A Next-Generation Overground STP System with Advanced MBBR + Filtration Technology
Ventilair Engineers Pvt. Ltd. (VEPL) introduces an innovative and uniquely engineered Plug-and-Play Sewage Treatment Plant (STP) – a Capsule-Type MSFRP (Mild Steel with FRP Coating) system that is superior to traditional FRP capsules. This over-the-ground STP unit comes pre-fabricated, pre-wired, and pre-tested, offering rapid deployment, low maintenance, and high performance for small to mid-sized establishments.
Unlike standard FRP capsules, VEPL’s MSFRP capsule is more robust, corrosion-resistant, and fully integrated with multi-stage treatment that includes settling, MBBR biological treatment, multi-grade filtration (MGF), activated carbon filtration (ACF), and sludge management with filter press. Ultrafiltration (UF) is also available as an on-demand final polishing stage.
