An experiment was conducted to determine the effect of supplementing diets fed to growing pigs with fat sources differing in their composition of fatty acids on the apparent total tract digestibility (ATTD) of minerals. A diet based on corn, potato protein isolate, and 7% sucrose was formulated. Five additional diets that were similar to the previous diet with the exception that sucrose was rep...

Executive Summary A series of experiments were performed in a small but full-scale CDS device to determine its ability to remove free oil and grease from polluted waters using sorbents. Nine experiments were performed using five different sorbents. One control experiment was performed without a sorbent. The sorbents were allowed to float on the surface of the separation chamber of the CDS devic...

The analysis of grease-lubricaled rolling element bearings i s presented. Exferimen tally determined flow curaes for grease are found to be well correlated by the Herschel-Bdkley model flow eqzration. A theory for predicting roller Jilm thickness based on the assumed flow model i s derived. Experimental results show that grease will deveIop a larger film lhickness lhan the grease base oil at ji...

Three growth trials and one digestion trial were conducted to compare the effect of dietary fat sources and combinations on starter pig performance, nutrient digestibility and intestinal morphology. Growth trials 1 and 2, utilizing a total of 324 weanling pigs (21 +/- 3 d), were conducted to determine the influence of addition of soybean oil, coconut oil, choice white grease, 50% soybean oil: 5...

in this research performed during 1993-1994, the effluent of behran oil refmery, in south of tehran, which produces different types of industrial oil and greases, was studied and 3 methods of gravity separation, coagulation and flocculation and dissolved air flotation were investigated. in the first phase of the survey, the quality and quantity of the effluent were determined. this showed an av...

An environmental friendly palm-grease has already been formulated from modified RBDPO (Refined Bleach Deodorized Palm Oil) as base oil and lithium soap as thickener. Such palm-grease is dedicated for general application and or equipment working in areas where biodegradability is required such as in agriculture, forestry and coastal marine, recreation areas. The grease was manufactured via 4 ste...

Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability...

This research investigated the application of Bio-Amp, a commercial bio-additive for the treatment of fat, oil, and grease (FOG) in a grease trap, and evaluated potential impacts of treated effluent on downstream collection system and treatment processes. Results show that after Bio-Amp treatment, FOG deposit formation was reduced by 40%, implicating a potential reduction of sewer line blockage...
