in laboratory conditions whether an introduction of an assisting opoka rock layer with the granulation of 1–6 mm into the ground improves the removal efficiency of nitrogen and phosphorus compounds from domestic sewage. The performed investigations concerned the layer supporting the removal efficiency of domestic sewage in a home sewage treatment plant under infiltration drainage. The model investigations of wastewater purification were carried out in a medium sand bed with an assisting, 0.10 and 0.20 m thick opoka rock layer. The effectiveness of wastewater purification related to basic qualitative indicators (total suspended solids – TSS, BOD5, COD, total nitrogen, total phosphorus) was in line with the Polish standards on sewage disposal into grounds and surface water. The medium sand soil bed with the 0.20 m thick assisting opoka rock layer showed higher effectiveness of wastewater purification than that 0.10 m thick. The application of the 0.20 m thick opoka rock layer increased the removal efficiency regarding TSS by 6.2%, total nitrogen by 20.4%, ammonium nitrogen by 8.3% and total phosphorus by 2.9%, and removal efficiency regarding BOD5 by 1.2% and COD by 1.9% with relation to the 0.10 m thick assisting layer (all percentages − in average). The results confirm that the natural opoka rock with the granulation of 1–6 mm can be used to assist in the removal of nitrogen and phosphorus compounds from wastewater with the application of infiltration drainage.
