Stricter discharge permits are being enforced, and some jurisdictions impose surcharges for high nutrient loads on publicly owned treatment works or direct industrial discharges.Where Traditional Treatment Approaches Fall ShortMany facilities rely on conventional aerobic treatment, lagoon systems, or activated sludge. While these reduce organic ...
Treatment processes span primary settling, biological or secondary treatment, tertiary polishing, disinfection, and sludge handling, each with its own mechanisms and efficiencies. Advanced monitoring and control systems, including sensors, automation, and data analytics, allow operators to optimize performance and identify issues early. ...
Unlike conventional systems, the process doesn’t rely on bubble aeration. Oxygen is delivered directly where it is needed. ...
Serving a quarter-million Portuguese, StreamLine® system upgrade improves SOTE, energy savings, and effluent quality Project Information Location: Lisbon, Portugal Company: The plant is owned by Loures SMAS and is operated and managed by SIMTEJO, which is a government owned company integrated with Aguas de Portugal (also known as Aguas do Tejo Atlantico). Plant Built: 1997 Population: ...
Challenge A wastewater treatment plant on the south side of Chicago had an extensive foaming issue caused by the Nocardia filament. All the aeration basins were completely covered and the foam even found its way into the center walls of the clarifier. 1.1 MGD activated sludge municipal treatment plant incoming BOD: 140-160 ppm incoming ammonia: 15-20 ppm. In addition to the foaming, the plant ...
System Activated Sludge Flow Rate 120,000 gallons per day Background The municipality upgraded their wastewater plant three years ago with finebubble aeration. ...
With a population growth of 24 million, Shanghai is truly the pinnacle of a 21st century city. However, accelerated urbanization rates pose significant challenges in the design and utilization of water and wastewater facilities. Older wastewater treatment facilities must be upgraded to cope with stricter discharge limits, as well as increased capacities. The Wusong facility, capable of treating ...
Introduction The City of Monticello, Indiana operates an extended aeration activated sludge treatment system to handle 1.6 MGD of flow. Up until 2019, the city had relied upon chlorination to control foaming caused by FOG filaments, specifically Microthrix parvicella. ...
If you have read the stalked ciliate entry in our microorganism database, you know they have an inverted bell-shaped head called a zooid, come in a variety of sizes, and fall into one of two distinct groups: those with a lorica (a shell) and those without. The database even touches on how both types have the ability to contract. But why do these organisms contract? While contractions are often ...
This Coca Cola bottling plant added a new bottling line that doubled its production that, in turn, doubled the organic loading to its activated sludge waste treatment ...
Location: Polymer Manufacturer, Texas Background: A water-soluble polymer manufacturer was having difficulty with an activated sludge treatment system that failed to meet permit limits. The treatment system was designed with an initial flocculation phase, whereby the pH was adjusted to 12 or above, followed by an anaerobic ...
Finally, the water is disinfected and released, and the remaining sludge is de-watered and safely disposed. Traditional biological treatment often uses activated sludge (where bacteria float in tanks) or trickling filters (where water trickles over a bed of rocks with microbes). ...
One of the biggest opportunities for saving money, one that is often overlooked, is reducing the energy demand of wastewater treatment systems. Traditional activated sludge systems, still the norm in many regions, are among the most energy-intensive infrastructure assets. ...
It’s often the result of complex microbial activity and biofilm development within the sludge system. That’s why a chemistry-based approach using Reactive Oxygen Species (ROS), delivered through JC-9465, has gained traction. ...
Manufacturing operations produce contaminated wastewater loaded with solids, chemicals, and organic matter that makes direct discharge or reuse impossible. Thankfully, wastewater is treatable using physical separation, biological digestion, and chemical reactions to remove contaminants at each stage. Progressive cleaning turns unusable wastewater into water clean enough for your processes or ...
This is achieved by utilizing processes like attached growth systems or suspended growth systems. Attached growth systems include fixed film systems such as trickling filters, rotating biological contactors, and submerged fixed-film and moving-bed bioreactors. Suspended growth systems include ...
In high-demand industrial environments, reliable, high-performance equipment isn’t a luxury—it’s a necessity. Gardner Denver blowers distributor C&B Equipment are engineered to meet the rigorous needs of operations across multiple sectors, offering dependable air movement and pressure capabilities that keep systems efficient, safe, and running at peak performance. We are ...
When nitrogen removal must be increased to comply with effluent regulations, Fluence solutions can update conventional activated sludge treatment systems Excess nitrogen in treated effluent is a key contributor to eutrophication in rivers, lakes, and coastal areas. ...
This is the second blog in our three-part series on essential nutrients for activated sludge. Specifically, these blogs aim to deepen knowledge on why carbon, nitrogen, and phosphorus are essential nutrients, and why the 100:5:1 C:N:P ratio exists. In the last blog we discussed nitrogen, how bacteria use it, how it’s removed from the ...
A containerised water treatment system is a compact, self-contained water purification solution housed within a secure, transportable shipping container. These systems are designed to provide efficient water treatment in remote or temporary locations, such as construction sites, mining operations, or emergency response situations. By integrating advanced water purification technologies into a ...
