The cities of Littleton and Englewood, CO, just south of Denver, share a wastewater plant — the Littleton/Englewood advanced wastewater treatment (AWT) plant located in Englewood. The 7886 m3/hr (50-mgd) Littleton/Englewood AWT plant serves more than 300,000 residents in the Denver metropolitan area. The facility also receives sewage from 21 districts within a 75 square mile service area. Plant effluent is discharged to the Denver metro area’s major watershed, the South Platte River.

The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.

Modernize solids handling with automated aerobic digestion to manage rapid community growth. This high-rate process increases capacity, ensures Class A compliance, and significantly reduces disposal costs while providing odor-free operations through advanced nutrient and off-gas management.

Casey Whittier, product manager at Evoqua Water Technologies, answers the top frequently asked questions when it comes to phosphorus management.

The City of Warren Water Recovery Facility in Michigan, treats and protects the waters of the state. Read the full case study to learn how the City of Warren Water Recovery Facility has been able to attain accurate data at a high repeatability rate since the installation of the Promag W unrestricted mounting 0 x DN electromagnetic flowmeter.

For water treatment decision-makers already sensitive to issues involving water scarcity, energy consumption, and environmental stewardship, the concept of sustainability is more than just a buzzword. It is becoming a means of survival in response to changing climate impacts, high energy costs, public scrutiny, and limited financial resources. Here is how better awareness, focus, and execution can make sustainability a reality.

Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

Discover how stormwater detention tanks can aid in stormwater management, which involves reducing runoff into surrounding areas and improving water quality. 

As municipalities increasingly switch to vertical dry pit submersible pumps to address flooding concerns, one critical yet often overlooked installation detail can make or break system performance: baseplate grouting.

The City of Grand Rapids, MI sought out a partner to take responsibility for the operation and maintenance of the monitoring network including hardware, software, and data preparation.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

Siemens’ extensive portfolio includes various flow measurement technologies, such as Coriolis, clamp-on ultrasonic, vortex, and differential pressure meters, catering to a wide range of industrial needs.

Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached

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

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

Pulsafeeder has secured a significant order for its NextStep series of stepper motor-driven metering pumps, specifically for use in advanced Reverse Osmosis (RO) applications. This deployment underscores the growing demand for precision chemical dosing in high-performance water treatment systems. The order includes NextStep NS1 and NS9 models, each selected for their unique capabilities in high-pressure and low-pressure RO environments.

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.

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