filtration resistance
1.Quantitative relationship between SMP and filtration resistance is R=1.76×1012(TOC)0.1914 . The test on resistance distribution shows the SMP is the main source of gelatinoids filtration resistance.
2.COS-2 is a graft modified product of cationic starch The mud characteristic of OGS-2 was evaluated in laboratory,the experimental results show that CGS-2 has the following properties:obvious filtration-reducing, reltively strong salt resistance and heat resistance abilities, and fairly good anti-collapse.
4.As a result, the electrostatic needle filtration fabric has higher purifying efficiency and lower resistance, but the purifying efficiency would decrease a lot after using scour, laundry powder, 84 disinfector and water to wash the fabric respectively.
6.Ear-loop type: 3-ply polypropylene cloth, low breathing resistance and high filtration efficiency.
7.The porous ceramics is composed of lots of bridge arch-shaped microspores that connected and well-distributed inside the material.When the fluid passes through these pores,the suspended matters,colloid particles and big molecular organic substances are withheld or absorbed to the inner surface of the pore,and result in filtration,purification adn even-dispersion,High strength,good resistance to abrasion,high temperature and corrosion,no pollution,long workinglife,and easy to regenerate,the porous ceramics are available for filtration and fluidization of variou gas and liquid.
8.The major factor causing resistance in membrane filtration is dissolving organic matter in raw water.
9.Oral nifcdipine ( 10mg, three times a day) decreased systemic vascilar resistance ( SVR ), mean arterial blood pressular (MBP) and renal vaselar rcsisiancc (RVR) , and increased cardiac output (CO), rcrai blood flow ( RBF) and glomcruler filtration raie(GFR)No sigai-ficent change was cbserved in the raio of SVR/RVR, RBF/CO and GFR/RBF.
10.Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.
