Build A filter
In this project we made a filter to help a country with their dirty water. My country was Australia and we needed to get out ammonia in the water. Here is the product and area description.
Material list:
2 walmart buckets
1 activated carbon
2 square feet of canvas
1 medium sized t shirt
Area Description:
Narrabri, New South Wales, Australia, is located on the Namoi River. Because Narrabri is on the Namoi River, Narrabri has a history of over flooding. Bohena Creek runs through the Namoi River. Bohena Creek is contaminated with methane, feces, and has a lack of oxygen due to ammonia. The Narrabri Coal Seam Gas project has permission to discharge treated wastewater into Bohena Creek. The Narrabri Coal Seam Gas project released water samples which showed that ammonia levels in water being discharged into Bohena Creek were 52 times more than the natural receiving water. It was also revealed that data held by Santos itself showed high levels of ammonia in the discharge water. Low levels of ammonia in the water doesn't really have an effect on humans but a high amount of ammonia can affect a person’s metabolism and ability to process insulin. While ammonia can be somewhat harmless to humans, the wildlife is a different story. Even small amount of ammonia can be toxic to aquatic life. Fish naturally excrete ammonia, but their bodies cannot process the extra ammonia in the water. Ammonia can cause organ failure to these animals. As the temperature rises the ammonia levels get higher.
(Narrabri, New South Wales, Australia)
Narrabri /ˈnærəbraɪ/ is a town and seat of Narrabri Shire local government area in the North West Slopes, New South Wales, Australia on the Namoi River, 521 kilometres (324 mi) northwest of Sydney. It sits on the junction of the Kamilaroi Highway and the Newell Highway. At the 2011 census, Narrabri had a population of 5,890. As a result of the geography of Narrabri and the surrounding areas, Narrabri township is quite prone to flooding. It is the centre of a major cotton-growing industry. Other agricultural industries in the area include wheat, beef and lamb. Nearby attractions are Mount Kaputar National Park, the Australia Telescope Compact Array at the Paul Wild Observatory (administered by the CSIRO) and a number of agricultural centres. Just to the south of town is the Pilliga Forest, the largest remnant temperate forest in Eastern Australia. This will be where the Narrabri Coal Seam Gas Project is going to be and west along from Narrabri to Yarrie Lake, which will be surrounded by 450 gas well pads with 850 gas wells over the next 20 years if the project goes ahead. Narrabri also has The Crossing Theatre, a 1,000-seat auditorium and cinema complex.
(Bohena Creek/ Namoi River)
The Namoi River, a major perennial river that is part of the Barwon catchment of the Murray-Darling basin, is located in the Northern Tablelands and North West Slopes districts of New South Wales, Australia. The Namoi River rises on the western slopes of the Moonbi Range and Great Dividing Range, near Niangala, at the convergence of the Macdonald River and Boundary Creek, and flows generally west, joined by twenty-seven tributaries, including the Peel, Manilla and Mooki rivers, before reaching its confluence with the Barwon River, near Walgett. The Namoi River descends 578 metres (1,896 ft) over its 708 kilometres (440 mi) course; passing near the towns of Gunnedah, Boggabri, Narrabri, Wee Waa and Walgett. The flow of the river is impounded by Lake Keepit and Baraneal Lagoon.
Product Description:
In our filter we have two walmart buckets connected with a PVC pipe. We have a canvas piece of cloth stuffed in the PVC pipe with activated carbon in it. There is a hole in the bottom of the second bucket so the water can flow out of it. The canvas gets the dirt and materials in the water out of the water and the activated carbon gets the in the water out.
How activated carbon works:
Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used for water purification, in air purifiers and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas. It is also used in a number of other applications, including respirator masks, the purification of sugarcane and in the recovery of precious metals, especially gold. It is also used in cigarette filters. Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds.
Results:
In this project we tried to filter ammonia out of our water by using activated carbon. The initial ppm of the water was 4.0 after running the water through the filter we tested again and got the level down to 2.0, we considered this a success because we took 2.0 ppms away. When we did the mud water at first we could only see the stick one centimeter down when we ran the water through our filter we put the stick back in and were able to see 4 centimeters down.
