6 Lotus LCST Process“Lotus LCST (Low cost Sewage Treatment)” a new technology introduced by Lotus Environment Technology Pvt Ltd (LETPL) considering less capital investment, less power requirement, low maintenance, less manpower requirement, low operating cost and most important is very good outlet quality of treated sewage.Lotus LCST Process is combination of pretreatment, biologically enhanced primary treatment and Biological Treatment (UASB) followed by degassing mechanism. This process is highly suitable for low strength wastewater especially domestic sewage. Lotus Biotechnology is main constituent responsible for degradation of organic matter (BOD & COD)
7 Lotus LCST Process Type Lotus LCST Process “Rural”Lotus LCST Process “Urban/Municipal”
8 Essential Components of Lotus LCST Process (Rural) 1) Pretreatment.ScreeningGrit, Oil & Grease removalEqualization2) Biologically Enhanced Primary Treatment.Primary Tube Settling Tank (using Lotus Biotechnology)3) Secondary (Biological) Treatment .Root Zone Technology4) Sludge Treatment.Sludge Holding Tank, Sludge Dewatering Systems, Sludge Drying Beds

10 Pretreatment 1) Screening: Removal of floatables like clothes pieces, plastic bags, pouches etc using manual or mechanically raked screens.2) Grit, Oil & Grease removal:Removal of grit, sand, debris, fat, oil & grease using density differences of materials. FOG removed by skimmers & grit collected at bottom.3) Equalization:Equalizes sewage flow as well as Physico-chemical & biological parameters like pH, BOD & COD.
11 Biological Enhanced Primary Treatment Biologically Enhanced Primary Tube Settling Tank.Removal of BOD, COD & TSS using Lotus Biotechnology capable of removing 75 to 80% organic matter (BOD, TSS & COD)Raw Sewage from Equalization TankPrimary Clarified Water to Root Zone BedLotus Biotechnology75 to 80 % reduction of organic loadPrimary Sludge to Sludge Handling System
12 Secondary (Biological) Treatment Root Zone TechnologyRoot Zone Treatment System are planted filter-beds consisting of sand/gravel/soil. It uses a natural way to effectively treat sewage. It removes % of organic load (BOD & COD).phytoremediationPhragmites australis

18 Secondary (Biological) Treatment UASB (Upflow Anaerobic Sludge Blanket Reactor) with Degassing mechanismUASB uses an anaerobic process whilst forming a blanket of granular sludge which suspends in the tank. Wastewater flows upwards through the blanket and is processed (degraded) by the anaerobic microorganism. It reduces organic load by %.Degassing Mechanism is removes dissolved gases present in the UASB outlet. It also increases dissolved oxygen in the UASB treated water.
