Products
Nereda®
Cost-effective nutrient removal in a compact space
Nereda® is the original aerobic granular sludge technology, offering an extremely cost-effective, efficient, and sustainable way to meet challenging effluent quality targets biologically, in a limited space.
Proven at full scale since 2005, and now with over 100 projects, Nereda® is enabling wastewater treatment plants on six continents to increase capacity, enhance nutrient removal, and reduce operational costs – while also reducing energy and chemical use.
Ephyra®
Better anaerobic digestion, in 80% less space
Ephyra® is an innovative sludge digestion technology for optimising anaerobic digester performance. The technology reliably accelerates sludge breakdown, increases biogas yields, and improves treatment capacity by 50-80% – all without pre-treatments, chemicals, or additional digesters. Proven in full-scale environments since 2017, Ephyra is suitable for retrofitting, as well as new-build plants, refining the anaerobic digestion process you already know.
Helea®
Efficient, low-maintenance AAD pre-treatment
First pioneered by Anglian Water, 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 – without the huge maintenance, installation, and fuel costs. After ten years of successful operation, it’s a proven, low-risk approach.
Kaumera
Kaumera Nereda® Gum, is a new bio-based resource which is extracted from aerobic granular sludge originated from the Nereda wastewater treatment process. This sustainable biopolymer is a valuable resource and a viable alternative to a variety of oil-based materials.
Kaumera offers a wide variety of applications, making it a versatile, environmentally and economically beneficial product for use in agriculture, the building sector, and the textile and paper industries.
Crystalactor™
Crystalactor™ is a proven crystallisation technology for purifying water and harvesting valuable resources.
The Crystalactor technology offers a sustainable solution for resource recovery from municipal and industrial water in the widest range of applications. The crystallization process purifies water by crystallisation of the target component and producing high-purity pellets. These pellets have proven to be reusable or for commercial resource recovery.
Twinn Aqua Suite
Operational optimisation and control of (waste)wat
Twinn Aqua Suite is an AI-powered software that helps utilities and industries gain actionable insight into their water and wastewater infrastructure to make better decisions, while performance is autonomously optimised.
Aqua Suite monitors, analyses, visualises and controls the performance of water and wastewater treatment processes through predictive analytics and machine learning.
Aurea®
Aurea® is the best-in-class technology for sustainable and cost-effective removal of micropollutants from (waste)water.
Aurea® synergically combines: biological activated carbon filtration followed by chemical oxidation. The biological process removes organic matter and a wide range of organic micropollutants, without activated carbon replacement. The chemical oxidation step, requiring minimal oxidant input, eliminates remaining recalcitrant pollutants. Aurea® ensures high removal efficiency for a wide spectrum of substances, minimizes energy consumption and CO2 emissions and leading to lower operational costs.
