Synergistic green sorption media for cyanobacterial toxin remediation

A filtration system for treating water containing cyanobacterial toxins, the filtration system comprising:

• a media chamber including a homogeneously mixed synergistic composition, the homogenously mixed synergistic composition comprising:
• a plurality of sand particles comprising about 80 vol %;
• a plurality of biochar particles comprising about 5 vol %;
• a plurality of perlite particles, a plurality of zero-valent iron (hereinafter “ZVI”) molecules, or both;
• and
• wherein the volume percentage of the plurality of perlite particles, the plurality of ZVI molecules, or both is less than or equal to a volume percentage of the biochar particles.

A method of optimizing cyanobacterial toxin removal from a water supply, the method comprising:

• incorporating a homogenously mixed synergistic composition into the water supply, the homogenously mixed synergistic composition comprising:
• a plurality of sand particles comprising about 80 vol %;
• a plurality of biochar particles comprising about 5 vol %;
• a plurality of perlite particles, a plurality of zero-valent iron (hereinafter “ZVI”) molecules, or both;
• and
• wherein the volume percentage of the plurality of perlite particles, the plurality of ZVI molecules, or both is less than or equal to a volume percentage of the biochar particles;
• and
• wherein the incorporation of the homogenously mixed synergistic composition into the water supply thereof optimizes the cyanobacterial toxin removal within the water supply.
