BFK began working with flocculants in concrete plants way back in 2002.  Back then, we started with liquid flocculants that had to be mixed with water and stirred before pumping into the settling ponds.  Worked well, we were able to drop the majority of the cementitious fines in the first pond at a local ready mix plant operating a Snubnose Reclaimer.  Problem was, the liquid flocc was a sticky, slippery mess maker.  On top of that, it took a 500 gallon tank with a continuous mixer and separate pump, a rather costly set- up. In an effort to find more efficient ways, we started working with granular flocculants.  Much easier to work with (no pre-mixing), much easier to store, and much easier to feed into the slurry.  Equipment size and cost were lowered dramatically. Our new Model AFD1 Automatic Flocculant Dispenser is like all our designs - simple to operate.  It contains a self-priming centrifugal pump that simply pulls the slurry in, and sends it back out to the pond to continuously stir and mix the pond and keep the solids suspended so that they can interact with the flocc particles.  There is also a poly tank that holds (2) 50# bags of flocc, and by using compressed air, the flocc is simply blown out onto the surface of the pond, where it is mixed in via the pump action.  Fill the tank with flocc, turn it on, and let it go - simple!

DOWNLOAD CENTER (click on any picture) BFK is an  Authorized Distributor of Cetco® Energy Services SlurrySep™ Flocculants and SlurryDry™ Slurry Solidification Agent (Super Absorbent), through their Master Distributor for Concrete Products, Slurry Solutions. The “base particle” of SlurrySep™ Flocculants is bentonite clay.  Bentonite Clay absorption/adsorption properties are very useful for wastewater purification.  (Absorption is when one substance enters completely into another; Adsorption is when one substance just hangs onto the outside of another.)    The many uses of Bentonite Clay range from coagulant to filter aid. It is a highly effective chemical, in granular form, for the purification of wastewater and sludge dewatering.  It is used as a sealing material in the construction of landfills to ensure the protection of groundwater from pollutants. Additionally, Bentonite clay is the active protective layer of geosynthetic clay liners.

SlurrySep TM Safety Data Sheet
Ever   tried   to   stockpile   waste   cement   dug   out   of   your   settling   ponds?      It   takes   awhile   to   dewater   and   dry,   and   when   it   rains,   the   material   turns   back into   “muck”.      With   the   use   of   SlurrySep™   Flocculants,   muck   issues   are   much   less   of   a   problem,   as   the   bentonite   clay   component   tends   to   repel additional water, keeping it from mucking up your stockpile. If there is still excess water, you can add SlurryDry™, mix it up with your loader, and absorb any remaining  water.  This is a great way to work with the BFK Bunker - let the material drain overnight.  Next morning, add SlurryDry™ to the pile, and load out the solids without excess water.

FLOCCULANTS & MODEL  AFD1  AUTO FLOCC DISPENSER

SlurrySepFlocculants: Help separate cement from slurry much more quickly than gravity alone, typically allowing for shorter and/or fewer settling ponds. In most cases, provide clearer water for use back at the reclaimer, minimizing the solids load on the pump and reclaimer plumbing. Bind many heavy metals present in cement slurry to the flocced cement particles, removing much of them from the slurry stream. Bind up and drop out many color pigments. Might make spent cement disposable at a land- fill. [Consult local landfill first] SlurrySep™ also helps to keep the reclaimer plumbing and pump internals clean, dramatically minimizing build-up. SlurryDry TM  SSG Super Absorbent: Forms a stable, non-flowing solid from concrete slurry that is easy to manage and dispose. Only adds 1-3% to waste volume for decreased hauling costs. Absorbs 200-300 times its weight in high pH wastewater.

Settling Pond Designs

Understand this: you can have the best reclaimer design, but with a bad pond system, you won’t be happy. Here at BFK we offer custom settling pond layouts specific to your plant, Free-of-Charge even before you make your purchasing decision. Give us your plant address and we’ll Map it on Google to determine your existing pond set-up. Or email us a basic layout of what you currently have, and we’ll take it from there.

Flocculants and Auto Flocc Feeders

We’ve been working with flocculants for more than 15 years, testing different types and learning how to make them work properly in your water system. We offer our own proprietary Automatic Flocculant Dispenser system that will dispense active flocc particles in your settling ponds. This helps to clean up your ponds, and settles fine particles like cement much more quickly than gravity alone. Check it out here, we think you’ll like it.

Slurry Dewatering Stand

Precasters, check this one out. This is the system you need to work in your plant where there is no need and no room for a settling pond. We realize you’re not ready-mix - you don’t usually need large, extensive settling ponds. The SDS is designed to collect the slurry from the reclaimer, capture the solids, and return clean water back to the reclaimer.  Works well with our Models M6 and R2 Reclaimers.

pH Control

The pH level of your water CAN be lowered. Using CO 2  to lower pH is a proven technique, and BFK is now pleased to offer the industry leader in pH Controls, the CO 2  Washout & Stormwater Treatment System from ATSI. ATSI has been in the pH game for over 20 years. It’s a perfect compliment to your Reclamation system.

Filter Press

We don’t build ‘em, we rarely even sell ‘em. But if you’re looking for one, we can hook you up with a press company that cuts no corners. We’ve heard all the sale pitches about automatic operation, no operator needed, pitch after pitch after pitch.   “Plug ‘em in and walk away”. Yeah right. Like BFK, they’ll lay it out for you, what to expect and what not to expect. No more, no less.
