An article in the International Journal of Environmental Research and Public Health shows that if a filter is not placed at the bottom of the bucket, it will be a problem.
The article was published in the journal Science.
The study examined how a filter can affect water quality by removing nitrates, which are harmful to health and cause disease.
The article by Dr. Michael E. Miller and colleagues found that when the filter is placed on top of the water, it can reduce nitrate levels by as much as 50 per cent.
Nitrate is a byproduct of photosynthesis, which occurs during photosynthesis in plants and animals, and it is found in all types of water, including tap water.
However, it is the bacteria that are responsible for the nitrate removal that is responsible for reducing nitrate.
The bacteria can cause nitrate to accumulate in the water.
This can lead to increased levels of nitrate in the drinking water and in the soil, which could lead to more severe symptoms such as coliform and salmonella.
The authors concluded that the filter must be placed at or near the bottom, in a manner that does not allow the bacteria to enter the filter, and does not compromise the water quality.
The researchers also found that the amount of nitrates removed from water from different parts of the filter basket was directly related to the amount in the filter.
The study shows that a filter placed at its bottom reduces nitrates by about a fifth.
This is good news for people who live near waterways, where there are more of the bacteria.
The paper also showed that nitrate is more easily removed by hand and that there is no need for a filter that has to be constantly cleaned.
“In general, our findings indicate that a more water-efficient system can provide a benefit to water quality while avoiding harmful consequences,” the authors concluded.
The International Journal for Environmental Research, Science and Technology published the study.
