The rainfall rate is very low, but there is a huge quantity of ground water with good quality (average TDS around 1030 mg/l) and this leads the country to rely on this water source. The Great Man-Made River Authority (GMRA) was established to produce and transfer water from the ...
Item 1. A residue-removing solution for removing residues present on semiconductor substrates after dry etching and/or ashing, the solution comprising water and at least one component selected from the group consisting of (a) a keto acid, (b) a keto acid salt, and (c) an aldehyde acid sal...

A feasibility study was performed to remove COD and total nitrogen from sewage water influent in the upflow anaerobic sludge blanket column and the subsequent aerobic biofilter (UASB/BF). The hydraulic retention times of 12, 10, 8, and 5 h were employed to result in the organic loadings of ...
Tests on the use of the projection of ultra-cooled air for the removal of graffiti from railway vehicles have yielded significant results both for the degradation of the aerosols used in the graffiti and in the preservation of the vehicle’s support materials. The preservation of these materials...
A hexagonal four cell, two compartment water splitter having four Aquatech™ bipolar membranes alternating with four CMS cation membranes was used to treat scrubbing solutions having the compositions and percent total dissolved solids (%TDS) listed in Table 1, below: ...
By HomePlus Water on Aug 06, 2024 Question: Do you have graphene water filters for borehole water. My borehole water TDS is 19000. What would be the cost of such graphene filters. Thank you. Answer(s): Graphene water filter technology is still in its infancy and has not really been ...
7, the conventional CO2 recovery apparatus has a waste gas cooling device 1004 which cools waste gas 1002 containing CO2 discharged from the industrial facility such as a boiler and a gas turbine with cooling water 1003, a CO2 absorption tower 1006 in which the cooled waste gas 1002 containing...
Simultaneous removing of TDS was also showed well efficiency. However, TDS has never decreased to near zero as it was possible for the strong resins.Finally in the 4th phase of this research, natural samples from four water resources supplying potable water for the city of Qom have been ...
