Healthy office uses HEPA filters The American Lung Association of
Virginia's newly built 'Breathe
Easy' office building has
incorporated high performance
filter systems in an effort to
prevent its occupants suffering
from 'sick building syndrome'.
Two-stage electric heat pumps,
each with high efficiency particle
accumulation (HEPA) filters and
the ability to respond to bUilding
load changes, support seven zones
in the bUilding. The HEPA filters
are said to capture 99.97% of
airborne particles.
Sick building syndrome is a
recently recognised phenomenon
that occurs when a significant
number of building occupants
experience symptoms that do not
fit the pattern of any particular
illness and are difficult to trace to
any specific source. Sick building
problems may arise because of
improperly designed or maintained
heating, ventilation and air
conditioning (HVAC) systems;
office equipment, furniture and
supplies; and operations in the
building. "Air in normal office

Mannesmann Rexroth, which is
part of the global Mannesmann
Rexroth group, manufacturers
hydraulic motors for industrial
applications. It uses standard
hydraulic oils for equipment
testing. However, through con
tinuous use the oils become
contaminated with fine metal
particles and water. Therefore, the
company needed a system that

water and solid particles down to

additional benefit of reducing the
overall consumption of oil at the
facility and providing considerable
cost savings for the company.

buildings contains pollutants such
as pollen, animal particles, carbon
monoxide, formaldehyde, second
hand smoke, and volatile organic
compounds (VOCs) that can have
long-term effects such as liver and
kidney damage" says Donna
Reynolds, a spokeswoman for the
lung association. She adds: "These
pollutants can also cause
headaches, breathing difficulty,
sluggishness, nausea, burning eyes,
sneezing and coughing. "
According to Chuck Bowles, a
consultant with the Engineering
Consortium in Doswell which
worked on the building, the
tightening of buildings to reduce
heating and cooling costs has led to
poorer levels of indoor air quality.
The 1000 m 2 building cost
US$I.2 million, with $50 000 of
that spent on mechanical
equipment to improve air quality,

Steel mill clarifying contract
R-V Industries Inc of Honey Brook, flocculation, clarification and
Pennsylvania, USA, is to provi.de a settling, sludge collection and
95 11m wastewater treatment
system to process rinsewater from
an acid pickling line at one ofVoest·
Alpine Industries' steel mill in
Michigan, USA.
The order involves the
company supplying its slant tube
clarifier (STC) system to remove
suspended solids from the
watewatcr. In addition, it will be
providing engineering, manu·
facturing and start·up services for
the project.
The STC provides automatic
chemical addition and mixing,
storage, and filtration. Its design is
also said to allow for the future
addition of an integrated dual·
media filter.
R· V Industries provides a range
of wastewater filtration services
using microfiltration, reverse
osmosis and ion exchange.
