SUEZ has extensive expertise and experience in biowaste and biosolids management. Our proven technologies and customised solutions help industrial businesses meet their water, process water, wastewater and organic waste treatment challenges.
Energy can account for as much as 30 per cent of a wastewater plant’s operations and maintenance budget. SUEZ offers leading edge solutions to harness energy and other benefits from wastewater by-products.
Biological Hydrolysis (BH)
Our advanced BH technology is a flexible, multi-stage acid phase digestion pretreatment system that increases the efficiency of anaerobic digestion. Uniquely, the flexible system allows variation in temperature and hold times, enabling the production of a pathogen-free Class A biosolid that can be used as an alternative to synthetic fertilisers. It also enables:
Adding organic waste to the anaerobic digestion process helps increase biogas yields for conversion into renewable energy. Re:Sep is a multi-step process for organics separation that captures more than 95 per cent of organic material through high-efficiency separation of organic and contamination streams. The proven and robust system is capable of treating waste streams with contamination levels of up to 30 per cent, and even higher when throughput is reduced.
Re:Sep features a modular and scalable design to handle small or large flows of both liquid and solid waste, and produces an ideal digester feed substrate suitable for pumping, mixing and heating.
