1)The type of solids and particle size distribution
2) The flow rate of Slurry Pump
3) The length and diameter of your bore
4) The tank volume you will need

Compared with Mud system which used for Oil/Gas drilling. Mud system for HDD usually have a much smaller treating capacity and a compact design. The first step of choosing a right mud system is determine the treating capacity of the mud system you will need. GN Solids Control as a leading Mud System manufacturer. They can provide standard 200GPM, 350GPM,500GPM,800GPM,1000GPM,mud system. When deciding the size of a mud system that you will need. It is best to base it on 1.25 to two times the amount you are pumping. For Example: If your Slurry pumping flow rate is 250 GPM, you would want to choose a 500GPM unit. The second step you should consider how much screen surface you need and what kind of shale shaker you want. The more screen surface area you have means more volume you can clean. Third step you should consider how many Cones you need and what size. The cone size either be 4,5,10,12 inch. Each size cone has a micron cut point,which is the size of the smallest particle that the cone can pull out. Fourth step you should conside the mixing unit, the size of hopper, and tank volume. etc.
