Modernized oilfield water settlers are available in the following configuration: horizontal tank, set of instrumentation and automation equipment, internal settlers for water treatment and an upper cap for collecting and draining of recovered oil.
Dimensions and technological volume are determined depending on capacity, physical-chemical properties of oil, oilfield water, mode of operation and quality requirements for water treatment.
Internal anti-corrosion coating of equipment is applicable as protection against corrosion. Settlers designed for operating environment containing corrosive components (including hydrogen sulphide) are packages with internal equipment made of stainless molybdenum steel.
The automation system provides measurement, control and archiving of the following technological parameters: temperature, pressure, phase separation level "oil- water".
