Flocculation

Flocculation is the use of a flocculating agent to cause fine particles to join together into a floc. At Grassmaster we use the process of flocculation to treat water on a site so that the water is correctly filtered to allow movement of water into waterways without polluting it.

Usually, after heavy rain, the sediment basins on sites become muddy with the sediment rising to the top of the basin. Grassmaster is called to treat the water by mixing water and calcium chloride (flocculating agent) and spraying the mixture into the basin allowing the particles to floc and the sediment to drop to the bottom of the basin. This leaves the water clear, allowing it to be discharged into the waterways or used on site. The flocculating agent requires 24 – 48 hours to activate and the sediment to settle. 

Grassmaster uses calcium chloride as its flocculating agent as it is the most cost effective and environmentally friendly due to the solubility of the product.
