The Selection & Use Of Sludge Muncher Grinders & Wastewater Munchers

Sludge grinders are inline processors that play an important role in the successful operation of wastewater treatment plants by reducing oversized solids that can causing jamming and damage to pumps and process equipment. Franklin Miller grinders are known for their heavy-duty capabilities and innovative designs with models available for a variety of application requirements.

Retrofitting Water Systems With The Best Meters For The Job

Although not every water, wastewater, or industrial design engineer or operations manager is familiar with the advantages of the V-Cone differential-pressure (DP) meter design, they are certainly familiar with the problems it can solve. Here is a step-by-step description of how V-Cone meters with + 0.5 percent accuracy offer better alternatives in applications currently being failed by other metering technologies.

Decoding Ozone Disinfection Revisited

Late last year we published an extremely popular article on understanding the ozone disinfection process. Based on the response, we’ve updated this year’s article with a bit more information to illustrate how powerful these simple tools can be to operations staff.

Abbottstown Retrofitted A Flow-Through System With An AquaSBR® System To Meet Stringent Effluent Requirements

The Abbottstown-Paradise Joint Sewer Authority was incorporated in 1973 and utilized a continuous flow activated sludge system with an average daily design flow of 0.21 MGD. At that time the plant was only required to reduce total suspended solids (TSS) and effuent ammonia to required levels to serve the area population of about 2000. Due to urban growth and increased storm flow runoffs, the plant was in need of an expansion and upgrade by the late 1990s. 

Phosphorous Solutions For Wastewater Treatment

This paper presents a comprehensive overview of technologies for phosphorus removal and recovery, including chemical and biological processes, ballasted clarification, filtration, and nutrient recovery.

Crusher Takes Its Lumps, Minimizes Elbow Grease

CCP, Inc. in West Paterson, N.J. makes over 1,000 product formulations under private labels for the cosmetics industry, using materials such as persulfates, alkali silicates, phosphates, sodium chloride, and magnesium chloride.

Pilot Studies In North Carolina With Hydrex™ Odor Solutions

Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H₂S atmospheric concentrations of 300-500 ppm. Both clients desired H₂S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

Aerated Biological Nitrogen Removal

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

Application Note: Small Team Saves Big Hassles With The Professional Plus Multiparameter Instrument In the past, Shinkle and her colleagues carried separate YSI meters for pH and DO, she notes. Now they use the YSI Professional Plus handheld multiparameter instrument, which allows them to measure pH, DO and temperature with one quick, reliable instrument. By YSI

Determination Of Polycyclic Aromatic Hydrocarbons In Seafood

Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

Why Measuring Hydrogen Sulfide In Wastewater Matters

Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.
