To meet the projected population increase from 1,160,000 people currently to an estimated 1,571,000 people in 2031, the Region of Peel decided to upgrade and expand its water treatment plant.

In general, the term blower is a machine used for moving gas with a moderate increase of pressure, but it is easier to answer the question if we compare the fan, blower, and compressor. An air compressor has a high pressure-to-volume ratio, whereas an air blower has a low pressure-to-volume ratio.

The Salisbury Township WWTP in Gap, PA utilized a conventional activated sludge (CAS) system prior to being retrofi tted with an AquaPASS Phased Activated Sludge System in May 2008.

When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.

Learn how common wastewater technologies are being leveraged in decentralized systems and how they can open opportunities for innovation and better water management in the face of drought.

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.

In 2000, the district’s average water demand was 2.3 million gallons per day (MGD) (363 m3/hr) and was estimated to grow over 20% by 2030. Unfortunately, there was not a sufficient or permanent reliable source of supply to meet future demands.

Water storage tanks are critical to communities because they provide clean water to residents and help meet peak demand. Regular inspections and maintenance ensure that everything works as intended so end users have reliable access to water when it is needed.

Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. As they do so, these microorganisms deplete the amount of dissolved oxygen in the water, which can be deadly for aquatic species like fish that rely on dissolved oxygen to live. Because of this hazard to aquatic life, BOD is considered an adverse pollutant in natural waterways where healthy ecosystems are protected. Several states have identified BOD as a pollutant-of-concern related to runoff of stormwater from areas that are associated with industrial activities, and, as a result, have specified water quality limits or objectives for BOD in stormwater discharges from industrial facilities.

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.

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

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.

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.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

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.

Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.

Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.
