The ILD Purpose1. Reduce the toxicity or negative
impact of the Domestic waste water.
2. Treatment starts at source, in pipelines before it reaches central collection point.
3. Waste water is transformed to safe irrigable water.
Domestic Waste Water : Prime ConcernsBiological Oxygen Demand & Chemical Oxygen Demand
Suspended SolidsNitrogenPhosphorusColiforms
Working of In-line Digestion (ILD)Selective Enzymes which are naturally occurring biodegradable proteins, are formulated into sustained release enzyme packs.Reintroduction of enzyme packs every 6 months at the source of domestic sewage to digest the waste in the water.
Existing Domestic sewage treatment plantsCapital intensive technologyLimited to design parameters – can’t treat
beyond stipulated limitsEnergy dependentCan’t keep pace with ever increasing
populationHigh maintenance technologySubject to depreciation and corrosionRequires highly qualified personnel
ILD working
Positioning of ILD unit
Reed Bed filtration for the final removal of TSS and dissolved N and P
Water can be recycled for irrigation
Waste in the underground sewerage pipeline is digested by the enzymes of the ILD unit
Position digestion enzyme packsAt critical junctions in the system
Further from this point water can used for irrigation
Reedbeds will remove TSS and Dissolved N and PWaste in the pipelines is
being digested by the enzymeprior to entry to the aerationponds

Advantages of ILDNeeds 40% less capital investment in
comparisonAdaptive and flexible designs to ongoing
changesElimination of Energy dependencyEasy to install and operate technologyDecentralized in a way to match population
demand Significantly lower maintenance Enhance the life of installed pipelines
Enzyme PackThe Enzymes present in the packs are
able to withstand exposure to several harsh chemical present in Domestic cleaners.
Packs are designed for sustained release of enzymes, even an occasional overdose/exposure to disinfectants will not affect its working.
Use of ILD system in non-piped sewage water treatment (Septic tanks)Tailor made Enzyme packs designed to treat
waste waters of stand alone septic tanks receiving upto 5000 liter per day.
To be placed at the inflow of the septic tank or simply submerging a pack in the septic tank’s first chamber.
Will remove foul odors and sludge buildup.
Has to be replaced every 6 months.
