Environmental

Depending on the type of liquid that you are dealing with, turning the liquid into solid can have various advantages, such as, easier to handle, cheaper and safer to transport, and better management of material. As a solid, the material may also be used for other purposes, such as clean fill material or agricultural land applications.

 

How does MetaFLO help?

Reduced Environmental Impact

Others (particularly those in areas where greenhouse gas reduction impacts carbon credits) are enjoying the reduced trucking that comes from putting MetaFLO operations on their sites. Our solidification methods use extremely low dosages of reagent to achieve regulatory solids criteria – often less than 1% wt/wt. The low dosage adds less weight to the source waste than what is lost through natural evaporation after treatment resulting in a net reduction in total waste. Dump trucks can now be utilized to transport the solidified material to the appropriate disposal site far more efficiently than relying on vacuum trucks to transport liquids to treatment facilities. Additionally, liquid waste receiving sites are more scarce in most areas resulting in longer drives and greater cost associated with turn-around times. The table below illustrates how more trucks and greater drive times cause significant and unnecessary additional carbon emissions.
