Biological Treatment Systems

Vogelsang are suppliers of Rotary Lobe pumps which are typically used in the waste water treatment sector to pump raw sewage and sludges, where the dry solid content is between 6% and 15% (by weight). Their use on an anaerobic digestion facility on a sewage treatment plant is very common application. The pumps are able to pass foreign bodies, can handle on a suction lift application (with a repeated self priming requirement) and are largely insensitive to dry running. The reversibility of the lobe pumps makes them suitable for membrane applications where running the pump in reverse allows for a cleaning of the membrane. We also offer inline RotaCut macerators and XRipper twin shaft grinders / shredders which are used to protect a downstream pump. These products too are in widespread use in the UK waste water treatment sector and are bespoke specified and manufactured to suit a specific application. The XRipper is suitable for both pipework and open channel applications and as with all of our products are robust and can be easily serviced by the end user without the need to remove it from site, ensuring the whole-of-life cost of ownership is minimised. We operate out of a facility in Crewe in Cheshire that has a comprehensive spares parts store. The company can provide both a field service and repair workshop service.

BioBox-E BV specializes in the development and realization of anaerobic digestion plants, along with advanced pre-treatment techniques for preparing organic substrates. This includes innovative methods for separation and size reduction to optimize materials for digestion.

For a full list of applications and for further details on key applications, follow the menu to the right. Cleaning systems The United Kingdom’s water industry is poised for its most ambitious transformation yet under the AMP8 (Asset Management Period 8) investment cycle, which runs from 2025 to 2030. Backed by an unprecedented £108 billion investment, the largest in the sector’s history, AMP8 is focused not only on maintaining and upgrading ageing infrastructure but also on addressing growing environmental and regulatory challenges. A significant £11 billion of this total has been earmarked specifically for stormwater and sewage spill mitigation, reflecting mounting pressure from regulators, the public, and environmental groups to curb pollution in rivers, lakes, and coastal waters. At the heart of this environmental push lies the urgent need for more stormwater retention tanks and combined sewage overflow (CSO) systems. It is estimated that some 2,000 such systems will need to be updated, refurbished or built in the AMP round of funding. This stormwater management infrastructure is vital if the target of reducing spills and sewage discharges into waterways by 44% is to be met. Much of this new infrastructure will require specialised cleaning systems. Storm water attenuation tanks can cause serious smell pollution if left improperly cleaned after usage. The StormBlaster tank cleaning system is a more effective alternative to tipping buckets, swirl eductors and manual entry cleaning. Screen cleaning Combined Sewer Overflows (CSOs) are a key feature of combined sewer systems, where rainwater and wastewater share the same pipework. During heavy rainfall, these systems can become overwhelmed without proper control measures. CSO chambers manage excess flows by allowing water levels to rise and diverting surplus into overflow pipes. A crucial component of CSOs is the screening system, which traps solids and keeps them within the sewer network. This prevents solid waste from entering local waterways and protects the environment. Foam control The formation of a stable foam in the water treatment process is a common problem. Foam can occur in aeration tanks, anaerobic digesters or secondary clarifiers. Foam is undesirable because it can overflow vessels, create slippery and unsafe working conditions, interfere with processing, damage materials, and cause tanks to drain and dry slowly. Controlling foam can be accomplished by spraying liquid onto the pool, vessel, or reservoir’s surface and allowing the spray’s droplets to impact the foam bubbles, causing them to break. Spray nozzle arrays positioned above fluid level can be used to knock back the foam and keep it under control. Odour control The use of sprays to knock down and neutralise odour is a common application for our spray nozzles. Nozzles are either used to directly treat odour particles in the air or as part of scrubber systems.
