Details of the Process
The effluent is subjected to pre-aeration , physic-chemical treatment & solid separation
, aerobic treatment as Activated Sludge Process to achieve the final COD of treated
effluent less than 250 mg/I.
The outlet effluent from tertiary treatment has Dissolved Solid (TDS) in the range
2500-3000 mg/I , which is more than the desired MPCB norms of <2100 mg/I . As the
MPCB consent conditions , the desired outlet TDS (i.e<2100 mg/I) will be achieved
by blending the treated sewage of less TDS . The required volume of treated sewage
(9330 m3/day) for blending will be sourced from 29 MLD Sewage treatment plant of
Ichalkaranhi Municipal Council.

Occupational Health and Safely
In CETP operations , the main safely hazards involve burns, shock , slips and falls. The proposed project may cause health problem like skin diseases to workers handling toxic effluent discharged by various industrial units.
The workers are subject to various diseases , including skin diseases. For protection from toxic material it may be made compulsory for all workers in the plant to wear masks and gloves while working in the CETP.
The plant workers may be encouraged to undergo health checkups at regular intervals in order to protect themselves from various diseases.
To meet the medical needs of the workers it is suggested that tie-ups with nearest hospital or primary Health center (PHC) may be made.
