Causes Of Thermal Pollution - what

Thermal pollution is defined as a sudden increase or decrease in normal temperature of a natural body of water, for eg. Causes of Thermal Pollution. Deforestation : Natural tree cover reduces the exposure of water bodies to direct sunlight. Runoffs from paved areas in urban areas during summer time adds to the warming of water bodies. Relatively small and shallow Retention ponds , absorb much sunlight, thus causing water temperature to rise. Domestic sewage apart from causing water pollution also causes thermal pollution. Effects of Thermal Pollution. The warm water holds relatively less oxygen than cold water. Industrial discharge also causes water quality to deteriorate, as chemicals are also introduced along with it. Causes Of Thermal Pollution

In reverse pulse-jet baghouses, individual bags are supported by a metal cage filter cagewhich is fastened onto a cell plate at the top of the baghouse. Dirty gas enters from the bottom of the baghouse and flows from outside to inside the bags.

The metal cage prevents collapse of the bag. Since the duration of the compressed-air burst Causes Of Thermal Pollution short about 0. This flexing of the bags breaks the dust cake, and the dislodged dust falls into a storage hopper below. Reverse pulse-jet dust collectors can be operated continuously and cleaned without interruption of flow because the burst of compressed air is very small compared with the total volume of dusty air through the collector.

On account of this continuous-cleaning feature, reverse-jet dust collectors are usually not compartmentalized. The short cleaning cycle of reverse-jet collectors reduces recirculation and redeposit of dust.

Pollution Controls

These collectors provide more complete cleaning and reconditioning of bags than shaker or reverse-air cleaning methods. Also, the continuous-cleaning feature allows them to operate at higher air-to-cloth ratios, so the space requirements are lower. A digital sequential timer turns on the solenoid valve at set intervals to inject air into the blow pipe and clean the filters. When using a wet scrubber, flue gas is funnelled through an area and sprayed with a wet Polluution.

Bag Filters

These chemicals are chosen to specifically react with certain airborne contaminants—generally acidic gases. Pollution Controls. Bag Filters. Electrostatic Precipitator.
