A safe, effective and easy to use product.
Hadex is especially intended for disinfecting drinking water tanks and piping systems, and for preserving drinking water in tanks.
Hadex is a liquid product, which disperses rapidly through the water to be treated.
The water treated with Hadex remains suitable for consumption, which prevents water being wasted and saves time.
Hadex is permitted in the Netherlands by the Ministry of Health, Welfare and Sport under permit number 9574N.
The Shipping Inspectorate has fully accepted Hadex.
Normal dosage:
1 litre to 50 m³ drinking water (1 : 50,000) (=20 ml Hadex in 1 m³ water.)
This low dosage must be added regularly and it reduces and prevents germ growth and algae and slime formation. (Dosage complies with N.S.I. drinking water regulations)
Effective after 30 minutes.
Extra dosage:
1 litre to 25 m³ drinking water (1 : 25,000) (=40 ml. Hadex in 1 m³ water).
This dosage is used if the drinking water is suspected of being poor quality and/or it contains suspended particles that can strongly promote the growth of bacteria.
Effective after 30 minutes.
High dosage (shock treatment):
1 litre to 5 m³ (1 : 5000) (200 ml Hadex in 1 m³ water).
The high dosage is used to treat drinking water under epidemic conditions, i.e. if the water is or is suspected of being infected with bacteria.
Effective after 30 minutes.
The high dosage (shock treatment) must always be used for the first treatment in order to disinfect the drinking water, the tanks and the piping after new construction or repairs. Contact time approx. 6 hours.
NOTE:
Read the Hadex data sheet for additional information and/or consult your supplier for the desired information. Check the condition of the tank(s) and the quality of the drinking water at least once a year.
