WISY Vortex rainwater filters

Primary rainwater filtration is critical to keeping a rainwater tank clean and maintaining a good quality of water

Many people think rainwater harvesting is simply putting a pipe straight from the gutter into a tank. Initially it works well. By the second season the water colour is changing, and after long period of no rain the water has a funny smell to it.  In the third year everything starts to block that is connected to the tank. Water does not flow freely from the tank anymore and contains solid particles.

If the water tank is drained you will find a thick black layer of de-composing organic material at the bottom of the tank. Cleaning the tank is a dirty job and requires somebody to enter the tank and physically remove all the organic material.

The problem is that the tank has filled up with uncontrolled organic matter which affects the water quality. By not installing a proper pre-filtration system organic material will accumulate in the tank.

Pre- filters come in many shapes and sizes and need to be selected for every specific application.

If you want to ensure that the tank remains clean and that you would never have to clean the tank you must install a very fine primary rainwater filter – like complex Vortex inline filters. These filters strain out any items bigger that 0.28mm and they are guaranteed to keep your tanks clean and free of large debris.

If you just want a relative simple unit you can purchase a inline leaf filter. Depending on the volume flow of the water through the system the unite become bigger and can handle a large volume of water. The units are generally sized according to the roof surface that it can capture and filter water from
