SLURRY
TO CLEAN
WATER

 

Mudhens can be used for most slurry water applications.  Originally designed for the demanding world of concrete options include pH adjustment, larger pumps, slab carts, and trailer mounts.  The equipment can be configured and utilized in many ways:

  • It pulls slurry water out of your containers, from a pool or any vessel

  • It cleans the water and discharges it to drain or back into a container for reuse in your equipment.

Whatever your needs wheel it into an elevator or through a doorway to your work area.  Mudhens can be used just to clean a dumpster, pit or water tank and re-circulate the water until the vessel is clean (i.e. "slurry to clean.")

 

 

Handling Concrete Slurry --- Has Never Been Easier, Job Site Ready
The MudHen is a portable, reliable, flexible and easy to use solution for concrete slurry.  Jobsites that create slurry and need to store and transport slurry can save thousands of dollars by utilizing a Mudhen.  

The Mudhens are designed with multiple modes of operation.  Equipped with a 10 foot hose to suck slurry water out of any container.  A standard garden hose connection on the output allows you to send the water to drain, to reuse the water, or to use the clean water to wash down your equipment.  Cakes can be easily disposed of using optional trays or sludge bags as well as a standard wheel barrel or can.

Benefits

sEnvironmental & Regulatory Concerns

ELIMINATE REGULATORY CONCERNS

With increased EPA enforcement of industrial suspended solids many contractors have been hit recently with large fines. Most contractors are unwilling to carry the huge financial risk and liability associated with not cleaning their water.  Some contractors have left the efficiency of wet grinding and face new operational difficulties with dry grinding.

The MudHen eliminates your financial liability over regulatory concerns potentially saving you thousands of dollars, allowing for water reuse and recycling on site.

 

Easy to use controls.

 

EASY TO USE

MudHens are portable and supported by large casters to easily move the unit around a jobsite.  The machines can be pushed onto the job site by hand, they dont require a forklift.  Simple mechanical controls and heavy duty construction are used to eliminate employee errors and problems.  Concrete water recycling was never so easy!.

 

Mudhen Double Wall Diaphragm Pump.

 

RELIABLE --- MADE IN THE USA

The concrete water system is built right here in the USA.  All components are parts are interchangeable with standard components that are easily found.  No more waiting for service and parts that originate from outside North America.  The MudHen concrete water system is built to last, and when service is needed components are carefully selected to minimize the downtime.  The MudHen has the lowest cost of ownership for maintaining.

 

Mudhen - in use.

 

FAST & PRODUCTIVE

The MudHen M1 concrete water system comes standard at over 200 gallons per hour of processing capacity and can be easily accessorized with a larger compressor to handle over 500 gallons per hour of capacity.  The machines can outpace most teams of concrete professionals that saw and grind with industrial equipment which benefits your staff and customers.

 

 

Applications

MudHens can solve a variety of slurry water issues for different applications.  They are commonly used on stone, ceramic and glass slurry as well as other slurries that have a high quantity of suspended solids.

Slurry waters can be effectively treated to be EPA (Environmental Protection Agency) compliant.  Pump trucks, stone and tile saws, cement and mortar mixers along with industrial slurries can be treated to remove the vast majority of suspended solids.  The pH can easily be treated to meet EPA requirements. 

The recycled water can be reused on site to reduce water consumption.  The sludge is collected and compacted for easy disposal. 

For years concrete wash out slurry has been a challenge.  With a MudHen concrete washout system compliance has never been easier.  All MudHen products are made in the USA.

 

Application:  Concrete Washout   We have portable solutions to treat concrete washout on site including as well as the following harmful sediments:  Concrete, Terrazzo, Paint, Stucco, Mortars, Grout, Sone, Tile, Glass.

 

Sizing - What size filter press do I need?

Concrete Redi Mix Truck - Washout.If youre working in an industry where wastewater is a byproduct, youll need an effective method to treat the slurry water.  A filter press is the perfect solution, but it isnt just one size fits all.  

Its important to consider size before investing in a filter press.  Its easy to simply choose the biggest option and assume the filtration process will go smoothly as long as it isnt overloaded.  But bigger is not always better so you should choose a filter press after carefully considering your needs and the application you are using it for.

