The waste oil produced from the domestic and industries generates destructive effects on the environment. Discarding waste cooking oil (WCO) in the open causes water pollution due to poor solubility and creates a film on the water, which hinders diffusion of oxygen and results in a toxic effect...
WATER POLLUTION CONTROL IN PETROLEUM REFINERIES Not shown in Figure 2 due to Iack of space, is the so ur wM.er system. Process waters contaminated by sulphides, ammonia and phenols are sent to steam strippers before going to the secondary treatment system. One problern with this type of o...
Article 10To prevent and control water pollution, it is necessary to make unified plans on the basis of river basins or regions. Plans for preventing and controlling water pollution of basins of major rivers, designated as such by the State, shall be formulated by the environmental protection de...
The petroleum refining capacity in Sweden will probably increase from some 13 million tons of crude oil in 1970 to an annual capacity of about 40 million tons at the end of the seventies. A committee formed with members from the Swedish Petroleum-Refining Industry and the Environmental Protection...
Oil pollutionPhoto: Oil-tanker spills are the most spectacular forms of pollution and the ones that catch public attention, but only a fraction of all water pollution happens this way. Photo by Lamar Gore courtesy of US Fish & Wildlife Service Photo Library and US National Archive....
[30]. This may result in a drop in dissolved oxygen levels, which would kill aquatic life. Approximately 13% of all oil pollution, it has been reported, is caused by oil spill transportation [104]. On the other side, plastics can collect in water bodies, especially oceans, and take ...
Water pollutionis a large set of adverse effects upon water bodies such as lakes, rivers, oceans, andgroundwatercaused by human activities. Although natural phenomena such asvolcanoes, algae blooms, storms, and earthquakes also cause major changes inwater qualityand the ecological status of water,...
oil spill best illustrates a point source water pollution.A nonpoint source delivers pollutants indirectly through environmental changes.An example of this type of water pollution is when fertilizer from a field is carried into a stream by rain, in the form of run-off which in turn effects aquat...
oil refining, fertilizer production, and other chemical plants, thermoelectric power production, and naturalgas extractionfrom shale rock, water is also being used. Discharge of untreated water coming from these processes is pollution, which includes discharged solutes (chemical pollution) and increased ...
and oil refineries, use large quantities of water for cooling and return it at elevated temperatures. Suchheated watercan alter the existingecology, sometimes sufficiently to drive out or kill desirable species of fish. It also may cause rapid depletion of the oxygen supply by promoting algal bloo...
