Stabilisation ponds also have the advantage of very low operating costs since they use no energy compared to other wastewater treatment technologies and only low-tech infrastructure (see also operation and maintenanceand ensuring sustainability). 1992; SASSE, 1998; TILLEY et al. Based on operational simplicity, low cost and high removal efficiencies (99% BOD5, suspended solids and coliform bacteria removal), AIWPS is highly recommended for up to 1000 mg/L BOD5 concentration. 12 0 obj Wind energy is one of the important auxiliary energy sources of the stabilization pond. They are semi-centralised treatment systems combined after wastewater has been collected from toilets (see also wastewater collectionand user interface). % The purified sewage is introduced into the artificial lake and used as a water source for landscape and sightseeing . Odor can become a nuisance during algal blooms or with anaerobic lagoons and lagoons that are inadequately maintained. N and P) and is therefore appropriate for the reuse in agriculture , but not for direct recharge in surface waters. endobj Aquatic plants that are present in the pond should also be removed as they may provide a breeding habitat for mosquitoes and prevent light from penetrating the water column.

The two lagoons are operated in series and cover approximately 26 acres. 6 0 obj Although effluent from aerobic ponds is generally low in pathogens, the ponds should in no way be used for recreation or as a direct source of water for consumption or domestic use. WSP are also recommended for the treatment in order to reuse the effluent in agriculture and aquaculture, because of its effectiveness in removing nematodes (worms) and helminth eggs (WHO 2006, Volume II), while preserving some nutrients. This is the Arabic version of the Compendium of Sanitation Systems and Technologies. Advantages Disadvantages Low energy usage (feeding by gravity) Robust against load fluctuations . <> They use less energy than most waste water treatment methods. 12 0 obj In a series of WSPs, the effluent from the anaerobic pond is transferred to the facultative pond, where further BOD is removed. `# ~a8ivHjy2_diw"sfGDl2lG] The main function of anaerobic ponds is BOD removal, which can be reduced 40 to 85 % (WSP 2007).