In certain applications, cake and water quality can drop if the press is oversized.  Additionally, a filter press than is too large can make your costs rise, not only with the initial purchase but when running the machine.  Thoughtful design and pairing with other technologies can reduce the size and overall cost of your purchase.

 

BUYING DECISION - Which Mudhen to Purchase?

Factors to Consider:

  1. How many gallons of slurry do you need to process per day?

  2. The quantity of solids that are in the slurry?  --- Slurry with less solids require less filter chambers.

  3. PATIENCE or SPEED?  For slurry with more solids, although all the Mudhens will do the job, the more collection chambers there are the less time you'll spend separating and emptying them.  For example, to process 500 gallons of concrete slurry per hour you'll want to go with a larger filter press (MH1 or MH2), otherwise you'll be spending too much time manning the machine  (i.e. emptying plates).

    • SELECTING THE RIGHT UNIT --- HOW FAST DO YOU WANT TO FILTER WATER?
      Using a 55 gallon drum of slurry as our benchmark, 50% solids:

      • Mini - slurry processing capacity:  120 gallons per hour

        • With 3 filter chambers - you'll have 6 cleaning cycles per drum

        • (A cleaning cycle is the number of times you'll have to stop slurry separation to empty and clean the filter chambers)

        • Recommendation:  If you accumulate < 200 gallons of slurry per day, the Mudhen Mini is good for you

      • MH1 - slurry processing capacity:  360 gallons per hour

        • With 7 filter chambers, you'll have 1 (or less) cleaning cycle per drum

        • Recommendation:  For processing slurry everyday.

          • If you accumulate between 200 and 400 gallons of slurry per day, the Mudhen MH1 is good for you

          • If not fast enough, go with the MH2

      • MH2 - slurry processing capacity:  720 gallons per hour

        • With 13 filter chambers, you'll have 1 cleaning cycle (or less) per two (2) drums

        • Recommendation:  For large warehouse floors, stone fabricators and multiple crews

          • If you accumulate between 400 and 800 gallon of slurry per day, the Mudhen MH2 is good for you

          • If not fast enough, go with the MH4

      • MH4 - slurry processing capacity:  1250 gallons per hour

        • With 23 filter chambers, you'll have 1 cleaning cycle (or less) per three (3) drums

        • Recommendation:  When slurry accumulation exceeds 800 gallons of slurry per day.

         

  4. Mudhen Size & Weight - although all 4-Mudhen models are portable, the Mini and MH1 are smaller and weigh less so they may be better suited for maneuvering within job constraints.

 

COMPRESSOR SIZE - Air Requirements

  • Dry filtered air is required to minimize the maintenance on the system

  • Dewalt Compressor, model D55168.MudHens can be adjusted to effectively operate in a wide range of locations and conditions

  • MudHens are equipped with an air operated diaphragm pump - this pump requires a minimum of 5 scfm of air to operate with a tank size between 15 and 30 gallons (an air compressor with a 15-gallon tank is the smallest size tank that can operate a MudHen)

  • RECOMMENDED COMPRESSOR - Mudhens run best using a 15 / 30-gallon air compressor set between 50 and 80 PSI - see Dewalt D55168 Compressor (right.)   Once properly adjusted to your filtration requirements and processing times, the Mudhen may be left to operate unattended.  For crystal clear water output, efficiency of operation and fast processing times set the compressor at 50 PSI and adjust it upwards to a maximum of 80 PSI.

Operation

Mudhen Controls - schematic.

  1. Connect air compressor hose to Mudhen air fitting

  2. Place slurry line and screener (included) into the container of slurry

  3. Attach output hose and secure the hose into the container that the clarified water will flow in

  4. Adjust regulator on Mudhen control panel to 30 PSI

  5. Turn operation controller "on" the Mudhen will begin to pump slurry through the unit

  6. As back pressure builds in the Mudhen and the pump slows, adjust PSI regulator upwards in 20 pound increments.  This is done up to 80 psi, do not and never exceed 80 PSI.

