Water quality problems such as muck buildup, harmful algal blooms (HABs), fecal coliform, and odors all have one thing in common, a dissolved oxygen (DO) deficiency referred to as anoxia. Sediment oxygen demand (SOD), from accumulated sediments, is the primary source of oxygen loss and subsequently anoxia in lakes and ponds. Anoxic Sediments are also the source of many water quality issues; muck accumulation from organic deposition greater than the rate of decomposition, results in the release of metals, such as iron (Fe) and manganese (Mn) nutrients like phosphorus which fuel algae growth, and malodors from hydrogen sulfide formation.
Water quality management strategies related to these common problems all focus on adding oxygen. OST is designed to exceed oxygen demands by dissolving oxygen directly into water via gas dissolution chambers.
OST is designed to dissolve all the oxygen generated from an on-shore compressor into water; therefore, eliminating and preventing the release of any bubbles. Bubbles rising through the water column induce mixing. Mixing in turn creates turbulence, which can exacerbate oxygen demands, resuspend sediments, and deteriorate water quality and clarity.
This highly efficient technology allows for a precise concentration of oxygen to be maintained continuously because it is automated to turn OFF or ON depending on in-lake oxygen levels. OST blankets the area of accumulated sediments often programmed/automated to maintain DO concentrations as high as 15-20 mg/L. High concentrations of oxygen provide exceptional water quality, not achievable with any other conventional aeration system in the market.
OST is a state-of-the-art technology designed to automatically treat the target problem areas directly when they need it most resulting in substanstial cost savings. Additionally, there is increased cost savings from less need of other surface applied products such as algicides.
