Van de Kreeke Leidngtechniek’s new iPEK lateral inspection system ROVION SAT II makes inspecting laterals from the main sewer made easy.

In recent years, the robust growth of residential and commercial development in the Outer Banks of North Carolina has put a strain on many of the wastewater services in the area. The Monteray Shores WWTP in Corolla, at the northern end of the Outer Banks, was no exception.

Innovative work order management and mapping capabilities give municipalities insights on sewer work and crew progress. 

We approach challenges holistically to create cutting-edge, customized solutions. A crucial first step in this process is real world field testing. Why? Because distinct rubber compounds react differently in distinct waste streams. Given the unique chemical makeup of any waste stream, we can optimize rubber compounds, and by testing it in your unique application, we can design the proper aeration diffuser membrane materials needed for optimal performance and energy efficiency.

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.

Learn why data security, accessibility and quality are all crucial to successfully managing wastewater infrastructure and sustaining data hygiene.

Across many water-quality measurements — from free chlorine residual to disinfection byproducts, etc. — pH is an underlying factor affecting many water treatments and compliance testing results. Here are some guidelines for maintaining accurate pH readings to assure cost-effective treatment and final water quality despite changes in source water composition, treatment protocols, or other factors.

The New Harquahala Generating Project serves as a power and electrical wholesaler in the Southwestern United States. To fill the need for growing energy consumption in the region, this facility was built to provide power to the area.

The Picnic Point Wastewater Treatment Facility was faced with reaching their plant processing capacity. The plant was sending its biosolids to be incinerated and part of this challenge was to find a way to manage the biosolids produced by this facility. Hauling and disposing of this sludge was difficult and becoming expensive. It was desirable to have a Class A biosolid to alleviate this concern and be more environmentally conscious.

In regulated wastewater treatment plant (WWTP) environments, which require 100 percent blower system redundancy to satisfy the most extreme operating conditions, it can be easier to meet demanding physical thresholds than it is to refine energy performance to the ideal minimum. Here are some guidelines for covering all the bases — estimating the potential payback of balancing blower type, size, and turndown capacity while making the evaluation exercise worth the effort.

Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

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.

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

The 2000PV is a restraint for PVC pipe and the standardized mechanical joint. This product is the result of years of testing and evaluation and its performance has been proven by thousands of hours of proof tests, as well as third-party evaluations. This report describes the 2000PV through the 12" size.

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.

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.

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.