  7. Eventually the Mudhen's pump will stall or you'll hear it trying to gulp for slurry, this is the indication that the collection chambers are full of solids or the slurry container is empty (the pump will not be harmed as it gulps for more slurry to process.)

Leaking Plates

Mudhen - leaking plates.

 

Pre-Coating the Filter Cloths.  If the plates leak while pressure builds apply more pressure via the hand jack.  Each filter plate or chamber includes (2) filter media cloths with a filter efficiency rating of 5 microns.

The filter cloths require solids in your slurry to ensure the efficient operation of a Mudhen (i.e. the chambers will leak if drinking water is pumped through them.)

Pre-coating the filter cloths increases their efficiency rating to 1 to .6 microns

Pre-coating the filter cloths should be your 1st step to ensure the purity of the liquid being discharged.

PRE-COAT STEP
"GO SLOW & LONG ENOUGH"

This step is only for the first filling of the plates.  After the initial release of your first cakes you'll still start the Mudhen slowly (10 PSI), but only for a few minutes as the filter cloths are already coated.

As you observe the clarity of the water being discharged, the PSI may be gradually increased to the optimal operating setting between 50 and 80 PSI. 

 

2-Pre-Coat Methods:

  1. Loading Method - Using your own sediment.  Start the Mudhen at the slowest speed possible (1 - 10 PSI).  Depending on the particle size and volume of sediment in your slurry, pre-coating times will vary (2 to 40 minutes).

  2. Mix Method - Mix 20 lbs. of diatomaceous earth (or perlite or dicalite) with 10 gallons of water.  Pump this milkshake mixture through the filter chambers to instantly pre-coat the filter cloths.  You may immediately being normal operation of the Mudhen using its optimal operating speed of 80 PSI.

Once the filter cloths are properly coating (as determined by the purity of the water being discharged), you can increase the PSI into the press.

If the water being discharged ever begins to look cloudy simply reduce the PSI to the pump.  This will slow down the intake of slurry going into the filter chambers while it continues to pre-coat the filter cloths.  Additionally, if speed isn't too important you can leave the machine operating slowly (i.e. 50 PSI).

 

Caked Solids
Emptying the filter chambers and dropping the caked plates.

The powerful 3/4" diaphragm pump (completely adjustable, 0 - 30 GPM or 0 - 100 psi of air) will push and compact the solids in the filter chambers.

The filter chambers, held in place within the heavy framework of the Mudhen, are pressed together with 5000 lbs. of force from the hydraulic hand pump.

As the filter chambers fill, pressure gradually increases and the purity of the liquid being discharged also improves as the solids fill within the filter chambers.

Once full (the liquid being discharged will cease to flow), operator intervention is required to release the dry the caked plates and empty the chambers.

As each filter chamber is separated, the caked plates are released and dropped into the collection tray or a wheel barrel.

Drying / Cleaning Procedure:
  1. Remove slurry line from sludge and allow pump to pump air for a minimum of 5 minutes (the longer it operates the drier the cake)
  2. Turn operation controller to off, adjust air to 30 psi
  3. Turn operation controller to dry
  4. Turn isolation valve A located right below controls to its off position (ref Operation drawing, above)
  5. This will allow more air to travel through the plates
  6. Water will sputter out of the output hose
  7. After 2 minutes open the isolation valve A
  8. Turn the operation controller to off
  9. Loosen the hydraulic jack pressure relief valve
  10. Separate the chambers and clean the screens with the enclosed scraper
  11. After every 1 to 4 weeks depending on the nature of the slurry pressure wash the plates & cloths to ensure open and clean pores for proper filtering
  12. DO NOT LEAVE SOLIDS IN THE MUDHEN FOR MORE THAN 1 TO 2 DAYS DOING SO CAN RUIN THE SCREEN CLOTHS INSIDE THE SYSTEM.

 

END of DAY CLEANING
At the end of each day of use it is important to flush out any slurry from the system.  This includes flushing the air pump and the filtration plates as well as any hoses.  This can be done by directing the clean water discharge hose from the system and running its clean water right through the Mudhen.
