Summer can be a challenging time for wastewater treatment (WWT) plant operators. Higher temperatures place additional strain on facilities that are often already operating close to full capacity. By stimulating microbial growth and activity, a rise in temperature increases oxygen uptake and this can bring many operational and regulatory headaches. These include odor and foaming issues getting out of control, penalties for failing to meet environmental regulations and additional charges for effluent discharge. As a result, operators may struggle to meet their OPEX targets. In extreme cases, failure to comply with regulations can lead to plant closure and other sanctions leading to a severe impact on production operations, public reputation and, ultimately, profitability.
Oxygen-based aeration for business continuity
At Linde, we have helped hundreds of customers over the years to ensure smooth operations during seasonal peak loads and maintenance breaks with our SOLVOX
portfolio for wastewater treatment. SOLVOX uses oxygen to enhance capacity at competitive cost. It can thus keep your operation running smoothly during warmer temperatures and periods of instability without necessitating major civil works. Pure oxygen has a saturation rate in water that is nearly five times higher than that of air. This means that only a small volume of pure oxygen needs to be added to wastewater treatment processes to achieve the desired dissolved oxygen level. This avoids the high energy input and the associated foaming that excessive traditional aeration can cause. Building on customer feedback and the hands-on insights of our experienced teams, we are continuously improving our SOLVOX oxygen-based aeration technologies responding to the industry’s current challenges.
