    摘要: A method for removal of hydrocarbon materials from solid particulate soil contaminated with the hydrocarbon materials. The method comprises forming an aqueous slurry of a mixture of a hydrophobic adsorbent selected from foamed synthetic materials or natural materials which entrap gas, with the soil in the presence of water. The adsorbent has a density less than water. The slurry is mixed for a period of time, and a gravity separation of the adsorbent from the aqueous admixture thus obtained is effected.

    摘要: Paunch-sludge from an abattoir is mixed with the fatty DAF-float from an abattoir, and placed in a shearing vessel. The mixture of the two material thickens the medium in which the matted strands are contained, enabling shearing to be more effective; so much so that paunch-sludge can now be sheared to a homogeneous liquid. The technique can be used with other sludges and other fatty waste materials.

    摘要: Sewage sludge is dewatered to a cake-like state. The viscosity of the sludge is lowered by admixing a quantity of urea, urea-ammonium-nitrate, or other nitrogen-containing material, in with the dewatered sludge. The treatment also removes pathogens, and renders the product suitable for use as a fertilizer.

    摘要: Disclosed herein are cylinder forming apparatuses for making nonwoven webs. In one embodiment, a cylinder forming apparatus has a first source configured to dispense a first fluid flow stream, and a second source configured to dispense a second fluid flow stream, wherein at least the first fluid flow stream comprises a fiber; an arcuate mixing partition downstream from the one or more sources, the arcuate mixing partition positioned between the first and second flow streams, the apparatus defining one or more openings that permit fluid communication between the two flow streams; and a cylindrical receiving region situated downstream from the sources and proximal to the first flow stream and designed to receive at least a combined flow stream and form a nonwoven web by collecting fiber from the combined flow stream. Methods of using the apparatuses are also disclosed.

    摘要: Sewage sludge that has been de-watered to 25% solids is subjected to a combination of shearing and heating that liquefies the sludge, and drops its viscosity to below 12,000 cP. The fact of liquefaction prepares the sludge such that subsequent drying can be done more cost-effectively than hitherto. After drying, the dried sludge can be incinerated.

    摘要: Estimating bandwidth of a transport connection from higher layers. In an embodiment, the bandwidth is estimated as a function of the window size, the time taken to transfer a transport payload of window size from the sender system to the receiver system, and a conclusion indicating whether the window size is limited by the network or by the resources on the receiver system. All the factors used in the bandwidth computation are determined based on round-trip times of transport payloads of different sizes transferred between the sender system and the receiver system.

    摘要: A process for breaking an oil-water emulsion. The process comprises contacting the oil-water emulsion with a bacterial culture produced by growth in a liquid medium containing hydrocarbons under non-sterile conditions. The oil-water emulsion and bacterial culture are contacted under conditions that minimise degradation of the oil. The oil-water emulsion is permitted to form an oil layer and a water layer, which are then separated. The process is particularly useful in the treatment of slop-oil emulsion in the petroleum industry.
