Surface Water


Surface water refers to the filtration of natural fresh water sources found above ground such as river or dam water. Surface water is typically rich in natural organic matter, colour, turbidity and bacteria. The designed water treatment plant needs to properly address all of these constituents. 

How it works

Treating surface water depends on the demand of water. Large systems typically use coagulation and flocculation to remove the bulk content, followed by clarification of the water using carbon, and finally adds disinfectant such as chlorine. 

Smaller systems operate best when used with Ultrafiltration. If the water still has colour an inline coagulation step can be added. The advantage of using Ultrafiltration for small or large systems are:

  •  Consistent water quality regardless of feedwater changes

  • Removal of bacteria and viruses 

  • Low maintenance

  • Can be automated

  • Very compact in size

  • Professional advice 

  • In-depth water analysis  

  • Engineered to fit

  • Compact design

  • Automated and smart 

  • Flocculation testing

  • Mineral balancing


The cost ranges significantly depending on the size and complexity of the system. You should budget from R40 000 for a residential system.
