The filter combines a layered nylon monofilament sediment barrier rated to 150µm with an oil-absorbing inner layer that captures up to 2.5 litres of light hydrocarbon contamination as the discharge water passes through. A single filter replaces the need for two separate products in low-risk contamination scenarios. The integrated hydrocarbon detection indicator monitors oil loading continuously: when it turns dark blue, the filter has reached oil absorption capacity and must be replaced, not emptied.
A standard sediment filter stops suspended particles but allows hydrocarbons to pass straight through to the drain. An oil retention pillow soaks up surface sheen but does nothing for suspended sediment. On sites where both hazards are present at low levels, managing them separately requires additional equipment, additional monitoring, and additional handling. The oil and sediment filter addresses both in one unit: the outer 150µm nylon monofilament layer removes suspended sediment from the water column, and the oil-absorbing inner layer captures residual hydrocarbon contamination as the water exits. The result is discharge water cleaned of both sediment and light oil contamination in a single pass through a product that attaches to the discharge hose in the same way as a standard sediment filter.
Combined sediment and oil filtration: Layered nylon monofilament construction filters suspended sediment to 150µm while the oil-absorbing inner layer captures up to 2.5 litres of light hydrocarbon contamination in a single pass.
Integrated hydrocarbon detection indicator: Printed directly onto the filter. When it turns dark blue, the oil absorption capacity is full and the filter must be replaced. This is different from the sediment-only filter indicator: here, dark blue means replace, not just stop.
Reusable up to 20 times: For sediment-only applications, the filter can be emptied, rinsed, and redeployed. Once the hydrocarbon indicator activates, the filter must be replaced and disposed of as hazardous waste.
300 L/min flow rate: Designed for use with a 2-inch pump discharge hose. Note the flow rate is lower than the standard 150µm sediment filter (450 L/min) due to the additional oil-absorbing layer.
Lifting straps: Integral lifting straps for safe and easy handling when the filter is full of sediment.
Reusable cable ties included: For securing the filter collar to the discharge hose. Designed to break under excess pressure before the filter bursts.
Highly visible orange colour: Reduces trip risk when deployed at the discharge point.

Site managers and environmental managers on construction, utilities, and civils sites where excavation water is known or suspected to carry light hydrocarbon contamination alongside suspended sediment. Typical scenarios include dewatering excavations adjacent to oil-filled cable infrastructure, sites near fuel storage areas or plant maintenance zones, and locations where ground conditions suggest residual hydrocarbon presence. This filter is not the correct specification for heavily contaminated water: where significant oil sheen is present, Green Rhino Oil Retention Pillows should be used to remove the surface sheen first, with this filter capturing any residual contamination.
Dewatering excavations alongside live oil-filled cable routes in utilities and infrastructure work where residual oil contamination of groundwater is a known low-level risk.
Filtering discharge water from excavations on sites with a history of light hydrocarbon ground contamination where a sediment-only filter would not provide sufficient protection.
Providing combined sediment and oil filtration on highway maintenance excavations where surface water runoff may carry light fuel residues.
Replacing a sediment-only filter mid-session when the hydrocarbon indicator on the sediment filter turns dark blue, signalling oil has entered the water.
Providing a single-filter solution on sites where both sediment and low-level hydrocarbon contamination are anticipated from the outset.
Step 1: Before fitting, assess the level of contamination in the water. If significant oil sheen is visible on the surface, deploy Green Rhino Oil Retention Pillows to absorb the sheen first. This filter handles residual light contamination after the bulk sheen has been removed.
Step 2: Slide the open end of the filter over the 2-inch discharge hose end. Ensure a secure overlap at the collar.
Step 3: Secure with the two reusable cable ties provided. Tighten to approximately two thirds of the hose width. Do not use rope, chain, or any other rigid fastening.
Step 4: Position the filter at the discharge point. The orange colour is highly visible to reduce the risk of trips.
Step 5: Start the pump. Monitor the integrated hydrocarbon indicator throughout pumping. When the indicator turns dark blue, stop pumping immediately. The oil absorption capacity is full. Replace the filter before resuming.
Step 6: When the filter is full of sediment but the hydrocarbon indicator has not activated, pause pumping, empty the sediment, rinse with clean water, and redeploy. The filter can be reused up to 20 times in sediment-only applications.
