Building valve solutions for water treatment
Inline Industries has a proud tradition as a vertical manufacturer, designing and
building a wide range of high-quality valves
I
nline Industries is
a pioneer in building
valve solutions for
OEM equipment and
water treatment plant
operations.
Inline Industries has
been providing innovative
valve solutions
to the treatment industry
for over 21 years. From manually
operated valves and automated
valve assemblies to high-performance
control valves, Inline has
built a strong reputation for manufacturing
high quality, consistent
and reliable products.
Inline has been able to
Inline Industries' 334 valve
with pneumatic actuator
achieve this by designing and
building its own valve products
as a vertically integrated manufacturer.
The company pours its own castings, machines, then
assembles and tests each valve to exacting industry standards.
Valves are cast to applicable ASTM material standards and designed
and tested to ASME B16.34 specifications to assure buyers
that the products will perform at the pressures and temperatures
for which they are designed. Each casting is heat stamped and
documented through an ISO 9001:2008 quality control process to
provide consistency and complete product traceability.
Inline offers a wide range of valve styles including valves with
compression ends for chemical injection tubing systems; two-way,
full and standard port valves with threaded, grooved or flanged
ends in economical low-pressure and high-pressure versions; and
three-way diverter and multi-port valves for bypass, tank farm
and filtration applications.
Inline also offers a spring return - normally closed - handle allowing
the lab to take samples at various points in the treatment
process, as well as valves capable of pressures to 4,000 PSI for
the most demanding applications. Inline can provide actuated
packages complete with accessories such as direct mount electric
or pneumatic actuators; limit switches; solenoids; and digital or
pneumatic positioners - all factory mounted and tested.
At the heart of Inline's success over the years has been its ability
to deliver. Inline's headquarters, located in Rosemead, Calif.,
houses an extensive multimillion dollar inventory, machine shop,
and automation center, enabling the company to ship 95% of all
orders complete in 48 hours.
Inline is supported by a select network of distributors that are
highly trained in helping provide customers with valve solutions.

Methanol metering for wastewater denitrification
An innovative metering pump from Fluid Metering boasts excellent performance when
dosing methanol into processes for removing nitrate from wastewater
N
itrate, an end-product of the bacterial
degradation of ammonia, is present
in high levels in untreated wastewater.
The release of effluent containing high
concentrations of nitrate into bays and
watersheds can have a devastating effect
on water ecosystems. Through a process
known as denitrification, water treatment
facilities therefore convert excess nitrate
into harmless nitrogen gas.
The anaerobic bacterial process that
breaks down nitrate is accelerated by
adding methanol to the wastewater. The
CeramPump QDX Hazardous Duty Metering
Pump from Fluid Metering has proven to
be an excellent choice for methanol metering
in wastewater denitrification, thanks
to its unique valveless design. This is especially
true in small to mid-size treatment
facilities, where methanol flowrates are
extremely low; this often causes valved
pump designs to become air-bound and
lose prime, the company says.
The CeramPump has only one moving
part in contact with the process fluid: a
During the pumping cycle the
CeramPump piston simultaneously rotates,
alternately opening and closing the
inlet and outlet ports of the pump, and
hence effectively functioning as a valve. At
no point are the inlet and out ports interconnected,
thus eliminating the need for
check valves. The pump drive is FMI's QDX
Hazardous Duty Drive, typically required
for pumping methanol.
Fluid Metering, Inc. patented the first

As with a conventional piston pump, the

the pumping function. However, this is
where the similarity to conventional piston
pumps ends.
rotating and reciprocating valveless pump
and has been providing fluid control solutions
for medical, analytical, chemical,
and industrial applications for over 50
years. In each of these markets FMI pumps
can be found from the laboratory to the
production floor, incorporated into OEM
equipment and instrumentation, as well as
process control and field installations.
Flowrates range from 2.5 µl/dispense to
4.6 l/min, with pressures to 200 psig. FMI
pumps will dispense and meter fluids for
millions of cycles with a drift-free accuracy
of better than ±1%.
