LOW COST DUAL TAPERED FLOCCULATOR IN THE PROCESS OF WATER TREATMENT

The invention, 'Low Cost Dual Tapered Fiocculator In The Process Of Water Treatment' is a device to be used in the process of water treatment, which is a modification of conventional (single) tapered fiocculator. The invention consists of 2n+l baffled channel flocculators arranged in series, (n being a positive integer). The number and spacing of the baffles in each of the channel vary to impart the required velocity gradient G to the flowing water in the baffled channel fiocculator, the magnitude of G decreasing from the first baffled channel fiocculator to the last i.e. (2n+l)th baffled channel floccualtor while the detention time t of the flocculatrion in each baffled channel floccualtor increasing from the first to the last i.e. (2n+l)th baffled channel fiocculator. Thus if G1, G2, G3, G4 G(2n+1) are the velocity gradients and t1, t2 , t3, t4 t(2n+1) are the corresponding detention times in the 1st, 2nd, 3rd, 4th (2n+l)th baffled channel flocculators respectively, then Gl>G2>G3>G4 >Gn >G2n+l and t1
