This study provides a comprehensive review of the efforts utilized in measurement water quality parameters (WQPs) with focus on total dissolved solids (TDS) and suspended (TSS). The current method used TDS TSS includes conventional field gravimetric approaches. These methods are limited due to associated cost labor, spatial coverages. Remote Sensing (RS) applications have, however, been over pa...

Quality of river varies widely depending on the land use in the catchment and environmental factors. Many rivers in developing countries are unhealthy because they contain harmful physical, chemical and biological agents. Zanjanrud River, located in Zanjan Province, Iran, where recently faced human intervention needs a regular monitoring from upstream to downstream for sustainable management. H...

Palm oil mill effluent (POME) poses a great threat to the environment. However, it contains valuable resources such as energy, water and nutrients that could be recovered for sustainable development. Currently, anaerobic digester has been employed to recover the energy potential in POME. However, the presence of suspended solids in the digestate hinders the downstream nutrients recovery process...

Irrigation is a dry season agricultural activity that was known to man for centuries. Agricultural runoff has been identified as the major nonpoint sources of pollution into surface waterbodies which changes physico – chemical parameters thereby impacting on biodiversity such ecosystem. River Ngadda receives pollutants from irrigational sites along river bank. The study aimed at assessing impac...

A benchmark for the test of control scenarios of sequencing batch reactors (SBR) used for wastewater treatment is proposed. The plant layout includes a buffer tank for wastewater storage in front of the SBR. Performance criteria based mainly on the quality of the effluent are given. The use of the benchmark is illustrated by the study of the effects on the effluent of the control of dissolved o...

Background & Aims of the Study: The wastewater created as a result of stone cutting industries enters some pools for re-consumption so that its suspended solids settle by gravity. By taking to account the high volume of water and sludge, treatment of wastewater and removal of sludge cause many problems for stone cutting units. The objective of this study was to determine the quality of wast...

The performance of a novel industrial membrane bioreactor (MBR) comprising denitrification, nitrification and ultrafiltration for the secondary treatment of primary treated animal rendering wastewater has been compared with an experimental, low-cost and novel vertical-flow constructed treatment wetland planted with Typha latifolia L. The process wastewater followed pre-treatment by dissolved ai...

In recent years, in Korea, recirculating aquaculture technologies for intensive fish culture are increasingly being used to enhance production of a high quality aquacultural products all year around including seawater. In high density aquaculture system, the increase of protein and organic particulates by uneaten feed, feed waste and excreta of fish gives a bad effect in fish growth and environ...

The wastewater from petroleum industries contains high organic matter content, oil and grease, dissolved solids and turbidity. The petroleum wastewater normally treated in a plant comprising of primary, secondary and tertiary treatments. The high organic loading needs to be treated in biological treatment step. Biological treatment can be suspended growth or attached growth type. Activated slud...
