Wastewater Vortex Products Vortex Dropper Formers Wastewater & Stormwater Speciality Products

Description

Vortex droppers lead wastewater into a drop pipe to a pump station or large manhole. The flow is turned and swirled as it enters the central drop pipe. Vortex droppers are used to avoid wastewater impinging on the side of the pipe or manhole in an uncontrolled manner.
Armatec manufactures vortex droppers to achieve smooth curved surfaces for the least turbulence. Reinforced concrete is poured behind the fibreglass former to achieve structural integrity necessary for the project. Stiffeners are integrated into the fibreglass to provide both strength during backfilling of concrete, and to physically lock the fibreglass to the concrete. Concrete pours are done in several lifts to avoid collapsing the fibreglass former.
Key Features
The benefits of Vortex Dropper Formers are it lowers many unwanted behaviours from the liquid waste:
• Less erosion
• Less turbulence
• Less entrained air that affects pump performance
• Less H2S and other gases evolved
• Fibreglass is surfaced with a special Armatec abrasion resistant layer to provide additional resistance to wear and erosion. The layer is incorporated during fibreglass manufacture, therefore is integral with the unit.
