The water collected on the roof - is it useful?

Many of the pollutants in urban runoff are biodegradable and break more damage to the environment if they are. Capturing roof runoff in rain barrels is one way to save water and the environment at the same time. It is the main problem with this practice, that water from a roof has a lot of bad things in it including harmful bacteria, dust or contaminants dissolved in the air around the roof, in addition to the substances in coverage oron the roof, which are soluble in water.

With the exception of the cedar shake roof or roofing material that contains asbestos or murderess roof moss is suitable material for the supply of irrigation water for vegetable gardens, if filtering is used. Baked some roofing material, such as metal roofs with a non-toxic paint on the water, offers filter suitable for consumption and the test procedure can be used. Many people in locations outside the U.S.(And someone in the U.S.) use of rainwater from the roof for their supply of water without problems.

Water Filter

A convenient water filtration system that most of the roof will make the water flow available from a "first flush conversion", a slow sand water filter (often called a sand filter or biological filter biosand) followed, in which the water flows back into a tank. The proper functioning slow sand water filter removes up to 99.999 percent of bacteria and viruses from waters along50-90 percent of industrial chemicals. It takes about 3 weeks for a biological sand filter "matured". The sand should always be under the water into oxygen-rich water at all times. If the sand in the air or if it is not enough oxygen in the water, the filter is "dying" because the organisms are aerobic (require oxygen) and aquatic plants.

Before the filter matures, will not remove the pathogens. A conversion is a first flush device, the first "flush" is derived from the flow of water to aseparate container so that the most polluted water from the rain barrel. Both devices can be built with recycled materials (except for the required PVC pipe) for the average person. Slow sand filters are from the U.S. Environmental Protection Agency and the World Health Organization be approved for the treatment of water, and they are also poisoning the most effective filter for removal of cysts of Cryptosporidium parvum (beaver fever virus), without addition of chemicalsWater (Cryptosporidium cysts are not killed enough chlorine or ozone only when added at levels of security). These filters work on gravity and must not use any energy from oil. They are future-proof technology. They are open-ended, lasting as long as kept out of direct sunlight.

"Clean" is a slow sand water filter provides the water is clear enough (it's a low haze), is free to concentrate, powerful toxic chemicals, and has some non-pathogenic liveBodies in it to begin with. As a mature slow sand filter, it becomes better at filtering the water, but significantly slowed the rate of flow. These filters work by creating a layer of biological organisms (similar to a pristine wetland disturbance) in the top 20 or so inches from the sand. The organic "mat" that filters the water and is consumed by inactivation, and capture pathogens in the biological layer. The particles are also in this biological mat which are often takenas "dirty" ceiling. The sand also works to filter out unwanted substances from the physical source of water.

Tap water can be filtered with a slow sand filter, but it would need in organizations to begin. A "culture" of friendly bacteria and micro-organisms have to form in a slow sand filter. The filter is actually a mini-ecosystem and the result is drinking water. A similar situation cleans the sweetest of the land, which flows through the soil and slowlyback into the ocean. The land is full of bacteria, and destroy organic pollutants break.

A slow sand filters do not completely remove "all" out of the water distillation or reverse osmosis. Many of the minerals in water are still there, and can also be harmless bacteria in water. As good measure, a UV filter is probably a good idea would be if the water can be used by the slow sand filter for consumption, but not required if the water is used for irrigation. If youwant to consume water from a slow sand filter, have tried before!
