When selecting a compressor, the continuous start/stop operation

compressor. The electric compressor, below, includes a dual
control switch. When using the compressor with a Mudhen, set
it to continuous operation. Our recommended gas compressor,

virtually no reference to the instructions, although an easy to use owners manual and DVD

to be tied down because it will buck and spray water at times
if not secured.)

slurry through the unit.
back pressure builds in the Mudhen and the pump slows, adjust
the psi on the regulator in 20 pound increments. This is
done up to 80 psi,
but not to exceed 80 psi.
filter screens in the plates will capture the solids and the clean water exits
the system through the output hose. The operator can leave the unit
while it is processing slurry.
the Mudhen pump stalls or pumps infrequently (or when the
clear water being discharged is minimal or stops), the Mudhen
is full of solids - its filter plates are full. At this
time you'll also hear the air pump
trying to stall (from back pressure).
This is your signal that the filter plates are full and that
the caked plates need to be dropped . . .

If a Mudhen 1.0 is $17,500 with shipping, that's about $500 per
month that needs to be justified ~
See Fun Story . . .
Story at the World of Concrete Show, 2014:
employee for a concrete company stops by our booth at the show
boss is complaining about spending $300 per day per crew per
job site on slurry removal cost
he hears the monthly costs to own is under $500 he instantly
calls his boss to walk over to the booth
get together and talk . . . then they say,
"Wow, we work 5 days a week and we average $300 per day
per crew in slurry costs".
"That's 20 working days per month @ $300 per day or $6000
"The machine is $17,500 with shipping, divided by $6000
means we'll pay for one machine in 3 months."
"I'll take one now and if it all works out I'll order one
for each crew next month (they have 6 crews) and one for a
spare for the unexpected . . ."

you want to process per hour?

that same 55 gallon drum is only a quarter full of solids,
slurry processing time increases by 50%
~ 3 cleanings / drum
more filter plates you have in a Mudhen (or the less solids in
the slurry), the longer your slurry processing times will be
before you have to stop processing to empty and clean the filter plates
(which takes less than 5 - 10 minutes).
Rule: If you are accumulating < 200 Gallons of Slurry
a Day, the Mini Mudhen is right for you.

Screen Efficiency Rating: Filter screens are rated
at 1 - 2 microns nominal. If you absolutely must have 1 micron
efficiency, a $120 Filter is available and it is attached to the
discharge outlet (with the filter installed, discharge will be 4 - 5 gallons
a minute). The replacement filter media for this filter is
$15.00 and it is typically replaced every one to
Filter Screens: Intermediate
cloth, $58.00; End cloth, $32.00. Typical replacement is
every two years on concrete grinding, drilling and cutting
applications. But they can last
only one month if the concrete is allowed to harden on the screens
(typically after a week). Once the concrete has harden in the
pores of the screens, slurry water will not be able to pass through
. . .
of Needing New Filter Screens: As you are pumping
slurry through the machine - up to 80 psi or so - the air pump will
stall (which is normal,
this also tells you that the filter chambers are full). But
when you open or separate the filter chambers and you see that there
is very little caking (debris) inside the chambers - mostly just
slurry water. This means that the pores in the screens are
closed and either need cleaned or replaced. As previously
mentioned, they should be expected to be replaced about every
Screen Maintenance: We tell everyone to thoroughly
clean the units at the end of the day including the screens and
inside the chambers with a pressure washer - and especially if the
unit is going to sit for a week or so. However, guys have been
know to let the units sit for a month with slurry in them and they
work just fine.
Choose a Mudhen?
MudHen concrete water system is portable and utilizes large
casters to easily move the unit around a job site. The
concrete water equipment can be pushed into the jobsite by hand
and doesn’t require a forklift. The press utilizes
simple mechanical controls and heavy duty construction to eliminate
employee errors and problems. Concrete water recycling
was never so easy!
- MADE IN THE USA
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 Model 1.0 Concrete De-Watering 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. Model 1.0 will easily outpace
most teams of concrete professionals that are sawing and grinding with
industrial equipment, while the Mini Model keeps up to a (1) 30"
grinder on its initial cuts (which produce higher concentrations
