Stormwater systems must evolve for extreme weather. Submersible pumps, compact designs, and digital modeling help build resilient infrastructure capable of handling future flood challenges.

PASS is a workflow for understanding sewer system conditions quicker, with fewer resources. 

Ferrán Bosch, Senior Business Development Manager Xylem Vue at Xylem, speaks with Koldo Urkullu, Director of Operations and Asset Management at CABB, about how a utility is innovating to meet volatile weather patterns head-on. 

As municipalities worldwide look to reuse water for agriculture, industry, and tertiary treatment such as filtration and disinfection prior to discharge or reuse for irrigation or industrial purposes, one inconvenient truth continues to lurk in the pipes: chlorine.

Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits.

In this article, Lance Thibodeaux, division manager for the Terminal Island water reclamation division at LA Sanitation and Environment, describes Terminal Island’s industry leading water reuse program and its long-time partnership with Xylem.

Pronal, a recycled paper plant, produces craft paper. The plant produces an average flow of 14,000 m3/day (3.7 MGD) of wastewater with high contents of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS).

As water reuse becomes a critical part of water security, municipal water utilities will increasingly be under pressure to incorporate cost-effective reuse schemes in their daily operations. It's time for a new solution. 

Jet aeration retrofits modernize aging wastewater tanks with minimal downtime, integrating easily into existing basins while delivering long-term reliability, higher oxygen transfer efficiency, and significantly lower lifecycle costs.

Wastewater treatment plants are facing a more challenging influent environment than ever before, making effective inlet screening a much higher priority. Extreme weather is driving bigger and more frequent peaking events heavily laden with plastics and other non-biodegradable debris, while modern waste stream challenges like flushable wipes, pharmaceuticals that bind to solids, fats, and oils that form fatbergs, and a growing load of non-dissolvable materials are overwhelming systems designed for a bygone era.

The Biochemical Oxygen Demand over a testing period of n days (BODn) is precisely defined and associated with experimental standards. It represents the quantity of oxygen aspirated in the course of aerobic breakdown of organic substances by microorganisms.

In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.

This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.

A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past.
