POL-E-Z™ Liquid Flocculants for Coal Processing

May 22, 2014

One of the key elements needed to successfully run a coal preparation plant is properly managing water supplies and 
maximizing water recycle and limiting carbonaceous solids disposal. Most operations use thickeners followed by either twin 
belt press filters or pond/dewatering cells. Flocculants and coagulants are typically required to remove solids and produce 
required settling rates to permit clean recycle water that is needed for the continuous cleaning of fine coal. These products 
are also used to optimize the underflow density in the thickener and percent cake solids on dewatering filters. Flocculants 
are key to any water management regimen and are available in liquid or powder form. While powders can appear to be less 
expensive, their use can often involve significant additional and largely hidden costs and hazards. Liquids can help the 
environmentally responsible operator avoid these issues.
