Our SOLVOX® systems help remove bottlenecks in water treatment by providing additional oxygen capacity for the activated sludge process. This can help water treatment operators overcome performance downturns as a result of overloading, short-term increases in influent or emergency situations.
Available as pure oxygen and air-oxygen hybrid models, our SOLVOX® range comes in a versatile design to fit any plant basin configuration. Our systems can be simply installed as part of a retrofit operation, without draining down, and are compatible with existing diffuser grids and surface aerators. Once installed, the equipment is easy to operate, fully automatic and flexible. Drawing on their vast process and design know-how, our specialists can help you design the optimum solution for your treatment plant. We support you every step of the way from process design and equipment build through installation and commissioning to pilot studies.
All SOLVOX® systems are offered with an oxygen supply scheme as standard, which, depending on your volume requirements, can be based on liquid oxygen deliveries or an ECOVAR® on-site generation system.
The SOLVOX® B submerged diffuser hose produces streams of fine bubbles from tiny pores along the length of the hose. No additional energy is required for the hoses and they can be used very effectively with existing aeration systems. The hoses are manufactured from a very stable chemical-resistant polymer that is also suitable for up to 20% ozone mixture . When the hose is under pressure, the holes expand to allow the passage of gas into the wastewater and when the pressure drops, the holes close up again. This is the most cost-effective solution for deep tanks.
Our SOLVOX® D in-line gas injection system is designed for use with pressurised pipes that convey wastewater. It uses a spherical-head nozzle to effectively disperse and transfer oxygen into the pressure pipes. This prevents sulfurous corrosion caused by anaerobic processes and provides a degree of pre-treatment by reducing the load on downstream stages.
The SOLVOX® V (venturi dissolver) jet mixer combines superior oxygen mass transfer efficiency with high rates of transfer. It has several operating modes, allowing oxygenation and mixing functions to be separated if required. This complete package comes with either liquid oxygen or an on-site supply scheme. The delivery of oxygen is fully automated and controlled by a dissolved oxygen sensor. SOLVOX® V is particularly well suited to activated sludge basins with lower water depths.
SOLVOX® R is a proven, versatile technology suited to drinking water and applicable wastewater applications. This series of pressurised reactors is the most efficient method of adding dissolved oxygen to primary treatment tanks, overloaded bio-filters and primary settlement tanks, delivering the power of oxygen with minimal turbulence and ultra-low off-gas volumes. The reactors can be installed in line or as a sidestream option and in closed tanks where access is limited.
Our SOLVOX® VITOX oxygenation systems are designed for more substantial upgrades and new builds, where high rates of oxygen transfer, good process mixing and process performance guarantees are required. These solutions are suited to fully mixed tanks, plug-flow or tapered aeration systems. They are permanently installed outside the tank and can be readily accessed for maintenance. Using extremely energy-efficient pumps, these custom-built solutions support wide variations in oxygen demand and mixing duties.
SOLVOX® VITOX comprises a venturi nozzle system with a pumped sidestream recycle pipework arrangement and distribution nozzles to ensure dissolved oxygen is thoroughly mixed throughout the activated sludge plant.
SOLVOX® W is a mechanical hybrid oxygenation system that can be used with pure oxygen, air or any combination of the two, depending on the requirements of the wastewater treatment process being upgraded. It can mix and oxygenate simultaneously, where required, and also mix without oxygenation. This hybrid unit works just as well with compressed air at low load, saving costs by adapting to load conditions.
