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.
