All of our work here at Aquafix is guided by our mission statement: “Safer water and better lives through pioneering biosciences.” In line with this mission, we have conducted and are continuing to conduct numerous studies involving quaternary ammonium cations (QACs or quats) and their toxicity concerning wastewater microorganisms, in both aerobic and anaerobic processes. Past studies ...
The project started in August 2001 with the introduction of four-2HP WTR Fine Bubble Diffusion surface aerators in combination with the blower system until November 2001. As a test, from November to present all four units were utilized as the only source of aeration in the 1ST cell. These units were located in the South East corner of the lagoon, near the influent. During this ...
In fact, you may even recognize the genus name of water fleas, daphnia, as they are used in effluent WET testing. Water mites, on the other hand, are not as likely to be recognized by their scientific name, Hydrachnidia, because there are over 6,000 known species and they only occasionally appear in wastewater plants. ...
Axine Solution Benefits Eliminates bottlenecks associated with off-site trucking & disposal Provides the site with operational flexibility to accommodate future expansion Onsite service model reduces opex costs vs. offsite incineration Eliminates 20,000 miles/yr of trucking & 1.7 million Ibs/yr of waste Test Methodology Before entering into a service ...
Salt levels are measured in terms of milligrams per liter (mg/l), which is identical to parts per million (ppm). The higher the test value, the higher the salt content of the effluent water. Salt levels are also expressed in terms of total dissolved solids (deci–siemens per meter [dS/m] or millimhos per centimeter [mmhos/cm). Listed below is the general ...
In this study, we assessed the impacts of Qwik-Zyme P on poultry protein hydrolysis using oxygen uptake tests on samples collected from an anaerobic lagoon effluent, which enters into an aeration basin. An increase in oxygen uptake rate indicates improved aerobic degradation rates of the anaerobic effluent wastewater. As anaerobic systems tend to ...
In this TKI project (Topconsortia for Knowledge and Innovation), the removal of medicines and their residues from wastewater treatment plant effluent was examined on a laboratory and pilot scale. Research Type | Medicine Removal from WWTP effluent through advanced oxidation (AOP) Research project| TKI project in cooperation with KWR Year | 2016 Medicines are ...

Optimal dose rates properly determined and set at the start of the treatment and verified with adequate frequency, pH control to maintain pH in the optimal range for coagulation by chitosan, well maintained sump, regular equipment maintenance (flow switch check, chemical injection lines, filter maintenance, etc.) are all important steps to ensure safe and effective use of chitosan. Residual ...
Abstract : A battery of Toxkit microbiotests with 4 aquatic species from different trophic levels has been used to evaluate the toxicity of 2 types of point source pollution in the Voivoidship of Opole in Poland : percolating waters from drainage systems of 4 municipal waste dumps and the effluents of a sugar factory. In addition, the toxicity of groundwaters from 2 wells near 2 ...
Abstract : In recent years there has been increasing development of methods (particularly rapid tests) for testing environmental samples. If appropriate methods are to be used for a particular operational role then it is necessary to adopt a robust and objective selection mechanism. This paper describes the application of a criteria-based procedure to the ...
Abstract :The Resource Management Act 1991, of New Zealand, requires local authorities and industry to apply for consent to discharge effluent to water or land. The requirement for whole effluent toxicity testing is now being included in these Resource Consents. ...
“We spent much of that month testing various samples to compare its accuracy to EPA Method 1664B.” The first sample tested was a 40 ppm standard. ...
Yearlong test of revolutionary wastewater treatment certifies MABR’s compliance with Title 22 nonpotable reuse After a yearlong pilot test of Fluence’s membrane aerated biolfilm reactor (MABR) wastewater treatment technology at Stanford University’s Codiga Resource Recovery Center (CR2C), the CRC2 team has published interim results declaring it ...

Crotamiton, a scabicide and antipruritic agent persistent during biological treatment processes, is frequently detected in secondary effluent. In this study, titanium dioxide (TiO2) and high-silica zeolite (HSZ-385) composites were synthesized and applied for the treatment of crotamiton in secondary effluent. Crotamiton was rapidly adsorbed by HSZ-385, and ...
Over time as production on site has increased, so too has effluent volumes and contamination levels. Although rarely breaching discharge consent limits, the management team at Avondale Food were conscious that the quality of effluent being discharged to sewer was compliant, but not as good as it once was, leading to increased effluent discharge ...
It has hence served as a 125 PE plant. Effluent tests have been made 12 times annually and the plant has so far not experienced any problems or technical ...
This work evaluated the performance of a dissolved air flotation (DAF) system for biomass recovery from the effluent of algal ponds used for sewage treatment in Northeast Brazil. Two different coagulants and effluent samples were tested following a random-factor experimental design (34–1–4 factors and 3 levels), in triplicate. ...
The study was executed at Kalurghat industrial area to determine the efficiency of effluent treatment plants by testing different physicochemical parameters. Results revealed that only 3 out of 9 industries treated their effluents efficiently and discharged following the standards of Department of Environment. The remaining industries viz. ...
We identified six commercially available silver test strips, kits, and meters, and evaluated them by: (1) measuring in quintuplicate six samples from 100 to 1,000 mg/L (application range) and six samples from 0.0 to 1.0 mg/L (effluent range) of silver nanoparticles and silver nitrate to determine accuracy and precision; (2) conducting volunteer ...
