روش های موجود و رایج برای تصفیه آب (استفاده از مواد منعقد کننده معدنی) هم از لحاظ سلامت و هم از لحاظ اقتصادی مقرون به صرفه نیستند. لذا پژوهش هایی جهت کاهش میزان مصرف این مواد برای تصفیه آب صورت پذیرفته است. یکی از این روش ها استفاده از اثر میدان مغناطیسی بر روی خواص آب برای تصفیه بهتر آن می باشد. در این پژوهش اثر میدان مغناطیسی بر روی آب در جهت کاهش کدورت آن در حضور دو منعقدکننده سولفات آالومین...
Indonesia, an archipelago with vast coastal areas consisting of 809 villages, still faces the same problems clean water scarcity and accessibility. This research goals are to discover appropriate inexpensive local filtering media lower salinity brackish in Sidoarjo Regency Indonesia. Regarding previous invention research, this study deploy experimental method by physical experiment including ma...
In this study, a detailed hydrochemical evaluation has been made to determine the chemical processes of spring waters and their suitability for irrigation. The study area consists drainage basin Gökpınar dam fertile soils irrigable agriculture. During period August 2017 October 2018, regular samples were collected monthly from 10 140 in total subjected analysis. For purpose, 11 parameters such ...
In this study, the Scallop bivalves were used for biofiltration of wastewater in shrimp farms during spring 2018 from Guowater Bay. Sedimentation, biological and aeration ponds were prepared for biofiltration around the main pool, then, oyster bivalves were collected from natural environment (sea) and were placed in these pools. Concentration of quality parameters were investigated in four samp...
A study was conducted to evaluate the spatial and seasonal variation in quality of surface water sources along national highway, state highway link road. Physicochemical properties were estimated using samples collected during pre-monsoon, monsoon, post-monsoon seasons year 2018 2019. The parameters (pH, EC, Turbidity, TDS, BOD, COD, Cl-, NO3- heavy metals) calculated. investigation revealed th...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
the present paper deals with criminal issues. for example, legal injunction on the necessity of returning a deposit has a legal nature and legal injunction on the punishment of those who breach the trust has a criminal nature. existing social issues are the basis of classification of some instances into the issue, some of which are based on variation and others on quality. therefore, the motiva...
Durian peel can be the main contributor to agricultural wastes and becomes an environmental problem when it is discarded into landfill site or even burning it. The average of entire durian fruit weight about 255,353 MT for all over country. loading rate landfills increasing, especially with massive amount size waste that requires a larger space dispose of. Therefore, certainly important utilize...
Groundwater aquifers are an important source of water supply for agriculture, industry and drinking. The present study investigates the changes in the quality of groundwater using geostatistical methods in the Ravar plain during a 10-year period. In this study, after selecting the appropriate spatial interpolation method to draw water quality parameters such as TDS, SAR and EC, zoning maps of R...
Because hydroponic plant nutrient is dissolved in the water, water quality management essential for growing healthy plants. Taking care of total solids (TDS) and pH (water acidity) essential. The purpose this research to create a IoT-based monitoring device. average TDS after 30 days automation with an Arduino UNO was 1162.82 ppm, gadget kicked on pump whenever fell below 1000 ppm or EC 2. mech...
