STEAM ELECTRICAL ENERGY SOLID WASTE WATER PRIORITISED IMPLEMENTATION OF OZONATED WATER FILTRATION PLANT WITH UV (MEMCON)

A LOOK AT THE REQUIREMENTS Clean water prior to distribution to municipal storm water drain Water for applications throughout the factory For uses other than in end products Suitable for end product for future purposes

A LOOK AT THE SCIENCE 1 Factory effluent enters effluent plant and solids are removed. 2 Water is filtrated in effluent plant. 3 Blender mixes 25% municipal and 75% reworked filtered water. 4 Ozonated filtration removes bacteria. 5 Only 75% goes into filtration plant where it is ozonated into a silo. 6 Goes through UV system back into the factory.

IMPLEMENTED WATER FILTRATION SYSTEM – COST-BENEFIT CAPEX R 2M Projected 75% reduction in municipal water supply Projected annual direct saving R 1.35M Investment break-even 18 months
