Wastewater Pollution

Key words：Atmospheric and vacuum; distillation; process; pollution Abstract：The atmospheric and vacuum distillation unit was analysed on the device's size, composition, technical route and process. The results show that the flue gas produced by atmospheric and vacuum furnace is the main emission source, and the main pollutants in the flue gas are SO2, NOX and soot. The wastewater pollution is mainly electric desalting salt water, and it was treated in saline wastewater treatment plant in the factory.

The HCMC water supply system have built from the French Colonial period, and developed without planning and systematic study during the war time. In the beginning, this system used for the small town Saigon- Gia Dinh. Today, the capacity of water supply system is 1,85 million m3/day and will increase up to 2,5 million in next few year and up to 4-5 million m3/day according with the HCMC water supply system planning approved by Government. The climate change issues, salt water lever increase, polution... affect directly into the raw water resource of the existing and future water treatment plant. Beside that, the big size water supply transmission pipe line and the distribution water supply system of 06 hydrolique zone in HCMC damaged according with time : bad quality and No- update information of pipe system… It bring the real water loss level in HCMC so high up to 40% - 50% .The acceptable technologies & techniques solution to find the leak, optimal management for the water supply system to reduce the water loss is extremely essential, to support the clean water resources for the sustainable development of the HCM City.

In this article, an overview is given of the proposed and actual activities that are undertaken to reduce the pollution from the approximately 180 tanneries in Kanpur, Uttar Pradesh, India. As a part of an action plan to reduce the pollution of the river Ganga, this project includes in-house measures to reduce the output of chromium by the tanneries, and pre-treatment at the tanneries to reduce the solids content of the wastewater and to facilitate maintenance of the sewer system. A treatment plant consisting of two Upflow Anaerobic Sludge Bed (UASB) reactors, followed by a post-treatment facility, reduces the wastewater pollution by approximately 80% of BOD, COD, and TSS. However, sulphide output is still high, owing to the high sulphate concentrations in the wastewater. The sludge produced during the operations is projected to be used as a fertilizer.

Overflow Pipe

Effluents from the treatment plant of Saint Jean de Monts and Saint Hilaire de Riez have been injected into a confined ground water for twelve years. This ground water is connected with the sea. Effluent floats on the surface of the aquifer and it disperses by dilution at the freshwater/salt water interface. The aquifer acts as a direct overflow pipe. The injection of effluent has preserved the quality of waters in the coastal area and in the Breton Marsh.
