  • Performance of a constructed wetland for treating farm-yard dirty water

    Constructed wetlands (CWs) have been used to treat agricultural effluents with varying success especially with respect to their operational efficiency in winter and ability to retain phosphorus. Dirty water (DW) from dairy farms is a mixture of manure contaminated runoff and milk parlour washings with a highly polluting biochemical oxygen demand (BOD) ≤3,000 mg/L. The initial performance a CW of ...

  • Factors affecting the performance of a single-chamber microbial fuel cell-type biological oxygen demand sensor

    Microbial fuel cells (MFCs) are devices that exploit microorganisms as biocatalysts to degrade organic matter or sludge present in wastewater (WW), and thereby generate electricity. We developed a simple, low-cost single-chamber microbial fuel cell (SCMFC)-type biochemical oxygen demand (BOD) sensor using carbon felt (anode) and activated sludge, and demonstrated its feasibility in the ...

  • New dimensiong guideline and standard for the activated sludge process

    Since June 2016 a new standard for the design of activated sludge systems is valid. The most significant point is the change of the basic value from BOD to COD. The standard is also the basis for designing SBR-systems. The article discusses main aspects of the new design basis and how AQUA DESIGNER has been modified and adapted to this. In AQUA DESIGNER you can calculate the continuous and ...

  • UASB-CFID system: energy efficient technology for sewage treatment and reuse

    The UASB-CFID system was investigated through laboratory experiments as an alternative method of treatment to existing UASB based STPs for the treatment. Excellent quality effluent was obtained having BOD and TSS below the disposal standards of India. In conventional treatment methods, lot of energy is wasted and also they generate harmful byproducts. The estimated life cycle cost of UASB-CFID ...

  • Lowes Plaza commercial wastewater system information

    Commercial wastewater is usually highly concentrated in organic content and complicated by sanitary routines and house keeping habits that shorten the expected life of the soil disposal system.  Advanced wastewater treatment will preserve the disposal system indefinitely and often represents a one to three year return on investment for commercial facilities. This Aquapoint wastewater ...

  • Marine Sciences Investigations in Support of Level Oftreatment Decisions for Municipal Wastewater Discharges in Puerto Rico

    ABSTRACT The Puerto Rico Aqueduct and Sewer Authority (PRASA) currently has National Pollutant Discharge Elimination System (NPDES) permits that incorporate relaxation (waiver) of BOD and TSS secondary treatment requirements for six of its regional wastewater treatment plants. The waivers are available under Section 301(h) of the Clean Water Act. Maintaining the waivers requires, in part, ...

  • Measuring Short-Term BOD

    Measurement of oxygen uptake rates in activated sludge processes is essential to their satisfactory operation. Traditionally, oxygen uptake rates (OUR) have been determined by using a dissolved oxygen probe to measure the change in dissolved oxygen in a BOD bottle. While this method is rapid, it provides only a snapshot, at a single point in time, of the oxygen uptake rate reaction in a treatment ...

  • Feasibility of UASB/trickling filter systems without final clarifiers for the treatment of domestic wastewater in small communities in Brazil

    The paper analyses the concept and performance of different configurations of compact UASB/TF systems, without the final clarification stage, in relation to the removal of organic matter. The experiments were carried out in two sets of UASB/TF systems operating without secondary clarifiers, as follows: (i) four shallow (2.50 m height) TFs, each one filled with a different packing material; and ...

  • Applicability of MIKE 21 to assess temporal and spatial variation in water quality of an estuary under the impact of effluent from an industrial estate

    This study aims at analysing the impact of wastewater load of industrial units in Haldia on the water quality of the Hoogly estuary using numerical modelling techniques. Modelling was never attempted in this region because it was generally felt that simulating such a complex system would not be easy with limited data availability but MIKE 21, a hydrodynamic and water quality model, was used to ...

  • Monitoring outfalls to Bathing Waters - Case study

    Bathing Water Catchment monitoring Date:2010 Location: Bude Cornwall UK Purpose: To carry out a river survey identifying potential pollution sources and their likely impact on bathing waters downstream. Background STS and the Environment Agency have, for some time, been discussing the issue of monitoring water courses which discharge directly into bathing waters. Of ...

  • Risk analysis of seasonal stream water quality management

    Seasonal discharge programs, which take advantage of temporal variation of stream assimilative capacity, are cost effective. However, these seasonal discharge control programs should not increase the risk of water quality violations. A method is presented to estimate the allowable pollutant loads under both seasonal and non-seasonal discharge control programs for a single discharger that ...

  • The application of surface engineered silica for the treatment of sugar containing wastewater

    The removal of sucrose and fructose from water at various high concentrations by surface engineered silica (SES) was studied using dissolved sugar in pure water. The results indicate that sugar at concentrations of up to 800 g/L can be removed by SES at a relatively high dose of 250 to 300 g/L. Based on these results, process water from a soft drink filling station which was contaminated by ...

  • Southwest landfill case study

    The Problem: A landfill located in Texas was experiencing high concentrations of ammonia in the leachate from their domestic landfill. Compliance standards were becoming more stringent at the same time ammonia and BOD levels in the leachate stream were increasing in concentration. The Solution: After on‐site testing ...

  • Water quality assessment of Malad Creek, Mumbai, India: an impact of sewage and tidal water

    The aim of the study was to carry out water quality assessment and to identify sources responsible for deterioration of quality in the Malad creek, Mumbai, India. Creek receives sewage and wastewater from various drains and partially treated effluent from Malad and Versova treatment facilities. To assess the water quality, sampling locations were identified in the creek based on discharges of ...

  • Mixing To Enhance Facultative Wastewater Lagoon Treatment

    SolarBee® & GridBee® Are Leading The Way In most lagoons, sunlight causes a hard stratification at 12 to 18 inches of depth.  The top water is warmer and thick algae populations are producing supersaturated dissolved oxygen (DO).  The DO gasses off at the surface and is not readily available deeper in the pond for use by BOD-reducing bacteria. Meanwhile new ...
