Issues raised:

　During the process of the wastewater treatment, large quantities of sludge are produced in primary sedimentation tank, biochemical reaction tank and secondary sedimentation tank. Such as:

·primary sludge

·activated sludge

·excess sludge

　In order to simply and economically treat with sludge during the further treatment processes, they must be thickened first.

  If without thickening and direct treatment, then:

·Further treatment process of watery sludge with only 0.5%DS is more difficult.

·Waste too many energy to heat up sludge to reach reaction temperature during the digestion operation.

·The voluminous digestion tank is required for nonthickened sludge quantities.

·Low gas yield due to poor sludge digestion.

Solution to these problems: use GLN—sludge thickener

Working principle:

·Wastewater treatment

·used for municipal and industrial wastewater flocculation

·sludge dewatering treatment process

·lv3/ lv4 municipal wastewater treatment

Drinking water purification

·water plants, which use the surface water as source, use this equipment can improve the effectiveness of purification and precipitation

Other industries

·SXZ could be used for treating wastewater, which was produced from chemical plants, electroplating, food and beverage industries, papermaking and ore smelting. Through the use of this device, can greatly reducing costs and the burden of the municipal sewage treatment plant.

·industrial wastewater treatment

Fundamental component:

·1 set of tri-cavity container devices consists with dissolution box, slaking box and storage box: associated with reinforcement pieces and support frames (made of polypropylene material (stainless steel optional))

·1 set of dry powder feeding device: equipped with inlet heater, shortage sensor alarm and vibrator.

·1 set of humidifier: equipped with funnel to moist, flowmeter and related connection accessories to dilute and wetting powder.

·2 electric mixers.

·1 set of controlling cabinet: for automatic control the entire system .
