Individual Multi-barrier systems

Typically, multi-stage treatment processes are necessary to ensure that drinking water from ground and surface sources remains consistently suitable for human consumption. These processes also address issues related to storage and distribution in the network.

At WABAG, we have extensive expertise in designing and implementing these multi-barrier systems, derived from our experience gained through numerous projects. We excel in providing optimal solutions by combining conventional processes with advanced technologies like advanced oxidation and membrane filtration. This approach ensures a high level of flexibility and delivers water of the highest quality standards.

Our executed projects range from conventional large-scale drinking water treatment plants with capacities of around 400 MLD to individually designed WTPs tailored to specific requirements, such as biological denitrification plants for groundwater treatment.

Securing safe drinking water: the ambitious Kavaklidere Water Treatment Project in Izmir, Türkiye 

Kavaklidere WTP, Izmir, Turkey, 360 MLD

Ensuring safe drinking water supply for 2 million people.

An ambitious project was executed in Izmir for drinking water production with a maximum flow of 401,500 m3/d. The water from the barrage lake is purified in a multi-stage process, including aeration, ozonization, clarification, filtration, disinfection, and sludge dewatering. The project was executed on a turnkey basis and included civil and demanding excavation works.

Capacity:            360,000 m3/d, max. flow: 401,500 m3/d

Technology:      multi-barrier systems

Start-up:            2019

Setting new standards in drinking water treatment: innovative groundwater treatment in Muttenz, Switzerland–

A three-stage water treatment plant employing cutting-edge technologies guarantees maximum safety and conserves resources.

Muttenz, situated along the Rhine near Basel, relies on groundwater for 80% of its drinking water, affected by Rhine infiltrate leading to micropollutant contamination. To address this, WABAG developed an innovative treatment process—combining extended oxidation (HiPOx process), activated carbon adsorption (the WABAG PACOPUR®-process), and ultrafiltration—implemented in the new Muttenz WTP to ensure optimal water quality and safety amidst industrial and environmental challenges.

Here, for the first time, powdered activated carbon is continuously added and removed again using ultrafiltration technology in a Swiss drinking water treatment plant. In order to minimize the consumption of powdered activated carbon (PAC), WABAG has additionally developed and patented a PAC recycling system.

Capacity:       19,200 m3/d

Technology: Advanced oxidation, GAC and PAC adsorption, Ultrafiltration

Treatment of Nile water for safe drinking water supply: El Raswa WTP, Stage II at Port Said, Egypt

The growing population of the city of Port Said demanded an expansion of the existing drinking water treatment and supply system complex near the Suez Canal to ensure a safe water supply. WABAG has built a new water treatment line with a capacity of 80,000 m3/d. The new WTP employs a multi-stage treatment system, including sedimentation, filtration, disinfection, and powdered activated carbon (PAC) dosing at the flocculation stage. The raw water turbidity of up to 35 NTU is reduced to less than 0.4 NTU. The plant was commissioned in 2020 and operates fully automatically.

 Capacity:            80,000 m3/d

Technology:      Flocculation & sedimentation, PAC dosing, filtration and disinfection.

Start-up:            2020
