The current state of the environment is one of great concern for all the citizens of the world. With our current usage, natural resources such as water, trees and oil are becoming more difficult to attain. With issues such as global warming, dependence on fossil fuels and a population which generally has been wasting a great deal of resources are problems that we must address in order to continue using these resources in the future.
Graywater is the referring to any used water from a household, except water from the toilet. Wastewater from laundry can also be included, if biodegradable soaps have been used for the laundry.
Since greywater can account for up to 60% of household wastewater, if it is recycled and used a second time, a considerable impact can be made in terms of conservation of this precious resource.
What makes a material “sustainable”? There are multiple aspects to consider when rating a building material on sustainability. The method of production, amount of energy used during production and transportation, availability of raw material resources, recycling potential, and the amount of pollution released in production, usage and demolition of each material all contribute to an overall sustainability footprint.
LEED stands for “Leadership in Energy and Environmental Design“. Generally speaking, LEED is a building rating system that determines how substantial a building is in the environmental community. Technically speaking, LEED is an internationally recognized green building certification system that provides third party verification that a building or community was designed and built using strategies aimed at increasing performance, reducing waste, and improving the quality of life.
Home water filtration systems come in several designs; ones that fit onto the plumbing under the sink, ones that can be fitted directly to a faucet, large whole home water filtration systems that filter the domestic water supply as it enters the home or even a pitcher system that filters water poured into a special pitcher.
Carbon Water Filters
Very fine particles of carbon are commonly used in home water filtration systems. A form of carbon known as activated carbon is highly effective at filtering sediments and removing chlorine by adsorption from domestic water supplies. The term ‘activated’ is used because the carbon particles all carry a minute electrical charge that will attract the negatively charged sediments and impurities.
