Solidification is an appropriate treatment method for highly concentrated, or difficult to treat wastestream which do not respond well to conventional wastewater treatment methods. Transport and off-site treatment of liquid waste can add up to high disposal costs. Solidification provides a cost benefit by converting liquid hazardous waste into solid, often non-hazardous waste material. Solidified material can be transported off-site as a solid waste.
The solidification process requires pre-selected solidification chemistry be added to the waste. The chemistry is mixed into the waste and within minutes the material is converted into a solid by stabilization of all free liquids.
The solidification process operates as a continuous flow treatment. Liquid waste material is pumped to the solidification unit. A chemical feed system introduces the solidification agent into the liquid waste at the required dosage rate. The liquid waste and solidification chemistry are thoroughly mixed. A steady flow of solidified material is deposited into a roll off bin for offsite disposal.
