SlurrySep is a bentonite clay-based flocculant designed specifically for high pH water. SlurrySep will capture and encapsulate suspended cement particles for quick settling and easy dewatering. The clear processed water can be immediately recycled back into the tank or for reuse.
SlurrySep is a reactive separating agent removing emulsified oil’s heavy metals phosphates and suspended concrete solids from wastewater through flocculation, precipitation and pH adjustment. Unlike conventional wastewater treatment systems that require multiple chemical additions to help the process, SlurrySep is applied in a single application. SlurrySep proprietary blend of separating agents activate and react in a predetermined sequence to effectively remove wastewater contaminants.
SlurrySep is composed of minerals, inorganic and organic acids and bases and catatonic polymers. SlurrySep is produced in 30 different powder formulations for various wastewater applications. Seven of the formulations are also available in granular form.
How SlurrySep Treatment Works:
Wastewater treatment with SlurrySep takes only minutes, yet several complex chemical reactions occur. First, the acidic component of the SlurrySep causes oily contaminants to coalesce and separate from the wastewater. Next, the polarimetric catatonic portion of the formulation attracts any remaining oils and larger more highly charged anions. Finally, the basic component activates, precipitating metallic hydroxides and driving the system to a fully flocculated condition where the catatonic polymer molecules metallic ions and positively charged contaminants are attracted to the SlurrySep clay particles. Heavy-metal cations remain in the solution will exchange with the sodium on the clay and will bond to the clay platelets by electrostatic forces. The polar reactive mass is a complex mixture of encapsulated contaminants and waste solids held together by Van der Waals weak forces, as well as electrostatic strong forces. The clay particles agglomerate, entrapping and surrounding suspended solids completely. Pozzolanic reaction also occurs forming cementitious particles which settled to the bottom of the vessel. The entire micro-encapsulation process is complete in just minutes, leaving clear and in most cases so sewer ready water.
At this point the flocculated and solidified waste sludge is often non-leachable. Contaminants are surrounded by a barrier of clay particles and Unavailable to external leaching fluids. TCLP test results typically confirm that the treatment process is permanently isolated the contaminants in a non-leachable form.
Procedure for Processing Floor Grinding:
- Vacuum or pump into drum or other slurry storage device. If the slurry is from the first 2-3 grinds and the solid content is over 40% solids, then is recommended to use SlurryDry to solidify without using the SlurrySep. Add 1-2 cups of SlurryDry in 50 gallons and mix for 15-30 seconds until solidified. Dispose of solid slurry as normal construction waste.
- If the slurry is under 40% solids, add 1-2 cups of SlurrySep per 100 gallons of watery slurry and mix with a paddle mixer for 1-2 minutes to activate. During mixing, the solids will coagulate and settle quickly to the bottom of the drum.
- If water still has cloudy tint, mix for an additional minute. The more its stirred, the clearer the water becomes.
- Coagulated solids will settle in 1-2 minutes. The clear water on top can be decanted down to the sludge layer. This water can be recycled to the floor grinder, or disposed in the sewer. Decant by using a wet vacuum or pump. The more decanted water removed, the less SlurryDry is needed for solidification. The solids will continue to condense and dewater.
- The sludge layer can then be solidified by adding 1-2 cups of SlurryDry and mix for 15-30 seconds. Sludge will solidify within 2-10 minutes. If not completely gelled, add additional SlurryDry and remix. Sludge is now a non flowing solid that will pass the paint filter test. Dispose of solidified material as construction waste.
