lagoon wastewater treatment system

Wastewater … Aerobic bacteria convert wastes into carbon dioxide, ammonia, and phosphates which, in turn, are used by the algae as food. The patented EDI Lagoon Solutions – Internal Separator (IS™) Solution system uses an innovative biological solids separator module to increase biomass concentration in a completely mixed cell by … Anearobic means “without oxygen”. Triplepoint’s rental lagoon aeration systems can be onsite within one week, complete with turnkey installation of aerators into the lagoon so you can be aerating in no time. Waste stabilization ponds (WSPs or stabilization ponds or waste stabilization lagoons) are ponds designed and built for wastewater treatment to reduce the organic content and remove pathogens from wastewater.They are man-made depressions confined by earthen structures. Typically the sludge will have a residence time or sludge age of 1 to 5 days. The top layer is called the aerobic zone, because the majority of the oxygen is present there. Odor can be a problem with anaerobic lagoons. It is a collaborative effort and one which we hope you find informative and helpful. Operation Assessment All lagoons should be desirable wastewater treatment systems… Lagoons experience cycles due to variations in weather, the composition of the wastewater, and other factors. It relies on evaporation as mode of disposal of wastewater. Domestic sewage from the home flows through a pipe to a lagoon, where physical, biological, and chemical processes provide treatment. Both these systems utilize fine or medium bubble diffusers to provide aeration and mixing to the process water. This … Our technology: optAER® Fine-Bubble Lagoon Aeration The Nexom optAER system is an efficient pond-based wastewater treatment solution used in a broad spectrum of applications. Like most natural environments, conditions inside a facultative lagoon are always changing. Aeration and Thorough Mixing for Lagoon Optimization Still a common method of BOD & TSS treatment, lagoon wastewater treatment systems continue to be a large portion of the wastewater market all over the world. However, in many cases odor can be managed through a variety of methods such as adding sodium nitrate, recirculating pond effluent, and through regular maintenance. A traditional lagoon system is a two part system. They are sometimes referred to as partial-mix or complete-mix lagoons depending on the extent of the aeration. There are many other aerobic biological processes for treatment of wastewaters, for example activated sludge, trickling filters, rotating biological contactors and biofilters. By … An aerated lagoon (or aerated pond) is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewaters.[1][2][3][4]. In addition, the sludge layer at the bottom is full of anaerobic bacteria, sludge worms, and other organisms which provide treatment through digestion and prevent the sludge from quickly accumulating to the point where is needs to be removed. This means that the chemical oxygen demand (COD) removed is relatively little and the effluent is therefore unacceptable for discharge into receiving waters. The need for a supply of supplemental dissolved oxygen typically occurs when biological treatment systems such as lagoons experience temporary overloads or equipment failure. Typically, remedies for lagoon problems are a fairly simple process. When soil conditions are not suitable due to slow percolation rates, a residential lagoon system is a good option. Wastewater Technology Fact Sheet Anaerobic Lagoons DESCRIPTION An anaerobic lagoon is a deep impoundment, essentially free of dissolved oxygen, that promotes anaerobic conditions. There are many methods for aerating a lagoon or basin: Ponds or basins using floating surface aerators achieve 80 to 90% removal of BOD with retention times of 1 to 10 days. Aerobic means “with oxygen”, and facultative means both with oxygen and without oxygen. The most common type of onsite wastewater treatment system used is a septic tank in combination with a drainfield. Anearobic bacteria convert substances in the wastewater to gases such as the odorous (rotton egg) hydrogen sulfide, ammonia, and methane.
