Vacuum sewerage is a mechanized system of wastewater
transport. Unlike gravity flow, it uses differential air
pressure to move the wastewater. It requires a central
source of power to run vacuum pumps which maintain
vacuum on the collection system . The
system requires a normally closed vacuum/gravity
interfacevalveat each entrypointtosealthelinessothat
vacuum is maintained. These valves, located in a pit,
open when a predetermined amount of wastewater
accumulates in the collecting sump. The resulting
differential pressure between atmosphere and vacuum
becomes the driving force that propels the wastewater
towards the vacuum station.

WATER FOR THE POWER INDUSTRY To cope with major changes in policy, climate and population, Degrémont Australia can help operators of thermal power plants (coal, lignite, fuel oil, gas, biomass, biogas and solar) meet key objectives http://www.degremont.com.au/industrial/industries-we-serve/power/
Similar to Danfoss APP pumps are designed for Reverse Osmosis (20)
It’s a fact that pumps on construction sites and in mines are often left
operating day and night. Usually they end up snoring most of the
time, causing unnecessary wear to pump parts and wasting electric
power. The result is increased service costs and high electric bills.
Control systems using external floats or level sensors are often
impractical in rough temporary surroundings.
Pumps work only when needed
FPC 100 automatic pump controller is the solution to overcome these problems.
Since they were developed over sixty years ago,
customers have come to trust the compact, heavy-duty
design of Flygt submersible pumps. The Flygt brand
was the first to provide a practical, heavy-duty electric
submersible pump that could withstand the severe
demands of construction site and mine dewatering
and yet still offer total portability

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Making fresh water possible
High-pressure pumps for seawater reverse osmosis applications
2. Fresh, clean water is vital to people
everywhere. But access to drinkable water from
municipal sources is often prohibitively
expensive or simply not an option.
The solution? It is all around us. Brackish water
and seawater are abundant, cheap and
renewable. But they need to be purified
to make drinkable water.
Danfoss Axial Piston Principle (APP)
high-pressure pumps are at the heart of more
and more small and medium-sized
seawater RO applications – because they
provide high-pressure reliably and
inexpensively.
Clean water via Reverse Osmosis
Reverse osmosis (ww) has emerged as a
preferred method for purifying brackish water
and seawater. The process is simple and
compact – and requires less energy than other
desalination techniques.
While RO is used in massive plants capable
of supplying major cities with fresh water, it
is also the ideal water purification technique
for a host of smaller applications in hotels and
resorts, aboard ships and on offshore
installations.
The heart of seawater RO systems:
Rugged APP high-pressure pumps
Danfoss high-pressure pumps set new
standards for small and medium-sized
seawater RO applications ranging up to
88 m3
/h (387 gpm).
Our dedicated high-pressure pumps build
on decades of experience in developing pumps
for other critical applications. Small in size
and unsurpassed in engineering quality, the
Danfoss range of high-pressure pumps are
at the heart of more than 15,000 seawater RO
systems throughout the world.
Cost-efficient Danfoss APP high-pressure
pumps function both as main pumps and as
reversing pumps (motors) for energy recovery
in seawater RO applications.
Dedicated seawater RO pump

Pump retrofit cuts energy and
maintenance costs at resort
The Challenge: Shangri-La’s Mactan Resort
and Spa, located on Cebu Island, is the
Philippines’premier five-star resort, requiring
1,000 m³ of fresh water per day for its 547
rooms, 7 restaurants and bars, massive pools
and spa. When the lush seaside retreat needed
to retrofit its old seawater plant,
management’s main objectives were to reduce
energy costs and minimize maintenance.
The Solution: The Danfoss APP 21 pump was
chosen as the plant workhorse, along with an
energy recovery device. Energy
consumption was reduced by an impressive
1.7 kWh/m3
, which corresponds to yearly
savings of € 62,050. Since the self-lubricating
APP 21 requires no preventive care,
maintenance was reduced to a minimum. As
an added bonus, noise pollution from the old
pump was so radically reduced that the plant
is now virtually inaudible from all floors – so
guests at Shangri-La’s Mactan Resort and Spa
can relax more than ever.
The Royal Navy converts aircraft
carrier from flash distillation to RO
The Challenge: HMS Ark Royal is the Royal
Navy’s largest Invincible-class light aircraft
carrier, with a crew of 685 and a Fleet Air Arm
of 366. The ship was originally fitted with flash
distillers to purify water, but their high energy
and maintenance costs led to a conversion
to seawater RO in 2005-2006. Salt Separation
Services Ltd., who built the new RO plants,
wanted to find the right high-pressure pumps
for the job.

6. An extensive range of high-pressure pumps and
accessories to power seawater RO applications
APP high-pressure pumps
Applications: APP pumps are designed to supply low viscosity and
corrosive fluids under high pressure, e.g. in seawater RO applications.
Design: APP pumps are based on the Axial Piston Principle, enabling
a very light and compact design. Lubrication of the moving parts in
the pumps is provided by the fluid itself, eliminating any need for
additional lubrication.
APP pumps are fixed displacement pumps with constant flow, since
flow is proportional to input shaft revolutions and pump displacement.
Materials: All pump parts are made of non-corrosive materials, e.g.
Duplex and Super Duplex stainless steel and carbon-reinforced PEEK.
