PRODUCTS

High salt wastewater refers to wastewater containing organic matter and at least total dissolved solids (TDS) with a mass fraction greater than 3.5%. Due to the presence of organic pollutants and a large amount of soluble inorganic salts such as Cl -, Na+, SO42-, Ca2+, etc. in such wastewater. So, this type of wastewater is generally the limit of biochemical treatment.

Equipment Process

Selection of biological treatment process for high salinity wastewater: The biological treatment process for high salinity wastewater is basically the same as the ordinary biological treatment process, mainly including regulating tank, aeration tank, secondary sedimentation tank, sludge reflux, excess sludge dewatering, and adding nutrients.

Equipment Advantages

Not afraid of the cold, beneficial for insulation

The treatment of high salt wastewater is buried underground, which is beneficial for insulation. It can still operate normally in cold seasons in the north, without disturbing people`s noise and imperial flavor
High degree of automation

High degree of automation, unmanned, automatic operation, faults, easy for daily management
Low operating costs and energy consumption

Low operating cost, large gas volume, lower energy consumption than other gas products, small bubble diameter, more dissolved hydrogen, high oxygen utilization rate, therefore intermittent aeration can be used, with ultra-low power consumption
High efficiency and short cycle

High pollutant degradation efficiency and short debugging cycle
