Plant operators are challenged to maintain treatment throughput at reasonable cost even when the plant reaches design capacity. This challenge can be compounded by changes to production runs and formulation mixes, often requiring additional investment to maintain stable plant performance. However, extending plant capacity to maintain or increase throughput while handling a new mix is often prohibitively expensive.
Many operators are looking to support variable oxygen demand more cost-effectively and efficiently than traditional aeration techniques, which require energy-intensive air compression equipment. In addition, air only contains about 21% oxygen, making some conventional aeration techniques not particularly efficient as temperature fluctuates or influent load varies.
Pure oxygen for WWTP upgrades
In many cases, gas-enabled wastewater technologies are an effective way to balance conflicting cost, temporary capacity increase and compliance needs. Innovative, gas-based solutions are often a low upfront investment solution to inject new life into existing assets and extend their longevity. Often these technologies are also seen as a flexible way to bridge seasonal peaks in oxygen demand.
The biological treatment of industrial wastewater can be significantly enhanced through a secondary treatment stage with dissolved oxygen. Linde’s SOLVOX Mobile oxygen dissolution technology has been optimized for application of pure oxygen, additional process mixing and efficient oxygen transfer performance. The SOLVOX process results in excellent oxygen utilization performance and high transfer rates. Assembly and installation requirements are minimal, with little or no construction work required. SOLVOX mobile is ready to operate within a very short period and can also be installed in fully operational tanks, avoiding the cost and inconvenience associated with process shutdowns and drain downs.
Suitable for various operating conditions
Linde’s extensive range of SOLVOX products are suited to a wide array of wastewater treatment plants with different operating conditions. Regardless of the individual treatment challenges, Linde can enhance existing aeration capabilities by introducing pure oxygen into wastewater activated sludge in a variety of ways. Adding pure oxygen with the SOLVOX process can also increase the performance of an existing plant during peak loads and maintenance of main equipment. Requiring a very low investment, it offers a flexible way for operators to adjust to BOD or COD peaks and production campaign demands.
With its innovative concepts and developing technologies, Linde has a leading role in the global market. Traditionally driven by entrepreneurship, the company is working steadily on new high-quality products and innovative processes. Each concept is tailored specifically to meet its customers’ requirements, offering standard as well as customized processes. This applies to all industries and all companies regardless of size, according to a Linde spokesperson.
“If you want to keep pace with tomorrow’s competition, you need a partner by your side for whom top quality, process optimization and enhanced productivity are part of daily business,” the spokesperson says. “However, we define partnership not merely as being there for you, but being with you. After all, joint activities form the core of commercial success.”
Linde helps industrial plants and municipalities meet their wastewater management goals. We work directly with our customers to provide beginning-to-end treatment methods, from needs assessment and treatment strategy to equipment design, installation and carbon dioxide and oxygen supply.
