A broth,for example,Comparison of the high-frame and ultrafiltration membrane in the process,the recovery rate ingredients,water and waste treatment,and consequently confirm to ultrafiltration membranes,high-frame has the advantage of handled easily,less water and residual waste easy to deal.

In order to study the influences of the ultrasound on the dewaterability of the sludge,the combination of ultrasound technique and flocculant(PAM) was used for the sludge dewatering by plate-frame pressure filtration.

The hot rolling sludge treatment process consists of gravitational thickening,chemical conditioning and mechanical dewatering using an overhead-style automatic plate and frame filter press.

This paper introduces a new type automatic plate and frame filter press,which overcomes defects of old machine and will have bright prospects.

The experimentation of filtration sterilization of pale soy sauce by plate-and-frametype filter press and filtration mediun(diatomaceous silica)shows that it can remove the mycelidium in the liquid effectively.

The experimentation of filtration sterilization of pale wheat soy sauce by plate-and-frametype filter press and filtration mediun(diatomaceous silica)shows that it can remove the mycelidium in the liquid effectively.

The paper introduces the handling trouble methods of particle board single-opening press for oil cyclinder leak,press cyclinder cover screw bolt out-break,the reason analysis and handling method of up platen frame out-break.
