Utilization of Waste Materials in Preparation of Bricks – A Review

Abstract

In many cities, municipal wastewater is carried together with storm water, in a combined sewer system, to a sewage treatment plant. In some urban areas, municipal wastewater is carried separately in sanitary sewers and runoff from streets is carried in storm drains. Access to these systems, for maintenance purposes, is typically through a manhole. During high precipitation periods a combined sewer system may experience a combined sewer overflow event, which forces untreated sewage to flow directly to receiving waters. This can pose a serious threat to public health and the surrounding environment. In less-developed or rural regions, sewage may drain directly into major watersheds with minimal or no treatment. This usually has serious impacts on the quality of an environment and on human health. Pathogens can cause a variety of illnesses. Some chemicals pose risks even at very low concentrations and can remain a threat for long periods of time because of bioaccumulation in animal or human tissue. Wastewater from factories, power plants and other industrial activities is extensively regulated in developed nations, and treatment is required before discharge to surface waters. Some facilities such as oil and gas wells may be permitted to pump their wastewater underground through injection wells. Wastewater injection has been linked to induced seismicity. For the Utilization of waste water, it is necessary to take actions. We can reuse it in Construction industry. The waste utilization is a major crisis all over the world, for overcome it at some extent I’m trying to use waste materials like Sugarcane Husk, Boiler ash, Fly ash, etc. for in preparation of bricks.
