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)

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.
Biological Enhanced Primary Treatment

Secondary (Biological) Treatment
Root Zone Technology
Root Zone Treatment System are planted filter-beds consisting of sand/gravel/soil. It uses a natural way to effectively treat sewage. It removes 20 - 25% of organic load (BOD & COD).

Secondary (Biological) Treatment
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.
