  • Small domestic wastewater treatment using waste materials

    Phosphorus pollution of groundwater from small wastewater system is often considered as a major threat for aquatic habitats. Recirculating biofilters are often used to treat small wastewater systems without significant removal of phosphorus. In this paper, a low-cost waste material (dried alum residual) in pre-treated effluents from recirculating biofilters was examined. Two different types of ...

  • SBR Wastewater Treatment Provides Large Clean-up on Small Site

    One of the largest capacity wastewater treatment plants in Europe is under construction on a small plot of land at Ringsend, on Dublin Bay in Ireland. Sequencing batch reactor (SBR) technology and 100,000 diffusers from ITT Industries' Sanitarie unit was selected to meet the challenging waste treatment needs for this site. When Dublin's wastewater treatment plant was built in the 1970s, it ...


  • Lagoon treatment and disposal retrofit at a small community wastewater facility

    Kendal~Crosslands Communities has managed its wastewater since the early 1970s by use of a lagoon treatment and spray irrigation disposal facility. The facility is the first in Chester County, Pennsylvania, to utilize the environmentally friendly spray irrigation method for disposal of treated wastewater. Spray irrigation has become a preferred method of land application disposal and a valuable ...

  • Small-bioreactor platform technology as a municipal wastewater additive treatment

    The bioaugmentation treatment approach presents both an economical and environmentally friendly solution for wastewater treatment. However, the use of exogenous bacterial cultures presents several limitations: negative interaction between microorganisms and adaptation to new physical and chemical composite environment. These selective forces create a significant challenge for the introduced ...

  • Design configurations for commercial application of biomass carriers in small wastewater treatment plants

    Introduction Moving bed type reactors are bio-film processes utilizing small, plastic biomass carriers that mix in the water. The use of biomass carriers is becoming common world-wide, for many applications, some of which are: compact low operation units, industrial wastewater roughing filters, retrofit and upgrade of municipal wastewater treatment plants. The AGARTM Process (Attached Growth ...

  • Inetgrated Planning for Wastewater Treatment and Recycling for a Small Community Development

    ABSTRACTIntegrated water resources planning was conducted for Olowalu Town, a proposed development in western Maui, Hawaii. Total water needs, which can be supplied by a combination of diverted surface water, well water, recycled water and captured stormwater, are estimated at between 1 and 2 mgd. The Olowalu development will generate approximately 0.5 million gallons per day (mgd) of municipal ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...

  • Viltra IWOX systems engineered by DMT - The next standard in small scale wastewater treatment

    Abstract Both technology and environmental awareness drive legislation for wastewater treatment. Now, the leap from 20/30 (BOD: Biological oxygen demand, mg/l / SS: suspended solids, mg/l) to 10/10 or even 5/5 is possible due to a different design approach. For years, the sewage treatment plant market was dominated by systems from (septic) tank suppliers, but now an engineering company ...