Step 7: When disposing of a used filter that has captured hydrocarbons, treat as hazardous waste. A filter used for sediment only with no indicator activation can be disposed of in general waste.
Using this filter for heavily contaminated water without treating the source first: this filter is designed for low-risk light contamination. Where significant oil sheen is present, remove the bulk contamination with Oil Retention Pillows before fitting this filter for residual treatment.
Continuing to pump after the indicator turns dark blue: unlike the sediment-only filter where dark blue means stop and investigate, on this filter dark blue means the oil capacity is exhausted. Continue pumping and contaminated water passes straight through to the drain. Stop immediately and replace.
Disposing of a used filter in general waste after hydrocarbon capture: any filter that has absorbed hydrocarbons must be disposed of as hazardous waste under the Environmental Protection Act 1990 and the Hazardous Waste Regulations 2005.
Using this filter on a 3-inch pump outlet: the filter is designed for a 2-inch hose only. For the MAX 750W pump with a 3-inch outlet, the filter cannot be secured correctly.
This filter removes sediment and absorbs light hydrocarbon contamination. It is not rated for heavily contaminated water or significant oil spills. Monitor the integrated indicator throughout pumping. Stop immediately when it turns dark blue. Dispose of used filters that have captured hydrocarbons as hazardous waste. Discharge through this filter is not a guaranteed compliance permit: confirm with the Environment Agency that the water quality at your site is appropriate for surface water discharge before pumping.
Empty sediment after each use where the indicator has not activated. Rinse with clean water and dry before storage. Inspect the filter media and indicator before each redeployment. Replace immediately when the indicator turns dark blue. Store away from direct sunlight and solvents.
Q: When should I use this filter instead of a standard sediment filter?
A: Use this filter when there is a known or suspected low risk of light hydrocarbon contamination in the excavation water alongside suspended sediment. Typical scenarios include dewatering near oil-filled cables, sites with a history of light ground contamination, or when a sediment filter's hydrocarbon indicator has turned dark blue mid-session and oil has entered the water. For clean water with sediment only, the standard reusable sediment filter is the correct and more cost-effective choice.
Q: What does it mean when the hydrocarbon indicator turns dark blue on this filter?
A: On this filter, dark blue means the oil absorption capacity is full and the filter must be replaced immediately. This is different from the sediment-only filter, where dark blue means stop pumping because oil is present but the filter cannot remove it. On the oil and sediment filter, the oil is being captured, and dark blue is the signal that the 2.5L capacity has been reached. Continue pumping after that point and hydrocarbon-contaminated water will pass straight through to the drain.
Q: Can I reuse this filter after it has absorbed hydrocarbons?
A: No. Once the hydrocarbon indicator has turned dark blue, the filter has reached its oil absorption capacity and must be replaced. It cannot be emptied of hydrocarbons and reused for oil capture. For sediment-only applications where the indicator has not activated, the filter can be emptied, rinsed, and reused up to 20 times.
Q: How should I dispose of this filter after it has captured hydrocarbons?
A: Any filter that has absorbed hydrocarbons must be disposed of as hazardous waste under the Environmental Protection Act 1990 and the Hazardous Waste Regulations 2005. Do not place it in general site waste. A filter used for sediment only, where the indicator has not activated, can be disposed of in general waste.
Q: What is the flow rate and which pumps is it compatible with?
A: This filter has a maximum flow rate of 300 L/min and is designed for use with a 2-inch pump discharge hose. This is lower than the standard sediment filter at 450 L/min due to the additional oil-absorbing layer. It is compatible with the MAX PL080001 (500W) and PL080003 (530W) submersible pumps. It is not compatible with the MAX PL080002 (750W) 3-inch outlet pump.
Q: What should I do if there is significant oil sheen on the water surface before pumping?
A: Do not rely on this filter alone for heavily contaminated water. First deploy Green Rhino Oil Retention Pillows to absorb the bulk of the surface sheen at source. Once the visible sheen has been removed, fit this filter to capture any residual light contamination in the water column during pumping. Using this filter without removing significant surface sheen first will exhaust the 2.5L oil capacity rapidly and may not achieve compliant discharge.
