The Lariana Depur wastewater treatment plant in Fino Mornasco, Italy, treats wastewater from multiple textile manufacturers in the Como region, known as the heart of the textile industry. Since 1994, ozone has been used effectively as a polisher to remove the dark blue-purple color — the result of the dyes used in the textile dyeing and printing process — from the water.

ABB’s AquaMaster4 Mobile Comms flowmeter is the latest wireless solution for continuous flow measurement, the logging of accurate data and communication of information that is critical for today’s water management.

Multicore turbo bowers with increased capacity now allow for larger wastewater plants to replace their outdated blowers with air foil bearing technology. Learn more about multicore blower technology.

A leading fruit juice company had expanded over the past ten years and increased wastewater flow from 7,000 to 11,000 gallons per day (gpd), without upgrading its wastewater treatment plant. Read the full case study to learn how after a Mazzei AirJection system was installed, dissolved oxygen levels increased in the aeration basins, which immediately eliminated the odors.

The Cypress Creek WWTP in Florence, AL, uses an extended aeration activated sludge process with a design capacity of 20 million gallons per day (MGD). Cypress Creek serves mostly residential customers, but about 15 percent of its influent comes from industrial sources, and their discharge to the plant contains large amounts of fats, oils, and grease (FOG).

There’s no good time to interrupt production at a manufacturing facility. For a worldwide leader in audio equipment, halting production for a facility maintenance project leading up to the busy holiday season was not an option.

Ozonation and biologically active filtration (O3-BAF) is being increasingly used to address the issue of organic micropollutants (OMPs) in wastewater treatment and potable reuse.

China Steel Corporation, a steel producer in Taiwan, produces wastewater that is high in organics, ammonia, solids, and other waste products. The wastewater is treated on-site using a series of biological treatment processes. The variable influent quality can make it challenging to meet treatment objectives.

The Topeka Water Treatment Plant (WTP) — a 60 million gallon per day facility - serves Topeka, Kansas and surrounding areas. Built in 1945, the plant underwent several renovations with the most recent upgrading the plant to its current capacity in 1993.

In 2015, plant officials decided to replace the first of the existing slakers and, after considering offers from several slaker suppliers, chose the A-758 PLUS™ paste-type lime slaker manufactured by Integrity Municipal Systems, LLC (IMS). Read the full case study to learn more.

Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

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.

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.  

A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

We arm municipalities with actionable data necessary to make informed decisions about water quality in their communities

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.
