The HDD mud purification and recovery equipment is a device used to treat mud in the horizontal directional drilling (HDD) process. It physically and chemically cleans the mud to remove solid particles, dirt, grit and other impurities, and enables the mud to be recovered and reused.

The HDD mud purification and recovery equipment usually includes components such as coarse screen, fine screen, desander, desilter, suspended matter separator, chemical dosing system and mixing system. Among them, the coarse screen and fine screen are used to remove the coarse and fine solid particles, the sand separator and the mud separator are used to remove the sand and soil particles, the suspended matter separator is used to separate the impurities suspended in the mud, the chemical dosing system is used to add agents to promote the purification of the mud, and the mixing system is used to maintain the uniform suspension of the mud.

The HDD mud purification and recovery equipment has an efficient and reliable mud treatment capacity, which can meet the requirements of mud quality in the HDD process, but also reduce the impact on the environment and realize the effective use of mud resources.
