Filtration & Purification Systems

Overview

Filtering and purification systems play a critical role in rainwater harvesting, especially when the collected water is intended for reuse. The level of treatment depends on the intended application. Filtration has three stages, with each step progressively improving water quality making it suitable for potable (drinkable) use.

• Sediment Filtration Units: Once water is collected, this is the first step of filtration. It removes particulates to protect downstream equipment and is a required step before UV filtration can occur.
  
• Carbon Filters: Carbon filters are an optional level of filtration used in combination with sediment filters to improve the clarity, odor, and taste of rainwater. For a reliable and efficient filtration system, it is recommended to place the carbon filter after the sediment filter and before the UV disinfection stage
  
• Ultraviolet Light (UV): UV light is required for potable use, as it provides fast and effective disinfection by destroying bacteria, viruses and other pathogens. These systems are easy to install and can be customized for different applications, making them a reliable choice for rainwater purification.

Features and Benefits

• Essential for indoor use: Whole-house filtration systems are critical for safely using collected rainwater indoors.
• Removes diverse contaminants: Filters out dust, organic matter, and atmospheric pollutants picked up during collection.
• Tailored treatment levels: Different filtration stages cater to water quality requirements based on intended use (e.g., irrigation vs. potable use).
• Protects health and safety: Ensures harvested rainwater meets health standards, especially for human contact or consumption.
