Wastewater Treatment Insights

  1. The Improved Business Case For Membranes In Industrial Water Reuse 2/13/2020

    Membrane filtration can be a valuable tool in industrial operations by removing oils and solids that are generally not captured with other bulk separation methods. However, membranes have traditionally been limited by low throughputs, poor durability, and the inability to consistently achieve low residual oil levels. The good news is advanced membrane filtration technologies that promote efficient and economical water reuse are now available.

  2. Microwaving Sewage Waste May Make It Safe To Use As Fertilizer On Crops 1/29/2020

    Biosolids — primarily dead bacteria — from sewage plants are usually dumped into landfills. However, they are rich in nutrients and can potentially be used as fertilizers. But farmers can’t just replace the normal fertilizers they use on agricultural soil with these biosolids. The reason is that they are often contaminated with toxic heavy metals like arsenic, lead, mercury and cadmium from industry. But dumping them in the landfills is wasting precious resources. So, what is the solution?

  3. Water Scarcity In Texas: Rushing Ahead Of Science Could Scuttle Solutions 1/28/2020

    Water scarcity is a challenge facing many Texas communities, and it’s encouraging to see how many state leaders are proactively exploring solutions to our growing water needs. This has brought the oil and gas industry and the massive volumes of water it uses and produces each year into the conversation.

  4. How Food And Beverage Companies Can Get Ahead Of The Water Scarcity Curve 1/23/2020

    High-quality water is critical to food and beverage production — both as an ingredient and a process enabler — so the sourcing challenges faced by municipal water systems pose an ongoing threat to the health of the industry. Fortunately, there are a variety of technology options now available to improve water security.

  5. Sustainability Trends In The Water Industry: A Focus On Microplastics In Wastewater Treatment 1/21/2020

    Plastic has had tremendous impact on society in ways both large and small, such as with microplastics — tiny substances creating a huge problem.

  6. The Future Of Collection Systems 1/21/2020

    As real-time monitoring continues to infiltrate the water industry, it’s time to apply such instrumentation to detect the other type of infiltration — along with inflow, snow and ice melt, etc.

  7. Quantitative Analysis Of Onsite Wastewater Treatment System Environmental Impact 1/21/2020

    Environmental protection is at the heart of wastewater treatment, but the treatment system itself has a footprint. Here, a comparative analysis of the resource consumption of conventional and recycled thermoplastic systems is provided.

  8. Sidestream Enhanced Biological Phosphorus Removal Made Easier 1/21/2020

    Some excellent progress has been made in recent years on sidestream enhanced biologic phosphorus removal, but a current project promises to advance the practice even further.

  9. Waste Not, Want Not — Turning Wastewater Into An Asset 1/21/2020

    Every water project is different, but each one also provides lessons for others, such as this profile of a Southern California reuse project where conveyance needed to be routed around a protected environment.

  10. Microalgae — A Natural Answer To Purifying Wastewater 1/21/2020

    Algae is a major problem for many wastewater treatment plants and water managers. It may also be a solution.
