Application occasions
JZL type precision drum filter is a kind of using gravity or pressure difference to make the suspension through a porous medium, interception of suspended solids in the suspension, to achieve effective separation of solid and liquid in the suspension of precision filtration equipment, in metallurgy, chemical industry, textile, printing and dyeing, electroplating, medicine, food and other industries have been widely used. Mainly applied:
1, the depth of municipal sewage treatment and the first level of upgrading transformation.
2. Recovery and recycling of water resources.
3. Pretreatment of tap water.
4. Recycling of suspended solids after solid-liquid separation.

Main features
The filter is made of 316L stainless steel with corrosion resistance, high strength and long service life.
The filter screen is resistant to impact load, and the equipment can operate normally under the condition that the influent SS is not higher than 40mg/L.
The filter screen is composed of independent mesh assembly, which can be independently removed, and the installation and maintenance are simple and convenient.
The treatment effect is good, the effluent water quality is good and stable, especially suitable for water quality improvement projects.
Can achieve 24 hours of continuous filtration, washing, filtration does not affect each other.
Flushing water consumption is small, impurities are not easy to accumulate on the filter screen, backwashing high-pressure water easily remove impurities. The water used is taken from the filtered water, and the water consumption is 0.3 of the treated water, which is much lower than the water consumption of other similar filters of 3% ~ 5%. Reduce the burden of post-treatment of flushing wastewater.
The head loss is small, generally not more than 0.3m, and the operation energy consumption is low.
The operation is fully automated, and has multiple protection, daily operation and management without special personnel.
Small footprint, short design cycle and construction cycle.
Working principle
JZL type precision drum filter is mainly composed of box, filter system, drive system, backwash system, automatic control system, etc.
JZL type precision drum filter is a continuous filtration equipment. Raw water (sewage) flows into the filter drum through the inlet of the water inlet pipe. The liquid level sensor will send out a signal to start the drive system to drive the filter drum to move and start the backwash pump at the same time. Raw water (sewage) using gravity or pressure through the high strength stainless steel filter, raw water (sewage) in the solid suspended solids are trapped inside the filter. The backwash pump extracts the filtered water, sprays high-pressure umbrella-shaped water column through the nozzle on the top of the filter drum, and washes the filter screen from the outside to the inside to remove the solid suspended solids accumulated on the inner surface of the filter screen. The washed fine particles are collected by the backwash water collection tank inside the filter drum and discharged from the equipment through the sewage pipe. When no water passes through the device, the device will automatically stop.
