Technologyoverview

Thistechnology incorporates reaction tank, mud membrane filter and tubularmembrane, and combines chemical reaction process, coagulation and clarificationprocess, filtration and adsorption process as well as ultrafiltration membraneprocess, thus to simultaneously achieve hardness removal, desilication, heavymetal removal, SS removal and a variety of other functions.

Mud membrane filtration has following features:

ü  Wastewater is filteredthrough a suspended mud layer which is formed under hydraulic force

ü  Adsorbing organics, suspendedsolids and other impurities in wastewater by such principles as staticelectricity and net trapping of high-concentration sludge

ü  High concentration ofmud membrane sludge

Tubular membrane has the following features:

ü  High strength, acidand alkali resistant

ü  High throughput

ü  Pollution resistant

ü  Strong, durable andlong service life

ü  Strong adaptability,suitable for peak operation

ü  No occurrence of laterprecipitation and flocculation

Technicaladvantages

Ø  Having shortened the system’sprocess flow

Ø  Having reduced the system’sfootprint

Ø  Having improved the softeningefficiency, quality of produced water is good and stable

Ø  High sludgeconcentration, no need to set up sludge thickening tank, small total volume of dischargedmud

Ø  No consumption ofchemicals such as coagulants and flocculants

Ø  No need of a largeflow of water to backwash and low self-use water ratio

Ø  Can achieve fuzzycontrol for softening and filtering

Applicationfields

Suitablefor treatment of high-hard, high-silicon, high-heavy metal and high-SSindustrial wastewaters, such as RO concentrated water, desulfurized wastewater.
