Filter element of high salt wastewater evaporator

Type: Sintered filter element

Material: SS304

Filtration accuracy: 25 microns

Purpose: high salt wastewater evaporator filtration

Aiming at the characteristics of high salinity and high concentration of chemical high salinity wastewater, based on the principle of evaporation, concentration and crystallization, the high salt wastewater evaporator adopts multi effect, MVR and forced circulation evaporation to concentrate and crystallize organic wastewater. After the salt in the concentrated solution is separated, it is recovered through the salt collector, and the concentrated solution is dried, recovered or incinerated,, The evaporated condensate is generally treated through subsequent biochemical treatment, which can realize the wastewater discharge standard.

Waste water evaporator type: high salt waste water evaporator

Principle of wastewater evaporator: according to the characteristics of high salinity and high concentration of chemical high salinity wastewater, based on the principle of evaporation, concentration and crystallization, the multi effect, MVR and forced circulation evaporation are used to concentrate and crystallize organic wastewater. After the salt in the concentrated solution is separated, it is recovered through the salt collector, and the concentrated solution is dried, recovered or incinerated,, The evaporated condensate is generally treated through subsequent biochemical treatment, which can realize the wastewater discharge standard.

Characteristics of high salt wastewater: high salt wastewater refers to wastewater with a total salt content of at least 1%, which mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salt, oil, organic heavy metals and radioactive substances). The chemical composition is complex and contains a large amount of organic substances, including organic solvents, organic acids, esters, ketones, phenols, etc., and the salt content is high, such as sodium chloride, ammonium chloride, ammonium sulfate, sodium sulfate or a variety of mixed salts, which is difficult to be directly treated by biochemical methods, and the physicochemical treatment process is complex and the treatment cost is high, It is recognized by the wastewater treatment industry that it is difficult to treat wastewater. The discharge of high salt wastewater has a great impact on the environment, so the pollutants in the wastewater must be removed before discharge.

Treatment process: in order to minimize the impact of such high salt wastewater discharge on environmental requirements, Bluslot adopts multi effect evaporation (or MVR evaporation) + crystallization system when treating such high salt wastewater. The distilled water produced is directly recycled or discharged up to standard; Demineralized waste can be further converted into dry crystals for recycling or further treatment, so as to achieve zero emission.

Design process: when designing the high salt wastewater evaporator, Kang Jinghui, the evaporator manufacturer, comprehensively considers many factors, such as the stable performance of the system, the economy of energy consumption, the treatment of scaling, the convenience of maintenance, the convenience of daily operation and so on, to treat the high salt wastewater, so as to ensure that the system meets the requirements of zero wastewater discharge.

Main features of high salt wastewater evaporator

• After evaporation, the wastewater can reach the reuse standard or discharge standard in one step;
• The two-step polymerization of wastewater concentration and wastewater salt crystallization is completed in different forms of evaporators respectively. The salt is separated from the crystallizer in the form of crystal, and the desalination effect is good;
• Combined with water quality and economic factors, multi effect or MVR evaporation crystallization forms are selected;
• Various materials and equipment can be customized according to user needs;
• The whole set of high salt wastewater evaporator realizes PLC automatic control, with flexible system operation and simple operation.
