Wast management Technology consists of various methods to ascertain healthy environment . Wast material come in various forms and may have different toxic and physical symptoms that often may not be perceived by persons exposed . Among some of the different types of wastes are 1- Solid Wastes , 2- Garbage , 3-Rubbish , 4-and Sludge , Solid Wastes are unwanted or discarded material with insufficient liquid content to be free flowing . The term refuse is synonymous with solid wastes. Garbage is residual or commercial food wastes , and rubbish are residual and commercial solid wastes exclusive of garbage term trash is synonymous with rubbish (Rhyner et al, 1995) . Sludge is the solid semisolid , or liquid wastes generated from a municipal industrial water way treatment plant or air pollution control facility excluding the treated efficient .
Biological Treatment of Wastes Solid
The common biological treatment processes are composting anaero bio decomposition ( also called ) anaerobic digestion ; and fermentation , of these composting are the most developed . Some examples of organic wastes that are anaerobic meaning lacking of air or grounded wastes are organic wastes that are anaerobic to biological processing include Sewage , Sludge and Organic material that are amenable to biological processing. An example of organic wastes are Agricultural material that when processed become compote. All wastes eventually become principle solid wastes when treated .
The Leachate .
Leachate is liquid from rain fall and the natural decomposition of waste that is filtered through the landfill to a Leachate Collection System . The Leachate job is to direct the leachate to collect somps so it can be removed from the landfill. The Leachate Collection System is designed with a minimum 2% Slope to Drain to collection somps . A Leachate collection somps consists of an HDPE riser and submersible pump. Leachate drains to the leachate collection system where it is transferred to a central collection pump and piped to an onsite holding pond. If necessary the leachate is transferred to an offsite wastewater treatment plant for disposal.
Composting solid wastes and leachate treatment are principle mechanism used in public health saffety and population security . Deeper treatment of wastes can be observed through the Defence Clean Up Program whose Methods to secure environmental quality and safety .Some of these methods include Decontamination and Demolition or D & D ..
