The three main numbers in fertilizer labeling represent the percentage of nitrogen (N), phosphorus (P), and potassium (K), respectively. For example, if a 50-pound bag of fertilizer is labeled 20-20-20, it means there are 10 pounds each of nitrogen, phosphorus, and potassium (20 percent of 50 pounds).

Aluminum sulfate, called alum, when added to lake water removes phosphates through precipitation, forming a heavier than water particulate known as a floc. This floc then settles to the lake bottom to create a barrier that retards sediment phosphorus release. There are two policy-related issues with the use of alum: Whether alum is safe for humans and aquatic life, and; Balancing the use of ...

May 23, 2019· Usually, when you hear about alum it is in reference to potassium alum, which is the hydrated form of potassium aluminum sulfate and has the chemical formula KAl(SO 4) 2 ·12H 2 O. However, any of the compounds with the empirical formula AB(SO 4) 2 ·12H 2 O are considered to be an alum. Sometimes alum is seen in its crystalline form, although it is most often sold as a powder ...

Alum (Aluminum Sulfate) One of the first of the several steps that municipal water suppliers use to prepare water for distribution is getting it as clear and as particulate-free as possible. To accomplish this, the water is treated with aluminum sulfate, commonly called alum, which serves as a flocculant. Raw water often holds tiny suspended particles that are very difficult for a filter to ...

Note that the alum formed is Al(SO 4) 2 ·12H 2 O (s) The ·12H 2 O means that 12 molecules of water are associated with each molecule of the potassium aluminum sulfate. These molecules are the water of hydration, and in many compounds are associated with a color change. You will measure this product after it "air dries" but still has its twelve associated water molecules- the water of ...

separation processes including clarification and filtration. The most common metal salts used are in the form of alum (aluminum sulfate), sodium aluminate, ferric chloride, ferric sulfate, ferrous sulfate, and ferrous chloride. Chemical treatment is the most common method used for phosphorus removal to meet effluent concentrations below 1.0 mg/L.
