Other Details

Our clients can avail from us a wide range of combines wastewater pre-treatment Units. This unit is mainly fed with wastes, with the help of pump or gravity. Further, the pump or gravity is fed into the unit through a fix pipe system such as wastes, passing through the screen basket and are screened, thus, the bigger solid particles are removed. After this, the effluents pass in the tank (hopper) section, where finer solids particles are allowed to settle down and are further removed by a low rotating shaft-less screws system. Being an optional, the unit can also be designed with an oil/grease removing system.
 
The range of combined machines is designed to carry-out two functions at the same time:

• Sand removing
• Oil/Grease removing
• Screening
• Washing/compacting of solid removed
• Sand/grit separation
• De-greasing

 
Furthermore, the wastes go into the machine with the help of a fix pipe and reach the tank, where are allowed to settle down. Sands are then removed by a shaft-less screws system and at the same time, greases are also removed by the grease/oil removal system rack, provided with a blowing air system.

Main advantages:

• Odor-free
• No clogging
• Low maintenance and operation costs
• Low room needed
• No construction works needed
• Easy to install and operate
• Very low residual organic content in the washed out solid
• Volume reduction (up to 40%) of the washed out solid
