Comminution technology has been evolving quite rapidly in response to the increasing burden entrained solids have placed on treatment facilities. More advanced devices have been developed in rapid succession. The result has been an exciting and fluid race between the leading manufacturers to develop the best size reduction device. The latest grinder innovations to be introduced have coupled the power of twin shaft grinding with higher flow capabilities and screw screening systems. Here’s a rundown on the past and present state of the art in wastewater solids reduction.

Here are some guidelines for everyday care, regular maintenance, and periodic calibration or replacement to assure optimum performance of pH instrumentation.

When it comes to water quality monitoring, professionals in municipal, industrial, and agricultural applications might have distinctly different concerns about what they measure, but they all share a common concern about the cost and ease of obtaining that data. Fortunately, a new alternative for achieving water quality data and analytics with a high degree of autonomy, accuracy, and affordability is now available to all of them.

Evansville is located on the north bank of the Ohio River in southwest Indiana. The City’s sewer system, parts of which are more than 100 years old, serves a population of 163,000, with combined sewers making up almost 40 percent of the total sewer area.

Young’s Cove is a masterfully planned exceptional waterfront community situated in pristine Prince Edward County, on the shores of Lake Ontario. It has panoramic views, a children’s waterpark, miles of pathways, green spaces. It covers 7,000 feet of shoreline and fronts protected wetlands and preserves hundreds of acres of forest with birds and wildlife everywhere.

From ragging and grit to odors and cost constraints, wastewater operators face persistent challenges. Proven headworks technologies and preventative maintenance help utilities improve performance, reduce downtime, and control costs.

When the Sanitation Districts of Los Angeles County (LACSD) were formed in the 1920s, the agency embarked on its first major project -- the construction of the backbone trunk sewer of the Joint Outfall System (JOS). Since then, the Sanitation Districts have completed many challenging projects, providing environmentally sound, cost-effective wastewater and solid waste management services to over five million people in Los Angeles County.

Maintenance professionals within Water and Wastewater Treatment facilities are as busy as ever. To keep up with growing demands on their time, they are always looking for ways to improve the reliability and maintenance requirements within their scope of responsibility.

ADM Cocoa Plant in Hazle Township, Pennsylvania needed help with their cocoa bean production. The plant processes two and a half million pounds of cocoa beans each day, turning them into cocoa powder, cocoa butter, and chocolate liquor. The company needed a machine to process sugar with over-sized lumps that could occur in transport or storage. Unless these agglomerated clumps were reduced to a granular form, the process could not work dependably. The machine also had to handle the large quantity of sugar processed daily and be sanitary.

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.

This application note from Aqua-Aerobic Systems highlights the effectiveness of the AquaStorm® Cloth Media Filter as a flexible, compact, and highly efficient solution for Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) events.

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

Industrial power plants or co-generation power plants utilize steam for industrial purposes other than power production.

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

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.

A municipal wastewater plant in North America sought a reliable flow measurement for one of their key wastewater lines. The existing dual-channel ultrasonic flowmeter from a competitor had consistently failed to provide accurate readings.

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.

A water management company in Serbia used Panametrics' ultrasonic flow meter technology for stormwater management, ensuring reliable measurement and accuracy in challenging conditions. The technology allowed for live monitoring of water transfer and reduced the risk of flooding.
