The Nipper is designed to provide cost-effective and efficient removal of gross pollutant matter from stormwater flow, and may be used for similar functions in trade-waste and other waste-water applications.
To help protect our precious waterways and marine life from untreated stormwater run-off from existing infrastructure such as stormwater systems that contain man made pollutants such as plastics, rubbish, litter, grit, sediment, oils etc, gross pollutant traps such as the Nipper CDS PL0506 Unit provides a solution to reduce these pollutants reaching our waterways.
Gross Pollutant Traps can be found in the market and come in many forms, shapes and sizes. These can range from large precast concrete systems to lightweight polymer systems. Generally the gross pollutant trap is selected depending on the size that is required to treat the stormwater runoff of the total surface area and the size of the pipe that is entering and exiting the system.
Introducing the Nipper CDS PL0506 Gross Pollutant Trap
The Nipper is ideally suited for the requirement of removing gross pollutants from stormwater infrastructure at the end of the line prior to connecting to local council stormwater mains or creeks and rivers. Manufactured from LLDPE, the Nipper Gross Pollutant Trap is light weight and provides easy accessibility to areas of installation. Using Continuous Deflective Separation Technology, the Nipper CDS PL0506 Gross Pollutant Trap has the lowest life costs of any gross pollutant traps due to its non blocking functionality. It is ideally positioned for use to treat stormwater runoff in small catchment areas such as the following applications
- Car parks
- Council Work Depots
- Bus and Train Stations
- Packaging Warehouses and Commercial Premises
- Industrial Sites
- Pre Screening Bio Systems
How It Works
The incoming untreated stormwater is directed into and around the circular weir in the upper module of the Nipper and then directed down inside the vortex chamber. Using CDS Indirect Screening Technology- the untreated stormwater passes through the indirect perforated stainless steel screen, into the outer chamber while maintaining the gross pollutants within the base of the unit. The treated stormwater is directed up through the outer chamber and passes through the outlet and continues downstream. Trapped gross pollutants are collected in the hemispherical bottom chamber of the Nipper.
How to Service The Nipper CDS PL0506 Gross Pollutant Trap
Opening the top cover of the Nipper allows direct access down into the bottom chamber so that the standard suction hose of a maintenance / pump-out cleaning vehicle can be lowered into the unit and collected gross pollutants can be simply and easily removed. As the flow of the incoming untreated stormwater is directed around and across the inner face of the stainless steel screen, the screen apertures are kept open by the force of the water stream and will not block with strained matter. This is the benefit of indirect screen technology. Therefore, there is very little need for the tedious extra work involved in cleaning the screens and filters with pressure water equipment so often found in alternative gross pollutant traps.
