Bearing And Frictional Resistance: The Building Blocks Of A Restrained System

Connections bulletins PD-1 through PD-4 discuss some of the specific applications of the design of a properly restrained pipeline. PD-2 specifically addresses horizontal bends and the various parameters involved in the design process. PD-3 applies those parameters to the design of vertical offsets and tees. Finally, the design of reducers, dead ends, and miscellaneous fittings is discussed in PD-4. This bulletin delves into a more detailed discussion of the bearing and frictional resistance forces at work to balance thrust forces generated in pressurized pipelines. To see how this information relates to the various pipeline elements, please refer to the other Connections bulletins.

SCREENMASTER® CS Bar Screen To The Rescue At A Commercial Composting Plant

A commercial mushroom composting company in Pennsylvania needed help with a problem in their compost production process. The compost, made from hay, straw, horse manure, chicken litter, corn cobs and more, is processed on an eight-acre concrete slab, also called a wharf. The runoff from the rain and water used during the compost process washes off the wharf and into a pit and then travels through a pipe that carries it to the two-million gallon lagoon behind the wharf. From there, the company recycles the water by pumping it back to begin the process again. Unfortunately, the process wasn’t as smooth as they had hoped. Sediment and pieces of the organic material were continuously washing down into the pit and traveling to the lagoons, causing major clogs. This presented a serious issue for the company as it was slowing down their process, causing downtime, and making a mess of their lagoons. That’s when they contacted Franklin Miller for a solution.

N-Technology Impeller Pumps Eliminate FOG Buildup At Resort And Casino

The successful addition of new restaurants and clubs at a resort and casino in Upstate NY brought with them a flow of fats, oil and grease (FOG), which gelled into a floating blanket atop the main station’s wet well, where the sewage flows converge from the network of smaller stations throughout the property boundaries.

Appreciating The Importance Of Resiliency

As essential services, water and wastewater utilities face a lot of pressure to maintain continuity despite a variety of challenges — stormy weather, natural disasters, and even global pandemics. In-plant instrumentation, SCADA systems, and remote sensors all have their roles. But for more holistic views and higher-level analyses of performance patterns, an operational intelligence system can help to maximize resiliency.

Digital Twin Technology Helps Cincinnati Reduce CSO By 247 Million Gallons, Saving $38M In Capital Work

Pile Cloth Media Filtration For Food Processing

Read about the cloth media filter installations that have been operating in food and beverage wastewater plants for over 25 years.

Ion Exchange Resins Reduce Pollution From Refineries

A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

Application Bulletin: Reverse Osmosis

Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached

Advances In Paper-Based Devices For Water Quality Analysis

Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

Nitrogen-Reduction Treatment Systems For Long-Term Operations

The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.
