Ball valves have a spherical disc inside that controls the flow of water by rotating the handle, while gate valves have a gate or wedge that moves up and down to control the flow. Both types of valves are used to regulate the flow of hot water through the heating system and can be manually operated to adjust the temperature or shut off the flow completely. **

Additionally, the replacement of old pipes with newer, more efficient ones may also contribute to increased energy consumption, as the system may be able to operate more efficiently overall. **

Suspension filtration works by passing a mixture of solid particles and liquid through a filter medium. The solid particles are too large to pass through the filter, so they are retained on the surface or within the pores of the filter. The liquid, which is now free of the solid particles, passes through the filter and is collected on the other side. This process separates the solid particles from the liquid, allowing for the purification or concentration of the liquid. **
