 3P Technik specialise in providing high quality rainwater/ stormwater filtration and cleaning devices for domestic and commercial applications.
Filter The first cleaning step in the rainwater system is the filter. The rainwater flows from the roof to the filter. Here dirt particles and debris are separated from the water. The cleaned water flows to the tank. The dirt is washed to the stormwater pipe or soakaway with a small amount of rainwater. All 3P rainwater filters have stainless steel inserts, which are easy to remove and easy to clean. Their many different working principles and connection possibilities allow for their use in many different installation situations. By using an underground tank, the water is stored in dark and cool conditions. Here the second cleaning step takes place. In the water column, any fine residual particles settle to the bottom of the tank. The rainwater Calmed Inlet prevents any disturbance of this sedimentation layer. At the same time the Calmed Inlet ensures that oxygenated water is introduced to the lower layers of the stored water in the tank. This oxygen rich water prevents anaerobic reducing conditions forming in the storage tank and ensures that the water stays fresh. Any particles that are lighter than water (e.g. flower pollen) float slowly to the water surface. The expertly designed 3P Overflow Siphon, with a skimmer effect, removes this floating layer. The regular overflow from the storage tank is important to get the optimum water quality. It prevents souring of the water. The floating layer could otherwise build up over time, and so reduce oxygen diffusion at the water surface, which in turn could lead to anaerobic reducing conditions in the tank.
Floating Pump Intake The 3P Pump Intake floats at all times, suspended just below the water surface where the cleanest water lies. From this position the water is abstracted by the pump. A ball float, filled with air, suspends the intake, which has a further filter and a check valve.
