Effluent characteristics ( as on Dec. 1998)

 

Sample specification	pH	SS	Alk.	BOD	COD	Cl-	S2-	Cr. Total
Raw effluent	8.6	1037	1310	1178	2408	3241	211	32.2
Final treated effluent	8.2	214	850	101	521	3219	102	4.1

All parameters except pH are in mg/l,

Measure(s) undertaken at CETP

• Bio-remediation technique being tried to restrict content of sulphides and chromium in effluent

Measures at industry level

• Six industries performing chrome tanning (raw to wet blue operations) have set-up chrome recovery plants(CRP)

.Pattern of cost sharing :                                 On the basis of raw water consumption / standard rate of effluent generation.
 
 
 
 
 
 
 

CETP at Kanpur, U.P.

Name of the project :                                                                    36 MLD, UASB Plant, Jajmau, Kanpur.

Members :                                                                                    354  tanneries,  Out  of  which 305  are active members
                                                                                                    which consist of 167 chrome tanning units,  35  vegetable
                                                                                                    tanning,    55 pursuing    both type of tanning and 48 units
                                                                                                    engaged   in leather splitting. Out of 305  active members
                                                                                                    6 are in large scale and remaining 299 in small or medium
                                                                                                    scale category.

Designed capacity :                                                                       36000 m³/d, consisting of mixture of tannery
                                                                                                    waste and sewage blended in 1:3 ratio.

Area of project :                                                                           30,000 sq.m

Cost of project :
 

Conveyance system :                                                                  Through 17.57 km long network, wherein majority is closed
                                                                                                  and some   of   the   portions are open channel covered with
                                                                                                  pre-cast  slabs. Flow is  facilitated  by   4  pumping  stations
                                                                                                  located at appropriate junction in the network

Treatment units :                                                                         Screen chamber - 4 nos; Grit channel - 4 nos.
                                                                                                  Equalisation tank - 2 nos; UASB reactors - 2 nos
                                                                                                  Collection well - 1 no; Diffuser - 1 no
                                                                                                  Dosing tank - 1 no; Clariflocculator - 2 no
                                                                                                  Sludge thickener - 1 no; Gas holder - 1 no.
                                                                                                  Sludge Beds

 

Sample specification	pH	TSS	VSS	BOD	COD	NH3-N	S2-	Colour
Raw effluent after equalisation	8.23	563	401	243	917	192	-	100
Final treated effluent	8.4	230	142	86	353	197	223	100-150
