Equipment Introduction

Fiber rotary filtration tank is the sewage depth filtration equipment independently developed by Thunip, mainly used for removing SS and TP, applied to the depth treatment of sewage, water supply treatment, water reuse, steel mills, electric power plants, chemical plants, circulating water treatment, oily wastewater treatment, and the thick water treatment after the membrane, etc., which is the key technical equipment for upgrading and transforming the wastewater treatment to reach class IV water body, and promotes the technological progress of the industry. The equipment has been successfully applied in more than 500 municipal sewage treatment plants and industrial enterprises in more than 20 provinces and cities, such as Beijing, Tianjin, Jiangsu, Zhejiang and Shandong.

Advantages of the equipment

Fiber rotary disc filter pool through the fiber filter cloth as a filter medium, the use of back suction backwash, its unique design makes it has many advantages.

(1) three-dimensional structure: filter media placed perpendicular to the ground, fully utilize the space, save floor space and civil engineering investment, while the pool body has the function of sedimentation tank, increase the load tolerance; (2) new filter media, the filter media can be used to filter the water, and the filter media can be used to filter the water.

(2) A new type of filtration media: filtration fluff lay flat, increasing the depth of filtration, pore size of micron level, can retain the particle size of a few microns (μm) of the small particles, water quality and stability of the water are better than the granular media filtration tanks and screen filtration.

(3) New type of backwashing method: backwashing is carried out by means of backsuction, the backwashing intensity reaches dozens of times that of the traditional filtration tank, the suction force will stand up the filter cloth to ensure that there is no residue in the backwashing, and the instantaneous backwashing area is only 1% of the filtration area, so it can realize continuous filtration; (4) Stable quality of the effluent.

(4) Stable water quality and shock load resistance.

(5) Low idle rate of the equipment, low total installed power, saving power consumption; (6) Small backwash water volume, low total installed power, low total installed power, saving power consumption.

(6) Small amount of backwashing water, small impact on the pretreatment process; (7) Simple and convenient maintenance; (8) Easy to install and maintain.

(7) Simple and convenient maintenance

(8) Automation of operation, unattended operation can be realized.

(9) Short design and construction period.

(10) Accidents in the pre-filter treatment system have less impact on the filter tank, and faster recovery.
