Addressing Sewage Pollution in the UK
News of excessive sewage spills comes as government plans overhaul of system Wastewater treatment facilities in the United Kingdom are facing pressure after recently revealed data showed an average of 1,000 sewage spills per day were detected there in 2021. Data from England and Wales has shown that sewage systems released raw sewage into the environment 372,533 times last year, with an ...

Supercritical water oxidation of sewage sludge – state of the art
Supercritical water oxidation (SCWO) is an innovative and effective destruction method for organic wastewater and sludge. Several tests of the destruction of sewage sludge by SCWO have been done at two state of the art pilot plants. These units have capacities of 250 kg/h and 1100 kg/h, respectively. The test results show that the technology easily destroys the organic material in the sludge and ...

ISO14001 Environmental Aspect Illustrated
An Industrial Effluent Treatment System (IETS) and Sewage Treatment System are delicate biotechnical equipment. Their biochemical dynamics often varies not according to mechanical equations that we prompt them to. Occasionally we encounter systems upset and expensive rectification work. Bulking, foaming and other symptom of ‘shock-loading’ are common challenges in IETS operation. ...

Source identification of fecal contamination in the canals in Bangkok using fecal sterol compounds
This study aims to apply fecal sterols as a chemical indicator to track feces contamination sources in the canals in Bangkok. The sewage and canal sediments were examined during the dry season. Fecal sterols in the canals were evaluated over a one-year period (2011–2012) for the selected sterol compounds. Several factors including season, canal water levels, rainfall data, and sewage were ...

Aerobic wastewater treatment processes history and development synopsis
This book is an overview of the development of aerobic waste water treatment and influences which shaped this development. The historical development of sewage treatment and the subsequent emergence of aerobic biological treatment methods is investigated from the early nineteenth century to the present day. In addition, the earlier historical background, up to the late ...

Near-infrared spectroscopic assessment of contamination level of sewage
We examined the use of near infrared (NIR) spectroscopy as a rapid technique for the evaluation of sewage quality. Influent water samples, primary sedimentation tank water samples, and final effluent water samples were collected from sewage treatment facilities in Nagoya, Japan and their NIR spectra obtained. Partial least squares (PLS) models for total phosphate (TP), total nitrogen (TN), ...

Dibba Al – HISN Sewage Treatment Plant – Sharjah case study
Introduction Corodex Industries was awarded a Sewage Treatment Plant (STP) project with the capacity of 10,000m3/d by Sharjah Municipality for Dibba Al-Hisn. The STP is built using the latest technology in sewage treatment known as Membrane Bioreactor (MBR). MBR treats sewage to a level that effluent can be discharged to marine life or can be used for restricted irrigation The STP supplied by ...

Influences of rainfall variables and antecedent discharge on urban effluent concentrations and loads in wet weather
For storm drainages inappropriately connected with sewage, wet weather discharge is a major factor that adversely affects receiving waters. A study of the wet weather influences of rainfall-discharge variables on storm drainages connected with sewage was conducted in the downtown Shanghai area (374 ha). Two indicators, event mean concentration (EMC) and event pollutant load per unit area ...

Characteristics and potential uses of sewage sludge in the commercial capital of Bangladesh
Based on contrasting properties, sewage sludge can be co-recycled in order to take simultaneously the best profit and minimise environmental pollution. The present study was conducted to assess the physical and chemical properties of sewage sludge generated from different sources in the commercial capital of Bangladesh and on the basis of these characteristics a variety of ways had been fixed to ...

Solar disinfection and lime stabilization processes for reduction of pathogenic bacteria in sewage effluents and biosolids for agricultural purposes in Yemen
Yemen is the least advanced country among Middle Eastern countries in sewage reuse and safety control. The current sewage effluent quality in Yemen is generally poor as none of the existing sewage treatment plants produces effluents that comply with the effluent quality regulations. There is no plan to build tertiary treatment systems. However, the oxidation and stabilization ponds are ...

KSFA Info-FLO: “Better than New Septic from Bio-Microbics!“
Better than New Septic from Bio-Microbics! In Western Kansas, those properties that experience biologically-failed septic systems rarely have options other than to replace the entire system - an expensive endeavor for low-income housing. For a family located in Finney County, the local authorities identified the tell tale signs of a biological failure from their 20-year-old septic system. ...

Sewage Sludge Recycling to Land and Disposal
The Problem: Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent). A by-product of sewage treatment is usually a semi-solid waste or slurry, called sewage sludge, that has to undergo ...

Transitioning to sustainable sanitation through transdisciplinary inquiry - A case study of trialling urine diversion in urban Sydney, Australia.
Availability of phosphorus underpins global food security and, with rapidly declining resources of mineral phosphate deposits, there is a critical need to identify alternative sources of phosphorus for global food production. Urine is a potential source of phosphorus, yet to capture, value, and reuse urine requires a transformation in how we think about sewage in multiple dimensions - the ...

Solar Drying of Sewage Sludge
Abstract Any Sewage Water Work throughout the world will produce sludge, a form of biomass growing in the basins. This biomass has to be evacuated and is, generally speaking difficult to handle! When liquid it has a dry matter of 3 to 4 %, or only 30 to 40 kg per ton of sludge, when mechanically dehydrated to 20 - 25 % most of it is still water, as an average 750 to 800 kg per ton of filter ...

Overview of legislation on sewage sludge management in developed countries worldwide
The need to apply innovative technologies for maximizing the efficiency and minimizing the carbon footprint of sewage treatment plants has upgraded sewage sludge management to a highly sophisticated research and development sector. Sewage sludge cannot be regarded solely as ‘waste’; it is a renewable resource for energy and material recovery. From this perspective, legislation on sewage ...

Operational decision support system for large combined sewage systems: Lisbon/Tagus estuary case study
Managing combined sewage systems in large cities discharging to coastal waters, often bearing recreational activities, remains a challenge. Studying the impacts of such discharges requires the development of specific models. Hydrodynamic and water quality modelling of coastal waters employs numerical methods and algorithms, leading to the design of complex models which require expert use. The ...
