Wastewater treatment is ‘sew’ easy
Proof’s flameproof stand
Local wastewater treatment firm SewTreat has launched
the SewTreat Build-Own-Operate (B-O-O) model,
which makes the installation and operation of an on-site
wastewater treatment solution more affordable for
businesses of any size.
Under the B-O-O model, SewTreat handles the complete
manufacturing, construction, and installation of a treatment
plant at no cost, after which repayments are made for the
plant over a 10-year period at a predetermined rate for every
1 000ℓ used.
The process is designed and operated to comply with
pre-set qualities and SewTreat is measured against them. If
the water quality is not as per design, then the client simply
won’t pay for the water. SewTreat provides professional
technical operators such as chemical engineers to operate
the plants, guaranteeing the final water quality.
Maintenance and ensuring optimal efficiency of
the installed plant is done by the SewTreat team on a
continuous basis. All maintenance, consumables, operators,
and quality management are managed by their qualified
on-site technicians.
In addition, the company takes steps to mitigate plant
failure. An app-based system alerts the chemical engineers
on site of any failures or trips, prior to availability being
an issue. In addition, the systems are designed in parallel
to allow technicians to single out faulty equipment, bypass
faulty equipment, or replace equipment while the system
stays operational.
The safety spindle from
Proof Engineering.
Proof Engineering revealed a newly designed tamper-proof
spindle for Ex sockets alongside its latest range of Orion
and Crater branded Ex glands.
Part of the Hudaco group of companies, Proof
Engineering manufactures flameproof, explosion-proof,
and non-flameproof plugs, sockets, adaptors, and cable
couplers. Its extensive product offering focuses on the
mining and tunnelling industries.
Donovan Marks, director at Proof Engineering, says that
the innovative tamper-proof spindle, developed by Proof
Engineering in close collaboration with an end user, is a
must-see. Thanks to its innovative design, the plug can only
be removed once the circuit has been isolated, contributing
to the safety of underground mine personnel.
Shedding light on increased production
The presence of several Pilot
Crushtec International Generac
Tower Lights at a coal mine
in Mpumalanga has made it
possible for the mine to add an
extra shift and as a result, increase
output substantially.
Pilot Crushtec provided
the Tower Light systems to
equipment hiring specialist
Lambson’s Hire at very short
notice.
Lambson’s received an
urgent request from the mine
for seven sets of high-power
lighting systems and Pilot
Crushtec provided the products
immediately. The Generac VT8
is equipped with four 1 000W
metal halide floodlights and each individual unit is capable
of illuminating an area of about 4 200m².
