7 Challenges Municipal Water Treatment Professionals Are Facing And How To Solve Them

Solutions that offer instant, chemical-free disinfection, manage costs, handle high organic loads, and control emerging contaminants are defining the path forward for water facilities.

Evaluating Bulk Hypochlorite Versus Hypochlorite Generated On Site

Chlorine gas is the historical disinfection choice for municipal potable water and wastewater systems due to its low cost and ease of maintenance. However, the hazardous status of chlorine gas and its potential as a terrorist target are driving many facilities to consider alternative disinfection methods. The decision frequently comes down to a choice between commercial sodium hypochlorite delivered in bulk (hypo) and hypochlorite generated on site (OSG). The primary decision factors are safety, cost, ease of maintenance, and environmental impact.

Clean Water Even During Disaster: Why U.S. Pipe Ductile Iron Pipe Is The Smart Choice For Public Health And Safety

Infrastructure must endure disasters to protect public health. Learn why ductile iron pipe offers fire resistance, seismic stability, and ensures clean, chemical-free water delivery when it is needed most.

Water Scarcity And Water Stress: The Difference And Solution

Understanding the difference and similarities between water stress and water scarcity is the first step in building a plan for a more sustainable, resilient water distribution system. 

Eclipse Gear Pumps For Chemical Dosing: VanLare Wastewater Treatment Facility

Located on the southern shore of Lake Ontario, the Frank E. VanLare Waste Water Treatment Facility, Monroe County, N.Y., has a total treatment capacity of 660 mgd and is currently running around 100 mgd. The plant uses Non-metallic Eclipse pumps to pump 12.5% Sodium Hypochlorite, Chlorine, for disinfection before the final discharge of the wastewater.

SPIRALIFT® Screening System- Solves Sludge And BOD Problems At City Of Plymouth

The City of Plymouth processes 150,000 gallons of raw sewage a day. Before 2009, the plant had no headworks installed at all. The raw sewage was being dumped into a pond. Because of this, the plant suffered major ongoing sludge and BOD problems. A city engineer recommended a new system be installed to combat these problems. After doing research, the engineer found a Franklin Miller system that proved a perfect solution.

Instruments For Environmental Applications

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

FLEX-TEND® Flexible Expansion Joints, Features And Specifications

FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

Sewage Lift Station Pumping System

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

Waterworks Joints 101

There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples Total bound nitrogen (TN_b) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TN_b measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters. By OI Analytical

Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing

With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

Automatic Scraper Strainers Protect Critical Membrane Systems

Automated scraper strainers pre-filter water and wastewater to protect fragile membrane systems from damage caused by large, suspended particles, reducing maintenance and replacement costs.

Optimizing Brine Flow In A Geothermal Power Plant

Different flow meter technologies were used in this geothermal power plant to monitor and measure brine. However, these traditional technologies failed. That’s where Panametrics PT900 Portable Ultrasonic Flowmeter was able to help.

Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water

As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.
