<p>Plant comprises a chamber with an inlet through which liq. to be clarified is supplied. The chamber is divided into two zones, one for flocculation and the other for pptn. of particles as the liq. rises in laminar flow via narrow channels. The liq. inlet is a divergent, conical diffuser with an included angle of 8-14 degrees. The flocculation zone contains a flow divider made of plates aligned with the direction of rising current and regularly spaced across the chamber. The downstream ends of the plates are forked at about 90 degrees with the 'V' open to the rising current. The plates, which should be parallel to each other, all lie in planes which are perpendicular to the axis of the inlet diffuser. Used for removing heavy concns. of suspended solids from industrial effluents e.g. mineral processing, etc. The installation is suitable for clarifying turbulent flow contg. >=2500-500 mg/l. of suspended solids, partic. as a pre-treatment upstream of filters or centrifuges. The construction is simple, inexpensive and the appts. is compact and highly efficient. It will produce a clarification of >=90-95 degrees.</p> |
