Ceramic Membrane Application

Separation of liquids and solids; separation of oil and water; separation of liquids and liquids; (especially for filtration food and beverage industries, chemical and petrochemical industries, pharmaceutical and mining industries.)

High Turbidity Water (HTW)

This type of water is common in rivers, lakes and dams and industrial wastewater the prevalence of grease, dyes, ink, metal cutting liquids, alkaline and acid processing stream, diary fruit juice clarification and food processing water containing residues from example, soy sauce and vinegars to fermentation of beer in breweries increases turbidity.

Formerly, when treating HTW a Flocculation-Sedimentation Method was used. This process can treat HTW to a degree, but its short comings are many. Firstly this process needs a large tank to be successful. Area in today’s world is often hard to come by and expensive, not to mention when clean is needed in an emergency in natural disasters, the above technology would also take to long to construct. Hence this is not a viable process.

Sand Filter data over an extended period indicated that whilst the treatment time was short，the treated water quality is not good. The turbidity of the product water was still high which meant it could not safely be used. The tests concluded that if the raw water had very high turbidity, it can block the filters in several minutes.

Ceramic Membrane filtration system transforms high turbidity water into clean water in 2 – 3 seconds.

As this kind of system is equipped with a back wash component, the unit cannot be clogged easily. After the initial investment, users can use this application for years without need of spending more money. It can specially meet the needs of building small tap water plant for factories, towns and farms.

Municipal Wastewater Recycling

India is a country where water is scarce. Municipal Sewage from Wastewater Treatment Plant can be converted into clean water with our ceramic membrane technology for recycling use. This is an excellent method in preserving the water sources of some cities where water is not readily available.  Output wastewater after Multi-media filter and organic membrane quality is very poor, turbidity reached to 300 – 500 NTU, oil volume is 5 – 10 ppm hence not good for recycling. CMs filtering system can effectively remove oil, dirt, mud and sand from sewage. Combine this with our RO system, recycling target can be reached.
