Guardian Industries Corp.’s float glass plant in South Carolina was in search of a crusher to aid in their glass production process. They needed a unit that could break up the electrostatic precipitator material and prevent pneumatic transport plugs. Without the efficient breaking of these lumps, the process was interrupted, wasting time and money.

The plant manufactures touch panel and polarizer which are materials for LCD assemblies. Since the manufacturing process is a semiconductor process, the wastewater contains large quantities of organic solvent from developers, strippers and rinse liquid waste. By KLa Systems

The City of Palm Coast, located on the east coast of Florida, expanded their existing Wastewater Treatment Plant (WWTP) to increase capacity to 6.83 MGD due to population growth, as well as add the production of reclaimed reuse water for use within the City.

Most small towns, all over the world, utilize lagoons for treating their wastewater. Many rural industries also utilize lagoons for storm-water and wastewater treatment. While industrial plants may be able to pay for activated sludge treatment of one design or another, small municipalities simply do not have a choice in treating their small populations’ wastes.

Officials at the Jefferson Parish Sewerage Department approached the team at Digital Engineering to find a long-term solution for the odor and corrosion issues throughout the East Bank Wastewater Treatment Plant. 

As supplies of fresh water become increasingly scarce, methods of recycling and reusing this vital resource are getting more attention than ever before. Orenco’s AdvanTex Treatment Systems consistently produce clear effluent that meets the most stringent permit limits.

For water treatment decision-makers already sensitive to issues involving water scarcity, energy consumption, and environmental stewardship, the concept of sustainability is more than just a buzzword. It is becoming a means of survival in response to changing climate impacts, high energy costs, public scrutiny, and limited financial resources. Here is how better awareness, focus, and execution can make sustainability a reality.

Read about a wastewater treatment plant whose UV system was unable to reliably meet mandated disinfection requirements, and why it opted to switch to a chemical treatment solution. 

Making Waves spoke with Bing Liu, Sales GM of Xylem’s Water Infrastructure business in China, about the country’s growing water reuse opportunity and one utility leader that is leading the way: Beijing Drainage Group.

The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.

The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

Flex-Tend flexible expansion joints have a proven record of providing protection for pipelines subject to subtle or sudden movement. As with all products used in the water and wastewater industry, protection is optimized with the selection of the proper assembly incorporated into a sound design. This paper is intended to provide assistance in both of these areas.

A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

Stockholm water company produces biogas from their wastewater facility which feeds Scandinavian Biogas for energy production. As they need to accurately meter what they sell to the energy facility they used a project contractor firm to engineer and define the best solution for the project.

This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

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.

Pulsafeeder has secured a significant order for its NextStep series of stepper motor-driven metering pumps, specifically for use in advanced Reverse Osmosis (RO) applications. This deployment underscores the growing demand for precision chemical dosing in high-performance water treatment systems. The order includes NextStep NS1 and NS9 models, each selected for their unique capabilities in high-pressure and low-pressure RO environments.
