Drainage volume

Any liquid, gaseous or aerosolic waste discharged in the environment. Generally, it is a complex mixture. For example, wastewaters include mine water effluent, mill process effluent, tailings impoundment area effluent, treatment pond or treatment facility effluent, seepage and surface drainage. Volume 1(9,10,14), Volume 2(2,5). 

Estuarine water Coastal body of ocean water that is measurably diluted with fresh water derived from land drainage. Volume 1(2). 

Subsequently, the whipped sample was allowed to stand at 25 °C for another 30 min and then the drainage volume was measured. With this volume the foam stability was represented by the ratio of drainage volume/initial volume (20 mL). 

Vd = drainage volume = volume of carrier-reservoir rock through which... 

A striking feature, in Fig. 6, is the similarity of the concentration values in the different types of water for increasing drainage volumes, except for SiO2 and Na of spring waters, which vary from 8 ppm in southern Ivory Coast to 35 ppm in the pre-Sahelian area.

(a) Drainage volume Fsr in dependence on the amount of PDADMAC the dotted lines exhibit the point of zero charge in the suspension, (b) Net charge of the residual solution/mixture in dependence on the amount of added PDADMAC...

A common form of turbine pump is the vertical pump, which has the pump element mounted at the bottom of a column that serves as the discharge pipe (see Fig. 10-46). Such units are immersed in the liquid to be pumped and are commonly used for wells, condenser circulating water, large-volume drainage, etc. Another form of the pump has a shell surrounding the pumping element which is connected to the intake pipe. In this form, the pump is used on condensate service in power plants and for process work in oil refineries. 

Volume 1 of National Fire Codes (National Fire Protection Association, Quincy, Massachusetts) contains recommendations (Code 30) for venting, drainage, and dike construction of tanks for flammable liquids. 

Simple, but gives relatively inefficient separation. Used for primary dewatering where the separations involve large feed volumes, and underflow drainage is not critical. 

Uniformity of the rate of feed will be ensured by a constant-weight feeder density control may be automatically obtained through a measuring probe on the media-return line that adjusts delivery of the nec-essai y volume of media from the densifier or media thickener the viscosity can be controlled automatically by continuously testing a predetermined volume of return media and adjusting the divider under the drainage screen for media cleaning as needed pH control can be automated by conventional methods. 

This section provides a general overview of the properties of lake systems and presents tlie basic tools needed for modeling of lake water quality. The priiiciptil physical features of a lake are length, depth (i.e., water level), area (both of the water surface and of tire drainage area), and volume. The relationship betw een the flow of a lake or reserv oir and the volume is also an important characteristic. The ratio of the volume to the (volumetric) flow represents tlie hydraulic retention time (i.e., the time it would take to empty out the lake or reservoir if all inputs of water to the lake ceased). This retention time is given by the ratio of the water body volume and tire volumetric flow rate. 

If complete system drainage and pump-out is to be made into this vessel, then the volume capacity of all of the piping and equipment must be taken into account. 

For Class B, these values are approximately doubled. In addition to the volume requirements, limits are also imposed on the length of the graduated part of the burette and on the drainage time.
