2. The ILD Purpose 1. 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.

3. Domestic Waste Water : Prime Concerns Biological Oxygen Demand & Chemical Oxygen Demand Suspended Solids Nitrogen Phosphorus Coliforms

4. 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.

5. Existing Domestic sewage treatment plants Capital intensive technology Limited to design parameters – cant treat beyond stipulated limits Energy dependent Cant keep pace with ever increasing population High maintenance technology Subject to depreciation and corrosion Requires highly qualified personnel

6. 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

7. Position digestion enzyme packs At critical junctions in the system Further from this point water can used for irrigation Reedbeds will remove TSS and Dissolved N and P Waste in the pipelines is being digested by the enzyme prior to entry to the aeration ponds INLINE DIGESTION ENZYME PACKS WORKING IN THE UNDERGROUND SEWAGE SYSTEM. EXISTING AIERATION POND

8. ILD and Reed bed treated water

9. Advantages of ILD Needs 40% less capital investment in comparison Adaptive and flexible designs to ongoing changes Elimination of Energy dependency Easy to install and operate technology Decentralized in a way to match population demand Significantly lower maintenance Enhance the life of installed pipelines

10. Enzyme Pack The 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.

11. 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 tanks first chamber. Will remove foul odors and sludge buildup. Has to be replaced every 6 months.

12. Where to place Draynzyme Places where Draynzyme Can be placed in a Septic tank.
