recorded by the PLC, and process
information is collected and fed to
the operator, who then has complete
control of the process. Using that
information, the PLC can automatically
compensate for changes in the
process due to changes in viscosity,
pressure, temperature,

and so on. This allows the process to
keep the flow relatively constant and
pulse free. DMK SmartPump technology
is able to monitor and measure
pumping characteristics without having
any sensors immersed in the liquid
being pumped. Therefore, the DMK
SmartPump technology allows for
a vast array of liquids to be pumped
without having to worry about sensor
wear and tear. DMK SmartPump systems
can pump nearly any size particle,
with current models allowing for
sizes up to 25 mm and future models
exceeding 50 mm. In addition, the
DMK SmartPump has been proven to
pump high-viscosity fluids without the
need for a bulk unloader and minimal
head. The DMK SmartPump has been
tested to pump fluids at pressures of
up to 40 bars. - Design Management

A new, low-volume
biowaste-treatment system
The MicroEDS BioWaste Treatment
System (photo) was recently introduced
for biologically hazardous waste
decontamination, typically required in
the biopharmaceutical sector, laboratories
and research institutes. The lowvolume
system is certified to ASME
and ISO/EN standards for treating
BSL 1, 2 and 3 waste using a batch
process. MicroEDS includes a number
of major technical advances, including
thermal energy regeneration, low energy
usage, 100% positive release for
treated waste and electronic-records
generation. The MicroEDS has been
developed to fit into new lines or to
be retrofitted into existing facilities.
The system is designed to operate
at a thermal treatment parameter of
121°C for 15 min, as well as variable
temperature, time and F0 lethality settings,
for specific requirements. With
capacities varied to suit a wide range
of waste volume from 150 to 500 L/d,
the MicroEDS is supplied with controls
Personal protection against
H2S exposure
The new ARA H2S single-gas detector
(photo) is designed to protect users
from toxic levels of exposure to hydrogen
sulfide. Classed as an item of personal
protective equipment (PPE), the
ARA H2S is completely maintenancefree
and offers continuous monitoring
of exposure to H2S levels. It offers a
choice of display for users, either a
lifetime countdown or concentration
lifetime exposure, and it is possible to
switch between the two, if desired. The
ARA H2S can also provide short term
exposure limits (STEL) or eight-hour,
time-weighted average (TWA) readouts
for greater visibility into the overall
health of a worker. Once activated, the
ARA H2S detector will continuously
operate until the end of a two-year
period, giving users appropriate warnings
to source a replacement. There is
also the option for a three-year lifespan
model, which offers a hibernation
mode, ideal for users who only visit
the site on occasion. - ION Science

This hybrid feeder saves space
and investment costs
The Crossover feeder (photo) is a
hybrid feeding solution suitable for a
wide range of greenfield and brownfield
applications. Thanks to its innovative
modular belt-over-apron design,
the Crossover feeder is said to
deliver unmatched levels of availability
and reliability for bulk material transportation
at lower overall costs. The
Crossover feeder design features a
reduced height of up to 50% as compared
to conventional feeding technology.
This lower height requirement
provides an opportunity for capital
investment savings by decreasing the
excavation and civil works required.
For retrofit applications, the reduced
height profile allows the Crossover
feeder economically replace existing

containment is constantly maintained
and there is always a positive
release prior to discharge of treated
waste. - Suncombe Ltd., Enfield,
