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 BiotechnologyLotus Biotechnology is main

constituent responsible for degradation of organic matter (BOD & COD)

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.

UASB (Upflow Anaerobic Sludge Blanket Reactor) with Degassing

mechanism

UASB 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 20 - 25%.

Degassing Mechanism is removes dissolved gases present in the

UASB outlet. It also increases dissolved oxygen in the UASB treated

water.
