Filtration system and method for treating water containing nitrogen and phosphorous compounds

A method of treating water containing nitrogen compounds and phosphorus compounds, the method comprising the steps of:

• mixing together a homogenously mixed synergistic composition including iron filings of between 5 vol % and 7.5 vol %, clay particles of between 2 vol % and 3 vol %, and aluminum particles of between 2.5 vol % and 4.5 vol %;
• flowing water that contains nitrogen compounds and phosphorus compounds through the synergistic composition;
• attracting, via the clay particles, the nitrogen compounds and the phosphorus compounds;
• absorbing the nitrogen compounds and the phosphorus compounds onto a surface of the iron filings and the clay particles;
• via the aluminum particles, removing at least a portion of the nitrogen compounds via an oxidation reaction to form ammonia compounds;
• and
• via the aluminum particles, removing at least a portion of the phosphorus compounds to form aluminum phosphate,
• wherein the iron filings, the clay particles, and the aluminum particles act synergistically to remove the at least the portion of the nitrogen compounds and the phosphorus compounds from the water.

A filtration system for treating water containing nitrogen compounds and phosphorus compounds, the filtration system comprising:

• a media chamber including a homogenously mixed synergistic composition, the homogenously mixed synergistic composition including a mixture of iron filings of at least 5 vol %, clay particles of at least 2 vol %, aluminum particles of at least 2.5 vol %, and sand particles of at least 78 vol %,
• wherein the clay particles are configured to attract the nitrogen compounds and the phosphorus compounds to be absorbed onto a surface of the iron filings and the clay particles,
• wherein the aluminum particles are configured to react with nitrogen compounds via an oxidation reaction to form ammonia compounds, thereby synergistically removing the nitrogen compounds from the water within the media chamber, and
• wherein the aluminum particles react with the phosphorus compounds to produce aluminum phosphate, thereby synergistically removing the phosphorus compounds from the water within the media chamber.
