The Ivey-sol 1-week pilot application realized significant (81%) LNAPL mass removal. The full scale application achieved regulatory compliance within a few months of application, allowing for the redevelopment of the OU-3 site area. Ivey-sol® was selected over ISCO, Thermal, and Bioremediation based on the results of detailed bench scale ...
It's hard to miss the headlines. The recent outbreak of novel coronavirus disease (COVID-19) has dominated news cycles in recent months. But what information do we have that is related to coronaviruses in water and wastewater systems? And what can water- and wastewater-system operators do to protect public health? Modern water and wastewater treatment systems play an important role in public ...
Client: Heitman Capital Management Completion Date: 2003-present Location: Dallas Services Fixed price remediation Remedial design Bench-scale treatability study Soil remediation (excavation and disposal) Groundwater remediation (chemical oxidation and reactive barrier) Construction-phase services Enhancement of permeability ...
The goal of bioaugmentation is to improve the rate of contaminant removal by adding a high population of beneficial microbes to the contaminated media. The additional microbes should provide short-term benefit as the microbes begin metabolizing the contaminants immediately upon injection. But what benefit does bioaugmentation provide in the long term? And how much benefit does bioaugmentation ...
Soil samples were sent to CL Solutions for bench-scale treatability studies. The following table shows the maximum detected concentrations and the treatment ...
SENTRY technology was deployed as a real-time sensor to control the dosing of free nitrous acid (FNA) in a domestic wastewater treatment stream. The sensor response was evaluated as a solution for optimized dosing of the toxic cleaning agent. Key findings ...
A series of projects will give utilities and others interested in direct potable reuse projects a better insight into the role and use of blending. A study, “Blending Requirements for Water from Direct Potable Reuse Treatment Facilities,” looks at aspects of the practice, albeit on a bench scale. ...
Currently, there is no standard bench-scale dead-end ultrafiltration (UF) testing system. The aim of the present study was to design and build a bench-scale hollow fiber UF system to assess the impact of operational parameters on membrane performance and fouling. A ...
A bench-scale treatability study was completed by an independent laboratory to compare the relative effectiveness of methane and CL-Out cometabolism. ...
Granular activated carbon (GAC) can be used to quench residual hydrogen peroxide (H2O2) after ultraviolet (UV)-H2O2 advanced oxidation processes in drinking water treatment. Bench- and pilot-scale studies examined the possible loss of GAC reactivity due to continuous exposure to natural water from a water treatment plant in both the presence ...
Granular activated carbon (GAC) was used to remove bromide (Br−) and bromate (BrO3−) from drinking water in both bench- and pilot-scale experiments. The present study aims to minimize BrO3− formation and eliminate BrO3− generated during the ozonation of drinking water, particularly in packaged drinking water. Results ...
The average methane yield in litres produced per kilogram of volatile solids fed was 106 for the rigs fed with pasteurised waste and 276 litres for the thermally hydrolysed reactors. A longer more detailed study whereby bench scale mesophilic anaerobic digesters are fed on a daily basis would be required to accurately determine additional ...
The second soil-plant unit was targeted at the removal and recovery of nutrients N, P and K. For the feasibility study, a bench-scale soil column test was carried out, in which red ball earth and alfalfa were utilized for treating synthetic nutrient-enriched wastewater. ...
Nitrogen is one of the elements required for microbial cell growth. Excess nitrate in ground water, however, can be harmful. Denitrification is the process by which select organisms can convert nitrate into nitrogen gas. Bacteria that mediate denitrification, utilize nitrate as a metabolic terminal electron acceptor under anaerobic conditions. While Petrox normally metabolizes organic compounds ...

Co-digestion and pre-treatment have been recognized as effective, low-cost and commercially viable approaches to reduce anaerobic digestion process limitations and improve biogas yields. In our previous batch-scale study, fat, oil, and grease (FOG) was investigated as a suitable potential co-substrate, and thermo-chemical pre-treatment (TCPT) at pH = 10 ...
It is rarely reported that the interaction between xenobiotics and algae may cause potential water quality risks and affect the drinking water treatment process. In the present study, a bench-scale jar test was performed to investigate the effects of the interaction between nitrobenzene (NB) and Microcystis aeruginosa on the performance of ...
As an integral and critical part of this technology offering, we are pleased to offer our bench-scale Treatability Study service for a small fee. Such a study will treat a customer-specific water/wastewater sample – drawn from a customer site – in order to demonstrate the treatability of the specific sample by our AOP ...
Bench-Scale Stormwater Treatment Study A large wire manufacturer in Washington State asked Dungeness Environmental to perform a treatability study on their stormwater run-off. ...
In this study, a broad range of readily deployable metal removal technologies were tested on a US refinery's wastewater to determine vanadium, arsenic and selenium removal performance. The bench-scale treatability studies were designed and performed so that test conditions could be as uniform as possible given the different ...
