New on 500px : Salt Walvis Bay Namibia. by Africatracks by Africatracks

Namibia – Walvis Bay Salt.
.
The red colour indicates the salinity of the ponds.

Walvis Bay has one of the largest salt works in Africa. Refiners salt production process is based on the solar evaporation of sea water to produce 99,4% pure sodium chloride on dry mass basis.
Sea water off Walvis Bay, which is the only raw material, contains a 3,5% concentration of salts with 2,,9% sodium chloride. The water is pumped from a natural lagoon at a rate of 240m3 per minute into a series of pre-evaporation ponds and then through a series of concentration ponds.
