Maintenance for septic tanks
Septic tanks are widely used for on site sewage treatment for domestic homes which are not connected to the sewer system. Little attention is given to the septic tank until there are problems such as smells or poor drainage or ponding on the surface. A little maintenance of the septic tank can be very helpful in maintaining performance of the septic tank. The outflow from a septic tank percolates ...

Factors affecting the performance and risks to human health of on-site wastewater treatment systems
Aerobic wastewater treatment systems (aerobic systems) are the preferred choice in a region overlying a karstic aquifer used for drinking water supplies, as they are thought to provide better protection to groundwater and human health than standard septic systems. However, aerobic systems in operation do not always perform to design standard; while this is often blamed on lack of maintenance, few ...

Do nonwovens offer a cheaper option?
Untitled Document Could nonwoven filtration material be used as a viable, cheaper alternative to hollow fibre membranes in submerged membrane bioreactors, without a loss in performance? Filtration + Separation takes a look at one research report that thinks so. Nonwoven for the MBR – why bother? The Membrane Bioreactor (MBR) is an evolving process that combines ...

The effectiveness of domestic wastewater treatment technologies in the context of new constraints imposed by lifestyle changes in north american families
Abstract: Family lifestyles have undergone major changes over the last 10 to 20 years. People travels more, eat out more often and. in many families, both parents work outside the home. The growing divorce rate also had an impact 011 home occupancy. The occupancy of a blended family home can also vary from week to week due to shared custody arrangements. Such lifestyle changes all have an impact ...

Kinetics of organic matter and ammonia removal in horizontal reed beds treating wastewater in Nepal
In Nepal, both horizontal bed and vertical bed subsurface flow constructed wetlands have been used for wastewater treatment. However, these units were designed based on the empirical findings from other countries. The rational design criteria developed so far has some limitations as the performance of the units is sensitive to the behaviour of the microorganisms, climatic conditions and other ...

Modeling on-site wastewater treatment system performance fragility to hydroclimate stressors
Increasing variability of climate-related factors, especially precipitation and temperature, poses special risks to on-site wastewater treatment systems (OWTS), which depend on subsurface saturation conditions for treatment and dispersion of wastewater. We assess OWTS fragility – the degree to which a system loses functionality – as a step to characterizing the resilience of residential ...

Rural domestic wastewater treatment in Norway and Poland: experiences, cooperation and concepts on the improvement of constructed wetland technology
This article describes Norwegian and Polish experiences concerning domestic wastewater treatment obtained during nearly 20 years of operation for constructed wetland (CW) systems in rural areas and scattered settlements. The Norwegian CW systems revealed a high performance with respect to the removal of organic matter, biogenic elements and faecal indicator bacteria. The performance of the Polish ...

5 Misconceptions of Why Municipalities Should not Invest In Wastewater Reuse
In the current economic and political climate, municipalities are under immense pressure with regard to water reclamation. Balancing the physical and financial responsibility to provide affordable, clean, and reliable water to its constituents comes at a cost that for most, small to mid-sized municipalities, is hard to justify. However, municipalities have began to acknowledge the growing ...

Domestic wastewater treatment by a constructed wetland system planted with rice
The experiments were conducted in four concrete laboratory scale free water surface constructed wetland units 1 m wide, 1.5 m long and 0.8 m deep. Paddy field soil was added to a depth of 0.4 m and rice seedlings (Oryza sativa L.) were transplanted into the units at a density of 25 plants/m2. Domestic wastewater collected from Chiang Mai University was applied into each unit via two different ...

Intermittent operation of low pressure UF membranes for sewage reuse at household level
A household-scale wastewater treatment system was operated with domestic sewage. The system could recover gardening/irrigation water from raw sewage or secondary effluent by low pressure ultrafiltration (UF). The UF membranes (surface area = 3.5 m2, pore size = 0.04 μm) were operated at constant transmembrane pressure (0.13 bar). The proposed technology was examined for ...

Emerging Contaminants in Municipal Water Treatment: Challenges & Solutions
Ever poured yourself a glass of water and wondered, “What’s really in there?” If you think it’s just H2O, I hate to burst your bubble. We are dealing with more than what’s visible to your naked eye, emerging contaminants in municipal water treatment. It may have once been almost unbelievable, but this is a reality we are facing. It is as real as that glass of water ...

Ideal for onsite chlorine applications
Water treatment could be applied to various fields, our anodes are currently used for Sodium Hypochlorite and Electrolysis of water. Sodium hypochlorite (NaOCl) is a compound that can be effectively used for water purification. It is used on a large scale for surface purification, bleaching, odor removal and water disinfection. It can be also applied in sanitary wastewater and industrial ...

The effect of aeration and effluent recycling on domestic wastewater treatment in a pilot-plant system of duckweed ponds
Three pilot-scale duckweed pond (DP) wastewater treatment systems were designed and operated to examine the effect of aeration and effluent recycling on treatment efficiency. Each system consisted of two DPs in series fed by pre-settled domestic sewage. The first system (duckweed+ conventional treatment) was ‘natural’ and included only duckweed plants. The second system ...

Improving biological phosphorus removal in membrane bioreactors – a pilot study
With increasing water reuse applications and possible stringent regulations of phosphorus content in secondary and tertiary effluent discharge in Florida, USA, alternative technologies beyond conventional treatment processes require implementation to achieve low phosphorus (P) and nitrogen (N) concentrations. A pilot scale membrane bioreactor (MBR) system, operated in Florida, adopted the ...

Municipal wastewater characteristics in Thailand and effects of soft intervention measures in households on pollutant discharge reduction
In developing countries with large Millennium Development Goals (MDGs) sanitation indicator, pollutant discharge reduction function of wastewater treatment systems should be considered. In this paper, pollutant generations per capita (PGCs) and pollutant discharges per capita (PDCs) are estimated as a base dataset for wastewater management in Thailand. PDCs of black water, i.e. toilet wastewater, ...

Comparison of the treatment performance of bio-substrate based and meadow brown soil based subsurface infiltration systems for domestic wastewater treatment
To foster the practical development of subsurface wastewater infiltration (SWI) systems in China, two systems were implemented on the campus of Shenyang University. The bio-substrate filled SWI (BSWI) and meadow brown soil filled SWI (MSWI) system operated under the same operation mode. According to the 12-month experimental results, the bio-substrate had much higher potential to be a good ...
