Planning for a communal scale Wastewater Treatment Plant (WWTP) in Depok Village, Trenggalek Regency, East Java is needed because most of the wastewater Village only treated with septic tanks. This study aims to plan WWTP design based on generation domestic and non-domestic Village. The planning this was carried out results laboratory test parameters pH, TSS, BOD, COD, total coliform, fatty oil...
Direct Capillary Nanofiltration (Direct CNF) is a new technique used for surface water and wastewater treatment in one step without pre-treatment. The CNF membrane module combines the favourable cleaning properties of capillary ultrafiltration membranes with the favourable separation properties of nanofiltration membranes in terms of removal of DOC, colour, bacteria, viruses and pesticides. Dir...
Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...
Within the last decade, reproductive abnormalities have been discovered in wild amphibian populations of multiple species and in a variety of regions in North America. Predominantly, these field studies have focused on agricultural landscapes. In this study, we worked in suburban environments based on preliminary evidence showing that amphibian populations can display surprisingly high frequenc...
The effect of municipal wastewater irrigation on the yield and quality of vegetables and crops was studied by means of pot and lysimetric experiments. The pots were seeded with lettuce salad, radishes, and carrots in all experimental years; the lysimeters were planted with early potatoes in 2005 and 2007, and with sugar beet in 2006. Secondary-treated wastewater (in 2005) or only primary-treate...
Wastewater was collected from the Dheradun industrial area situated in capital of uttrakhand. Samples were collected between the periods of November 2010 to Aug.2011 determine the following parameters, pH, temperature, turbidity, chemical oxygen demand (COD), Biological oxygen demand(BOD), dissolved oxygen (DO), conductivity, total dissolved solid (TDS), total suspended solid (TSS), sulphate, n...
Floating islands are a form of treatment wetland characterized by a mat of synthetic matrix at the water surface into which macrophytes can be planted and through which water passes. We evaluated two matrix materials for treating domestic wastewater, recycled plastic and recycled carpet fibers, for chemical oxygen demand (COD) and nitrogen removal. These materials were compared to pea gravel or...
The objective of this study was to determine changes in the chemical composition of water that result from its use by the town of Bucyrus in Crawford County, OH, and to document the effect of the discharge of wastewater on the quality of water in the Sandusky River. The results indicate that the wastewater is enriched in the major elements (Na, K, Mg, Ca, and Sr) compared to tap water in the to...
Wastewater treatment issues are extremely important for humanity. Their consideration becomes more than a necessity, a responsibility and every producer must improve their treatment processes. The efficiency increasing of these processes has been done in two ways: 1. by technological way various types of treatment were developed during the past years and this domain has almost no technological ...
This work has examined the effects of pH on treatment efficiency and biomass production rate water hyacinth ponds (WHP) treating domestic wastewater. Experiments were carried out outdoor in WHP, working under batch subtropical environmental conditions, using pre-treated sewage with varying from 5 to 9. It was observed that plants regulated medium within 6.4 7.1 during processes independently in...
