Commercial: The Commercial rain harvester develops a complete system for a large operation. One filtering option is the larger Purain models. Contact us to find out more about these filters.
Professional: The Professional rain harvester often chooses:
- Purain-DN100 4” Self-Cleaning Rainwater Filter, an effective hydraulic jump filter that cleans itself automatically and ensures low maintenance and optimum water quality.
- Purain-DN150 6” Self-Cleaning Rainwater Filter, like the DN100 but can handle higher flows
Standard: Standard users often rely on the Leaf Eater Advanced Downspout Filter, which moves leaves and debris away from the flow of water. This unit can be used as a debris removing device even when rainwater is not being collected.
Hobbyist: The Hobbyist relies on a basket filter, that is easily accessible through a removable manhole cover on the rainwater tank. Rain flows in through a top port, runs through the basket and out through a bottom port. To keep rain in the tank clean and healthy, the Hobbyist must empty the basket filter after every rain.
Commercial: The Commercial rain harvester develops a complete system for a large operation. The Orival ORS Self Cleaning Submersible Pump Suction Filters works continuously to ensure debris-free water and to protect pumps and other equipment.
Professional: Professionals often use Premium Floating Intake Filters to pull the cleanest water from the best part of the tank – just below the surface. This extends the life of the pump while providing highest quality water from the tank any time that water is needed. Two options are:
Standard: The Standard rainwater harvester will want a pre-pump filter that fits in the tank – just below the surface – extending the life of the pump while providing the highest quality water from the tank any time that water is needed. Two options are:
Commercial: When it comes to Commercial pre-filtering components, post-pump filtration skids are custom fabricated to meet the needs of the individual project.
