The unit operation technique and application of filtration and membrane separation are very important at the chemical, food, pharmaceutical, raw material, biologicals, biotechnology process operation of concentration, extraction, screening, filtration, purification, dewatering, separation and drying application, up to now, they can not breakthrough and overcomed the cake filtration problems, So they are still hard to do wide, effective and automatic continuous process operation treatment and application (not automatic batched continuous operation treatment and application)

The new innovative self-flush filtration, membrane separation technique, design and application are controlled the the straining cake variation of filter media which can be functioned the filter media at constant clean membrane, constant cake filtration and dialytic osmosis unit operation for wide effective water, liquid, solids, powder, wastewater, products of automatic continuous process concentration, screening, purification, filtration, separation, dewatering and drying treatment and application

    purification, separation, dewatering, drying technique and application

2. The bio-purification operation of concentration, screening, filtration,

    purification, separation, sterilization technique and application  

         The unit operation of bioprocess treatment are applied to concentrate and

         extract the bio-molecules of biologicals, microbes, bio-matter, bio-enzyme

         and bio-substances to make bio-products, they are normally needed to keep

         the bio-activity for production, So it can not be broken the cell wall and

         destroyed the bio-molecules into inactive

         The conventional bio-process operation are easy to concentrate and extract

         the micron and submicron particles of 22~0.2 micron rating bio-molecules

         biologicals, microbes, bio-matter, and bio-substances effectively by the

         conventional centrifuge technique and application, but hard to concentrate

         and extract the particles size smaller than 0.1~0.01 micron rating molecular

         weight bio-molecules of bio-enzyme, bio-matter, bio-substances effectively

         for production by conventional centrifuge technique and application, except

         applied the molecular weight UF/NF membrane filter

         a. like green algae(chlorophyceae): the particles size at 0.5~20 micron are

            easy to be concentrated and extracted by conventional process treatment

         b. like proteinase, dehydrogenase, bio-dye: the molecular weight at 400~

             1000 MW are hard to be concentrated and extracted by conventional

             process treatment

     [The defect of conventional centrifuge, filtration, membrane separation

       trechnique, design and application applied at the bio-process operation]

       1. the conventional centrifuge, filtration, membrane separation technique, design and

          application are concentrated, extracted, screened, purified, filtered, separated all the

          substances of impurities, solids, suspended solids, reactive chemical substances,

          bacteria, virus, microorganisms, bio-molecules of biologicals, microbes, bio-matter,

          bioenzyme, bio-substances simultaneously, but hard to concentrate, extract, screen,

          purify, filter, separate the specific pure bio-molecules of biologicals, microbes,

          bio-matter, bioenzyme and bio-substances clear effectively

      2. the conventional centrifuge, filtration, membrane separation technique, design and

          application are already very hard to do effective bio-process concentration, extraction,

          screening, filtration, purification, separation, dewatering operation and application, 

          how to do more effective higher quality of bioproducts production

        [point]

       1. The micron, submicron particles size of 0.2~50 micron bio-molecules of biologicals,

           microbes are same as the particles size of 0.2~22 micron bacteria, algae, fungi, mold,

           spores, protozoans and suspended solids which are hard to be discriminated by the

           conventional centrifuge, filtration, membrane separation technique, design and

           application

       2. The ultrafine particles size of 100~1000000 MW bio-molecules of bio-enzyme, bio-

           matter, and bio-substances are same as the particles size of 0.1~0.001 micron virus,

           endotoxin, pyrogen, organic matter, chemicals, toxic matter, total dissolved solids and

           heavy metal which are hard to be discriminated by the conventional centrifuge,

           filtration, membrane separation technique, design and application

 The high quality of bioproducts manufactured and production are

  included the following point of unit operation step:

       1. high quality of bio-fermentation process operation step:

           The fermentation operation step are applied the aseptic water, raw materials, culture

           media and pure microbes for high quality pure bio-liquid and bio-solution production

       2. high quality of bio-process production operation step:

           The high quality bio-process operation step are applied to concentrate, extract, screen,

           filter, purify and separate the specific active pure concentrated bio-molecules of bio-

           matter, bio-enzyme, bio-substances, biologicals, microbes for production

       [point]

       The culture media, fermentation process operation and bio-production of specific bio-

       microbes are same as all the bacterial contaminations of gram positive bacteria, gram

       negative bacteria, pyrogenic bacteria, algae, fungi, molds, spores, protozoans, virus,

       endotoxin, pyrogen, If the process water, raw materials, culture media are not aseptic

       free and the bio-microbes not pure being contaminated all the bacterial contaminations

       of gram positive bacteria, gram negative bacteria, pyrogenic bacteria, algae, fungi, mold,

       spores, protozoans, virus, The bio-production are generated how much gram positive

       bacteria, gram negative bacteria, pyrogenic bacteria, algae, fungi, molds, spores, virus,

       protozoans, endotoxin, pyrogen contaminations are needed to be monitored, validated

  and evaluated
