Ecomater uses rainwater for the production of potable water

For many years, Ecomater represents INTEWA for the Belgian market and successfully sells the PURAIN filter technique to many trading partners. Mr Van Der Cruyssen didn’t have to think about it for too long and he immediately installed the INTEWA AQUALOOP technique for his own building in Beervelde (Belgium). The installation happened quickly and without any problems. The produced rainwater was tested according to the German Drinking Water Ordinance. The quality is excellent and all the family members are very pleased. The system can be inspected.

 

Kandawgyi Lake is one of two major lakes in Myanmar. The lake is artificial; water from Inya Lake is channelled through a series of pipes to this lake. It was created to provide a clean water supply to the city during the British colonial administration. In October 2015 an AL-membrane system was installed to treat up to 2 m³/day to potable water quality.

House Versfeld, ZA

Treating household greywater & wash-down water for toilet flushing and irrigation.

Dr Andrew Versveld and family live on the beautiful Beaulieu Equestrian estate in water stressed Midrand area of Gauteng in South Africa. The AQUALOOP 4 membrane system treats up to 1200l of grey and wash-down water per day and stores it for later use in flushing toilets and for necessary irrigation around the property during dry spells and drought.

Application: AL-Membane Hlang River water treatment

Date of test: October 2015

Quantity of treated water: up to 2 m³/day

Greywater Recycling in Opawa

Greywater collected from the bathroom will be treated in the AQUALOOP greywater recycling system and then reused for flushing toilets and the washing machine. Rainwater collected from the roof of the house for primary use future proofs this dwelling for any events that may come. The integration of the AQUALOOP greywater recycling system saves between 30 - 40% of precious water and ensures that, in this case, the water stored in the tanks last for longer during dry spells.

Create potable water easily and economically with new water treatment technology.

The idea of a self-sus­tain­ing water sup­ply is not novel. In most cases, you will find these self-sus­tain­ing water sup­ply sys­tems in rural, un­de­vel­oped re­gions, which are catered ground­wa­ter. Un­for­tu­nately, every home owner does not have the same op­por­tu­nity to take ad­van­tage of such sources. Rain­wa­ter how­ever, is avail­able al­most every­where, but to date, it has hardly been used for any other pur­poses ex­cept for flush­ing toi­lets and wa­ter­ing the gar­den.

Ecobuilt home in Christchurch-NZ

INTEWA New Zealand - ALOAQUA provided ECOBUILT HOMES with the greywater recycling and rainwater utilization solutions. Including the design, technical support, supply of material and the commissioning. Installed in December 2014. This equipment supplied and commissioned by ALOAQUA ltd makes it probably the most water efficient house in Christchurch.

The launch of a new home in Addington, Christchurch has been welcomed by Mayor Lianne Dalziel. This eco‐home is certified with the highest possible rating of 10 stars in the Homestar ratings guide. It is the first home in New Zealand to achieve this perfect score. Mayor Lianne Dalziel notes that ‘this is important for Christchurch, for New Zealand, and actually the planet – because this is the future.

Pre-treated greywater is accumulated in the biological reactor which has a capacity of 1, 35 m³. The AQUALOOP kit is installed in the bioreactor, which is connected to the emergency overflow. Treated water is pumped to the second tank with a volume of 0, 6 m3. The RAINMASTER Eco 14 unit is a fully automatic operating and monitoring station combining pump, controller and built-in mains water top-up which is used for pumping treated water.

Christian Brothers Centre, South Africa

In case there is not enough rainwater available, or where there is not enough space for a large rainwater storage tank, the recycling of grey water can be the perfect solution to save mains water. Christian Brothers Centre in beautiful Stellenbosch, Western Cape, has just installed the first AQUALOOP water treatment system in South Africa. The learning facility, set on beautiful grounds dating back to the late 1700's, is rebuilding the old campus using sustainable systems. The Aqualoop collects greywater from one dormitory of 6 showers and hand basins and uses the clean, processed water for flushing toilets. In this project, the AQUALOOP components are installed in locally made corrugated steel tanks. Using this principle, the AQUALOOP concept provides a very flexible and cost effective installation. Local tank manufacturers are therefore able to build up their own water reuse systems locally.

Plant Testing Institute PIA, D-Aachen

INTEWA GmbH has appointed the Development and Assessment Institute in Waste Water Technology at RWTH Aachen University (PIA) to conduct practical testing of the AQUALOOP grey water treatment system designed for use in houses with up to 4 inhabitants.

PIA is certified to test waste water technology systems (according to DIN EN ISO 9001:2088-12) and is acknowledged as a European test centre (NB 1739) for the testing of various building products pursuant to the Building Products Act (Bau PG). Currently PIA is preparing for accreditation in NSF-grey water testing pursuant to NSF/ANSI Standard 350. The testing of the AQUALOOP system has been carried out at PIA between 03.05.2011 and 22.04.2012. The testing procedure included creating realistic conditions and high load levels. All required values (except BOD) were maintained according to NSF, even under extreme conditions and without a start-up phase included. The required BOD value can be easily achieved but only with a long start-up phase (adjusting biodegradation). This can be seen from test results of the other tested systems.

AQUALOOP MEM Field system waste water treatment plant AT-Salzburg

The technology behind the MEM / AQUALOOP systems comes directly from RHV Salzburg, the municipal waste water treatment plant for Salzburg and surrounding areas, in Siggerwiesen. The municipal waste water treatment plant operates using state-of-the-art technology and is a full biological waste water treatment plant with a capacity to handle the output from 680,000 inhabitants. The plant provides an ideal infrastructure for pilot tests to optimize membrane bioreactors and for executing other kinds of filtration experiments. An accredited central laboratory is located on site which provides data analysis of untreated and purified water in accordance with ÖNORM (ecological standards).

Two membrane process lines work in parallel with a partial flow of up to 10 m³/day. The tests run throughout the year. The pilot plants are equipped with modern apparatus as well as measurement technologies and operate fully automatically with SCADA and online data collection. The interpretation of data and access to control can also be done via UMTS.
