Action leakage rate

The standards for LDS also specify a minimum bottom slope of 2% and require the installation of a leak detection sump of appropriate size to allow the daily monitoring of liquid levels or inflow rates in the LDS. Specifically, the sump should be designed to detect a top liner leakage rate in the range of action leakage rate (ALR) specified in the leak detection rule. 

Droplets of the stripping phase generally range from 80 to 800 pm in diameter, that is, they are larger than the 0.03 pm wide pore in the hydrophobic support. Therefore the leakage of the stripping phase into the feed is prevented. Both phases are continuously circulated via the action of independent peristaltic pumps. There is a constant supply of the LM components, and therefore desorption/release of the membrane phase of the SLM from the hydrophobic support pores is lowered. At the same time, concentration gradients of the metal are maintained on the feed side, and so the rates of mass transfer are maximized. 

It may also be defined as the destruction of metal by electrochemical action, and it cannot take place unless an electrolyte is present. These leakages are cansed primarily by corrosion as the result of the exposure of the inner surface of the pipeline to water. However, corrosion of the external surfaces of pipelines also occurs because the exposure to their external environment may influence the corrosion rate of pipelines [2]. 

Thus we see that in order to ensure maximum adhesion of Class I dust (i.e., nonaggregating dust) and prolonged action of the charged substrate, the contact potential difference between the surface of the particles must be maximized, and the rate of charge leakage upon contact must be minimized.
