Suspended particles in wastewater: their optical, sedimentation and acoustical characterization and modeling
Wastewater regulation and treatment is still a major concern in planetary pollution management. Some pollutants, referred to as particulate matter, consist of very small particles just suspended in the water. Various techniques are used for the suspended particles survey. Few of them are able to provide real-time data. The development of new, real time instruments needs the confrontation with ...

Common Regulatory Practices in Onsite Wastewater Programs: A Willing Suspension of Disbelief
The phrase “a willing suspension of disbelief,” coined by Samuel Taylor Coleridge in his Biographia Literaria published in 1817, refers to the willingness of a person to accept as true the premises of a work of fiction, even if those premises are fantastic or impossible. Prescriptive codes regulating onsite wastewater often carry forward the relics of previous generations even as new ...

Trends in dual water systems
Concerns about aging infrastructure, pressure on water supplies, and increasingly stringent wastewater discharge regulations have led water providers to consider new and innovative approaches. One such approach involves the distribution of reclaimed water through a dual distribution system in which the piping is separated into two separate and independent networks. One network is used ...

Analysis of water pricing in Ireland and recommendations towards a more efficient water sector
Within Ireland, both the public water supply and group water scheme (GWS) sectors are crucial entities in the provision of water supply to individuals. In this study, variances in water charges and operation are assessed via an in-depth survey of 104 GWSs in order to establish the range in both domestic and commercial charges, and also to establish the factors influencing these charges within ...

Bio-Organic Flocculant Treatment for Phosphorus Removal: A Zeoturb - Case Study
Problems with Phosphorus in Wastewater Regulating the discharge of phosphorus from industrial and municipal wastewater treatment plants is a primary factor in averting eutrophication of surface water sources. Phosphorus is one of the key nutrients that contribute to this process in both lakes and natural waters. Its existence has caused major water quality issues such as diminished recreational ...

Viability of
Ascaris and other helminth genera non larval eggs in different conditions of temperature, lime (pH) and humidityHelminth eggs are the pathogens most resistant to inactivation during sludge and wastewater treatment. For this reason, in several regulations and the WHO guidelines for wastewater and excreta reuse for agriculture and aquaculture they are considered as indicators of the performance of the treatment process. Conditions required to inactivate helminth eggs, notably Ascaris lumbricoides, are ...

Combination of extremum-seeking algorithms with effective hydraulic handling of equalization tanks to control anaerobic digesters
The benefits of upgrading extremum-seeking controllers with an effective exploitation of the buffer capacity of equalization tanks have been investigated and applied to anaerobic digesters. In this respect, a Fuzzy-based supervisory module that monitors the state of the equalization tank has been designed and built on top of an extremum-seeking algorithm in charge of automatically regulating the ...

Consortia of microalgae and bacteria in the performance of a stabilization pond system treating landfill leachate
This study treated sanitary landfill leachate and was conducted in a pilot-scale system composed of three serial ponds (P1, P2 and P3), followed by a rock filter, in order to evaluate the microbial consortium influence on system performance and to investigate microorganism dynamics in the process. The system was broken into three stages, with a continuous flow rate (Q = 200 L d−1) ...

An approach to wastewater treatment in organised industrial districts: a pilot-scale example from Turkey
In this study, a detailed wastewater profile and treatability studies of Demirtas Organized Industrial District (OID) were undertaken on a pilot-scale. The industrial categorisation of Demirtas OID was determined, and the wastewater characterisations of each industrial sector were analysed and the flow-rates were measured. The results were used to design a wastewater treatment plant for Demirtas ...
