Edetic acid | C10H16N2O8 - PubChem

Edetic Acid is the acid form of edetate, a chelating agent with anti-hypercalcemic and anticoagulant properties. Edetic acid binds calcium and heavy metal ions, forming soluble stable complexes which are readily excreted by the kidneys. This results in a decrease in serum calcium levels. This agent is also used as an anticoagulant for blood specimens and is applied as a treatment of lead ...

Water Treatment Plant - an overview | ScienceDirect Topics

The wastewater treatment plant is designed to treat 250 gpm (56.8 m 3 h −1) of which 66% is recovered by the membrane processes and the rest through the brine evaporator/crystalliser unit (Fig. 5.6).The wastewater flow is generated by make-up RO reject (64%) (from make-up water plant), power block blowdown (22%) and mixed bed regenerate waste (14%).

What Are the Properties of Demineralized Water and How Can ...

Mar 26, 2018· When steam is produced inside the boiler, the water particles collect and condense, then are recycled and used as part of the boiler feed water. Technically, the condensate that the steam-making process produces is distilled, but dissolved gases such as oxygen and carbon dioxide are sometimes present.

Lead chromate | PbCrO4 - PubChem

Prismatic PbCrO4 particles break up in the lung and sustain a high concentration of isometric particles of lead chromate and another lead-containing compound in the BAL. The CrO3 instilled particles react with endogenous compounds or are transformed to insoluble hydroxyl complexes instead of diffusing very rapidly through the alveolar-capillary ...

Filtration - Wikipedia

Filtration is a physical or chemical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass. [citation needed] Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate.Oversize particles may form a filter cake on ...

Boiler blowdown - Wikipedia

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of ...

Ventilation (architecture) - Wikipedia

Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives.

Clarifier - Wikipedia

Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the ...

Biofilter - an overview | ScienceDirect Topics

A fully functioning biological filter, or biofilter, should be capable of removing a large majority of toxic nitrogenous wastes produced within a closed system.The biofilter is populated by two distinct physiological groups of nitrifying bacteria: those that oxidize ammonia to nitrite and others that oxidize nitrite to nitrate (Fig. 20.6) (Bock and Wagner, 2006; Könneke et al., 2005).
