Evaporation cannon handles mine wastewater
After identifying the need for an environ-
mentally-safe evaporation system to reduce
excess wastewater at mines, I-CAT Water
Solutions developed the I-VAP 500 evapo-
ration cannon, which is capable of handling
500 m
3
per 12-hour day. The evaporation
rate is 60 % to 65 %, depending on ambi-
ent weather conditions, I-CAT Technical
Manager Morne Van Wyk explains.
This latest wastewater treatment and
management system from I-CAT Water
Solutions ensures that wastewater from
mine sites does not enter the general envi-
ronment and thereby contaminate water
further downstream. A particular bene-
fit of the I-VAP 500 is its low energy-use
to evaporation ratio, Van Wyk notes.
The I-VAP 500 can cover 32 000 m
2
,
with an automatic oscillation option of
up to 359 deg. An integrated turntable
bearing allows the operator to over-
ride the oscillator manually in order
to reposition the fan barrel quickly. In
addition, the cannon has an adjustable
angle of throw, with a height adjust-
ment of 7 to 45 deg.
It produces a large spray pattern that
allows for a longer float time, thereby
increasing the evaporation rate. The can-
non works by atomising the water through
38 nozzles, which are available in PVC,
stainless steel, brass or nylon, depending
on the application.
The unit discharges 21,3 litres a minute
through each nozzle, with the 55 kW pump
delivering a maximum pressure of 10 bar.
The droplet size is 150 µ to 180 µ, with a
throw distance of 80 m to 110 m.
The I-VAP 500 features an integrated
fan and nozzle ring design, together with a
high-pressure hose and a 40 mm cam-and-
groove quick disconnect female coupling. It
boasts a premium efficiency 0,10 kW oscil-
lator motor, and is supplied with a 50 mm
electrical cord of up to 30 m, with other
options being available.

Continued economic pressure always
produces a conundrum when it comes to
purchasing decisions, especially with an
increased focus on reducing costs. Andrew
Mentis, however, raises the concern that
there may be a very real danger that infe-
rior quality products will be used, and this
will have a detrimental effect on safety.
Elaine van Rooyen, Marketing Manager
at Andrew Mentis, explains that this is
especially true for its flagship product.
“It is critical that when purchasing
flooring grating that a quality product
with structural integrity is procured as this
material is most often used as access walk-
ways and platforms and therefore needs to
be able to hold the required personnel and
equipment without any cause for concern
over their safety,” she says.
Mentis floor grating is engineered to
take specific loading which ensures opti-
mum safety of the people walking on or
working in those areas. Van Rooyen raises
the issue that while cheaper products may
well look identical, and to the untrained
eye will not have any apparent physical
difference, they may not be capable of car-
rying the requisite load.
“Often it is only after the floor grating
has been installed and in use for some time
that the danger of its reduced load-bearing
capacity will become apparent. And this is
No room for compromise on quality
why we believe there is an urgent need to
educate the market about this problem,”
van Rooyen says.
One of the major differentiators that
Andrew Mentis flooring products have is
that they are subjected to an extensive
quality manufacturing process. “We do
not compromise on quality, which means
that under no circumstances are we pre-
pared to cut corners. Apart from the strict
controls under which our products are
manufactured, we do not use commercial
quality mild steel.We have standardised on
SAE 1008 which ensures consistency and
also prevents damage to our machines.”
Andrew Mentis was established more
than 65 years ago and has numerous ref-
erence bases in a number of industries
in South Africa. Operating from large
premises in Elandsfontein, the company
manufactures floor grating, expanded
metal and hand-railing systems in mild
steel and stainless steel, and guard-railing.
