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. 

Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community.

Coking wastewater generated from the processes of coking, coke gas purification, and recovery of coking products, is highly toxic and carcinogenic. The wastewater usually contains phenolic, aromatic, heterocyclic, and polycyclic organics, and some inorganics, such as cyanides, sulfides, ammonium, ammonia, and so on, which makes it hardly degradable.

Sherbourne Common is an innovative waterfront park that provides the public with green recreational space along Lake Ontario in a former industrial area. 

Wastewater treatment plants provide a viable option to accept and process the collected septage. However, the sheer concentration of the transported sludge can potentially cause plant upsets in smaller WWTP facilities.

The district manager for the Pinetop-Lakeside Sanitary District (AZ) reports that a special gas chlorination system, featuring unique components and controls, and manufacturer-supplied service, has effectively replaced a chlorine tablet system.

Natura Solve provides a complex liquid medium that is produced via a proprietary fermentation process. It consists of a selected spectrum of naturally occurring microorganisms, sustained within a matrix of micro elements and macro elements that provide the critical building blocks for respiration and growth. Thus it simultaneously works as both a biocatalyst, stimulating endogenous bacteria metabolic and production rate and a specialized delivery medium for the highly effective bacteria. The formula is very aggressive due to the essential balance between the selected groups of microorganisms, which, when combined with the enzymes they produce, synergistically create catalyzing proteins that significantly speed up the biochemical reactions and natural decomposition processes of the organic material into humic matter.

The Moab Water Reclamation Facility (WRF) was initially constructed in the late 1950’s to provide primary treatment of domestic wastewater for the Moab area. However, the plant could no longer keep up with the higher flows and loading due to population growth and rising tourism. In addition, with aging infrastructure and the new permit cycle in sight, upgrades to the biological treatment were necessary to ensure full compliance. Read the full case study to learn more.

Olayan Voltas Contracting Company was awarded the 2013 “Sustainable GCC Project-of-the-Year” by MEP Middle East magazine for the utility complex at Al Bustan Village, a brand new residential community north of Riyadh, Saudi Arabia.

A stormwater management system designed for a new convenience store in Sarasota, FL, required a sophisticated and elaborate approach. When it was completed earlier this year, the complex system resulted in huge money and time savings for the property owner, which will enable the store to open this fall.

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.

Learn how a wastewater treatment plant in eastern Switzerland relies on the targeted use of flocculants to prevent sludge washout. 

In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

Learn about filtering microplastics from industrial wastewater prior to discharge, and how this is one way to effectively reduce the volume of this waste material from entering our surface water.

Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

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

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.

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.
