STORMPILLOW TECHNOLOGY - FILTRATION SYSTEM FOR STORMWATER TREATMENT OF RAINFALL RUNOFF

The new system, Stormpillow, deals with contaminated runoff stormwater before it goes to the drainage channel and water bodies. A well-designed technology is fitted into a drainage inlet without modifying or manipulating the drainage or hydraulic infrastructure architecture. The Stormpillow design is adaptable to any size or shape of drainage architecture. Most pollutants such as hydrocarbons, microplastics, microplastic, heavy metals, coarse and small debris, and dissolved ones are removed by taking advantage of the filter media composition in the bag (pillowcase).The main advantages of the system, which distinguish it from other similar systems on the market, are increased hydraulic efficiency, extremely low operation and maintenance (O&M) costs, ease of installation and maintenance, adaptability to any size and shape of the drainage system of the catchment, and the presence of the entire treatment media (granular activated carbon, zeolite, and perlite) in the pillowcase, which improves treatment efficiency. These advantages distinguish the system from other filtration technologies on the market.The technology has a well-designed overflow mechanism equipped with traping mesh (capturing debris and other coarse materials associated with the stormwater) that ensures the system's high efficiency in the face of high stormwater intensity and frequency.In addition to being very easy to install, build, and maintain, Stormpillow is also quite relatively affordable. It is not only adaptable to any size and shape of the drain's inlet due to the highly practical design of Stormpillow's body (guiding frame), but there is also an adjustable design that provides the possibility of being modified on the site in the occasion that there is any error in the measurement of the dimension of the drain inlet or any other obstacle to setting up Stormpillow.As a result of the filtering materials that are used in Stormpillow, contaminated stormwater runoff may be addressed on a large scale without having to take into consideration the hydraulic structure architectural design. In addition to being very effective at preventing pollution, the design of the overflow decreases the likelihood that polluted runoff will either be diverted around the system or overflow.
