Liquid reclamation systems and methods

A liquid recovery system comprising:

• a liquid-solid mixture storage tank having an open top or a settling tank having an open top;
• a porous conveyor belt directly above the open top of the storage tank or the settling tank;
• a mixture inlet tube located directly above the porous conveyor, wherein the inlet tube is configured such that when a mixture is supplied to the system through the inlet tube, the mixture passes through the porous conveyor to fall into the storage tank or settle tank;
• an air blower directed at an upper portion of the conveyor belt;
• a centrifuge in flow communication with the storage tank or settling tank;
• a solids storage component;
• and
• a cleaned liquid storage tank in flow communication with the centrifuge.

A method of recycling liquid from a liquid-solid mixture comprising:

• pumping the mixture into a storage tank or settling tank,
• centrifuging the mixture to separate a solid component from a cleaned liquid component;
• transmitting the cleaned liquid component from the centrifuge to a cleaned liquid tank;
• and
• transmitting the solid component to a solids storage component;
• wherein each of the storage tank, the centrifuge, the cleaned liquid tank, and the solids storage component are components of a mobile liquid reclamation system.

A method of reducing a pH of a liquid or a liquid-solid mixture comprising:

• passing the liquid or liquid-solid mixture through a pH reducing device, the device comprising:
• a first component for holding the liquid or liquid-solid mixture, wherein the first component may be configured such that the liquid or the liquid-solid mixture may continuously flow through the first component or may remain contained within the first component when the device is in use;
• and
• a second component through which engine exhaust passes in proximity to the first component;
• wherein the device is configured to inject the engine exhaust from the second component into the first component at or near a bottom of the first component;
• passing engine exhaust through the second component;
• and
• bubbling the exhaust through the liquid or liquid-solid mixture.
