Abstract Aerobic sludge from a municipal activated sludge treatment plant, sludge from a conventional municipal anaerobic digester, aerobic sludge from an activated sludge process of a petroleum refinery, and granular sludge from an upflow sludge blanket reactor (USBR) were tested in the deemulsification of a water-in-oil emulsion. All sludges except the last one, showed a good deemulsification capability and could he used for a partial deemulsification of such emulsions.

Summary There are a lot of sludges produced in oil production and storage processes in Liaohe Oil Field. Usually complicated chemical processes are involved in treating the sludge effectively and such surface-treatment processes are subject to high cost and environmental challenges. Therefore, the feasibility and performance of sludge injection into steam-stimulated wells, and sludge sequestration and associated heavy-oil-recovery improvement are investigated on the basis of results of laboratory research and field operation.

Abstract:

The clarification process is the separation of oil from the sludge using a sludge centrifuge. The process in this sludge centrifuge treats sludge/sludge output from CST in the form of sludge underflow. The problem that occurs in the oil separation process in the centrifuge is the high amount of oil that is still included in the final effluent as oil losses. High oil loss is caused by a blockage in the nozzle due to the operational process of the tool that does not pay attention to procedures (SOP) and the lack of operators in the sludge centrifuge related to the maintenance process (washing).

The oil producing and petroleum refining industries dispose of a significant amount of oily sludge annually. The sludge typically contains a mixture of oil, water and solid particles in the form of complex slurry. The oil in the waste sludge is inextractible due to the complex composition and complex interactions in the sludge matrix. The sludge is disposed of on land or into surface water bodies thereby creating toxic conditions or depleting oxygen required by aquatic animals.

It was found that the addition of sludge leads to an increase in the density of the samples. Thus, the samples without the addition of sludge have an average density of 860 kg/m3, samples with the addition of sludge in an amount of 10 mass% - 875 kg/m3, 20 mass% - 879 kg/m3, 30 mass% - 882 kg

The clarifier station is also known as a purification station. Its main function is to obtain palm oil in a very pure condition. There are several machines ready to work to refine Crude Palm Oil from palm oil. One of the machines at the refining station is the Sludge Separator which has the function of extracting oil that is still contained in a centrifugal manner where water and NOS with a specific gravity greater than oil will be thrown out and oil will enter the interior. The Sludge Separator method separates oil from water and NOS, namely by rotating (spinning) the bowl that has been insta

Sludge from soda production are dumped into sludge collectors, which have a negative impact on the environment. There is a threat of contamination of groundwater with a highly mineralized still waste liquid. The increase of sludge in sludge reservoirs creates additional pressure and increases infiltration into groundwater. These processes are harmful for the ecological situation in the region. In this paper modification of soda sludge produced by organosilicon liquid, sodium liquid glass

Automobile-service-station wastes make for an acute environmental concern because they contain polyaromatic hydrocarbons, heavy metals, surfactants, and other harmful elements. An eco-friendly way to treat and take advantage of these wastes is embodied in the concept called "valorization". In the present work, valorization is described as a chemical process to remove solids from contaminated water and to stabilize oily sludge into a saponified product. Electrocoagulation and coagulation with aluminum were applied to separate oil-water emulsions and removed 99.7% of turbidity. Both coagulation

AbstractThe palm oil industry is one of the most important agro-industries for tropical countries because of the unique properties and wide range of uses of palm oil for various end products. In a palm oil extraction process, a large quantity of water is required, of which half the quantity will end up as effluent. This palm oil mill effluent (POME) has an extremely high content of organic matter, which can cause severe pollution of waterways and other environmental problems. Disposal of this highly polluting effluent has become a major problem for the palm oil mills. Therefore, several method
