one energy source, but how to optimise decentralised systems with
various fuel sources to achieve energy efficiency, reliability and criti-
cal process protection.
A typical scheme could comprise renewable power generation
sources such as wind and solar. However, these pose challenges to
system reliability and performance, given their inherent intermittent
contribution and associated disturbances. Gas-to-power programmes
in Southern Africa are yet to overcome challenges such as natural-gas
pipeline infrastructure and moderating market prices.
Diesel-engine power plants have synchronous technology and
contribute a high level of operational stability for standby or prime
power applications, together with mature diesel-fuel supply chains.
Manufacturers of diesel gensets are making steady technological
gains that reduce capital intensity and emission levels, and enhance
power output and efficiency. Diesel-generated power is still likely to
feature on its own or incorporated into hybrid solutions for many
more years.

ROUND UP
CDE South Africa keeps it clean
CDE Global is the largest wet processing equipment manufacturer
in the world and works with its customers to maximise their return
on investment and gain significant competitive advantage while
minimising environmental impact. The company has established
an office (CDE SouthAfrica) in SouthAfrica and appointed Nicolan
Govender as Regional Manager for Southern Africa. The African
continent has high infrastructural demands and the materials
washing solutions CDE develops are ideal for quarrying and
mining sectors supplying the construction market. By using CDE
equipment, the environmental benefits are significant, not the
least of which is that up to 90% of the water is recycled when a
wet processing washing plant is combined with a CDE AquaCycle
water recovery system. A typical sand washing operation uses a
minimum of a hundred thousand litres per hour, which is basically
clean water being converted into waste water and then pumped or
piped away into a settling dam, at which point it exits the washing
system.With a CDEAquaCycle, 90% of this waste water is recycled
for immediate reuse by the customer.This does not only minimise
water consumption, but also aids businesses to show compliance
when reapplying for water licences.
