A complete pretreatment and backwashing system is added on the basis of the original process of sand and stone wastewater treatment. By changing some main design parameters (such as surface hydraulic load, sedimentation time, etc.) and adopting advanced wastewater treatment equipment, t
The plate& frame filter press consists of base frame, filter plate, filter frame, pressing system and electric control cabinet, and the filter chamber consists of 2pcs filter plates pressing 1pc
1. Pretreatment stage The solid content of the original slurry is generally low, and the slurry concentration or other means must be used to increase the slurry concentration to reduce the treatment cost. The commonly used pretreatment method is: mixing the concentrated sludge with the high-molecular flocculant,
Damaging out of balance pressure is determined when thick and thin filter cakes are discharging from the filter platepack. This condition should be corrected as soon as possible to prevent filter plate damage. Normal low pressure differentials occur regularly and will flex the plate web within the design parameters. This flexing does not overstress the plate web and is no
Belt filter press is a continuous operation sludge dewatering equipment widely used in municipal wastewater, stone and sand wastewater, Tunnel sludge etc., it brought ideal sludge dewatering effect. Now, we will briefly introduce the capacity of belt filter press.
As for the users who didn’t applied the filter press, all the filter press could be called plate&frame filter press. Actually, the filter press could be separated in several types based on different working condition requirements or equipment structure. As the developed demand for higher efficiency of mordernized industrial prodution, many cons of plate and frame filter press can not meet the customers’ application. These cons mainly about t
