The use of chlorine to treat and disinfect drinking water and wastewater has been in practice for decades, with the earliest recorded attempt dating all the way back to 1893. Since then, it has come a long way.

In processes where disinfection is required, chlorine is the most common and economic disinfectant, followed by sodium hypochlorite (liquid bleach). It is important to disinfect the RO feedwater to avoid fouling of the membranes, which results in poor performance and frequent cleaning.

ResinTech ASM-10-HP is a strongly basic hybrid anion exchange resin specially formulated to selectively remove arsenic.

The City of Crystal Lake, IL, was able to parlay a long-term solid relationship with a major pump manufacturer into a clogging solution for one pump station while achieving cost-saving standardization across its remaining pump stations, along with significant energy savings.

This is the second installment of a three-part series examining wipes in the waste stream. The first installment looked specifically at the growth of disposable wipes usage within the last decade. Now we’ll look at the public outreach campaigns and some of the ways pump manufacturers are adjusting their technology to try to reduce or prevent wipes-related clogging.

The X-PELLER is an S&L impeller upgrade that is specifically designed to pass high volumes of unusual trashy items through S&L pump stations. It is also available on new pump stations.

In regulated wastewater treatment plant environments, which require 100% 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.

A North Carolina hog grower with a brood barn of 200 full-grown sows contacted Reliant Water Technologies seeking assistance with one of his waste lagoons. The plan was to locate an aerator on one end of the lagoon and allow for the forward flow of water from a coarse bubble airlift to ‘push’ the water forward.

Despite electrocoagulation's demonstrated effectiveness, developing a reliable, low-maintenance reactor with sufficient water processing volume has proven to be a significant engineering challenge.

What began as a mandate to reduce water loss has grown into a model of smart water management for the Eastern Band of the Cherokee Indians (EBCI). Since deploying Kamstrup’s ultrasonic meters in 2016, the utility has transitioned from crisis response to innovation leadership — proving that even the most rugged terrain can support advanced metering infrastructure (AMI).

This article introduces how the WEAD hybrid system works and how it empowers AMR-based utilities with actionable intelligence immediately, shortening the road to full AMI.

Improper inspection can lead to inefficient repair methods, having you spend too much or too little to create a longer-lasting, impactful reduction in infiltration to your sewer collection system. At the very least, it creates the worst thing of all: distrust for the entire study.
