Our story
Byosis was founded in 2009 with the aim to develop new technologies for digestate treatment for Waste-to-Energy sites. In 2022, we became part of NSI, Saur Industrial Water Solutions division.
Gradually we diversified into other markets and have become active in municipal and industrial wastewater solutions, where we offer an attractive alternative for reducing ammonia before an aerobic biological treatment step. This helps to reduce the carbon footprint (by reducing N₂O emissions and recovery of nutrients that would otherwise be destroyed) and enables a flexible operation.
Apart from the supply of the unit we offer supervision during erection, commissioning, performance tests and project management during the entire project. After handover you can choose from a range of services such as periodic inspection, training, helpdesk, remote support and ordering and delivery of spare parts.
Focus is to create complete solutions with our NSI partners with a customer for life approach.
Our ambition is to offer the best value for money to customers who value the principle of Total Cost of Ownership.
Our solutions
We offer standardized solutions to recover resources from digestate and wastewater.
Ammonia stripping and recovery
ByoFlex®: Ammonia stripping and recovery unit for polluting substrates such as (sludge) digestate with high % of solids (suspended and dissolved). The solution can be configured to meet any demand and is very energy efficient and no alkaline needs to be added. The ByoFlex® comes in standard configurations with a throughput of 5, 10 and 20m3/hr to be combined for more throughput (>80m3/hr). The ByoFlex® is also available as a demonstration/rental unit. Check the ByoFlex® page for more information!
Pasteurization
ByoPast®: A modular and complete continuous pasteurisation solution for large throughputs ranging from 10 to 60 m³/hr and any multiple.
Additional equipment
- Heat exchanger: a special tube-in-tube heat exchanger unique due to its modular nature. The heat exchanger can be designed to meet any demands (heating, cooling, heat recovery) and is designed for viscous and polluting substrates.
- CIPR®: A containerized or skid mounted modular CIP system (clean in place) for the heat exchanger and heat recovery tubes.
The Byosis Service Level Agreement helps clients to obtain the best possible performance and reliability of your installation with maximum availability. We provide three main services:
- Service desk: The advantage of direct access to the Byosis service desk gives quick availability of a Byosis technician or specialist in the situation of an operational-, process- or technical problem. First, we check whether the problem can be solved remotely. If the problem cannot be solved remotely, we can provide quick on-site assistance (depending on your location). We can also assist you with providing spare parts and fast delivery in case of a breakdown or calamity. We also keep critical parts in stock, which can be quickly shipped and/or replaced in case of failure.
- Remote inspection reports: The installation will be at least weekly monitored. Analysis of alarms and process deviations are filtered out. Periodical reports are shared with a summary of essential parameters and findings. Due to the extensive installed base of Byosis, we have a wide range of experience and knowhow about operating the ByoFlex installation(s) as efficiently and reliably as possible.
- Site visits: During 2 working days, the complete Byosis installation is checked by Byosis technicians on the general conditions, safety and performance. During an additional day, feedback and advice is provided. Additionally, training is provided to operators and questions will be answered and followed up. After the visit, the analyses are assessed in consultation with our specialists and the results and recommendations are processed and shared via a site visit report.
