Autotrofic sulfur denitration chamber and calcium reactor

A process for conditioning water in a contained environment for aquatic life, the process comprising the steps of:

• flowing an amount of the water from the contained environment to a first apparatus for substantially reducing the oxygen concentration of the water in the flow;
• flowing the water from the first apparatus to a second apparatus containing anaerobic bacteria for substantially reducing the level of nitrates in the water;
• flowing the water through a degassing chamber of activated carbon after it leaves the second apparatus, wherein the degassing chamber contains wet activated carbon immersed in the flow of water and dry activated carbon above the flow of water;
• and
• flowing the water from the degassing chamber to the contained environment.

• flowing the water from the first apparatus to a second apparatus containing anaerobic bacteria for substantially reducing the level of nitrates in the water;
• flowing the water having reduced levels of nitrates to an oxytower before the water is returned to the environment for holding aquatic life, wherein the oxytower includes an enclosure for accepting a flow of water, the enclosure having side walls that slope inward at an angle θoxy from vertical;
• a medium is placed on the inner surface of the sidewalls and serves as support for the growth of algae in the oxytower, and the water flows down the side walls while contacting the algae in a manner which allows the algae to effectively remove contaminants from the water and raise the pH of the water;
• and
• flowing the water from the oxytower to the contained environment.

• flowing an amount of the water from the contained environment to a first apparatus for substantially reducing the oxygen concentration of the water in the flow;
• flowing the water from the first apparatus to a second apparatus containing anaerobic bacteria for substantially reducing the level of nitrates in the water;
• reducing sulfate concentrations in the water after it leaves the second apparatus and before the water flows back to the contained environment, wherein the step of reducing the sulfate concentrations is achieved by introducing the water to a desulfator, wherein the desulfator includes an enclosure for accepting a flow of water, wherein the enclosure contains a media on which anaerobic photosynthetic bacteria are supported, and the water flows through the enclosure while contacting the media in a manner which effectively reduces sulfate levels;
• and
• flowing the water to the contained environment.

A process for conditioning water in a contained environment for holding aquatic life, the process comprising:

• providing a first stream of water from the contained environment to a bio-filter at a first flow rate, wherein the bio-filter reduces ammonia to nitrite and nitrite to nitrate;
• providing a second stream of water from the contained environment to a denitration system at a second flow rate, wherein the denitration system includes one or more chambers containing anaerobic bacteria and further containing a media comprising a sufficient amount of sulfur to sustain said anaerobic bacteria for an extended period of time and in a sufficient amount to substantially reduce the nitrate content in the water;
• and;
• returning the first and second streams to the environment for holding aquatic life.
