DYNO-MAX
2000� �Pro� Software creates a full vehicle dashboard on your PC. Features include: real-time trace graph display, adjustable limit warnings,
pushbutton controls, user configurable analog and digital gauge ranges, color
graphing, test report database, instant playback, inertia compensation,
�Smart Record�� trigger points, adjustable data dampening, full data import/export, semi-automatic zeroing, voice alarms, wireless Pocket DYNO-MAX� interface,
drag strip Christmas tree console, etc. (Click for full list of features.)

DYNOmite Data-Acquisition Computer displays
and records true unlimited Hp, torque, RPM,
elapsed time, etc. at up to 1,000 readings per second (per channel). It will
even automatically apply SAE correction factors for air temperature, barometric
pressure, and relative humidity.

More than acceleration Hp can be measured with DYNOmite absorption units,
because they utilize an actual strain gauge equipped torque transducer.
Measuring power under a controlled RPM load is vital for proper mapping of
engine management systems and guess-free emissions work. Avoid �dynos� that
simply spin the vehicle�s tires up against their roll�s inertia (�flywheel
resistance�) without having any ability to simultaneously control and measure
absorption load. Rather than measuring the torque, they derive it from the
acceleration (similar to extracting horsepower from drag-strip data). Such units
can not maintain a MPH or RPM setting, while also displaying true torque and Hp
� like a DYNOmite can!

Sustained Hp and top end require an absorption dynamometer (i.e. a DYNOmite system).
Unlike �acceleration spurt� inertial testing, these can load a vehicle
indefinitely.* The absorber allows running controlled RPM step or sweep Hp
tests. Everything is under computer control via the included Electronic Auto
Load.

Simulate driving conditions on your chassis dyno by letting DYNO-MAX and your PC take
control. DYNO-MAX features a �Road Load Simulation� mode that simulates vehicle
momentum, air drag, rolling friction, etc. Enter the vehicle�s weight and drag
data and then allow the software to monitor MPH vs. applied Hp, as it adjusts
the dyno�s road load accordingly. To the car�s driveline and operator, the feel
is like actually driving.

Front, Rear, or All Wheel Drive cars and trucks can be tested on the appropriate
model automotive chassis dyno. Many allow front/rear torque bias monitoring and
bidirectional mounting. Even large bikes and ATVs fit the 700 Hp dual-roller
assembly. We can also convert many other manufacturer�s
older, single axle, chassis dynamometers to AWD, with full Electronic Axle
Synchronization, at a fraction of the cost of a new installation!

Dynamically balanced and machine traction-grooved rollers dramatically limit vibration and tire slip! Test most production
vehicles (up to 150 MPH and 700
Hp) on our smallest automotive dual-roller assembly. Larger diameter roll systems easily handle sustained higher speed testing at
race car power levels. (**Capacities
are approximate, as they are primarily tire safety and traction limited � higher torque requires tie downs.)

Fix driveline problems that might never show up in the
garage, like shifting issues, driveshaft vibration,
brake squeal, bearing noises, brake shudder, exhaust rattles, etc. - without
costly field testing.

Verify emissions under load using your existing, or our optional (digitally integrated)
DYNOmite 5-gas, exhaust analyzer. Proper emission testing procedures require
repeatable absorber load control, impossible on simple inertia dynos. No more
trying to use unloaded idle data to verify that repaired vehicles are in
emissions compliance. Send customers for state inspections with confidence.

Low profile, ramp loading allows installing the 12" dual-roller units above ground - or
in the driveway. Casters let you roll it to a corner when not in use (just raise
the anti-vibration leveling pads). No dedicated test bay, or digging up floors,
required.

Rapid on-off set-up makes it practical to skip those old time-consuming road trips.
Just drive it on, strap it down, hook up the tach (or
use �Smart Ratio��) and test � a full report
prints out automatically!

While membrane-based separations of liquids from solids have enjoyed increasing popularity over the last 20 years, the technology has an inherent Achilles heel that affects all membrane devices: fouling. This long-term loss in throughput capacity is due primarily to the formation of a boundary layer that builds up naturally on the membranes surface during the filtration process. In addition to cutting down on the flux performance of the membrane, this boundary or gel layer acts as a secondary membrane reducing the native design selectivity of the membrane in use. This inability to handle the buildup of solids has also limited the use of membranes to low-solids feed streams.

(Figure1)

To help minimize this boundary layer buildup, membrane designers have used a method known as tangential-flow or cross-flow filtration that relies on high velocity fluid flow pumped across the membranes surface as a means of reducing the boundary layer effect. (See Figure 1)

In cross-flow designs, it is not economic to create high shear forces, thus limiting the use of cross-flow to low-viscosity (watery) fluids. In addition, increased cross-flow velocities result in a significant pressure drop from the inlet (high pressure) to the outlet (lower pressure) end of the device, which leads to premature fouling of the membrane that creeps up the device until permeate rates drop to unacceptably low levels.

(Figure 2)

Instead of producing high cross flow, an alternative method for producing intense shear waves on the face of a membrane is developed. The technique is called Vibratory Shear Enhanced Processing (VSEP). In a VSEP System, the feed slurry remains nearly stationary, moving in a leisurely, meandering flow between parallel membrane leaf elements. Shear cleaning action is created by vigorously vibrating the leaf elements in a direction tangent to the faces of the membranes.

The shear waves produced by the membrane's vibration cause solids and foulants to be lifted off the membrane surface and remixed with the bulk material flowing through the membrane stack. This high shear processing exposes the membrane pores for maximum throughput that is typically between 3 and 10 times the throughput of conventional cross-flow systems. (See Figure 2, above)

The oscillation produces a shear at the membrane surface of about 150,000 inverse seconds (equivalent to over 200 G's of force), which is approximately 10 times the shear rate of the best conventional cross-flow systems. More importantly, the shear in a VSEP System is focused at the membrane surface where it is cost effective and most useful in preventing fouling, while the bulk fluid between the membrane disks moves very little.

Because VSEP does not depend on feed flow induced shearing forces, the feed slurry can become extremely viscous and still be successfully dewatered. The concentrate is essentially extruded between the vibrating disc elements and exits the machine once it reaches the desired concentration level. Thus, VSEP Systems can be run in a single pass through the system, eliminating the need for costly working tanks, ancillary equipment and associated valving.

The disc pack hold up volume of a system with 1,400 ft2 (130 sq. meters) of membrane area, is less than 50 gallons (189 liters). As a result, product recovery in batch processes can be extremely high.

 
Emulsified oil are serving as lubricant as well as coolant in various metal industries such as steel making and metal cutting. Disposal of emulsified fluid is a very tough environmental pollution issue. It has high COD and oil/water fully emulsified. Conventional bio-chemical treatment consumes large amount of chemicals and high running cost yet still requires multiple post-treatment steps. The disposal of solid cake will ultimately contaminate underground water. Conventional membrane treatment faces low flux and severe fouling issues. VSEP can simplify treatment process. It has high anti-fouling ability and high recovery ratio. Concentrate can be put as fuel and permeate can achieve discharge standard.

At startup, the VSEP system is fed with a slurry and the concentrate valve is closed. Permeate is produced and suspended solids in the feed are collected inside the VSEP filter pack. After a programmed time interval, valve on concentrate line is opened to release the accumulated concentrated solids. The valve is then closed to allow the concentration of additional feed material. This cycle repeats indefinitely.
