Waste Lagoon Rehabilitation A New Look At An Old Problem

Throughout the last half-century the municipal and industrial wastewater treatment industry has depended heavily upon the use of waste lagoons in order to provide relatively clean water that could be returned to the environment. These are often called stabilization lagoons.

Can Heavy Rain Cause Sewer Backup?

Heavy rain is a fact of life in most areas around the world. While it can be refreshing and calming to see, it also brings with it a number of issues that have to be considered. 

Liquid-Only Sewers Offer A Cost-Effective Solution

Liquid-only sewers have proven to be a cost-effective solution for municipalities, new subdivisions, and a variety of other areas in need of sewer -- as opposed to the big pipes and deep excavations.

The Importance Of pH Levels In Water Treatment

Recognizing pH's pervasive influence empowers operators to achieve consistent and reliable outcomes in every facet of water and wastewater treatment, underlining its indispensability for clean and safe water systems.

Electroplating 1 (CrVI, Ni, Zn, Cu)

XXXX Plating Company operates a decorative plating shop in Los Angeles, Ca., doing finishes in nickel, copper, and chromium.

Ushering In A New Era Of Sustainable Biological Treatment

Conventional activated sludge treatment for wastewater is becoming increasingly problematic over time. Not only does the process require significant amounts of energy, which drives up operating expenses, but utilities are under mounting pressure from the U.S. EPA to go green.

ORP And pH — What You Don't Know Can Hurt You

When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.

How To Optimize Conveyance Systems For Debris Management

There are many different types of conveyance technologies, including sluices, screw conveyors, belt conveyors, and more. The right technology for an application depends on a vast number of factors.

Odor Problems Solved At Santa Margarita Water District's Chiquita Water Reclamation Plant In Orange County, CA

Santa Margarita Water District (SMWD) is the second largest water district in Orange County, California, providing water and wastewater services to more than 155,000 residents and commercial enterprises. When a new housing development was planned adjacent to SMWD’s 9.0 MGD Chiquita Water Reclamation Plant, the District initiated plans for enhanced odor control solutions. District staff identified the primary process area (grit removal and primary clarifiers) as a significant contributor to odor emissions.

Two Products Combine To Provide An Enhanced Nutrient Removal Advantage To Protect Our Waterways

Cherokee County, GA, conducted an extensive on-site pilot evaluation of several available process options and technologies, including various plate settler designs. Read the full case study to learn how enhanced nutrient removal (ENR) integrated design continues to deliver water quality of <0.1 mg/L Ammonia, <0.07 mg/L Phosphorus and <0.5 NTU. Not only does the WWTP consistently meet EPA direct discharge limits on BOD, Total Nitrogen, Phosphorus and Turbidity, but these final effluent values readily exceed surface water discharge permits levels.

Take Control Of Your Water Distribution Network With Digitalization And Remote Monitoring

Any process plant constantly generates a high volume of status data. Today, this data can be extracted from the plant, stored, analyzed, and prepared to meet operator needs and lower marginal costs.

'TOTEX' Is Key When Purchasing Instrumentation

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.

Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients. By Jeffrey Lane, Steve Skalski, and Gary Engelhart, OI Analytical

Dissolved Oxygen Measurement

One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

TOC Monitoring In Process Return Condensate

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

Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution

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

Sewage Lift Station Pumping System

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

Degradation Of Pharmaceuticals By Advanced Oxidation Process (AOP) In Low Quality Wastewater

Combining Decentralized And Centralized Wastewater Treatment Strategies To Solve Community Challenges

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. 

Managing Storm And Surface Water With ForeSITE UL Monitoring System

As flooding increases along coastal and river-adjacent communities, the need for low-cost, reliable monitoring and warning systems has become a critical factor for managing these issues in real time, without requiring major infrastructure overhauls.
