Water Treatment & Recycling Solutions

Reduce, Reuse & Recycle

Water Crisis!

Haryana vs Delhi

Tamil Nadu vs Karnataka & Kerala

Sharing of River Waters

Total sewage water in Class I and II Cities India ◦ 38254 MLD◦ Only 11787 MLD (35%) treated

Current Scenario◦ Increase in demand and cost of water◦ Stringent waste water disposal norms◦ Increased contaminants from industries◦ Urbanization leading to large Sewage generation◦ Untreated sewage leading to severe water pollution

severely impacting ground water availability & quality.

RECYCLE WATER

ONE IMMEDIATE SOLUTION

At least 50 % of Water usage in urban areas – flushing / landscape maintenance / facilities washing

This 50 %+ water can be reclaimed and reused!

Leave behind good water for the generations to come

Coarse Screen / Fine Screen Oil Separator Pre Treatment in Equalization tank

◦ Removal of Suspended Solids, Oil & Grease, equalization for uniform flow. Addition of Lime and Enzyme

Primary Clarification – Contains Parallel Plates◦ Flocculation ◦ Addition of Caustic, PAC and organic polymer

Bioreactor (Patented design) – Contains Bio Media in Bio wheels◦ Specially developed bacteria eat up organic matter including

dissolved pollutants under Aerobic conditions◦ Bacterial augmentation with enzymes to produce required Bio

Film

ENZOTECH PROCESS

Second Clarifier (Biofiltration) (Patented design)◦ Contains Floating Media Bed◦ Dispersed Bacteria and minute organic flocks removed by Bio

Filtration Ions Chamber

◦ Pathogens killed by disinfectants Sodium Hypo Chlorite and PAC Filtration(Sand Filter, Carbon Filter)

◦ Removes remaining suspended and dissolved compounds Sludge Bed

◦ Sludge generated is sent by gravity to the sludge bed.

◦ Alternatively Filter Press or Centrifuge arrangement could be provided

ENZOTECH PROCESS Contd….

Improvement of Primary clarification, Bioreactor and second clarifier to reduce size and increase efficiency of three process.

Emphasis given to study of water chemistry and microbiology to increase efficiency of treatment to 97%.

Low power consumption Low sludge generation.

Minimal chemicals are required for Disinfection function.

Low operation and maintenance cost : Rs.0.15 to Rs.0.20 per liter.

Easy installation and easy retrofitting in existing treatment plant.

Low sludge generation.70 kg /7000 liters for 300 KLD,120 Kg/12000 liters for 500 KLD.

Flow variation will not affect efficiency of treatment of plant.
