Wastewater flows in seasonal resorts are highly volatile. Learn how to stabilize biological treatment against sudden peak demands and low-flow off-seasons, ensuring continuous compliance and securing a high-quality water source for reuse.

Following Tropical Storm Isaias, a damaged reservoir outlet pipe needed fast, custom repair. Learn how a quick response, site assessment, and custom-engineered couplings prevented a major water service shutdown.

After twelve years of operation, a modernization of a WWTP was needed for the removal of nitrogen and phosphorous pollutants, as well as an enlargement by another 100’000 PE (population equivalent).

Grit buildup that is ignored or improperly addressed can have profound effects on both treatment efficiency and maintenance costs, even if it does not impact effluent quality. Here are some of the cost implications and physical effects of inefficient grit removal, along with some important considerations on the impacts of letting grit go unmanaged.

Reduction of ragging is merely one of the benefits the EscaMAX® Perforated Plate Screen bestows upon its implementer. But this is such a huge factor, that mitigating it brings night-and-day results in other areas such as reducing debris in the grit channel, increasing space for energy-producing biosolids in tanks, and releasing cleaner end products. 

At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent

This article focuses on the use of electromagnetic flowmeters in the W/WW industry. It also covers Endress+Hauser’s capabilities to manufacture electromagnetic flowmeters from 1/12” to 120”, calibration, the company’s new innovative sensor with multiple sensing electrode pairs and verifying calibration in place after installation.

In response to Hurricane Harvey, the Fort Bend, TX Levee District No. 2 embarked on a major upgrade project to increase the flow and capacity of one of its pump stations by 400%. The goal of the project was to protect the area around the district from 100- year floods in the future.

Did you know that just one gram of granular activated carbon (GAC) can have a surface area equivalent to several football fields? 

A water reclamation facility in Carol Stream, Illinois, optimized its equipment layout using Blue-White’s FLEXFLO® M2 metering pumps and CHEM-FEED® wall mount systems, improving functionality, reducing piping complexity, and saving space for a more efficient operation.

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

To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

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