rainwater treatment

AlienScrOGstarted grow question a year ago

good evening guys, I'm here to ask you something very important... I'm very worried about the research carried out in recent years which talks about pollutants in rainwater what I'm asking you is how do you filter everything and make the water good or even drinkable

Activated Carbon Filter: Removes odors, organic compounds, and some chemicals. Reverse Osmosis System: Provides thorough purification by removing dissolved salts and minerals. Boiling rainwater is an effective method to make it safe for drinking. Boiling kills or inactivates most harmful microorganisms, including bacteria, viruses, and parasites, making the water safe to consume And a lot more ways 🍻

I would not use rain water. Too much polution, plus ph goes so high , you need heavily adjust it. Tap water, dechlorinator and you way more in safer zone than with rain ... World is changing, what worked even 20 years ago now especially in urbanized areas will bring more harm.
