Product information " Greywater recycling plant GWI 1.2-750 (capacity 750 l/day)"
This system can treat up to 750 liters of graywater per day.
The GWI 1.2 – 750 graywater recycling system is the compact indoor solution in the GWI series for treating graywater from showers, bathtubs, and sinks. It is particularly suitable for single-family homes with low to medium water usage, small residential units, and commercial applications with low to medium greywater generation.
Through a combination of biological treatment and modern ultrafiltration (membrane filters), graywater is reliably purified and made available for industrial use. It is specifically used where drinking water quality is not required—e.g., for toilet flushing, cleaning purposes, or garden irrigation. When operated properly, the treated water meets the quality standards of the EU Bathing Water Directive for service water applications.
The system enables efficient savings of drinking water and supports sustainable water management in small to medium-sized residential and commercial units.
The delivery time for the system is approximately 4–6 weeks.
Functionality & Technology
The overall purification process consists of biological treatment followed by ultrafiltration. The treated water is then stored in the service or clear water tank.
The BioMembrane filter technology used ensures reliable separation of the biomass from the graywater through its barrier effect and guarantees a high hygienic quality of the service water.
The system consists of several coordinated components:
- Filtration tank with membrane filter for treating the graywater
- Service water tank for storing the treated process water
- Control cabinet with integrated control system and aeration pump
Greywater treatment is fully automated via an integrated control system. If there is insufficient service water available, standard-compliant drinking water is added to ensure a reliable supply at all times. After power outages, the system automatically resumes operation.
Applications
The GWI 1.2 – 750 graywater treatment system is designed for:
- Single-family homes
- Smaller apartment buildings or residential units
- Office and commercial units with low to medium water usage
- Guesthouses, vacation rentals, or outbuildings
It is ideal for any location where low to medium volumes of graywater need to be treated efficiently and in a space-saving manner.
