The technique consists of a new Dissolved Air Flotation (DAF) System, fine filtration, new membrane treatment and other physical / chemical methods, that can remove oil particles and suspended solids. Each unit can be made modular for different water quality treatment.
Oilfield production testing results in large oily-sewage, which is different from regular produced water. The water during production testing is short-term and discontinuous. In terms of this issue, Haimo ESG has developed a mobile water treatment equipment which could be used flexibly according to the customers’ demand. The resulting effluent is then ready for re-injection.
The wastewater containing oil firstly passes through the equilibrium tank skimmer unit to adjust flow rate and remove slick oil; then in the DAF unit, emulsified oil will be largely reduced; finally through the CMUF unit, most of SS and oil content of wastewater will be cleaned up to meet the 0.01μ m2 average air permeability standard of SY/T5329-2012.
High flexibility - the treatment can handle projects with variable flow rate and quality.
Skid-mounted plant, easy transportation and installation, flexible arrangement according to demands of clients.
Automation - compact, highly automated, integrated, less people dependent.
Good treatment of oily sewage containing highly concentrated emulsions.
