High performance of nitrogen and phosphorus removal in an electrolysis-integrated biofilter
A novel electrolysis-integrated biofilter system was developed in this study to evaluate the intensified removal of nitrogen and phosphorus from contaminated water. Two laboratory-scale biofilter systems were established, one with electrolysis (E-BF) and one without electrolysis (BF) as control. The dynamics of intensified nitrogen and phosphorus removal and the changes of inflow and outflow ...

Wetland Biofilter System provides year-round, cost effective treatment to over 1.5 million litres of wastewater
The success of early surface flow treatment wetlands in Canada was limited by hydraulic blockages and oxygen limitation due to freezing. From 1991 to 1996, Dr. Edgar Lemon, with the Friends of Fort George, researched a sub-surface vertical flow constructed wetland treating lagoon effluent at Niagara-on-the-Lake, funded by the Ontario Ministry of Environment (MOE) and the United States ...

Subsurface Bio Filter Cell System - Case Study
These benefits are perfectly matched for this project: construction of a subsurface biofilter cell system for the removal of selenium and nitrate. To meet this EPA requirement, the Irvine Ranch Water District (IRWD) developed a plan to address regional water quality treatment. The plan included the Cienega Filtration Facility adjacent to the Peters Canyon Channel that is specifically for removing ...

Mesquite wood chips (Prosopis) as filter media in a biofilter system for municipal wastewater treatment
The biofiltration system over organic bed (BFOB) uses organic filter material (OFM) to treat municipal wastewater (MWW). This study evaluated the performance of a BFOB system employing mesquite wood chips (Prosopis) as OFM. It also evaluated the effect of hydraulic loading rates (HLRs) in order to achieve the operational parameters required to remove organic matter, suspended material, and ...

Performance of a biofilter system with agave fiber filter media for municipal wastewater treatment
Agave plants grow in semi-arid regions and are used for mescal production. However, agave fiber by-products are considered waste materials. Thus, we tested agave fiber as a filter media and biofilm material carrier for removing pollutants from municipal wastewater. Three laboratory-scale biofiltration reactors were used in two trials with five hydraulic loading rates (HLRs = 0.27, 0.54, ...

High Rate Biological Odour Control System - Case Study
About the Project Biorem has conducted a successful demonstration of high rate odour control at Preston Wastewater Treatment Plant in Cambridge, Ontario over the last three years. The system treats exhausts from primary clarifier and intermediate pump station. A combination of biotrickling filtration (BTF) and biofiltration (BF) processes was used in a novel horizontal flow configuration. XLD, a ...

Summer Camp Experience - The Minnesota onsite association installs technology to bring wastewater treatment at a Girl Scout camp into the 21st century
After several weeks of preparation by James Brothers Construction, six advanced treatment systems were installed on June 22 and 23 at the Singing Hills Girl Scout Camp near Elysian, Minn., during the Minnesota Onsite Wastewater Association (MOWA) 2007 summer seminar. The event was an opportunity for onsite professionals to get hands-on training and experience installing new technologies while ...

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 ...

Sustainable, Low-maintenance Disinfection for Onsite Systems
Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...

JWPCP Carson - Case Study
The Los Angeles County Sanitation District operates 11 wastewater treatment plants treating approximately 576 MGD for the massive population of the greater metropolitan LA County area. Six of the largest facilities the District operates are connected through a regional network of sewers and treatment facilities known as the Joint Outfall System (JOS), serving the water treatment needs of roughly ...

Evaluation of the absorption bed`s efficiency under the Ecoflo Biofilter
The Ecoflo Biofilter is a wastewater treatment system designed for the sanitary drainage of decentralized dwellings. Preceded by a scptic tank, the chain of treatment comprises a biofiltration unit and a polishing field allowing the treated wastewater to be absorbed by the rcceptor ground. The Ecoflo Biofilter performances have been evaluated by numerous organizations (MDDEP, BNQ, NSF, CSTB, ...

Laboratory study on factors influencing nitrogen removal in marble chip biofilters incorporating nitritation and anammox
It remains challenging to integrate nitritation and anammox in ecologically engineered treatment systems such as passive biofilters that are packed with natural materials and have low energy inputs. This study explored the factors influencing nitritation-anammox through parallel operation of two laboratory-scale biofilters packed with large and small marble chips respectively. Clean marble chips ...

Biological Filtration: Future of Drinking Water Treatment
Water is essential for all human life on the planet, but the fresh water supply is limited and is susceptible to being contaminated by all manner of toxins like arsenic, calcium, and mercury. There are many techniques to remove contaminants, including popular methods that add chemicals to balance others out, but one that not many people understand is biological water system filtration. Biological ...
