Wastewater treatment plants are required to disinfect effluent prior to discharge in order to destroy any pathogenic organisms present and minimize public health concerns.

Pacific Reef Fisheries (PRF) has been a valued Aeration Industries International (All) client dating back to 2003.

Wastewater flows in seasonal resorts are highly volatile. Learn how to stabilize biological treatment against sudden peak demands and low-flow off-seasons, ensuring continuous compliance and securing a high-quality water source for reuse.

On paper and in practice, aeration options and their corresponding efficiencies are calculated and compared.

Ultraviolet disinfection is now a standard feature in most wastewater treatment systems. UV has also been embraced by the drinking water community as an effective barrier against chlorine tolerant organisms such as Cryptosporidium and Giardia. The technology is widely favored in wastewater treatment due to its non-chemical nature, the fact that no subsequent dechlorination process is required and its ability to be unselective in disinfection performance.

Jar testing is a common laboratory procedure used at water and wastewater treatment plants. In a set of beakers a defined amount of water is mixed with varying amounts of coagulant, and through observation by a trained operator the optimal amount of coagulant can be determined.

Since the name implies that they can be flushed after use, many assume that flushable wipes dissolve completely when flushed. However, it has been recently discovered that not all of these wipes are safe to flush.

Designed to bring practicality and ease to daily, personal sanitary needs, increasingly durable disposable hand wipes have been making a mess with wastewater pump stations. By Smith & Loveless, Inc.

Here are some links and guidelines designed to help utilities change their perspective on water as a low-cost resource of virtually unlimited supply. 

In this white paper, learn how real-time monitoring of ammonia (NH₃) and nitrogen (N) in wastewater treatment plants (WWTPs) can be a game-changer for optimizing treatment performance and energy efficiency.

Selecting the correct accessories will maximize cleaning while minimizing water use, tank refills, labor, and headaches.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

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

The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide.

Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.
