Benefits Of Ozonation Before Activated Carbon Adsorption For The Removal Of Organic Micro ] Pollutants From Wastewater Effluents

Advanced processes for the removal of organic micropollutants (OMPs) from wastewater 30 effluents include adsorption onto activated carbon, ozonation, or a combination of both processes. The removal of 28 OMPs present in a real wastewater effluent was studied by ozonation coupled  to activated carbon adsorption and compared to a sole adsorption. The influence of the specific ozone dose (0.09-1.29 gO3/gDOC) and the influence of the powdered activated carbon (PAC)  dose (2, 5 and 10 mg/L) were first studied separately. OMPs removal increased with both the specific ozone dose (up to 80% for a dose higher than 0.60 gO3/gDOC) and the PAC dose.  Ozonation performances decreased in presence of suspended solids, which were converted to dissolved organic carbon. A correction of the specific ozone dose according to the suspended solids levels, in addition to nitrite, should be considered.

Water Treatment

The implementation of integrated water and waste management (IWWM) at a mine may, in many instances require the incorporation of a certain degree of water treatment. Water treatment may be required to improve the quality of the water to such an extent that it can be reused by the mine or other users (BPG H3: Water reuse and reclamation). Water treatment may also be required as a final step to render water suitable for discharge in accordance with the conditions of a water use authorisation, catchment management objectives, reserve requirements and/or downstream user requirements.

Best Practices Manual for Small Drinking Water Systems

New regulations pursuant to The Drinking Water Safety Act, administered by the Office of Drinking Water, resulted in changes to the approval, licensing, monitoring, record-keeping and reporting requirements for drinking water systems in Manitoba. It is recognized that many small drinking water systems may not have the same level of access to technical services and resources as larger public water systems. This manual of best practices (a comprehensive, integrated and co-operative approach to continuous improvement of all facets of operations for delivering superior standards of performance) is to assist small drinking water systems with regulatory, management and operational challenges.

Big Data Analysis For Studying Water Supply And Sanitation Coverage In Cities (Russia)

Big data analysis for water supply and sanitation is important for ensuring urban viability. Our research is devoted to studying the methodology for analyzing big data of the water supply and sanitation systems. Based on a review of scientific publications and their analysis, a model for analyzing large data was proposed. It comprises information sources, data collection and storage platforms with indication of parameters for the programming model, runtime and storage environment, as well as data analysis and processing.

Chapter 5 : Biochemical Oxygen Demand (BOD)

In the presence of free oxygen, aerobic bacteria use the organic matter found in wastewater as “food”. The BOD test is an estimate of the “food” available in the sample. The more “food” present in the waste, the more Dissolved Oxygen (DO) will be required. The BOD test measures the strength of the wastewater by measuring the amount of oxygen used by the bacteria as they stabilize the organic matter under controlled conditions of time and temperature.

Biofilm Control Study

Darigold operates a milk products facility in Lynden, Washington. Production processes include evaporation of milk, which generates what is referred to as condensate of whey (COW) water. COW water contains low molecular weight organic compounds including traces of lactic acid, alcohols, acetoin, and non-protein nitrogen (Möslang, 2017). COW water and non-contact cooling water from the Darigold Lynden facility are currently discharged to Outfall 001, which combines with stormwater and the City of Lynden’s wastewater treatment plant (WWTP) effluent discharge to the Nooksack River through the City’s outfall. Darigold’s discharge is regulated under National Pollutant Discharge Elimination System (NPDES) Permit No. WA0002470 administered by the Washington Department of Ecology (Ecology). In the future, Darigold’s COW Water and non-contact cooling water will be directly discharged to the Nooksack River in a new outfall pipe (Outfall 002) currently being constructed by the City.
