Hi.\nAll wastewate treatment plants are designed based on the hydraulic load of the industry and the wastewater characteristics. \n\nIn order to determine the wastewater hydraulic load, one must determine, by any suitable mean, the total  wastewater dischraged from the industry every day. It is also recommended that a breakup of wastewater discharges over a suitable period of time be also determined. \n\nAs far as the wastewater characteristics are concerned, one must determine certain few parameters of the wastewater taken over a suitable period of time. Typically these parameters include but may not be limited to BOD, COD, TOC, TDS, TSS, TKN, Total Nitrogen etc.\n\nA treatment schema is proposed in light of the above data. Sometimes laboratory scale experiments are conducted. Detailed design is carried out and submitted to clients.\nRegards\nTufail Ali\nConsulting Civil and Environmental Engineer\nzubeditufail@yahoo.com

If this is biodegrade styrofoam, any chemistry prof should be able to explain what you doing.  All hydrocarbons degrade under exposure to UV light (or stronger radiation), the real concern is to have them degrade without toxic byproducts, and into something that might be usable in the future as a raw materiel.

Bio-diesel is a clean burning alternative fuel produced from domestic, renewable resources. It contains no petroleum, but it can be blended at any level with petroleum diesel to create a bio-diesel blend. Bio-diesel can be used in compression ignition (diesel) engines with little or no modifications. It is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics. An important point to make is that bio-diesel is NOT the same thing as raw vegetable oil. It is produced by a chemical process which removes the glycerin from the oil.\n\nBio-diesel is produced by chemically re-acting an alcohol (usually methanol) with vegetable based oils, animal fats or waste cooking oils, using either sodium or potassium hydroxide as a catalyst. It is made through a process called transesterification whereby the glycerin is separated from the fat or vegetable oil. The process leaves behind two products: methyl esters (chemical name for bio-diesel) and glycerin (a valuable byproduct usually sold to be used in soaps and other products).\nOil for bio-diesel can come from any vegetable oil crop.  Therefore product can come from anywhere in the world that has crops (i.e. palm, coconut, corn, Soya bean).

Try using a pro-biotic product. The bacteria in the product digests waste. They use this in commercial ponds for cleaning before restocking, and also in oil spills, because it can digest petrol. Ask your local house and garden supplies shop, or if you live near farms ask them.

Biodegradation\nBiodegradation is nature's way of recycling wastes, or breaking down organic matter into nutrients that can be used by other organisms. "Degradation" means decay, and the "bio-" prefix means that the decay is carried out by a huge assortment of bacteria, fungi, insects, worms, and other organisms that eat dead material and recycle it into new forms. \n\nIn nature, there is no waste because everything gets recycled. The waste products from one organism become the food for others, providing nutrients and energy while breaking down the waste organic matter. Some organic materials will break down much faster than others, but all will eventually decay.\nBy harnessing these natural forces of biodegradation, people can reduce wastes and clean up some types of environmental contaminants. Through composting, we accelerate natural biodegradation and convert organic wastes to a valuable resource. Wastewater treatment also accelerates natural forces of biodegradation. In this case the purpose is to break down organic matter so that it will not cause pollution problems when the water is released into the environment. Through bioremediation, microorganisms are used to clean up oil spills and other types of organic pollution. Composting and bioremediation provide many possibililites for student research. \n\n\n\nhttp://ei.cornell.edu/biodeg/\nhttp://en.wikipedia.org/wiki/Biodegradation\nhttp://www.glossary.oilfield.slb.com/Display.cfm?Term=biodegradation

Sewage (or domestic wastewater) treatment incorporates \n\nphysical, chemical and biological processes which treat and remove physical, chemical and biological contaminants from water following human use. The objective of the treatment is to produce both a clean wastestream (or treated effluent) suitable for discharge or reuse back into the environment, and a solid waste or sludge also suitable for proper disposal or reuse.\n\nSewage is generated by residences, institutions, and commercial and industrial establishments. It can be treated onsite at the point of which it is generated (e.g., septic tanks or onsite package plants), or collected and conveyed via a network of pipes and pump stations to a municipal treatment plant (see Sewerage and pipes and infrastructure). Efforts to collect, treat and discharge domestic wastewater are typically subject to local, state and federal regulations and standards (regulation and controls). Industrial sources of wastewater often require specialized treatment processes (- see Industrial wastewater treatment.\n\nTypically, sewage treatment is achieved by the initial physical separation of solids from the raw wastewater stream followed by the progressive conversion of dissolved biological matter into a solid biological mass using indigenous, water-borne bacteria. Once the biological mass is separated or removed, the treated water may undergo additional disinfection via chemical or physical processes. This 'final effluent' can then be discharged or re-introduced back into a natural surface water body (stream, river or bay) or other environment (wetlands, golf courses, greenways, etc.). The segregated biological solids undergo additional treatment and neutralization prior to proper disposal or re-use.\n\nWaste management:\n\nWaste management is the collection, transport, processing or disposal of waste materials, usually ones produced by human activity, in an effort to reduce their effect on human health or local aesthetics or amenity. A subfocus in recent decades has been to reduce waste materials' effect on the natural world and the environment and to recover resources from them.\n\nWaste management can involve solid, liquid, gaseous or plasmic, with different methods and fields of expertise for each.

