Should You Trash Your Flow Meter?
Generally speaking, market research reports aren’t terribly exciting reads, but they are at times enlightening. Studies on how specific technologies are being applied can reveal trends for the industries they serve — for example, flow meters in water and wastewater. I recently came across some interesting analysis on the subject, homing in on what they reveal about our corner of the world.
5 Standout Membrane Technologies
Membrane technology, highly significant for surface water treatment, desalination, and wastewater reuse, is poised for major impact due to the dwindling availability of water. Here are five featured technologies to put on your radar.
Nutrient Removal: Is Bardenpho Right For You?
The Bardenpho process is a popular choice for biological nutrient removal (BNR) of phosphorus and nitrogen, but it requires tankage that not all wastewater treatment facilities can accommodate. This case study details the process, the necessary plant parameters, and the performance of Bardenpho.
What Are The 3 Biggest U.S. Water Challenges?
Social media discussions can be hit or miss, but a recent one in particular caught my eye with the question: “What do you believe are the three biggest water challenges in the U.S.?” The informal survey drew great response, and a surprising number-one answer.
Pump Power: Are You Getting Bang For Your Buck?
It’s no secret that municipalities are working under tight budgets, in no way commensurate to their responsibilities and objectives. Unfortunately, the purse strings likely won’t loosen any time soon, and so efficiency becomes an essential part of operations.
