If you’ve been thinking that wireless technology for process control is still too far away or not as reliable as you would like for critical or hazardous applications in your plant, there’s a new reason that you might still want to evaluate it. Now you can get the best of both the “wired” and “wireless” world in a flow meter that let’s you read and send flow data with high reliability of conventional hard wire communications while at the same time simplifying maintenance and other routine tasks with wireless technology.

In today’s complex and frequently rugged process plant environments, liquid pumps are often over-worked and under-protected from adverse operating conditions. Many pumps run nearly non-stop 24-hours a day over multiple shifts. Poor operating conditions can reduce pump performance, require extra maintenance, shorten their lives and increase costs.

AktaKlor 25 solution is a USEPA registered 25% active sodium chlorite solution used in conjunction with additional precursor chemicals to generate chlorine dioxide. Chlorine dioxide is used in water treatment as an oxidant and a disinfectant.
This one's not on you, plant operators. Rather than a charge for utilities to aim higher in performance, the latest regulation to impact water treatment operations, as well as others, falls on equipment manufacturers — those who make pumps.
Name a contaminant, any contaminant, and chances are that the U.S. EPA’s new reference tool has you covered — or at least soon will. The recently revamped Drinking Water Treatability Database is set to include more than 200 contaminants, with detailed information on what they are, where they come from, and how to get rid of them.
The federal Lead and Copper Rule (LCR) is destined for changes attributable to hard times in Flint, MI, and the agreement from an EPA advisory council that lessons must be learned from the latest crisis.
For nearly a decade, public utilities that draw from surface waters have been contending with a developing regulation that is emblematic of the U.S. EPA and the systems under its charge.
The federal regulation for arsenic has been in place since 2002, and yet many utilities remain noncompliant. The culprit isn’t treatment capability, but cost. It happens that the most popular treatment technique is also quite expensive — but it doesn’t have to be.
Normally, when people hear the word ‘drought’ it’s thought of with a negative connotation. In the water business, however, that’s not always the case.
This edition of Disinfection Digest discusses the discharge limit of peracetic acid (PAA) into the environment and the incorporation of dilution factors in the assessment of a site-specific, risk-based residual PAA concentration in wastewater effluents.
pH measurement plays an important role in virtually every industrial process and an equally essential part in environmental regulatory compliance. Many of the below questions pop up every day whether in chemical processing plants, power plants, water and wastewater plants or biopharmaceutical processing.
This is the second installment of a three-part series examining wipes in the waste stream. The first installment looked specifically at the growth of disposable wipes usage within the last decade. Now we’ll look at the public outreach campaigns and some of the ways pump manufacturers are adjusting their technology to try to reduce or prevent wipes-related clogging.
Any operator will tell you that a treatment plant is only as good as its equipment. That means employing the devices with the longest lifespans, the lowest operating costs, and the most intuitive designs is critical.
