**3. Results and discussion**

#### **3.1 Neutralization decantation and precipitation**

High salt content in the hot brines may deteriorate electrolyte potential at low levels. The dissolved silisium contents may even bound bicarbonate and calcium rective component. Low level salt contents of Şırnak and Batman province will be highly advantageous for precipitation of heavy metals and metal cyanides (**Figure 5**).

#### **3.2 Microwave digestion with geothermal water- washing**

The required ozone dosage depends on a number of factors, most notably the type of wastewater treated. The Şırnak solid wastes can threaten surface water and groundwater resources. Strategies are needed to identify and solve local pollution

problems, and residents, businesses and industry need to be educated about the health hazards associated with untreated wastewater. Safe drinking water and proper treatment have been recognized as indispensable factors for sustaining life. Increasing poverty is exacerbated by factors such as increasing population growth and rapid urbanization, as well as hydrological variability and climate change. These socio-economic and environmental factors come about by increasingly valuing water and wastewater infrastructure. Reliable wastewater treatment systems serve together with the degree and quality of the wastewater, which determines the effects of these treatment plants on the environmental water resources released, as a good indicator of the level of development in municipal and public health. In the last few years, the amount of municipal wastewater generated has increased significantly due to the steady increase in the population with increasing dependence on decreasing water resources (**Figure 6**).

#### **3.3 Char carbon compost washing technology - sorbent applications**

The slurries is stand for 30 minutes after being conditoned. At the end of the period, the settled mud was removed by decantation method and dried.

The effluent by adding salts at concentrations ranging from 30,125 ppm to 1000 ppm, until the precipitates were obtained in sufficient quantities with pure water in the waste water.

The step wise washing cycle is practised in the geotermal waste water slurry: there is no water–effluent washing column unit connected to the waste sludge, and the washing sorbent bed contained one single microwave radiation column is used to wash in the three decantation washing norms: roughing, scraping and cleaning. The variation of the third cycle washing is also slowed recycling by microwave act.

The simple production presented as adapted and optimized depending on the target application. The main applications are briefly described in the following sections. Although this review only focuses on state-of-the art commercially available pellet plants, it should be noted that some prospective advanced applications for heat melting of binder are currently being studied, mainly in the form of prototypes or proof-of-concepts. These innovative applications include:
