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 ...

Small-Scale Wastewater Treatment Systems for 3 Markets: USAID Philippine Sanitation Alliance Projects in the Philippines
Lack of access to improved sanitation and lack of sanitation treatment infrastructure is a major issue facing the Philippines and other Southeast Asian countries. 2008 data estimated that 24% of the Philippine population still did not have access to personal improved sanitation, 15% of which rely on shared sanitary facilities and 9% of which rely on open defecation or the use of unimproved ...

Harlem, MT USA WWTP Uses FLUMP - 2013-case study
Excessive lagoon sludge accumulation contributes to the poor performance of any treatment system. Removing sludge from lagoon cells improves treatment and addresses violations in the Department of Environmental Quality enforcement action. The City of Harlem, Montana has a three cell partially mixed aerated lagoon system constructed in 1985. The lagoon system discharges to the Milk River. ...

Training: How to Remove Lagoon Sludge and Improve WWTP Outcomes
What should you do when your town is under multiple and ongoing consent orders for violations of its Montana Pollutant Discharge Elimination System (MPDES) wastewater discharge permit? Excessive lagoon sludge accumulation contributes to the poor performance of any treatment system, particularly in winter. Removing sludge from the lagoon cells will improve treatment at the facility and help to ...

Environmental assessment of two small scale wastewater treatment systems: SBR vs CAS
European Water Directive 91/271/EEC introduced a series of measures aimed at protecting sensitive areas against the emission of nutrients originating from waste water treatment plants. There are, however, environmental costs associated with achieving the required level of water quality, such as greenhouse gas emissions resulting from energy consumption. The goal of this study is to assess ...

Study of aggregation in surface sludge deposits from 14 full-scale French constructed wetlands using particle size distribution and dynamic vapor sorption analyses
French vertical flow constructed wetlands (French VFCWs) are widely used for the treatment of wastewaters from small communities. In the system, unsettled wastewater is percolated through two successive stages of filter-cells planted with reeds. This causes the formation of a surface sludge layer. This layer plays positive roles in the treatment performance, but also leads to clogging. The ...

SISAR: a sustainable management model for small rural decentralized water and wastewater systems in developing countries
Investments for basic rural sanitation programs should not only focus on the construction of new installations, but also on the necessity of implementing proper management models that guarantee the operational and financial sustainability of the investments. The integrated rural sanitation system (SISAR) is based on the idea of creating a confederation of local user groups which come together ...

American Jobs Plan Presents Opportunities for Decentralized Water Treatment
The plan changes how we think about the basics by emphasizing infrastructure renewal On March 31, the White House announced its American Jobs Plan (AJP), which it said would “invest in America in a way we have not invested since we built the interstate highways and won the Space Race.” President Joe Biden said, “It’s not a plan that tinkers around the edges.” The ...

Analysis of constructed wetland performance for irrigation reuse
Most of the wastewater treatment systems in small rural communities of the Cova da Beira region (Portugal) consist of constructed wetlands (CW) with horizontal subsurface flow (HSSF). It is believed that those systems allow the compliance of discharge standards as well as the production of final effluents with suitability for reuse. Results obtained in a nine-month campaign in an HSSF bed pointed ...

Wastewater treatment plant operators work confidently with complete system measurement
Wastewater treatment is a vitally important process. Just ask The Township of Edwardsburgh/Cardinal’s Assistant Chief Water and Sewer Operator, Eric Wemerman. “For a community to keep everyone’s trust you want to make sure you’re operating a good system.” Eric continues. “It’s important for health reasons, when people flush their toilets you need to get ...

Pulsar Measurement Provides End-to-End Solutions for Wastewater Treatment Plant
The Township of Edwardsburgh in Eastern Ontario, Canada operates a wastewater treatment system for a small community of about 6,900 people. One of the main challenges for this system is that all the working parts of the process are all spread-out. Pulsar Measurement provided the township with a variety of ultrasonic flow and level instruments, beginning at the four pumping stations in town. Wet ...

Tackling the world`s wastewater problems with a single pipe
As a 22-year old environmental engineering student, Enes Kutluca knew he wanted to develop something that could help every household in the world treat and reuse their own wastewater sustainably as well as efficiently. He came up with the idea of using a single pipe to treat the wastewater itself, instead of just being used as a means to channel this used water to treatment plants. After two ...
