In order to determine the interactions between anaerobic bacteria and the performance of the upflow anaerobic sludge blanket, UASB, chemical oxygen demand, COD, volatile fatty acid, VFA, and methane gas productions were determined. The variations of anaerobic microorganisms in the anaerobic granular

Sediments can accumulate various pollutants and are widely used for environmental monitoring of human impact. The central purpose of this study was to examine the levels of eight heavy metals in subtidal sediments in the vicinity of two thermal power/desalination plants in Oman: (1) the Barka power/

Catalytic dechlorination of para-nitrochlorobenzene (p-NCB) by Ni/Fe (nickel/iron) bimetallic nanoparticles was carried out. The catalytic reduction and dechlorination reaction was believed to take place on the surface site of the nanoscale catalysts. In the reaction, Ni plays a role of catalyst dec

A PVC membrane with 4-hydroxy salophen as an ionophore along with sodium tetraphenyl borate (NaTPB) as an anion excluder and dibutyl phthalate as a solvent mediator in the ratio 28.7:3.3:63.2:4.7 (w/w) (PVC–NaTPB– DBP–ionophore) exhibits good properties with a Nernstian response of 30.1 ± 1.0 mV per

In this paper, an attempt has been made to evaluate the internal heat transfer coefficient of single and double slope passive solar stills in summer as well as winter climatic conditions for three different water depths (0.01, 0.02 and 0.03 m) by various thermal models. The experimental validation o

The production by enzymatic treatment of fish protein hydrolysates (FPH) is a promising route to add value to fisheries proteinic co-products (fish frames, heads etc.). Indeed, FPH possess good nutritional properties and biological activities for food and feed uses. Pressure-driven membrane separati

As the result of a conventional wastewater treatment such as activated sludge process, an excess sludge is produced and must be disposed of safely. Recently, increased attention has been given to a minimization of waste sludge in a wastewater treatment process. In this study, hydrogen peroxide oxida

Two parallel pilot-scale biological filters which used manganese sand and silica sand as media respectively were tested for the removal of iron and manganese from drilled well water in Harbin. Iron and manganese oxidizing bacteria were isolated and used as inoculums for filter start-up. Manganese sa

The city of Batman, located in the southeastern part of Turkey, has lately been receiving national attention because of its oil reserves and production, and cultural, tourist attractions and rapid industrialization. There is no information about radioactivity measurement reported in water samples in

A dynamic model is developed for a tubular reverse osmosis unit. The proposed model considers the unit as a series of single tubes, each tube is described by a single ordinary differential equation (ODE) and the whole module is to be described by sets of differential algebraic equations. The tubes a
