AEL Mining Services

PROJECT TITLE:

AEL – 1000LPH Reverse Osmosis Plant

CUSTOMER DETAILS:

AEL Mining Services, a member of the JSE-listed AECI Group in South Africa, is a leading developer, producer and supplier of commercial explosives, initiating systems and blasting services for mining, quarrying and construction markets in Africa and Indonesia. AEL is also the largest supplier of explosives technology and initiating systems in Africa.

APPLICATION:

In February 2008 AEL’s R&D team pioneered and patented the world’s first commercial pyrotechnic spray drying plant, with the aim of the plant eventually providing all the delay powders that the company needs for its automated assembly plant. The spray drying process produces a uniform delay powder with enhanced flow properties from safe water based slurry feedstock. The process requires high purity, demineralized water for optimum process operation.

Previously AEL had been using a demineralisation plant to purify the needed process water, however due to the high operating costs of a demineralisation plant, AEL wanted to look into other options to treat the raw water. In attempt to cut costs for AEL, while still ensuring that the required water specifications were met, Water Icon designed a complete filtration, softener and reverse osmosis system to treat the pre-process water.
