Bacteria Will Ensure Rainwater Purity
Few people think about the cleanliness of rainwater. Clear drops falling from the sky seem crystal clean.
But the truth is shocking: rainwater is often dirtier than roadside ditch water.
Why? You’ll understand if you follow each drop’s journey — from cloud to your rainwater tank.
What Rainwater Really Contains
At first glance, rain seems like plain water. But raindrops absorb everything in the atmosphere:
-
exhaust fumes,
-
dust and soot,
-
heavy metals and sulfur compounds,
-
bacteria and fungal spores.
When it flows from rooftops, it picks up:
-
leaves and dust,
-
bird droppings,
-
moss fragments and dirt,
-
insects and microplastics.
The result is cloudy, smelly, microbiologically unsafe liquid that quickly pollutes tanks, pipes, and plumbing systems without proper treatment.
Why Traditional Filtration Isn’t Enough
Mechanical filters in rainwater collection systems fail to remove key contaminants. They:
-
don’t eliminate dissolved organics,
-
can’t remove bacteria or odors,
-
clog quickly and require frequent maintenance.
Chemical treatment is expensive, complex, and environmentally unfriendly — and it can’t guarantee consistent water quality.
Biological Filtration — the Natural Way
The most logical and eco-friendly way to purify rainwater is biological. Beneficial bacteria:
-
break down organic pollutants,
-
improve the microbial quality of water,
-
eliminate odors,
-
work reliably and without chemicals.
It’s a safe, sustainable solution that requires minimal human intervention.
Kolomaki Rain — a Smart Biofilter for Your Tank
Kolomaki Rain is a compact and efficient biofilter, designed specifically for rainwater purification. It comes in two models:
-
external — installed next to a buried tank,
-
integrated — fits directly into the tank’s opening.
Inside, everything is ready to go — including a pump that provides water circulation, aeration, and ventilation, creating ideal conditions for bacterial activity.
How the System Works
-
Pre-filtration — removes large debris.
-
Biofiltration — organic matter is broken down by aerobic bacteria.
-
Aeration and circulation — support healthy microbial life and prevent stagnation.
The process is natural, automatic, and effective.
What You Get
With Kolomaki Rain, you fully solve the problem of dirty rainwater:
-
Your tank water becomes clear, clean, and odor-free.
-
Tank surfaces self-clean thanks to water movement.
-
Pipes and irrigation stay clean and free of buildup.
-
Even fixtures connected to rainwater remain clean and hygienic.
Kolomaki Rain — the filter that makes rainwater truly useful
No chemicals, no odor, no dirt — just freshness and purity.
