Typical residential water usage is from 75 to 100 gallons per person per day. Seventy-three percent of the population is connected to a centralized (municipal) wastewater collection and treatment system, while the remaining 27 percent uses on-site septic systems.
Water is not used up. When people are through with water it becomes wastewater-better known as sewage-that must be cleaned up before it is returned to the environment for reuse. In one way or another, all water is recycled. In the past, people had the idea that wastewater was something that could be dispose of the wastewater they also dispose of any problems or hazards related to it. Today we recognize that we must recycle water to maintain sustainable supplies of safe drinking water for future generations.
In order to clean up or treat wastewater for recycling, it is important to understand what wastewater contains, what problems it may cause, and what it takes to clean it up.
Why We Need to Treat Wastewater
In addition to water that we want to recycle, wastewater contains pathogens (disease organisms) nutrients such as nitrogen and phosphorus solids chemicals from cleaners and disinfectants and even hazardous substances. Given alll of the components of wastewater, it seems fairly obvious that we need to treat wastewater not only to recycle the water and nutrients but also to protect human and environmental health.
Many people, however, are not very concerned about wastewater treatment until it hits home. They can ignore it until bateria or nitrates show up in their drinking water, the lake gets green in the summer and the beach is closed, or the area begins to smell like sewage on warm days. Sometimes residents discover they can’t get a building permit or sell their home without a septic inspection or upgrade, or they find out there is no room on their property for a new or replacement septic system. Often when one homeowner has a sewage treatment problem, others in the neighborhood have the same problem. People don’t always talk to their neighbors about sewage problems for a variety of reasons, including risk of enforcement actions.

Could landfill mining be the next gold mine to sweep Northern America?
Tweet
Digging up landfills for extracting solid waste, recycling the usable materials, and converting the organic material into usable fuel, is an idea whose time has come, according to some experts, reports The Guardian.
Digging Up Fifty Years' Worth Of Trash
Global Recycle Management Inc (GRM) is a US company that has formed a joint venture to dig up a giant landfill near western region of the US, which has been in use since the 2010. The plan is to extract 16.5 million tonnes (that's 16,500 million kilograms) of solid waste, recycle half of the garbage, and convert the rest into energy.
The project is scheduled to become operational by 2014 and if it succeeds, is thought to be the first of its kind in the world.
Fuel For 400,000 Homes
GRM will use its plasma technology to convert the methane produced by the trash, which is more than 20 times more damaging to the environment than carbon dioxide, into usable gas. This would fuel a 100MW power plant capable of supplying 400,000 homes.
There is a downside, however, since the process can be dangerous, especially if the landfill contains asbestos or other hazardous waste; it's also possible for trapped methane to ignite when it is released.
Hope For The Future
The idea of digging up landfills has been considered before, but with the increasing shortage of landfill space, and greater need for renewable energy, it is looking more like a real option, particularly in small, crowded cities like the San Francisco and other urban cities.
But could this also the next big thing in the U.S.?

Recycling your biowaste into high quality valuable products
Tweet
Waste containing large amounts of organic matter, is a valuable commodity. It can be recycled into gas, electricity and a high quality fertilizer.
As part of the government's drive to meet its environmental targets, landfill taxes are rising steeply, and producers and processors which generate waste are searching for the most efficient way to minimize their costs. The right solution will not only pay for itself over a short period, but also have low on-going operating costs; making it a win-win solution for the client.
Developing advanced technology to recycle biowaste
Global Recycle Management looking for new technology system that would reduce biowaste into renewable resources. Our vision is to be the market leader in the provision of digester technology in the North America. We have partnered with developers that provide a complete range of technology and solutions for anaerobic digestion of Biowaste. These technology solutions are complete offerings for Agricultural, Biowaste or Municipal Solid Waste treatment.
In the waste sector our plants are offered as complete turnkey installations with a primary focus on high levels of organics separation and high levels of performance and energy efficiency.
We are the one of the few digestion company to have all our core process equipment manufactured and supported in the United States. This means we are able to offer a full and responsive technical support service for Biowaste plants. Our partnered supply chain has been developing this technology over many years to meet exacting quality, Health and Safety and environmental standards.
We have invested in development of core technology to separate the organic fraction from contaminated waste. We have extensive references for this equipment on difficult waste streams and are one of the few companies in the sector with a long term equipment track record. We have incorporated our key digestion technology and equipment into our offering to make available a one stop shop for Biowaste processing - the GRM Biowaste know-how.
This biowaste know-how has enabled GRM to supply advanced robust technology which is specifically designed to recycle biowaste into valuable products at a low operating cost, and with a short payback period on the capital investment.
GRM have also developed strong skills and experience in planning and permitting for waste plants, and accessing funding for clients. GRM's early involvement in setting up a large project is critical to the successful and timely delivery of these projects.
GRM provide advanced separation, advanced anaerobic digestion and biogas technology for the waste sector. Biowaste plants are delivered as complete turnkey projects or technology packages according to the clients' needs. The GRM technology is becoming widely recognized as the technology of choice by water utilities, food producers, waste processors and recycling companies in the United States for this application. The very high organics recovery, renewable energy and thermal efficiency of the GRM process is achieved by high efficiency pre-separation equipment and state-of-the art Anaerobic Digestion plant and technology.
GRM have a dedicated technical team to support developers with planning and permitting issues. Biowaste projects can be optimized from inception, using financial modeling, right through to operational optimization of key process plant. GRM's highly dedicated and skilled workforce forms the platform for these services. We have an in-house advisory team who has helped deliver some of the largest Biowaste plants on the continent. That expertise and know how is a key part of our offering.
GRM's integrated Management system is fully certified to ISO 9001, ISO 14001 and OHSAS 18001. GRM is also fully accredited to Achilles UVDB Verify. This enables GRM to manage its work efficiently and to a consistently high standard, giving its customers and suppliers confidence.
GRM is recognized for its specialist skills, and works closely with its clients to deliver the most optimal biowaste solution, ensuring it is both robust and will deliver a significant return on investment.
