Application of water pollution detector
Background: The (nitrate) link between agriculture and water quality is nutrient abundance - I've always thought the main issue was with fertilizers. Excessive nutrient loss often leads to eutrophication of surface waters. This condition can lead to harmful algal blooms (HAB), which produce dangerous toxins and cause a drop in dissolved oxygen, killing fish in both marine and freshwater ...

Case Study: WTP Optimizes Well Blending with Online Nitrate Analyzer
The Village of Port Williams is a thriving agricultural community in Nova Scotia, Canada. Like many agricultural communities, long-term fertilizer application to the land has led to elevated levels of nitrate in groundwater. Nevertheless, the local water supply plant continuously produces high quality drinking water. With a reliable nitrate monitoring system from Real Tech and a solid management ...

Introducing the OTT ecoN
New generation of UV Nitrate Sensors Nutrient monitoring is becoming more important as time goes on – as human activity increases the natural amount of nitrate in water, plants and organisms are more and more negatively affected. Current nutrient monitoring relies on low temporal frequency monitoring and spot-checking, which are vulnerable to uncertainties and less representative of the ...

Understanding the contribution of biofilm in an integrated fixed-film-activated sludge system (IFAS) designed for nitrogen removal
The objective of this study is to improve knowledge on the integrated fixed-film-activated sludge (IFAS) system designed for nitrogen removal. Biofilm growth and its contribution to nitrification were monitored under various operating conditions in a semi-industrial pilot-scale plant. Nitrification rates were observed in biofilms developed on free-floating media and in activated sludge operated ...

Baseflow contribution to nitrates in an urban stream in Daejeon, Korea
It is a well-known fact that baseflow discharge of rainfall runoff significantly impacts the quality of surface water. In this paper, the impact of nitrates discharged as baseflow on stream water quality were studied using PULSE, a hydrograph separation software developed by USGS, to calculate the monthly baseflow discharge. We took water quality and flow rate data from a monitoring station site ...

Wastewater Plant Stays in Control with Nutrient Analysis System
Overview Denver uses ChemScan analyzers to monitor its centrate and RAS reaeration basin (CaRRB) process, ensuring nitrate and ammonia are reduced before mainstream aeration. Challenge The Denver Metro Wastewater Reclamation District wanted near real-time nutrient analysis for a very challenging headworks wastewater aeration process. This process consists of a combination of centrate and ...

Nutrient analysis system keeps wastewater plant in control - Case Study
Problem The Denver, Colo., Metro Wastewater Reclamation District wanted near real-time nutrient analysis for a very challenging headworks wastewater aeration process, consisting of a combination of centrate and RAS. The centrate and RAS reaeration basin (CaRRB) effluent is added to primary effluent prior to mainstream aeration. Solution ASA Analytics supplied a centralized nutrient analysis ...

Photodegradation of 4-chloronitrobenzene in the presence of aqueous titania suspensions in different gas atmospheres
The photocatalytic degradation of 4-chloronitrobenzene (4-CNB) was carried out using Degussa P25 TiO2 as photocatalyst in three different gas atmospheres: nitrogen, oxygen, and ozone. The total organic carbon (TOC) and inorganic anions including chloride, nitrite, and nitrate anions were measured to monitor the mineralization processes, while the degradation of 4-CNB and the formation of ...

Application of multivariate methods in the monitoring of marine environment: simultaneous determination of bromide, bicarbonate, nitrate and sulphide in seawater by ultraviolet spectroscopy
In this paper we present a new ultraviolet (UV) spectroscopic method for the simultaneous and reagentless determination of bromide, bicarbonate, nitrate and sulphide ions in artificial seawater solutions, applicable to the monitoring of the marine environment. We collected the UV spectra of artificial seawater samples with salinity between 8 and 45 psu, having known concentrations of these ...

A sewer process model as planning and management tool – hydrogen sulfide simulation at catchment scale
The collection system of a major city at the Persian Gulf was simulated for bulk water hydrogen sulfide and the release of sewer gas to the urban atmosphere. Geometry data on 870 km of sanitary sewer and data on dry weather flow entering all nodes in the catchment was exported from a Mike Urban database and imported to the sewer process model WATS. The process model then routed sewage and sewer ...

Tech-IA floating system introduced in urban wastewater treatment plants in the Veneto region – Italy
The performance of three integrated wetland treatment plants (horizontal sub-surface flow (h-SSF) and floating treatment wetland (FTW) with differentiated primary treatments) designed for treating domestic wastewater was investigated, monitoring total (TN), nitrate (NO3-N), nitrite (NO2-N) and ammonia nitrogen (NH4-N), total (TP) and phosphate phosphorus (PO4-P), chemical (COD) and biological ...

Economic value of biosolids in a semiarid agroecosystem
Over half of the municipal biosolids generated in the United States are being applied to agricultural land. More information is needed on crop response to biosolids application and on the optimal level of the application from an economic prospective. With this in mind, data from two sites used in a long-term biosolids application study of an Eastern Colorado wheat (Triticum aestivum L.)–fallow ...
