INTRODUCTION The ARO Corporation based in Bryan, Ohio is part of worldwide Ingersoll-Rand and manufactures industrial fluid power and fluid handling equipment of world class design, function and durability. Their piston and diaphragm pumps are air operated, of rugged construction, and their broad material compatibility insure long, dependable service life. The pumps are used in a variety of app...

in this present study the dissolved air flotation (daf) system was investigated for the treatment of kermanshah oil refinery wastewater. the effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (cod) removal was examined experimentally. all the experiments were done under a...

Background There has been an alarming increase in the dumping of Hong Kong’s municipal solid waste (MSW), predominantly food waste, in landfill (9,547 tonnes of MSW per day in 2013) [1]. One way of promoting an environmentally friendly method of minimising food waste is to turn the waste into energy by producing biodiesel from waste cooking oils. Biodiesel is a biodegradable fuel that can be ma...

The increasing vehicular population causing consumption of petroleum fuels at a faster rate and causes increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The situation off...

This study proposed a novel way for global greenhouse gas reduction through reusing China's waste oil to produce biofuels. Life cycle greenhouse gas mitigation potential of aviation bio-kerosene and biodiesel derived from China's waste oil in 2010 was equivalent to approximately 28.8% and 14.7% of mitigation achievements on fossil-based CO2 emissions by Annex B countries of the Kyoto Protocol i...

treatment efficiency, design factors and kinetic coefficients were studied using two pilots of activated sludge (as) and powdered activated carbon technology (pact), for treating tehran oil refinery effluent, in a duration of more than 12 months in order to evaluate the performance of each system against growth inhibitor shock loads, different concentrations of phenol and furfural (10-300 mg/l)...

In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...

Experiments are described which demonstrate that asphaltenes precipitated from a refinery tar using an excess of n-heptane spontaneously partition into a contacting water phase in the presence of an ethoxylated nonionic surfactant by effecting a temperature change. The process appears to be related to the temperature-dependent phase behaviour of the particular surfactant. Hot (ca. 80-90°C) aque...
