Klipfontein WTW upgrade and refurbishment –
mechanical and electrical
Bosch Munitech has upgraded the Klipfontein Water
Treatment Works (WTW) in Vryheid, KwaZulu-Natal, from
a 10Ml/day facility to a 54Ml/day facility. The project team
consisting of Rory Audie, Musa Mzolo and Clive Louis, started
in January 2014 and the project is nearing completion with
only commissioning of the works outstanding.
The scope of works included the installation of two new
vertical turbine raw water pumps and pipework, and the
complete civil refurbishment of the raw water pump station.
A new MCC panel was designed and installed in the raw water
pump station. Large scale dredging was undertaken around
the intake points to remove 30 000m3 of sludge that had built
up around the tower.
The design and installation of two new circular clariflocculators with four paddle mixing units was completed. The
refurbishment of the two existing clarifiers by fitting mixers into
an extended centre stilling well, was done to allow for more
slow-mixing to take place and aid in flocculation.
Nine new monolithic floor-type rapid gravity sand filters with
new filter panel control desks and automated backwashing
function were installed. New backwash pumps, blowers
and compressors were installed to allow for the increase in
backwashing capacity.
A new MCC was designed and installed to allow for new
instrumentation and control of the new filters and clariflocculators, along with telemetry and SCADA system to allow
for automated control of the raw water, high lift and numerous
reservoir pump stations.
The Chlorine dosing room was upgraded to allow for
automated dosing of 1-tonne cylinders and to meet safety
requirements.