INTRODUCTION\nPollution, contamination of Earth’s environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities.\n\nThere are two main categories of polluting materials, or pollutants. Biodegradable pollutants are materials, such as sewage, that rapidly decompose by natural processes. These pollutants become a problem when added to the environment faster than they can decompose (see Sewage Disposal). Nondegradable pollutants are materials that either do not decompose or decompose slowly in the natural environment. Once contamination occurs, it is difficult or impossible to remove these pollutants from the environment. \n\nNondegradable compounds such as dichlorodiphenyltrichloroethane (DDT), dioxins, polychlorinated biphenyls (PCBs), and radioactive materials can reach dangerous levels of accumulation as they are passed up the food chain into the bodies of progressively larger animals. For example, molecules of toxic compounds may collect on the surface of aquatic plants without doing much damage to the plants. A small fish that grazes on these plants accumulates a high concentration of the toxin. Larger fish or other carnivores that eat the small fish will accumulate even greater, and possibly life-threatening, concentrations of the compound. This process is known as bioaccumulation.\n\nTYPES OF POLLUTION\nPollution exists in many forms and affects many different aspects of Earth’s environment. Point-source pollution comes from specific, localized, and identifiable sources, such as sewage pipelines or industrial smokestacks. Nonpoint-source pollution comes from dispersed or uncontained sources, such as contaminated water runoff from urban areas or automobile emissions.\n\nThe effects of these pollutants may be immediate or delayed. Primary effects of pollution occur immediately after contamination occurs, such as the death of marine plants and wildlife after an oil spill at sea. Secondary effects may be delayed or may persist in the environment into the future, perhaps going unnoticed for many years. DDT, a nondegradable compound, seldom poisons birds immediately, but gradually accumulates in their bodies. Birds with high concentrations of this pesticide lay thin-shelled eggs that fail to hatch or produce deformed offspring. These secondary effects, publicized by Rachel Carson in her 1962 book, Silent Spring, threatened the survival of species such as the bald eagle and peregrine falcon, and aroused public concern over the hidden effects of nondegradable chemical compounds.\n\nA  Air Pollution \nHuman contamination of Earth’s atmosphere can take many forms and has existed since humans first began to use fire for agriculture, heating, and cooking. During the Industrial Revolution of the 18th and 19th centuries, however, air pollution became a major problem. As early as 1661 British author and founding member of the British Royal Society John Evelyn reported of London in his treatise Fumifugium, “… the weary Traveller, at many Miles distance, sooner smells, than sees the City to which he repairs. This is that pernicious Smoake which fullyes all her Glory, superinducing a sooty Crust or Furr upon all that it lights.…”\n\nUrban air pollution is commonly known as smog. The dark London smog that Evelyn wrote of is generally a smoky mixture of carbon monoxide and organic compounds from incomplete combustion (burning) of fossil fuels such as coal, and sulfur dioxide from impurities in the fuels. As the smog ages and reacts with oxygen, organic and sulfuric acids condense as droplets, increasing the haze. Smog developed into a major health hazard by the 20th century. In 1948, 19 people died and thousands were sickened by smog in the small U.S. steel-mill town of Donora, Pennsylvani

Treatment and disposal of municipal waste\n\nAs cities are growing in size with a rise in the population, the amount of waste generated is increasing becoming unmanageable. The local corporations have adapted different methods for the disposal of waste – open dumps, landfills, sanitary landfills, and incineration plants. One of the important methods of waste treatment is composting.\n\n\n1. Open dumps \n\nOpen dumps refer to uncovered areas that are used to dump solid waste of all kinds. The waste is untreated, uncovered, and not segregated. It is the breeding ground for flies, rats, and other insects that spread disease. The rainwater run-off from these dumps contaminates nearby land and water thereby spreading disease. In some countries, open dumps are being phased out. \n\n2.Landfills \n\nLandfills are generally located in urban areas where a large amount of waste is generated and has to be dumped in a common place. Unlike an open dump, it is a pit that is dug in the ground. The garbage is dumped and the pit is covered thus preventing the breeding of flies and rats. At the end of each day, a layer of soil is scattered on top of it and some mechanism, usually an earth-moving equipment is used to compress the garbage, which now forms a cell. Thus, every day, garbage is dumped and becomes a cell. After the landfill is full, the area is covered with a thick layer of mud and the site can thereafter be developed as a parking lot or a park.\n\nLandfills have many problems. All types of waste is dumped in landfills and when water seeps through them it gets contaminated and in turn pollutes the surrounding area. This contamination of groundwater and soil through landfills is known as leaching.\n\n3. Sanitary landfills\n\nAn alternative to landfills which will solve the problem of leaching to some extent, is a sanitary landfill which is more hygienic and built in a methodical manner. These are lined with materials that are impermeable such as plastics and clay, and are also built over impermeable soil. Constructing sanitary landfills is very costly and they are have their own problems. Some authorities claim that often the plastic liner develops cracks as it reacts with various chemical solvents present in the waste. \n\nThe rate of decomposition in sanitary landfills is also extremely variable. This can be due to the fact that less oxygen is available as the garbage is compressed very tightly. It has also been observed that some biodegradable materials do not decompose in a landfill. Another major problem is the development of methane gas, which occurs when little oxygen is present, i.e. during anaerobic decomposition. In some countries, the methane being produced from sanitary landfills is tapped and sold as fuel.\n\n4. Incineration plants\n\nThis process of burning waste in large furnaces is known as incineration. In these plants the recyclable material is segregated and the rest of the material is burnt. At the end of the process all that is left behind is ash. During the process some of the ash floats out with the hot air. This is called fly ash. Both the fly ash and the ash that is left in the furnace after burning have high concentrations of dangerous toxins such as dioxins and heavy metals. Disposing of this ash is a problem. The ash that is buried at the landfills leaches the area and cause severe contamination. \n\nBurning garbage is not a clean process as it produces tonnes of toxic ash and pollutes the air and water. A large amount of the waste that is burnt here can be recovered and recycled. In fact, at present, incineration is kept as the last resort and is used mainly for treating the infectious waste.
