EcoStorm plus 400 : Stormwater Filtration System (for the removal of sediments, heavy metals and nutrients)
รายละเอียด:
See why ecoStorm plus is the most cost effective stormwater fltration system on the market,setting new standards for stormwater regulatory requirements.
• In addition to fltration, the system utilizes chemical transformation, precipitation and sorption (ion exchange) to remove a variety of pollutants (heavy metals, hydrocarbons) from stormwater
• More effective and affordable than conventional flters utilizing stainless steel, activated carbon or zeolithes
• Upstream sediment removal combined with self-cleaning flters reduces maintenance intervals and costs
• Easy installation saves time and money — single-structuredesign comes pre-assembled to jobsite, reducing footprintand excavation costs
• Has undergone extensive laboratory and feld-testing with proven results
• Patented concrete flters can be modifed to accommodate variousapplications and fowrates
ecoStorm plus Treatment Process
All ecoStorm plus units are equipped with a central overfow and maintenance pipe to
handle peak fow rates and allow access to the sediment storage chamber. While
ecoStorm plus is typically designed for gravity treatment of stormwater drainage, it
has the fexibility to accommodate other methods of pollutant delivery. The patented
concrete flters can be modifed to accommodate various applications and fowrates.
Sedimentation
Sediments are removed from stormwater by gravitation and trapped in the base section
of the ecoStorm plus unit. A small amount of sediment will accumulate temporarily on
the lower surface of the flter (PlusFilter). The design of the ecoStorm plus system allows
self cleaning.
Filtration
Vertical fltration in the pollution control pit and constant immersion in water of the
PlusFilter prevents formation of a flm on the lower side of the flter, which might
otherwise lead to clogging.
Adsorption
Pollutants like hydrocarbons and dissolved heavy metals are adsorbed by the modifed
porous concrete surface.
Chemical precipitation
The PlusFilter buffers the pH of the stormwater, which is typically acidic, hence
promoting precipitation and accumulation of dissolved substances. The fne pores of
the flter allow water to seep slowly through the media providing greater opportunity for
interaction between water and the alkaline composition of the flter.
