Rainwater

Problem:

Rainwater which is collected in a cistern can only be used in the household
for restricted applications (toilet flushing, washing machine). In most of the
cases, it is polluted by germs and, depending on the season, contains lots
of E-colibacteria and other coliforms and faecal strepto-cocci.



Solution:

WELLAN 2000 solves or considerably reduces this bacteria problem.

WELLAN 2000 is installed inside the suction pipe of the pump so
that a permanent head of water is maintained in the direction
towards the cistern. This exterminates moderate germ pollution
in the cistern, generally within but a few days.

In the case of heavier pollutions, germs and streptococci can
be reduced by up to 70%, pseudomones by more than 90%.

As yet, however, these figures lack the confidence factor.
