Spherical Suspended Packing is also known as porous rotating spherical suspended packing,it’s a latest product among variety of packings,which was used for water treatment and a treatment technology of biomembrane.It has some characters,like solid structure,large specific surface area, drain directly,unfixed, bacterial growth quickly and not plug in the biological treatment of sewage.

The packing is made with injection polypropylene,there are two layers of spheres in inside which is rotary sphere and outside which is fishnet sphere.It can carry biomembrane and intercept suspension,other characteristics include srong adhesion force of bacteria, large specific surface area,high voidage,good chemical and biological stability, durability,not strip injurent,not pollute secondly,lock UV light,resistant to aging and stong hydrophilicity.During the procedure of packing use,the bacterial growth vegetated along,change easily, acid alkaliscence-proof,impervious to water flowing,long-lived,less remainder sludge and easy installation.

	QTL-150G This type was made by oneself of our company, Characteristic: plump, hardness,unbrittle and substantial;The raised screw thread burr in suface and core that increase the Specific surface area,besides,it can improve the oxygen utilization and bacterial growth quickly.
	QTL-150Z The structure of core is double-circle plastic ring changed by pressing plastic wafer,then press fiber of aldehydes or Dacron to the ring of circle, fasciculi may be symmetrical; Snowflake plastic bars in inside track not only can carry bacteria,but also cut air bladder effective,which can improve the oxygen utilization.
	QTL-150T Flexible filas in core show radiant state,water-air and biomembrane exchange and contact adequately, bacterias live on the each fila symmetrically and keep nicer life and interspace changeability,and that sphere and sphere will collide mutually between the role of the airstream in the process of running.This new type is more ideal,thanks to good metabolic of bacteria.。
	QTL-100S High treatment efficiency of water dues to inner plastic stip.
	QTL-80S High treatment efficiency of water dues to inner plastic stip.
	QTL-80X Core is made of fastening fibre thread, acid alkaliscence-proof,better elasticity, compressible, high voidage.
	QTL-80H Core is made up of small sponge parts,which is flexible, compressible and intercepting suspension stongly.
	QTL-70S High treatment efficiency of water dues to inner plastic stip.
