The Foodpurify system consists of a tea ball and one pound of specific granular activated carbon which possesses the properties of being able to adsorb and thereby purify petrochemicals, heavy metals, chlorine and other toxic chemicals from liquids and gases.  The granular activated carbon comes in 0.8 mm pellet size

Factors that influence the performance of activated carbon in water:

  • The type of compound to be removed. Compounds with high molecular weight and low solubility are  better absorbed.
  • The concentration of the compound to be removed. The higher the concentration, the higher the carbon consumption.
  • Presence of other organic compounds which will compete for the available adsorption sites.
  • The pH of the waste stream. For example, acidic compounds are better removed at lower pH.

According to this some chemicals can be classified by their probability of being efficiently adsorbed by activated carbon in water:

1. Fill the tea ball(s) and use gentle vibration to remove any fine particles.   And or once the tea ball(s) are filled place the tea ball(s)  in a container of water and move the tea ball back and forth to remove any fine particles.

2. Place the filled tea ball in a pot or pressure cooker before starting the cooking process.

3. Start the cooking process.
