  Usually   sewage treatment plants  use a two-step process of sludge concentration and sludge dehydration to reduce sludge volume and volume. For sludge with a moisture content greater than 98%, concentration should generally be considered to reduce the moisture content to about 96% to reduce the sludge volume and facilitate subsequent treatment. Sludge concentration mainly increases the solid content of the sludge through the gravity concentration tank. However, through the concentration tank, the volume is proportional to the concentration time, and the sludge is left to stand and concentrate for a long time, and the organic matter in it is easy to decay under the action of microorganisms. It smells bad and affects the sanitary environment of the sewage treatment plant. Therefore, generally after the moisture content is reduced to 94-96% through gravity concentration, a mechanical dehydration process with higher dehydration efficiency is needed to further process the s...

  In order to further improve the efficiency and management level of   sewage treatment  in sewage stations, realize real-time and continuous monitoring of sewage treatment processes, and accelerate the process of intelligent construction of mines, HZFilter Company's integrated fully automatic sewage treatment system is coming.   The  waste water purification system  uses advanced technology and equipment to monitor the operation status of the sewage station in real time, monitor the flow, temperature, suspended pollution, COD and other indicators of the sewage station in real time for a long time. Through intelligent control of the key treatment units and even the entire process of the sewage station, Automatically adjust parameters according to the incoming water load and operating conditions, reduce material and energy consumption, ensure the normal progress of the sewage treatment process and ensure that the water quality after treatment reaches the sta...

  As the name suggests, the dosing device is a mechanical   automated dosing system , which is widely used in   water treatment , petroleum, chemical and other industries. The operation process of the dosing device is very simple. It can be operated manually or through a controller, but when adding Corresponding debugging work must be done before the medicine device starts working. This is necessary to avoid unnecessary trouble!   1.Check whether the water source and power supply are connected.   2.Set the control button of the electric control box to the "manual" position, and check one by one whether each device is intact and whether the motor rotation is correct (the valve on the water inlet pipe should be opened when checking the rotation of the feed motor).   3.Use your hands to move the float ball up and down one by one to see if it can send out a signal normally, and then check whether the level alarm in the hopper can work normally.   4.Put dry...

  With the development of industrialization,   sewage treatment  has become an important environmental issue. In the sewage treatment process, dosing is a key link. The traditional manual dosing method is not only inefficient, but also prone to errors, which affects the water quality treatment effect. Therefore, the   fully automatic dosing device  came into being. The fully automatic dosing device is a device that integrates automatic control, metering, dosing and other functions. It can realize the automatic dosing of various chemicals in the sewage treatment process. Among them, the  flocculant dosing device  is one of the important components of the fully automatic dosing device. The flocculant can be added to the sewage in a certain proportion to cause the suspended solids in the sewage to condense into clumps to facilitate subsequent sedimentation and filtration. Another highlight of the fully automatic dosing device is the equipment used in the ...

  The function of  sludge concentration  is to remove part of the water in the sludge through gravity or mechanical means and reduce the volume; the function of sludge dehydration is to mechanically separate part of the interstitial water in the sludge to further reduce the volume. The moisture content of concentrated sludge can generally reach 94% to 96%. The moisture content of dewatered sludge can generally reach about 80%.   The sludge concentration and dehydration process should be comprehensively determined based on factors such as the sewage treatment process used, sludge characteristics, subsequent treatment and disposal methods, environmental requirements, site area, investment and operating costs, etc.   Main types and characteristics of concentration processes   The methods of sludge concentration are mainly divided into gravity concentration, mechanical concentration and air flotation concentration. At present, gravity concentration and mechanic...

  With more than 30 years of experience in the development and manufacture of   drum thickeners , Filter has gained in-depth expertise in sludge thickening technology. Rotary drum thickeners for sludge thickening are considered a simple and effective sludge thickening solution prior to the dewatering process and can handle 15 to 180m³ of biological sludge per hour. Due to their simple design and small footprint, drum thickeners for   sludge thickening  are easy to install and require little supervision and maintenance.   Rotary drum thickener  for sludge thickening before dewatering   The drum thickener is used for sludge concentration.

  The   central drive sludge scraper   adopts central drive and suspension type. After the sewage flows into the diversion tube from the inlet pipe under the working bridge and diffuses, it flows out evenly and radially to the periphery. The suspended sludge is deposited on the bottom of the pool after sedimentation. The drive The device drives the central vertical shaft to rotate, and drives the scraper arm and scraper plate to rotate. After scraping the sludge from the periphery of the pool to the central sludge collection tank, it is discharged out of the pool through the sludge discharge pipe based on the hydrostatic pressure in the pool. The skimming device skims toward the edge of the pool, and then scrapes the slag rake into the slag discharge hopper and discharges it out of the pool; while the supernatant liquid overflows into the outlet water tank through the triangular outlet weir plate and is discharged.   Main features of the equipment :   The drivin...
