  Introducing Claros Water Intelligence System From Hach
 

Changing regulations, unpredictable influent levels, and instrument downtime are all problems plant operators encounter. Without a clear picture of their water or data, operators face uncertainty about efficiency and compliance. Imagine the time savings, cost reductions, and peace of mind that a complete “water intelligence system” could provide. Claros™, the Water Intelligence System from Hach®, focuses on instrument, data, and process management to help reduce uncertainty and increase operational confidence.

Key Indicators Of Tube Settler Strength: Module Design And Construction
By Brentwood Industries, Inc.

There is a common misconception about tube settlers that thicker material, whether it’s thermoformed or extruded, yields a stronger, more structurally capable module. On the surface, this seems like a reasonable assumption. However, when we look at the details of module design and construction, we see that this is not always true.

Four Ways Ignition SCADA Speeds Development
By Inductive Automation

Have you ever been trapped in “development hell”? If you’ve been involved in developing software applications, you can probably relate to the feeling. Modern technologies offer many promising possibilities for your enterprise, but the actual process of development can feel endless and painful, especially for control engineers or other professionals who may not have extensive training in software development. In this white paper, learn about the development platform.

Protecting The Process: Pretreatment For Membrane Bioreactors
By Kevin Bates, JWC Environmental

Toward the end of the 1980s, Professor Kazuo Yamamoto from Tokyo University gave a lecture to a skeptical crowd. His topic? Immersed hollow fiber membrane bioreactors (MBRs). Since the day that first audience listened to the possibilities of MBRs, much work has been done to make membrane bioreactors a common step in the wastewater treatment process.

What Happens When Your SCADA Server Buys The Farm?
By Christopher Little, Trihedral

It is 3:00 am, and you are fast asleep at home in your bed. At your office across town, the server that monitors and controls your critical water and wastewater infrastructure goes offline. Maybe the hard drive failed or the power supply died. Perhaps it just lost connection to the network. Regardless, all polling, logging, monitoring, and alarming have ceased. What happens next?

Plant's Aeration Output Increased While Electricity Is Decreased
By Sulzer Pumps Solutions Inc.

Located in New Haven County, CT, the wastewater treatment plant in Meriden has a design inlet flow of 43,911 m3/day (11.6 MGD) with a maximum inlet flow of 143,386 m3/day (38.0 MGD). Upgraded in the 1960s and 1980s, the plant has been in existence since the 1800s. The plant initiated a series of major upgrades that had been approved to address its twenty-year growth.

New High-Performance (NHP) Series Membrane Bioreactor

The NHP Membrane Bioreactor module is an effective barrier against solids, bacteria, and viruses to deliver high-quality effluent for municipal and industrial treatment needs. Toray's advanced PVDF membranes, which have consistent nominal pore size (0.08 μm) and uniform distribution of pores, are densely packed into element blocks. This unique construction increases efficiency and decreases energy use during aeration.

Total Nitrogen New Method For Analysis: Webinar

Currently, the U.S. EPA has not promulgated a single method for the analysis of total nitrogen (TN). Most states that have TN regulations require permitees to measure TN as the composite of TKN, nitrate and nitrite. This approach is costly, time consuming, and susceptible to variability based on the methods used for the individual analytes. We are excited to announce the introduction of a total nitrogen test method consisting of a single spectrophotometric test kit.
