The measurement of total oil and grease (TOG) and total petroleum hydrocarbon (TPH) in water and soil samples by means of infrared (IR) absorption is a widely used analytical procedure. It is relatively easy to use, requires little ancillary equipment and is sensitive enough to provide data on TOG and TPH content in the range of permissible concentration levels. Furthermore, IR instrumentation ...

The concentration of dispersed oil and grease (OG) is an important parameter for water quality and safety. OG in water can cause surface films and shoreline deposits leading to environmental degradation, and can induce human health risks when discharged in surface or ground waters. Additionally, OG may interfere with aerobic and anaerobic biological processes and lead to decreased wastewater tr...

Pharmaceutical industry represents a range of industries with operation and processes as diverse as its product. Hence effluents coming from pharma industries vary from industry to industry. Thus it is almost impossible to describe a typical pharmaceutical effluent because of such diversity. Waste water is generally evaluated in terms of temp, pH, Total suspended solid (TSS), BOD, COD, Oil & gr...

The monitoring and performance evaluation studies were carried out for an effluent treatment plant of a refinery located in the western region of India. The samples from the inlet and outlet locations of ETP were collected at regular intervals and were analyzed for different parameters. The pH, oil & grease, BOD, COD, suspended solids were found to be reduced significantly, where as the pH of t...

The aim of this research was to determine the characteristics, volumes and treatability of Full-service carwash wastewaters in Toluca (Mexico State). The average water use for Exterior-only wash was 50 L per small-size car and 170 L per medium-size vehicle (pick up, van or light truck). The Full-service wash (exterior, engine and chassis) required 170 L per small-size car and 300 L per light tr...

C8 Phased Out of Food Wrappers In July 2012 the U.S. FDA released a statement that manufacturers had voluntarily ceased selling agents containing the compound C8 for food-contact use the prior summer. At that time, manufacturers had predicted stocks of the agents and packaging containing them would be depleted within a year. C8, or perfluorooctanoic acid, was used to keep oil and grease from se...

Case Report A motor cycle mechanic aged 39 years sustained an injury to the inner corner of the left eye with a jet of oil from a grease-gun. In spite of considerable bruising of the lids and conjunctiva, discomfort in the eye was minimal, so he was not referred to Moorfields until 4 days after the accident. Examination.-The right eye was found to be normal and the visual acuity 6/6 unaided. In...

We investigated conventional characterization of wastewaters of the "Kullar Domestic Wastewater Treatment Plant." In the study of conventional characterization; 23 composite samples, which were taken during 10 months, were used and analysed as COD, BOD5, TKN, NH3-N, SS, VSS, TP, RP, TS, Alkalinity, oil and grease, detergent, chloride parameters. For determine of the plant efficiency, 8 output g...

In Amsterdam, over 200 so called inverted siphons are situated. As these siphons are prone for blockages, it is key that these parts of a sewer system are maintained proactively. This article outlines the basis of a methodology that can be used to estimate the fouling degree of sewers with the use of water level measurements. Even though the measurement period appeared to be of restricted lengt...

Mechanical degradation by shear is one of the mechanisms that limits life-time lubricating grease in a rolling bearing. It results change micro-structure thickener–oil system, leading to bleed and consistency. The resistance can be quantified using worker. In this article, novel approach described, where worker used measure rheological properties situ, while aging grease. energy pressure losses...
