Green Rhino Ultra-fine Sediment & Oil Filters are primarily a fine filtration product designed for more sensitive environments (e.g. SSSIs, near rivers). They will filter out sediment as small as one micron in size. They can provide a cost-effective and quickly-deployed alternative to a sediment tank, particularly when using a Green Rhino Manifold System to harness multiple filters at once. Filters are available with a cam lock fitting for use with high pressure pumps. Each filter will capture 20kg of sediment before needing to be emptied and can be reused up to 20 times. Where standing water has a surface sheen, each filter will retain 2.5L oil and includes an integral hydrocarbon detector which turns dark blue when this capacity is reached. At this point the filter should be replaced. Where more oil is present, use Green Rhino Oil Retention Pillows to remove the slick before dewatering. Green Rhino dewatering filters are lightweight and include carrying handles for easy removal and emptying.
