Deep Bed Filters. Deep bed filtration is fundamentally different from cake filtration both in principle and appHcation. The filter medium (Fig. 4) is a deep bed with pore size much greater than the particles it is meant to remove. No cake should form on the face of the medium. Particles penetrate into the medium where they separate due to gravity settling, diffusion, and inertial forces attachment to the medium is due to molecular and electrostatic forces. Sand is the most common medium and multimedia filters also use garnet and anthracite. The filtration process is cycHc, ie, when the bed is full of sohds and the pressure drop across the bed is excessive, the flow is intermpted and solids are backwashed from the bed, sometimes aided by air scouring or wash jets. 

Non-foaming scouring agent for jets and other equipment where foaming causes problems. By its chemical nature, PENTEX OS-NF is particularly well-suited for removal of oily substances, such as knitting oils, from knit goods and fabrics. 

BURCO SCOUR CS-LF offers a distinct advantage for continuous, semi-continuous and jet bleaching and preparation. 

Low odor, one-bath scour and dye carrier for jets, beams, and package dyeing. Use levels 1 to 2%. 

Very low foam surfactant and scouring agent for all textile fibers. Especially suitable for pressure and jet equipment. 

Multipurpose non-foaming lubricant for jet dyeing of polyester cotton blends. Also recommended as an after scour. 

Solvent scour low foaming for jet, beck, and continuous scouring of polyester and polyester blend fabrics. 

INTEX SOLVENT 244 is often used as an after-scour or after-clear for disperse dyed polyester fabrics. A mixture of the solvent at the rate of about 5% OWF may be added into the jet during the cool down at about 180F. 

Efficient scouring agent with low foam and de-aerating properties. Advantageous on beck, jet and package dye equipment—anionic.

In chemical process engineering, the most important instances of erosion are those where the fluid contains solid particles. If the fluid is a liquid, this type of wear is called hydroabrasive wear or scouring wear, and with gaseous fluids, it is called jet wear. In both types of wear, plowing is active as the essential mechanism, and with steeper angles of impact, there is an additional component causing destruction of the material. Chemical reactions can also occur. 

Figure 11 presents the rms fluctuating-flow profiles of the wall jet. The stream-wise velocity fluctuations (Fig. 11a) peak at about 0.30 near the wall 0.1) and near the centerline of the free shear layer r j = 1), but there were not enough computational cycles to achieve complete convergence of these second moments. The transverse velocity fluctuations (Fig. 11b) peak near rjj = 0.6 and are nonzero at the bottom of the boundary layer ( rjj = 0) because of turbulent fluctuations from the fluidized bed. The Reynolds stress (Fig. 11c) peaks near the wall. The density fluctuations (Fig. lid) are largest near the wall because of turbulent scouring of dust from the fluidized bed. Pressure fluctuations (Fig. lie) range from 10 to 30% because the wall jet flow is supersonic.
