Nitrogen removal in tertiary wastewater treatment plant of a chemical complex
A Biochemical Contact Oxidation Film (BCOF) technique was piloted for the treatment of a secondary effluent of the Jilin Chemical Industry Corporation (JCIC). The original pulse contact flocculation clarifier used for the tertiary treatment was not performing to the discharge standards. Results show that NH3-N concentration was decreased from 30 mg/L to 15 mg/L, COD concentration was decreased ...

Improving GAC efficiency
PROJECT BACKGROUND: A Superfund Site located in the Northeast US was previously used for reclaiming and re-refining waste oils from 1945-1985. A TSCA inspection uncovered the presence of PCB’s in several lagoons onsite. The site had seven lagoons containing over 9,000,000 gallons of water and oil. Due to heavy rains, the lagoons fill frequently. Therefore, several emergency removal actions were ...

Water treatment case study
Wastewater is any water that has suffered in quality by human intervention. Often, wastewater is being treated for re-use as drinking water or for other purposes. As high levels of nutrition are available in these waters, algae may grow rapidly as well as other micro-organisms such as bacteria. Algae can compete for nutrients against the bacteria in charge of sludge reduction and can also clog ...

Sustainable Industrial Water Treatment Chemicals: A New Era
Ever ponder the progression of a single drop of H2O? Imagine it falling from the sky, rushing through rivers and streams, being drawn into an industrial process, then finally released back to nature. But there’s a crucial step we often overlook – the use of sustainable industrial water treatment chemicals. These silent heroes play an important role in this water journey. The story ...

Online Cu, Zn, As, Se, Cd and Sb Monitoring at an Industrial Smelting Wastewater Treatment Plant
This application focuses on measuring inorganic metals including: copper (Cu), zinc (Zn), arsenic (As), selenium (Se), cadmium (Cd), and antimony (Sb), using Cooper Environmental’s Xact® 920, a continuous multi-metal monitor based-on energy dispersive X-ray fluorescence. Industrial facilities consume and discharge various chemicals as a byproduct of the commodity they produce. The ...

What is Sustainable Flocculation and What are Sustainable Flocculants?
What is Sustainable Flocculation? In most standard drinking water and wastewater treatment systems, there is a flocculation process that is used to reduce the concentrations of solids within the effluent stream. This particular process makes use of substances that aid in the clumping together of suspended particles among other contaminants in a clarifier system. Sustainable flocculation ...

Wastewater Metals Removal
Industrial Wastewater Treatment Success Stories Wastewater Treatment Metals Removal Ton Nerve Gas Agent Container Rinse Waters IE was retained by a United States Army subcontractor to perform a process determination with analytical verification for the treatment of the rinse water from decontaminated nerve gas agents. The Pentagon Munitions Deconstruction Committee (PMDC) fully reviewed ...

Groundwater Remediation Case Study
Wastewater Treatment Success Stories Groundwater Remediation This sample is representative of the ground water that contains diesel fuel from years past. The facility currently uses traditional coagulation/flocculation prior to carbon filters. The objective is to reduce the organic load to the carbon filters to extend life of the carbon filter. The treatment was performed with the addition ...

Fracking wastewater treatment at collection facility
Abstract Engineering company operates a wastewater collection and treatment facility for their clients in Myton, Utah. The facility receives fracking and produced wastewater from various pumping stations, and then treats the water for disposal at the injection well located on site. Electrocoagulation followed by two clarifiers and 5 micron filter was used. Since many particles float or just ...

Aluminum Anodizer Wastewater Treatment Case Study
Manufacturing Wastewater Treatment Case Studies Aluminum Anodizer Case Study 2 The facility treats their wastewater using an EQ Tank followed by a Mix tank and clarifier. The solids that settle are dewatered with a plate and frame press. The treatment process uses caustic to raise the pH from 4 to 9 and then a coagulant along with a metal precipitant as well as a ...

Ultrasound technology in water treatment: Algae control and reduction of biofilm formation
Recent research projects have underlined the potential of ultrasound as a chemical free treatment in water-related applications. This article reviews the use of ultrasound produced by the LG Sonic technology, with a focus on wastewater, irrigation and aquaculture applications. Sound Sound can be described as mechanical energy transmitted by pressure waves in a material medium. Thus, sound ...

What is Zeoturb Bio-Organic Liquid Flocculant Treatment?
In most standard water treatment systems, there is a flocculation process that is used to reduce the concentrations of solids within the effluent stream. This particular process makes use of substances that aid in the clumping together of suspended particles. There are several different substances that have been used for decades, but research continues looking for more. Ideally, newer flocculants ...

Wastewater-Primary Treatment
Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...
