Sewage Treatment- Present ApproachBiological treatment for sewageBio-MethanationBio-Composting of solid sludge
HoweverThese approaches are not sufficiently
effective
Statutory requirements are not fully complied

Limitations of Conventional Microbial Treatments for STP
▼ Dependency on “mood” of microorganisms▼ Large land requirement▼ Inconsistency of results due to multiple factors▼ High maintenance costs▼ Depletes atmospheric oxygen, generates green house
gases▼ Spreads pungent smell, large quantity of solid sludge▼ Most of the plants are not scalable

Distillery Spent Wash Effluent-The
Challenge• Distilleries fermenting sugar cane molasses generate 8 -
15 liters of waste water per liter of ethanol produced.
• The Distillery spent wash (DSW) is characterized by being:Highly acidic Very High BOD and COD High recalcitrant organics with dark colour and severe
pungent smell.High concentration of recalcitrant COD persists even
after both anaerobic and aerobic treatments.Melanoidins and Polyphenolic complexes formed
during fermentation is not easily decomposed by any conventional treatment

Xerodrop Infrastructurefor drinking water from sewage• Sewage can be converted to drinking
water if appropriate infrastructure is created
• Singapore recycles sewage to drinking water
• Stringent quality assurance is required

XERODROP – Way forward
• XERODROP Technology is tested on various industrial effluents including power plants, fertilizers, pharmaceuticals, service stations, textile, dairy, Municipal STP, and many more
• Controlled treat ability test on a Pilot plant is advisable for all specific industrial effluents.
• Pilot plant of Xerodrop is available for technology demonstration at nominal charge.
