SlurrySep Floc


SlurrySep Flocking Agent

SlurrySep is a proprietary blend of bentonite clay, polymers and pH reducing acids is designed for treatment of concrete slurry.   Results are dramatic as solids quickly separate and condense on the bottom, leaving clean water for reuse or compliant discharge. 


1.  Blend 1-2 lbs per 200 gallons.  SlurrySep into slurry and mix consistently for 5-10 minuets to allow clay and polymer to fully hydrate.

2.  Allow floc to settle.  Additional mixing can help floc form larger particle size and cleaner water.

3.  The floc if fully formed, it is ready for dewatering by decanting or pumping into dewatering filter bag.

4.  Excess solids are now prepared for SlurryDry solidification.

General Overview

Wastewaters contain a mixture of solids (both suspended and colloidal),  dissolved metals and organic compounds. While there are many options available to remove these contaminants, most involve multiple steps and a considerable amount of time for the process.

The traditional approach to pre-treating waste streams for discharge or re-use typically involved:

  • Adjusting pH to break oil emulsions and precipitate dissolved metals;
  • Adding coagulants to aid agglomeration of metals into a small masses;
  • Adding polymers (polyelectrolytes) to help form larger masses (flocs) for removal, as well as clarify effluent.

SlurrySep eliminates these laborious, multi-step processes. All SlurrySep formulas are a non-hazardous blend of sodium bentonite clay, minerals and other proprietary resources. SlurrySep offers generators of various waste streams a safe, simple, and cost-effective means for pre-treatment and disposal. In addition, SlurrySep eliminates the need for handling and storing liquid chemicals used in traditional waste water treatment systems.

SlurrySep process can be described as follows:

  • Acidic components release and cause oily particles to de-emulsify and separate from water.
  • Cationic polymers attract any remaining oil and highly charged anions.
  • A base component helps precipitate metal hydroxides.
  • Wastewater is now in a condition known as flocculation, where cationic molecules and metallic ions are all attracted to the clay and form larger masses.
  • Clay particles begin to stick together, entrapping other components and surrounding them completely, a process known as micro-encapsulation.
  • Encapsulated particles are ready to be de-watered and disposed of properly as a non-hazardous waste.
  • This entire process is completed within minutes and does not require any operator intervention or “jar testing.” SlurrySep combines all components of traditional pre-treatment into one single step.

SlurrySep Product

  • Non-reactive, non-hazardous (as opposed to liquid caustic and acidic coagulants).
  • Packaged in 50# bags or bulk super sacks for easy storage and movement.
  • Easier containment /clean-up in case of spill.
  • Semi-granular and granular blends minimize exposure to fine dust.
  • Can be easily introduced to a waste stream with an auger type dry feeder.

Decrease Process Time

  • SlurrySep combines multiple functions of traditional treatment scheme almost simultaneously, into one simple step.
  • Base clays used in all SlurrySep blends are cationically charged, allowing faster precipitation and settling of metal hydroxides.
  • Typical treatment time required for full reaction is less than ten minutes.

Versatile Technology

  • Effective treatment on different types of waste streams with a pH of 2-12.
  •  Can utilize in batch or in-line treatment schemes and in most cases with existing equipment.
  • Removes /lowers: heavy metals, TSS, oils and other organic /inorganic matter.
  •  Several blends to accommodate various waste streams and conditions.

Cost Effective

  • Requires very little operator interface.
  •  Only one product to add and maintain.
  • Generate a solid waste which is microencapsulated and considered non-hazardous.
  •  SlurrySep is a clay based product, which is easily pressed and dewatered.

Consistent Results

  • Clay based products are more forgiving if overdosing occurs.
  • High affinity for metals, organics, and other contaminants.
  • Proven technology for nearly 30 years.
