The manufacturer informs: 

A domestic system for the production of practically pure and totally mineral-free water (conductivity and TDS are therefore zero) that is ideal for use in an aquarium, be it fresh or marine.

The system consists of four successive stages:

• 5 mcr sediment cartridge: removes suspended particles and rust or particulate residue from the water; recommended replacement every 6 months or 3000 litres of produced water; the transparency of the container gives the user the possibility to constantly monitor the cartridge's state of wear and tear

• pressed activated carbon cartridge: removes chlorine, heavy metals, drug or pesticide residues and other substances potentially harmful to the aquarium from the water; also recommended to be replaced every 6 months or 3000 litres of produced water 
   
• Vontron membrane: specially developed for use in domestic systems, ULP1812 series membranes are designed for the treatment of low salinity water such as that flowing in our waterworks.
  

Already working at relatively low pressures, ULP1812s are perfectly suited for use in domestic systems and, in particular, for the production of osmotic water for aquariums.

• activated carbon post-filter: cartridge made from premium quality activated coconut carbon to remove chlorine and chloramines, heavy metals, harmful contaminants and pesticides from the water, making the water clean, clear and free of harmful substances.

Flush Valve for membrane flushing:

the system is equipped with a valve that allows a regularand membrane maintenance withfeeling to extend its average life.

Simply turning the valve knob causes the waste water to re-enter the vessel and flow out from where the permeate would normally flow out, thus subjecting the membrane to the washing process that improves its operating conditions.

Included in the package are:

- spanners for the vessel (membrane container) and cups

- steel diverter for connection to the water mains with 1/2" female thread (tap connection)

- 5mt of white 3/4" hose

- instruction manual in Italian
