Flocculant for waste water settling Features and Benefits FLOC BLOCKS are solid blocks of slow release flocculant which work by releasing into the water stream trace amounts of anionic polymer chain molecules which act to bind together stone, soil, clay and chalk fines so that they will settle out rapidly leaving clear water for disposal or re-use. Very economical in use. Used in:
How to Use Prepare a secure dosing point, such as a mesh tray, under the water outfall. DO NOT IMMERSE. (See diagram below). Place block(s) under the water flow into lagoon etc and observe results. A curdling effect should be noted. Use one or more FLOC BLOCKS per water stream: the optimum number must be determined by trial and will depend on flow volume, solids content, and solids type. Normal use would be 1 block up to 3" outflow diameter; 1 to 2 blocks for 3" to 4" diameter; and 1 block per inch of diameter thereafter. For slower flow, fewer blocks are needed. Blocks will last several days depending on rate of flow. To avoid wastage place product so as to be wetted when flow is on but dry when flow is off. Note that sufficient “dwell time” - i.e. volume storage - must be provided to allow the flocculated solids to settle. In general, flocculated solids directed into a larger water body will settle to the bottom rather than re-disperse. For higher sloids content, a second dosing point firther downstream is often useful.
For more demanding separation requirements Morrison Mud Ltd offer a full range of on-site process options including special recipe Floc Blocks for difficult wastes; chemical treatment systems; screen and centrifuge processing systems for sale or hire. Safety Non toxic, safe in use. Contains anionic polyacrylamide . This material adheres to colloidal particles and if applied correctly is not carried over into the clarified water stream. | ||||
