Waste drain

Sample collection varies from hand sampling procedures at a single point to more sophisticated multipoint sampling techniques, such as the equal discharge increment (EDI) method or equal transit rate (ETR) method. Different types of water samplers can be used to collect water samples from bodies such as rivers, seas, lakes, etc. The Blumer sampler [30], Deutsche Hydrographisches Institute sampler (DHI) [31], and a high volume water sampler, designed to pump water from a defined depth below the water body surface outside the wake of the survey vessel, are suitable as samplers [32], The Kemmerer and van Dorn samplers may also be used for water sample collection. For rivers, up- and downstream samples are usually required, as well as the points where tributaries or waste drains join the main stream under study. 

Specialized collection and treatment systems are designed and operated based on the specific properties of the CMP waste drained from the clean room. Therefore, it is paramount to understand the details of the CMP waste, such as, but not limited to, the following ... 

Another key aspect to treating CMP waste streams is to ensure that only the wastes assigned to the waste treatment system are sent down the drain. In short, a specific waste drain is not to be used as the general-purpose drain. A drain must be assigned for the collection of a specific CMP waste since the treatment system is designed around the composition of the waste.

On September 10, 1985, a leak of radiologically contaminated water occurred at four locations near the N-29 craft shop along the decontamination waste drain line between the N Reactor building and 116-N-2 facility (UN-lOO-N-6). Approximately 6,800 L (1,800 gal) of irradiated water was released. The water contained a total estimated 0.2 Ci of Co, 0.04 Ci of...

The radioactive waste drain system collects radioactive liquid wastes from equipment and floor drainage of the radioactive portions of the auxiliary building, aimex building, and radwaste building and directs these wastes to a centrally located sump located in the auxiliary building. The contents of the siunp are piunped to the liquid radwaste system tanks.
