Every aspect of RaHa Clean Close Water is done so that water is clean. Inlets pipes go to bottom of the tanks. At end of the inlet pipes, there are provisions for calming inlet.
The Calming Inlet performs several functions that are imperative to maintaining a high quality of water within your rainwater harvesting tank.
The calming inlet acts as a mosquito barrier by creating a water trap between the inlet pipe and the tank, preventing mosquito entry into the tank.
Additionally, the calming inlet helps to introduce oxygen into the cistern water – helping to prevent stagnation – prevent anaerobic decomposition.
Perhaps most importantly, the calming inlet prevents any sediment bed from being disturbed. The calming inlet broadcasts the water up into the tank rather than allowing it to splash down. By keeping the sediment bed intact you help to improve the life of your pump – if any – since it will not be sucking up sediment, provided that a floating extractor is used.
Made of food quality polyethylene, the high quality construction of the calming inlets reduce water costs and the strain on water consumption.
CALMING IS JUST ONE OF 4 STEPS OF CLEANING WATER
FIRST CLEANING STEP
The first cleaning step is the mechanical filter which retains or rinses certain coarser particles in the water due to its mesh width.
The pre-purified water enters the rainwater storage.
SECOND CLEANING STEP
Small particles flow through the filter, heavier ones accumulate on the ground, lighter (eg flower dust) rise and float on the surface.
In order that the incoming water does not disturb the sediment, it has to be introduced as slowly as possible from the ground upwards.
This is done by the so-called calm intake .
THIRD CLEANING STEP
The above floating particles leave the cistern at the overflow by means of the wanted skimming effect. This skimming effect “sucks” these particles off the water surface.
At the same time, the siphon forms an odor seal as well as a rodent barrier with a channel connection.
FOURTH CLEANING STEP
The cleanest water is in the cistern 15 cm above the sediment layer and 10 cm below the surface of the water and can be taken from there with a floating extraction.
This is done either with a submersible pump in the cistern or with a suction and pressure pump in the house.
