Haskoning’s water technology products

GWI’s #1 breakthrough technology of the past decade, Nereda aerobic granular sludge is now delivering results for wastewater treatment plants on six continents.

A robust, single-tank version of the activated sludge approach you already know, it’s a fast, cost-effective, efficient, and sustainable way to meet challenging effluent quality targets biologically, in a limited space. No membranes or plastic support media, no clarifiers, and no anoxic and aerobic separation.

It can also be used flexibly with ferric salts, to meet tomorrow’s ultra-low nutrient targets with a far smaller chemical dose.

Proven in full-scale environments since 2017, Ephyra refines the anaerobic digestion process you already know to accelerate sludge breakdown, increase biogas yields, and improve treatment capacity by 50-80%. Without pre-treatments, chemicals, or additional digesters, it enhances output while cutting costs – typically achieving payback within three years.

Aurea combines the best properties of biological activated carbon filtration and oxidative treatment. This allows it to remove a wide range of organic micro-pollutants. Aurea has a low energy and resource consumption compared to reference technologies, resulting in low CO2 footprint and operational expenses. With the Aurea technology, you can achieve high chemical and biological water quality, enabling you to meet objectives such as the European Urban Waste Water Treatment Directive (UWWTD).

Helea is the simplest, cheapest, and most environmentally responsible way to pasteurise and hydrolyse your sludge. It’s a straightforward, low-maintenance way to enjoy the benefits of Advanced Anaerobic Digestion (AAD) – greater biogas yields and Class A quality in a limited space – while reducing capital and operation costs by 25-30%.

A natural biopolymer extracted from Nereda installations, Kaumera gives you the opportunity to create a new revenue stream while cutting sludge disposal costs – reducing volumes by up to 30%. As well as the extraction technology itself, we can help you establish buyer relationships, maximising the circular value of your wastewater.

If you’re treating hardness, heavy metals, phosphates, sulphates, or fluoride, you’re potentially disposing of valuable chemical resources. Crystalactor lets you extract them in a convenient, crystalline form, ready for recovery and recycling. It’s a proven, zero-waste process that’s compact and cost-efficient – and works in waste, process, and drinking water plants.

Combining continuous biological aerobic degradation of organic and chemical pollutants (BOD/COD), nitrification, de-nitrification, and phosphorus removal in a single looped system, a Carrousel® WasteWater Treatment Plant (WWTP) offers a cost-effective treatment solution with an optimal compact footprint.
