Lamella Cross Flow Separators

The Cross flow separator system permits simultaneous separation of floating and settling materials like oils, fibres, sand etc.. But are also individually applicable as oil and solids separators. The raw water containing oil and/or suspended solids passes in horizontal direction between the closely spaced plates in the plate pack. Completely laminar flow conditions are established while the water flows across the plate pack from the inlet to the outlet side. Laminar and stable flow conditions are essential conditions for the effective gravity separation of the water, oil and/or the suspended contaminants.

Oil separation

In the course of passing through the plate pack from inlet to outlet, the oil floats upwards info the tops of the corrugations and rises up the incline of the plate to the surface of the separator, where it is removed by a skimmer.

Solids Separation

The solids move towards the Bottoms of the corrugations and slide down the incline of ' the plate. From there the separated solids are collected in the sludge compartment of the separator to be partially dewatered and transported by a shaft less spiral conveyor and intermittently discharged through a blow-off valve (optional). Settled sludge cannot decontaminate the treated water. Oil and solids move in separate directions, but both perpendiculars to the flow of water, eliminating particle re-entrainment completely.

All K-Pack separators are custom built with respect to the number of plates in the pack, the length of the plates, the distance between the plates and the plate incline. The number and the length of plates is determined as a function of the raw water flow rate to be processed in the separator. The distance between the plates is depending upon the concentration of solids / sludge in the raw water. The incline of the plates is set between 45 and 60 degrees depending upon the general nature of the Oil and/or sludge, (density, viscosity, concentration).

The systems are fabricated in mild steel and other materials are available on request. The oil separators are standard with oil and skimpipe and 45 degree shaped compartment. The solids separators are optionally with a shaftless conveyor in the sludge compartment.

In the corrugation tops a very high oil concentration is established. This is the ideal condition for oil coalescing to take place (formation of large oil droplets out of many small oil droplets). In the corrugation bottoms a high sludge concentration is established. This is the ideal condition for particle agglomeration to take place (formation of heavy particles from small and relatively light particles)
