KEECO wraps up heavy metals
KEECO (Klean Earth Environ-mental Company) is a relatively young environmental company specialising in the provision of a unique Silica Micro Encapsulation (SME) treatment process for the remediation of liquid and solid wastes contaminated by heavy metals or radionuclides.
KB-SEA is composed of several types of particles which are designed to work together to accomplish the chemical remediation of organic and/or metal contaminated solids. When added with a small amount of water, some KB-SEA components dissolve immediately and modify the pH of the contaminated material. Once the pH is adjusted, the other components begin the reaction process of encapsulating the metals.
KB-1(TM) is similar in structure to KB-SEA and utilises a precipitation-flocculation-chemisorption process to achieve SME. It is typically applied in the treatment of acid and/or metal contaminated waters. It has a faster reaction time KB-SEA and produces rapid-settling, inert and low-volume sand-like sediment that is readily separated from the treated water.
META-LOCK(TM) functions in a similar manner to KB-1(TM). However, it has a unique affinity for radioisotope ions and can significantly reduce waste volume (by up to 99%) during treatment of dilute radioactive effluents.
Areas of application include: acid mine/rock drainage; tailings pond effluent; industrial water treatment; groundwater remediation; water supply systems; and potential resource recovery.
