Filtration speed

1. Filtration rate and filtration rate per unit of time through the unit filter area filtrate volume called filtration rate, namely: u = V / Atm3 / m2 where: A – filter area, m2;? T – filtration time, ? V – the volume of filtrate flowing out in time t, m3 the volume of filtrate obtained in unit time is called the filtration rate, which indicates the production capacity of filtration equipment. ? Filtration rate? Q = V / t = u.A? The unit m3 / h and L / min said.
In this case,
2. Factors that affect the filtration rate
In this case,
(1) the viscosity of the larger slurry filter, the greater the filtration resistance, the smaller the filtration rate;
In this case,
② cake thickness Thicker cake thickness, the greater the resistance, the smaller the filtration rate. When the thickness reaches a certain extent will filter termination;
In this case,
(3) The properties of the cake are incompressible. The particles of the filter cake are hard and the passage of the filtrate does not become smaller due to the increase of the pressure. The resistance basically remains unchanged or the increase of the resistance is very slow with the filtration time. Of the increase in proportion to increase; small particles in the larger pressure will block the role of the pore, so the initial pressure can not filter too much, to avoid premature blockage flow channel.
