Over 30 years
ago, when Nopon promotes its own products, pore
aeration device is mainly made of ceramic materials.
The ceramic product is good for producing small
air bubble, but it still has disadvantages of difficult
maintenance and is easy to brittle. Since then,
the high-density polyethylene (HDPE) material pore
aeration roasted by us has proven its remarkable
quality and durability in several hundreds of sewage
treatment plants ’ application process. Our patent
product: NOPON? cleaning system technology (formic
acid) can let the HDPE pore aeration device clean
with the best running status. HDPE aeration device
and the clean system together may help its work
life surpass 10 years. In German wastewater treatment
plants, Nopon’s HDPE pore aeration machine has been
working for more than 16 years. In order to satisfy
the high concentration sewage treatment craft and
the batch operation craft, in the 80's later periods,
Nopon researches and exploits EPDM rubber diaphragm
aeration device. In 1987, the first set of EPDM
rubber diaphragm aeration device is installed in
Finland. In 1991, the first set of EPDM rubber diaphragm
aeration machine is installed in Beijing East Chemical
and Industrial Factory. The rubber diaphragm aeration
device is suitable especially for the needs of intermittent
type aeration. For example: Biological nutrition
shift and SBR process, and it is also suitable for
the processes of industrial sewage aeration that
is hard to deal. There is massive eyelets in important
part elastic vibration EPDM rubber diaphragm, and
when air feeding, the tiny gas perforation can automatically
open and close when stopping air feeding, In this
way, it can prevent the sewage entering into the
aeration machine to make a block.
With the time moving on,
the core parts of Nopon pore aeration device system
maintain its unique style throughout. The products
are completely standard assembled. The aeration
machine made 20 years ago still may be replaced
and assembled by the products produced today. Without
modifying the entire piping system and the aeration
machine foundation, the ceramics, HDPE and the rubbers
diaphragm may displace each other at will.
Nopon
understands the fact well that there are great differences
in the product standard, the inspection procedure
and the idea worldwide. Therefore, products designed
and manufactured by Nopon are suitable for both
the plastic pipeline and stainless steel pipeline.
This mainly owes to Nopon aeration system’s unique
wedge-shaped joint piece. This joint piece has similarly
good effectiveness to the European standard 90 millimeters
pipe and the American standard 4 inches pipe. For
aeration system that exists and has already been
installed or the old style dome aeration machine,
Nopon has screw thread joint aeration device, which
can be installed in all size pipeline. The design
of Nopon aeration system has been taking customer’s
convenience as the first principle.
Based
on its core design, Nopon aeration system is considered
as the aeration technology’s perfect condition now.
The independent scientific research institution
test result indicates that, Nopon aeration system’s
oxygen transmission efficiency is completely consistent
to the figure promised. The aeration surface area
only does not decide the aeration efficiency, which
is in close relation with the air bubble size, the
diaphragm material, simultaneously with aeration
size, shape, and whole aeration system. The Nopon
disc diffuser system is unsurpassed when it comes
to oxygen transfer efficiency. One important reason
is that both the sintered disc and the rubber membrane
create bubbles of just the optimal size, not so
small that the boundary layer exchange speed is
too slow and not so large that the mass transfer
surface is too small .The overall shape of the diffuser
also aids in avoiding detrimental bubble coalescence.
The bubbles from a Nopon disc diffuser rise in columns.
The bubble stream retains its diameter, thus avoiding
bubble coalescence and high bubble velocities. As
a result the efficiency is much enhanced.
The
Nopon diffuser system is exactly a totally engineering
system .It is not merely a number of diffusers!
From the special joints between the diffuser elements,
to adjustable pipe pedestal and condensation water
discharge system, all that are produced by us have
showed our experiences in the field of diffuser.
The system that is required to work 24 hours a day,
365 days a year, with no more than occasional maintenance
stops must be manufactured by people with much experience.
Nopon can also provide the most effective and reliable
professional design according to the concrete situations
of every project at any moment.
The
design work starts at the moment of your inquiry.
Nopon has already developed and compiled a set of
simple operation computer software, which can fast
simulate the aeration system. Therefore, Nopon is
able to provide varied design proposals to for the
customer to choose according to the customer’s actual
situation and request. Fine and accurate CAD installation
diagram can help the user complete the equipment
installment without difficulty.
Nopon
Company guarantees that the oxygen transmission
efficiency, the system efficiency and the equipment
movement of the aeration device system meet the
design requirements. To guarantee excellent and
stable quality, all the developing, exploiting,
assembling and the quality controlling of Nopon
aeration system are completed by the headquarters.
Further more, the product quality produced by Nopon
Company has passed the IS09001 authentication.
