Kansas Wastewater Treatment Plant Makes A Long-Overdue UV System Upgrade (Case Study)
Kansas Wastewater Treatment Plant Makes A Long-Overdue UV System Upgrade (Case Study)

The UV disinfection system at the Plant 20 Wastewater Treatment Plant was installed in 2002, but over the years staff continued to struggle with PLC and controls-related issues, ballast failures, and water level management. An overhead crane was needed to operate the water level management device, and water level fluctuations of 12” were common, which contributed to an increase in fouling on the quartz sleeves.

Methanol Dosing Technology Helps Denitrification System Pass Rigorous Performance Test
Methanol Dosing Technology Helps Denitrification System Pass Rigorous Performance Test

In 2007, Greenville, SC-based Western Carolina Regional Sewer Authority (WCRSA) conducted a rigorous performance test on a new tertiary treatment technology to assess its ability to effectively remove nitrate-nitrogen (NO3-N) without using excess amounts of methanol at its Lower Reedy Wastewater Treatment Plant (WWTP).

OMNIFLO® Sequencing Batch Reactor (SBR) MAX System OMNIFLO® Sequencing Batch Reactor (SBR) MAX System

Evoqua's OMNIFLO® SBR MAX system with Jet Tech technology combines the benefits of a true-batch SBR with the benefits of a continuous fill batch reactor process to treat wastewater influent flows to over 5 times design.  The OMNIFLO SBR MAX system optimizes hydraulic handling during storm flows, reduces equipment sizing and cost, and can trim energy costs over 15%!

Aspiral™ Packaged Wastewater Treatment Solution (MABR) Aspiral™ Packaged Wastewater Treatment Solution (MABR)

Aspiral™ is a smart, packaged wastewater treatment solution based on the Membrane Aerated Biofilm Reactor (MABR) technology.

Next Gen Capital Controls® Chlorinators Next Gen Capital Controls® Chlorinators

The unique compact design incorporates the best existing Capital Controls® technology with exciting new features. With just three models ranging from 10-10,000 lbs/day capacity, each chlorinator is available with automatic or manual feed and a 10” flowmeter for an easier read. Sonic operation on the 4100 model eliminates the need for a differential pressure regulator. On all automatic models, an additional controller isn’t needed, reducing components – and costs.

Capacitive Deionization Takes Off Capacitive Deionization Takes Off

Capacitive deionization (CDI), sometimes called electrochemical demineralization, is referred to as Radial Deionization (RDI) by Atlantis Technologies, which has developed a proprietary form of the process. If you haven't heard of it by any name, or would like to know more about its considerable treatment capabilities, tune into this interview with Patrick Curran,

The Expanding Role Of Ozone The Expanding Role Of Ozone

As water reuse becomes increasingly common, more utilities will get to know ozone. To explain its role in water treatment schemes, Water Talk welcomed Jim Lauria, Vice President of Sales and Marketing at Mazzei Injector Company, and Ben Kuhnel, Senior Project Manager for Arcadis. Learn how ozone works in concert with other processes to safely recycle water and treat contaminants of emerging concern — even in mobile/on-site applications.

A Fresh Look At Membrane Bioreactors A Fresh Look At Membrane Bioreactors

Membrane bioreactors (MBRs) are not new, but they are the subject of renewed interest among utilities, and for Carollo Engineers Vice President Andrew Gilmore. He sat down with Water Talk's Todd Schnick and Kevin Westerling to discuss the MBR renaissance and the reason for their rise in popularity.

Ozonia M and FiltraFast Provide New Options For Treatment Facilities Ozonia M and FiltraFast Provide New Options For Treatment Facilities

If you don’t need the performance of an ultrafiltration membrane but also want to avoid the large footprint of a conventional media filter, you might want to consider FiltraFast extreme rate compressible media filters. As Ryan Hess, Director of Advanced Separation with SUEZ Water Technologies suggests in this Water Talk interview, “They provide roughly ten times the hydraulic loading rate of conventional media filters.”

Getting Chlorine Disinfection Right Getting Chlorine Disinfection Right

Of all the process considerations facing wastewater treatment operators, disinfection is one of the most important. In this exclusive Water Talk interview, Gary Lohse, Technical Sales Manager, Disinfection with De Nora Water Technologies, discusses how disinfection has become increasingly complex over time. Lohse reviews a host of selection criteria including target microorganisms, control strategies, disinfection by-products, capex and safety.

Drumming Up Chemical Injection Drumming Up Chemical Injection

The operating ranges for chemical injection need to be large because of the variability of flow in many treatment operations. As Bill McDowell, Vice President of Operations with Blue White Industries explains in this Water Talk interview, “You might be down to as low as 5 or 10 milliliters a minute and then one hour later; you might need to pump 15 gallons a minute out of the same pump and through the same sensor.”
