1、 What equipment is a sewage evaporator?
A sewage evaporator is an evaporation device specifically designed for treating sewage. In the sewage treatment industry, sewage evaporators are common and commonly used equipment, which treat sewage through evaporation and are an important process in the industry.
The working principle of sewage treatment evaporator is based on evaporation, concentration, and crystallization. It evaporates and concentrates organic wastewater to separate salts from the concentrated solution, and separates and recovers saltwater. These concentrated liquids can be recovered through drying or directly incinerated.
The condensed water after evaporation undergoes subsequent biochemical treatment and further treatment to meet the standards for sewage discharge before it can be discharged. This is the working principle of the sewage evaporator.
The evaporation capacity of sewage treatment evaporators ranges from 1 ton to 30 tons per hour, so the total amount of sewage they can evaporate per day can be calculated.
2、 What type of sewage is mainly treated with a sewage evaporator?
In practical applications, not all sewage is suitable for treatment through sewage evaporators. Some wastewater may not be suitable for evaporation as a method.
In general, sewage evaporators are suitable for treating high concentration and high salinity wastewater. The higher the salt content and concentration in wastewater, the more effective the evaporation process is for treatment. Wastewater evaporation is based on the difference in boiling points between pollutants and water to achieve separation. Therefore, the larger the difference in boiling points between pollutants and water, the better the evaporation treatment effect.
If the wastewater contains salt, it is suitable for evaporation treatment. In addition, wastewater containing organic matter such as papermaking black liquor and garbage leachate is also suitable for treatment using evaporation method.
3、 What type of evaporator is used for sewage treatment?
The sewage treatment evaporator plays a crucial role in reducing environmental pressure and building a protective barrier for the environment.
If the sewage evaporator adopts multi effect evaporation technology, multiple evaporators will be connected in series for evaporation operation. This can reuse the heat energy of steam multiple times, avoid waste, and thus improve the efficiency of heat energy utilization.
If the MVR evaporation process is used for the sewage evaporator, it can recover steam multiple times to treat wastewater. The MVR evaporation process performs relatively well in terms of energy conservation and consumption reduction, and has a high level of automation control.
What type of evaporator is used for sewage treatment? This needs to be determined based on water quality, water quantity, site conditions, investment costs, and the requirements of the owner.
