Before wastewater can be treated to minimize biochemical oxygen demand (BOD), nutrients, and pathogens, it is important to eliminate as much debris as practical, as early on in the treatment plant as possible, to avoid clogging pumps or compromising downstream performance. Careful consideration of design and operating factors can minimize total lifecycle costs and maintenance effort while protecting screening efficiency.

Large, distributed water networks are not well-suited for conventional water monitoring processes which rely on manual sampling and lab testing. In particular, this midstream oil and gas company had a need to detect Iron, Selenium, and other heavy metals at a precise level comparable to a lab. In addition, it wasn’t feasible to manually test the entire water system at the requisite frequency. Finally, instrument reliability and unplanned downtime were an issue.

Sharjah Municipality of the Untied Arab Emirates (U.A.E.) was requiring to treat more and more flow despite having very little space for new treatment systems. They were looking at wanting to expand their plants No. 4 & No. 5 plants to meet new total nitrogen limits and try to do so by having to reuse the existing systems. This type of upgrade would save on cost as well as space at the plant.

To optimize the chemical dosage to precipitate phosphates from waste- water, an orthophosphate ion analyzer is used, equipped with a reliable sampling system. By Endress+Hauser, Inc.

In the mid-to-late 1800s, chlorine had been used sporadically to help control infection in hospitals and drinking water. Common water treatment did not start in the U.S. until the early twentieth century when increasing cases of waterborne illnesses prompted many large cities to begin large scale filtration of water supplies.

Despite their higher upfront cost, ceramic membranes deliver a notable return on investment while providing the same if not better water quality results as polymeric membranes.

It is more important than ever for cities and municipalities to leverage wastewater treatment plant data to optimize operational efficiency and sustainability, given the increase in energy prices and the rising frequency of severe weather events due to climate change.

A California winery was having odor problems from its wastewater evaporation lagoons. The wash and wastewater from this facility contain large amounts of organic matter. The wastewater is collected and pumped to two main lagoons for evaporation, percolation, and sprinkler irrigation.

Read how an Arkansas utility takes redundancy a step further with a permanent backup system to prevent sanitary sewer overflows. 

Now in operation for well over two years in the Malambo, Colombia, the Microclor® system has proven itself in terms of reliability and safety. According to management, the clear, vertically-oriented cells and the system’s open architecture allow for easy inspection and simplify any minor maintenance that might be required.

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.

Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

In the water and wastewater market segment, the LLT100 laser level transmitter provides an efficient way to measure levels of liquids.

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.

SensyMaster helps to improve the operating costs of the most cost intensive process in sewage plants: Aeration. High-measuring performance and state of the art technology helps customers increase plant efficiency.

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

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.
