Greywater re­cy­cling - a new water source

Up to 65% of our water needs comprise showering, bathing, washing hands and washing machine usage.  The resulting waste water from these activities is the so-called greywater.

This greywater can be very economically and easily recycled, for example treating it for reuse in toilet flushing and irrigation.

Profitable Advantages

Double savings
By reusing greywater, you save not only the mains water but also the wastewater costs. This makes amortization of projects possible in less than 5 years.

Sustainable investment
With greywater recycling, you can achieve a better assessment with „Certifications for Sustainable Building“.  This can increase the value of your property and can mean tax advantages as well. Market your building as „Green“.

Smaller space needs
A greywater system needs very little space for the tanks since the water is collected daily and directly reused for the building needs.


The principle with AQUALOOP

System Construction - Greywater Recycling

1. PURAIN pre-filter 5. Sludge pump
2. AQUALOOP growth bodies 6. RAINMASTER Favorit-SC
3. AQUALOOP blower 7. UV-unit
4. AQUALOOP membran station 8. Tanks

Functionality
The greywater from showers, bathtubs and hand washing is pre-filtered through the highly efficient PURAIN filter before entering the bioreactor. The integrated PURAIN skimmer overflow removes surface contaminants. Biological degradation is achieved with a combination of AQUALOOP growth bodies and aeration by AQUALOOP blowers. The treated greywater is then ultra-filtered through the AQUALOOP membranes and delivered to the clear water tank by the AQUALOOP station pumps. Bio-waste is periodically drained by the automatic sludge pump.

The economical and quiet-running RAINMASTER Favorit-SC pumps the  water from the clear water tank to the connected fixtures such as toilets, washing machines and irrigation systems. The RAINMASTER can operate in parallel by Bluetooth, ensuring the highest operational safety. If treated greywater is not available, the RAINMASTER automatically switches to a DVGW-certified mains water backup. For added piece-of-mind the treated and ultra-filtered greywater passes through a final disinfection step, ultraviolet irradiation through the in-line UV unit.

Your system

The modular and expandable system is designed for greater water needs in your commercial project. It is therefore also possible to install the system in underground or free-standing above-ground tanks. Indoor-tanks are pictured opposite.

Water Quality - Safety

INTEWA greywater systems deliver the cleanest water through the ultrafiltration
process.

Certified Safety
The INTEWA greywater system is the first and only system worldwide to be certified to both the NSF-350 Class C for commercial application and the British Standard BS 8525-2:2011 for spray application, the two most recognized and stringent greywater standards in the world.  

The RAINMASTER pump and control units are DVGW-certified, providing the INTEWA system the highest operating safety in the world.

fold faq

Complete system for up to 6 people with indoor tanks and RM Eco

Greywater recycling systems with free-standing tanks can be installed in most single family houses due to their small space requirements. For a single family house usually 2 x 300 Litre tanks are adequate.

for city-water tanks followed by headertanks

In many countries, municipal water is supplied only at certain times and therefore it must be stored. Often the quantity supplied is not sufficient. In such conditions, the installation of AQUALOOP greywater technology can be helpful. For instance, the treated water is used for the toilets, washing machines and watering the garden. It is topped up from the municipal water tank. Often the quality of the treated water obtained from greywater is better than that of the municipal water.
