Seawater Desalination and Economic Efficient Treatment of Waste Slag
As the world’s population grows and the consequent demand for freshwater in municipalities, agriculture and industry increases, the challenge of innovative technologies to ensure that global water demand is met increases accordingly. This is because the demand for freshwater continues to increase, while available freshwater is decreasing accordingly, and climate change and environmental pollution are further exacerbating the worldwide water crisis. Therefore, the extraction of drinking water from brine is becoming a trend. With the help of powerful centrifuges, this horizontal centrifuge is used to design the desalination process of seawater in an economically and environmentally friendly way.
Three Most Important Seawater Desalination in Seawater Desalination and Economic and Efficient Treatment of Waste Slag
As the world’s population grows and the consequent demand for freshwater in municipalities, agriculture and industry increases, the challenge of innovative technologies to ensure that global water demand is met increases accordingly. This is because the demand for freshwater continues to increase, while available freshwater is decreasing accordingly, and climate change and environmental pollution are further exacerbating the worldwide water crisis. Therefore, the extraction of drinking water from brine is becoming a trend. With the help of a powerful horizontal centrifuge, this kind of horizontal centrifuge can be used to design the desalination process of seawater in an economical and environmentally friendly way.
Three of the most important processes in seawater desalination are:
RO-reverse osmosis (membrane process)
MED-multi-effect distillation
MSF – Multistage Flash
Evaporators are used in MED and MSF processes. They work in vacuum to achieve optimal performance efficiency. In all cases, vacuum is created using a multi-stage steam jet vacuum pump. These vacuum pumps and corresponding condensers are the organic components of evaporation equipment, so they are becoming the focus of attention.
Reverse osmosis (RO) is the most commonly used method for desalination of seawater. In order to remove insoluble substances from seawater, flotation or ultrafiltration devices are usually installed upstream of the processing and installation equipment. This will produce sediment and backwash water, which must be treated as organic pollutants.
Reducing the volume of waste can reduce the cost of disposal and transportation.
The use of GEA horizontal centrifuge can effectively reduce transportation and disposal costs, because the machine can reliably separate the residue into solid substances and reusable water. By virtue of their strong dehydration ability, they can concentrate solid substances up to 25% of dry substances, which can greatly reduce volume and accordingly reduce disposal costs.
Maximum reliability through reliable design
In order to achieve the goal of permanently avoiding corrosion even in seawater with very high chloride content, we use only high quality materials to design horizontal centrifuges. Therefore, all components in contact with the product are generally made of double steelmaking/super double steelmaking, with the highest reliability.
