Operating Instructions for Filter Press Filter Plate Quantity and Operating Limits The number of filter plates installed on the filter press must not be less than the quantity specified on the nameplate. The clamping pressure, feeding pressure, squeezing pressure, and feed temperature must not exceed…

(III) Filtration Process for Plate and Frame Filter Press Open the filtrate outlet valve, start the feed pump, and gradually open the feed valve while adjusting the return valve. The filtration pressure should gradually increase according to the filtration speed, generally not exceeding 0.6 MPa.

Operating Instructions for the Filter Press (1) Pre-Filtration Inspection Check the piping and connections Before operation, inspect all inlet and outlet pipelines and connections for any leaks or blockages. Ensure that the pipelines, filter plates, and filter cloths are clean, and confirm that the feed…

I. Filter Press Equipment Installation and Commissioning Design the embedded foundation holes according to the base dimensions provided by the supplier, using the two-stage grouting method. Ensure there is sufficient space around the filter press for convenient operation, inspection, and maintenance. The filter press should…

Operation and Precautions for Mechanical Filter Press in Wastewater Treatment Pressing the Filter Plates Connect the power supply and start the motor to press the filter plates tightly. Before pressing, check that the number of plates meets the required specification, that no foreign objects are…

The biggest difference between a trommel screen and other screening equipment is that it does not rely on a vibration motor to generate excitation. Instead, trommel screens are classified into shaft trommel screens and shaftless trommel screens according to their drive method. Shaft Trommel Screen:…

Water Level in the Saturation Tank of DAF System: During inspection, check the water level in the saturation tank through the observation port. Ensure the level is not so high that it submerges the packing layer (which would reduce air dissolution efficiency), and not lower…

Precautions for Commissioning the Pressurized Dissolved Air Flotation (DAF) System Pipeline and Saturation Tank Cleaning Before introducing influent water, use compressed air or high-pressure water to repeatedly flush and clean the pipelines and saturation tank until no clogging particles or impurities remain. Only then should…

Equipment Selection Small rectangular DAF tanks usually adopt a chain-type scraper. For large rectangular DAF tanks (recommended span ≤ 10 m), a bridge-type scraper is commonly used. For circular DAF tanks (diameter 2–10 m), a planetary-type scraper is suitable. Sludge Removal Efficiency If large amounts…

There are several types of DAF tanks available. The choice depends on the characteristics of the water to be treated, the treatment requirements, and other specific conditions. Common types include horizontal-flow and vertical-flow tanks, square and circular layouts, as well as integrated designs that combine…

Adjust the dosage of coagulant based on the flocculation condition in the reaction tank and the effluent quality of the DAF unit, taking care to prevent clogging of the dosing tank. Observe the water surface in the DAF tank. If large bubbles appear in the…

Dissolved air pump flotation technology is a new type of flotation technology developed in recent years. This technology overcomes the disadvantages of conventional DAF systems, such as the need for multiple auxiliary devices, high energy consumption, and the production of large bubbles in vortex flotation…
