National Rainfall and Potential Evaporation


With Climate Change it

is highly probable that

this distribution will

intensify; the east will

get wetter and west

drier.

Note skewed distribution of rainfall, and decrease

westwards while evaporation rates increase westwards

Water

• The world is becoming desperately short of

freshwater, threatening our very survival.

• In South Africa, the country's water supply is

at risk.

• The nation's energy needs expected to

grow.

• Can this be turned around before it's too

late?

• Do you see energy and water imbalance

linking security (of energy and water)

towards a sustainable future.

Energy and Water

• Energy and water are intricately connected.

All sources of energy (including electricity)

require water in their production processes:.

• Energy is itself required to make water

resources available for human use and

consumption (including irrigation) through

pumping, transportation, treatment, and

desalination.

Water & Waste Treatment

Supplies products

and solutions for

wastewater treatment.

Municipal Wastewater Treatment Plant, has used Alfa

Laval drum thickeners and spiral heat exchangers for more

than 10 years. In 2013 they needed to increase capacity

and invested in Alfa Laval

AS-H Belt Thickener – a fairly new product in Alfa Laval’s

comprehensive portfolio within waste water treatment.

Modernisation of the Wastewater

Treatment Plant

The new fully automatic Alfa Laval

ALDEC G3-75 decanter at the Vejen

Wastewater Treatment Facility dewaters

biological wastewater sludge up to a dry

solids content of 24%, a clear

improvement over the belt press.

A new machine was specified to dewater

35 m3/hour with 353 kg dry solids/hour

and produce sludge with a dry solids level

of 24%, using 8 kg of polymer per 1 tonne

of dry solids and with a filtrate quality

level below 1,000 mg/l.
