Abstract The work is devoted to the task of simplifying the assessment of the effect of effluents from treatment facilities on the river hydrobiocenosis. The studies were carried out on the mountain river Uzh (Uzhgorod, Ukraine). Our approach to assessing the impact of waste treatment facilities on the river receiver is based on the estimate of the similarity of species composition and quantitative characteristics of populations of organisms from the aerotank and from the river. It is shown that the quantitative development of populations of species of ciliates from the aeration tank is a good indicator for assessing the degradation of organic matter coming with wastewater. The use of qualitative and quantitative characteristics of the protozoa from the wastewater treatment plant as a criterion for assessing the quality of the environment in the area of wastewater discharge showed their representativeness and effectiveness. The use of a limited number of species makes it possible to conduct an express assessment of the effect of effluents on receiving reservoirs for specialists working with activated sludge in the laboratories of treatment facilities.

Lake Toba, North Sumatera is one of the national tourism areas in Indonesia that has water pollution problem due to the unsustainable development especially in the catchment area. To support Lake Toba Tourism Area and to educate the people about sustainable development, Ministry of Public Works and Housing, Republic of Indonesia built integrated tourist toilets equipped with wastewater treatment plant at Menara Pandang Tele Area, one of the most strategic tourism attraction located in the catchment area of Lake Toba. The wastewater treatment plan is not only to use biofilter but also Kolam Sanita (wetland) as secondary treatment. This study would like to see how the wastewater treatment plant at Menara Pandang Tele is designed and see what modification are made from the original design to make it well functioned. This study uses a quantitative method to calculate the volume of the wastewater treatment plant. Further calculation is also needed to determine the dimension of the technologies. The geographical character is the main aspect to be considered in this step. The results showed that to meet the quality standard of the wastewater, the biofilter technology is determined to use three processing stages starting with equalization, primary sedimentation, and secondary process which consist of anaerobic process and clarifier. The dimension modification must not be more than two meters in height. Kolam Sanita is needed to make sure the effluent quality will not harm the groundwater. The modification is required due to the various heights of the ground level and makes the design representative of aesthetic function.

Carbon Fibres

Nitrous oxide (N2O) is a potent greenhouse gas that is emitted from wastewater treatment plants. To reduce emissions of N2O from swine wastewater treatment plants, we constructed an experimental aerobic bioreactor packed with carbon fibres (ca. 1 m3 bioreactor) as an alternative to conventional activated sludge treatment. The N2O emission factor for the aerobic bioreactor packed with carbon fibres (CF) was 0.002 g N2O-N/g TN-load and the value for the typical activated sludge (AS) reactor was 0.013 g N2O-N/g TN-load. The CF treatment method achieved more than 80% reduction of N2O emissions, compared with the AS treatment method. The experimental introduction of a CF carrier into an actual wastewater treatment plant also resulted in a large reduction in N2O generation. Specifically, the N2O emission factors decreased from 0.040 to 0.005 g N2O-N/g TN-load following application of the carrier. This shows that it is possible to reduce N2O generation by more than 80% by using a CF carrier during the operation of an actual wastewater treatment plant. Some bacteria from the phylum Chloroflexi, which are capable of reducing N2O emissions, were detected at a higher frequency in the biofilm on the CF carrier than in the biofilm formed on the AS reactor.

The Individual

Industry and industrial complexes are often located in the proximity of people’s homes. One of the negative effects of industry is noise emissions into the surrounding environment. With the increasing concentration of the human population and the increase in industrial production, more and more people are exposed to the negative effects of noise. This article discusses a comprehensive approach to reducing noise emissions from industrial operations, and the subsequent impacts on surrounding villages and human health. The first step of the whole process is to understand the current state of the acoustic situation in industrial operation and in the nearby villages, an important part of which is the identification and localization of dominant noise sources. For this purpose, a unique noise visualization tool was used, namely, an acoustic camera. The next important step is to propose a technical solution and measures to reduce the noise of the individual source. Consequently, it is necessary to create a mathematical model, i.e., noise maps, in order to verify whether the proposed measures will be sufficient. Once the proposed measures have been implemented, verification of the effectiveness of these measures needs to be carried out through repeated noise measurements in nearby villages and also on the site of the industrial installation. The above procedure was applied to the operation of a wastewater treatment plant that was causing noise exceeding the permissible levels in the surrounding villages. The application of this approach, the implementation of the proposed measures, and the subsequent verification confirmed a significant reduction in the noise levels in the affected villages, and the measures implemented were assessed as highly effective.

Effluent Quality

Achievement of good effluent quality is always the main goal for wastewater treatment plant (WWTP) systems. However, these WWTPs have developed further objectives that include efficient design and strategic control options, with the prospect of their conversion into waste resource recovery facilities (WRRFs) that operate on reduced energy costs. With all these aspects becoming an intrinsic part of waste treatment, mathematical models that simulate WWTP unit processes are becoming of increasing relevance for the achievement of WRRF goals (including good effluent quality, low energy costs and nutrient recovery). It is expected that these mathematical models will benefit potential future applications of automation process control, which have also been developing rapidly with the availability of more reliable and affordable sensors. However, simulated automation control strategies require a thorough evaluation protocol to ensure their viability prior to being adopted as efficient operation control measures. This study considers the comparison of different control strategies implemented on a standard WWTP layout, for plant optimization. The initial task was to define performance indices, effluent quality index (EQI) and operation cost index (OCI), based on a previous investigation by the International Water Association (IWA) benchmark simulation modelling (BSM) task group. These performance indices were then used to evaluate the following strategies: (i) adding a fermentation tank, (ii) dosing flocculant and (iii) implementing a balancing tank. A control strategy was only assumed to be effective with improvement or maintenance of effluent quality. Overall, the evaluation exercise proved to be useful for providing expert advice on efficiency of proposed waste treatment system layouts, towards determination of the best configuration of future WRRFs. For instance, it was notable that significant organic strength is needed for removal of nutrients recycled back from the anaerobic digestion (AD) system into the activated sludge (AS) – hence alternate methods to put the nutrient-rich outflow from the AD system to good use are required.

Health service activities at the Clinical Laboratory produce infectious and non-infectious waste in the form of solid or liquid. Clinical laboratory liquid waste is one source of environmental pollution if the concentration exceeds the standard quality of wastewater. Polluted water quality parameters include microbiologics of Coli / Total Coliform Germs. Water quality with microbiological parameters can be used to determine the presence of bacteria, viruses, parasites. Bacteria used as indicators are Coliform bacteria. At present several clinical laboratories have implemented a Liquid Wastewater Treatment Plant. So that the waste discharged into the environment meets the standard quality standards for hospital liquid waste, and minimal pollution. This study aims to determine the quantity of Total Coliform at the inlet and outlet points of the Wastewater Treatment Plant Laboratory Medical Liquid. The results showed that the quantity of Total Coliform at the inlet sampling point of the liquid media waste at the Wastewater Treatment Plant Laboratory reached the highest value > 1.6 x 105 MPN / 100 ml, and after processing at the Wastewater Treatment Plant Laboratory decreased to 0 MPN / 100 ml (no coliform was found ), and with the highest value of 2.7 x 103 MPN / 100 ml, according to the waste water quality standard.
