SOURCE & DRINKING WATER TREATMENT |
|
|
|
By Myron L Company | Rising temperatures and precipitation combined with increasing nutrient runoff from human activity are elevating challenges in water treatment efforts. In some cases, that means increased threats to drinking water quality. In others, it means increasingly stringent nutrient discharge levels. Either way, taking the nutrient monitoring battle out to the field can help in waging a better fight at the treatment plant. |

Treating Trace Contaminants In Drinking Water | By Trojan Technologies | Many waterways contain environmental contaminants resulting from agricultural runoff or industrial/municipal wastewater discharge. Possible environmental contaminants include nitrosamines, pesticides, pharmaceuticals, personal care products, or other environmental contaminants. |

Pressure Data Is Critical To Predicting Distribution Systems Issues | By Sensus, a Xylem brand | Monitoring pressure at strategic points can provide valuable insight about potential leaks. However, this isn’t as easy as it sounds. The good news is that technology is available to gather pressure data that can be used to enhance service and improve asset management without a large capital investment by utilities. |

Rightsizing Blower Installations For Optimum Performance | By Aerzen | In regulated wastewater treatment plant (WWTP) environments, which require 100% blower system redundancy to satisfy the most extreme operating conditions, it can be easier to meet demanding physical thresholds than it is to refine energy performance to the ideal minimum. Here are some guidelines for covering all the bases — estimating the potential payback of balancing blower type, size, and turndown capacity while making the evaluation exercise worth the effort. |

Enhancing Treatment Capacity With miGRATE Technology At Verrado WRF | By World Water Works, Inc. | Due to rapid population growth in its service area, Verrado Water Reclamation Facility (WRF) in Verrado, AZ faced a challenge. Its existing treatment capacity of 1.54 MGD had become insufficient to meet the rising demand and comply with both total suspended solids (TSS) and total nitrogen (TN) permits. |

How To Extend The Life Of Your Wastewater Pumps | By Steve Craig, Fluid Components International | Wastewater treatment plants use numerous pumps in a variety of types and sizes to move water through the process. Depending on plant configuration, they may pump influent, activated sludge, thickened or digested sludge, biosolids, scum, filtrate, effluent, or reuse water. Each matrix has specific characteristics that engineers consider when designing pumping systems. |

Achieving Success: Leveraging The Manufacturer's Experience | By Huber Technology, Inc. | What is the typical design life of a wastewater treatment plant (WWTP) in North America? This is an important question to consider. Perhaps the better question to consider is: What is important to the operators and beneficiaries of a WWTP facility? |

| Silk-Based, Ultra-Fast Membranes Touted As 'Revolutionary' | A research team has developed a novel nanofiltration membrane using natural silk, which could revolutionize the process of water purification or treatment. While allowing beneficial minerals to pass through, this membrane rejects over 99% of organic pollutants in water, e.g., the notorious perfluorinated compounds. |
