Block-modular technological complex for oil-water separation STK-10

The company ECOservice-NEFTEGAZ suggests the block-modular technological separation complex (STK). The complex is for sewage water treatment -separation them to two fractions: oil products and clean water - and for the separation of the solids from the oily water. The block-modular technological separation complex (STK) is supplied in block sets having all needed technological and auxiliary equipment for automatic mode of operation. The equipment is housed in two blocks with dimensions 12 x 2,5 x 2,9m. This separation complex can be used: in sea ports for separation and treatment of bilge...

Operation description of the «STK-10» By force of the supply pump feeding oily water goes to the preparation system consisted of coarse-mesh filter and steam-water heat exchanger. Coarse-mesh filter is supposed for the equipment protection from the solids with dimensions more than 10 mm. Large size solids are collected by the special netted catcher which must be cleaned in case of actuation of the pressure difference transmitter. After filtering the oily water goes to steam-water heat exchanger for heating to the predetermined temperature (55…85 °C). Saturated steam generated by steam...

Clean water after the separation comes to tank for flushing water. Residual oil concentration in the treated water is controlled by special transducer. In case of the oil concentration more than 15mg/l the water automatically reverses to the first input of the complex. The tank for the flushing water is used for the treated water collecting. One part of this water is used for the solution preparation system and another one for the equipment flushing. At operation of the complex the clogging by solids of the separator and filters gradually takes place. The automatic regeneration of the...
