High salt wastewater evaporator

1High salt wastewater evaporator-Overview

Principle of wastewater evaporator: The high salt wastewater evaporator is designed for the characteristics of high salt and high concentration in chemical wastewater. Based on the principle of evaporation, concentration, and crystallization, it adopts multiple effects MVR、 Forced circulation evaporation is used to concentrate crystalline organic wastewater. After separating the salt content in the concentrated solution, it is recovered through a salt collector. The concentrated solution is then dried and recovered or incinerated. The condensed water after evaporation is generally treated through subsequent biochemical treatment, which can achieve the standard of wastewater discharge.

2、 Characteristics of high salt wastewater:

High salt wastewater refers to wastewater with a total salt content of at least 1% by mass, mainly from chemical plants and the collection and processing of oil and natural gas This type of wastewater contains various substances, including salt, oil, organic heavy metals, and radioactive substances. The chemical composition is complex and contains a large amount of organic compounds, 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 various mixed salts. It is difficult to directly treat by biochemical methods, and the physical and chemical treatment process is complex and the treatment cost is high. It is a well-known high difficulty wastewater in the wastewater treatment industry. The discharge of high salt wastewater has a huge impact on the environment, so the pollutants in the wastewater must be removed before discharge.

IIIHigh salt wastewater evaporator-Main features

1. Wastewater can be evaporated to meet reuse or discharge standards in one step;

2. The two-step aggregation of wastewater concentration and wastewater salt crystallization is completed in different forms of evaporators, and the salt is separated from the crystallizer in the form of crystals, resulting in good desalination effect;

3. Considering water quality and economic factors, choose evaporation crystallization forms such as multi effect or MVR;

4. Various material equipment can be customized according to user needs;

5. The entire high salt wastewater evaporator is PLC controlled, with flexible system operation and simple operation.
