Monitoring of work of the aeration tanks of operating town treatment plants is done. Based on the obtained results a conclusion has been drawn that sewage water is improperly treated from ammonium nitrogen. The velocity of the aeration process, depending on the concentration of dissolved oxygen and ammonium nitrogen, is investigated. The obtained investigation data became the basis for modeling the aeration process in industrial conditions depending on the required initial concentration of ammonium nitrogen.

This paper reports on the intentions of urban residents in two South Australian Local Government Areas (LGAs) (council areas) to use stormwater treated through a managed aquifer recharge process for various potential non-potable uses. Data were collected through an online survey of the residents in these LGAs. The key finding is that, in common with recycled sewage water, the intention to use treated stormwater was lower for uses having closer contact with people. A hypothesized model consisting of possible factors influencing the intention to use treated stormwater was developed based on the contemporary literature relating to usage of treated sewage water. Greater trust in the local water authority was shown to be associated directly and closely with a lower perceived health risk. A positive attitude by respondents to the use of treated stormwater (as an aspect of a sustainable future) was found to be more likely to result in an intention to use the treated stormwater for non-potable purposes. Respondents' perceived health risk, emotions and environmental concerns all had significant associations with their attitudes to using stormwater but were not associated with their intention to use it.

The Impact

This study was conducted to determine the impact on the nutrient status of soil and vegetable crops irrigated with the treated sewage water. Three samples of water and five samples of soil and five commonly grown vegetables viz. radish, carrot, spinach, cauliflower, and potato were collected from Ganjia, Arail and Dandi located in Naini, Allahabad (India). The water samples were analysed for pH, EC, and heavy metals (Pb2+, Cr3+, Cd2+ and Ni2+) concentration. Water samples from all the sites were alkaline with EC below the safe limits. The soil and plant samples from all the three sites showed that Gangia recorded the highest value of EC (dS m-1), organic carbon (OC) (%), available NPK (kg ha-1), and micronutrients concentration (Mn2+, Zn2+ and Fe2+) (mg kg-1) whereas, the lowest concentration was recorded at Dandi followed by Arail. The soil samples collected from all three sites were alkaline. The nutrient status (N, P and K) showed the highest value in potato in the three sites, whereas manganese and zinc showed the highest value in spinach and iron in carrot.  The study concludes that treated sewage water used for irrigation has a positive impact on nutrient status in soils and as well as in vegetable crops.
