Every river gets polluted as it moves from its source to the end. Hence, quality of water requires investigation for usability. In present work 40.69 km stretch Tungabhadra in Davangere district Karnataka, India was chosen testing quality. The samples’ physical, chemical and biological characteristics were tested eight sites each month during pre-monsoon, monsoon post-monsoon seasons 2017 2019....

normal 0 false false false en-us x-none fa background: nowadays wastewater is one of the important sources of environmental pollutions and   one of the aims of wastewater treatment is to maintain a healthy environment. nonstandard wastewater discharges and their use in agriculture or discharge to surface water will follow environmental and health hazards. the aim of this study was to compare th...

This study evaluated the effectiveness of soils with different textures and thickness to treat BOD, N and P eluted from household septic effluent. The assessments were accomplished by leaching undisturbed soil monoliths of 30, 45 and 60 cm thickness and 25 cm in diameter, representing the four different textural groups and hydraulic loadings recommended by the Kentucky Health Department, with d...

In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...

Abstract This paper aims to assess the requirement of load reductions and flow augmentation enhance assimilation yield Yamuna River, Delhi. The framework QUAL2kw was used predict river quality. model calibrated confirmed in critical conditions pre-monsoon periods. Three strategies were established for varying pollutant loads. dissolved oxygen (DO) concentration predicted with changing biochemic...

WSPs are widely used in North America, and offer huge potential for other continental climate regions. The standard design and operating protocol is robust even at high latitudes, but may be conservative elsewhere. A simple model based on first-order kinetics for biochemical oxygen demand (BOD) is used to consider some alternative design and operating protocols, using long-term daily climate re...

Microenvironmental studies regarding plant oxygen release in a wastewater environment are important to understand the principles of constructed wetlands for wastewater treatment. pH, oxidation reduction potential (ORP), and dissolved oxygen (DO) microprofiles for the lateral and main roots of the bulrush (Scirpus validus) in a vertical flow constructed wetland fed with municipal wastewater were...

Biochemical products have been widely used for treatment of various types of wastewater. The treatment processes with the addition of biochemical products are quite attractive because of their simplicity, minimal use of equipment, they are environmentally friendly and are suitable for the removal of organic pollutants. The purpose of these products is to enhance the activities of beneficial mic...
