The wastewater pre-treatment plant processes effluent from the manufacturing facility prior to discharging into the sanitary sewer system for treatment at the municipal wastewater facility. Use of sulphuric acid to manage the pH of the wastewater in the buffering reactor tank prior to entering the DAF for solids and oil removal was considered to be an unnecessary risk requiring significant safety protocols.

The AquaNereda® Aerobic Granular Sludge (AGS) Technology is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. An aerobic granular biomass is comprised of compact granules that provide advantages compared to other secondary treatment processes.

Remote water shut-off valves and preemptive planning enable municipalities to protect water infrastructure and respond effectively during natural disasters, ensuring public safety and service continuity.

The pump stations at Monterey Regional Water Pollution Control Agency (MRWPCA) were having a problem with their channel grinders. The twin-shaft, drum-style channel grinders were used in the ten pump stations in the region that feed into the main Monterey Regional plant.

When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.

Learn about an easy-to-install system that works in conjunction with a variety of heavy duty motion sensing probes. 

The Little America West Hotel complex located near the town of Granger, Wyoming, used an outdated surface water treatment plant that provided poor quality water during storm events.

As a utility, it is tough enough to be notified that you need to remove a new contaminant of emerging concern (CEC). It’s even harder without having a complete picture of what is involved. 

When Kent County Water Authority faced the urgent replacement of a 94-year-old hydrant tied to a 1931 cast iron main, they were determined to maintain fire protection and avoid customer disruption.

Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. As they do so, these microorganisms deplete the amount of dissolved oxygen in the water, which can be deadly for aquatic species like fish that rely on dissolved oxygen to live. Because of this hazard to aquatic life, BOD is considered an adverse pollutant in natural waterways where healthy ecosystems are protected. Several states have identified BOD as a pollutant-of-concern related to runoff of stormwater from areas that are associated with industrial activities, and, as a result, have specified water quality limits or objectives for BOD in stormwater discharges from industrial facilities.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

Siemens offers to our customers the ability to make both process measurements, and to remotely monitor the activity and health of instrumentation, whether you have a SCADA, PLC or DCS system, or not. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.  

Strongly loaded organic industrial waste water, i.e. from sugar- or paper-factories, need to be pre-treated before determining the BOD value.

Precise pH control is critical in biomanufacturing processes to ensure product quality, consistency, and safety. This application note explores the challenges of pH management across bioprocessing stages and introduces Pulsafeeder’s NextStep pump as a reliable solution for accurate chemical dosing and process stability.

As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.
