Nitrification

แปลว่า(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.

Automated estimation tools

แปลว่า(Software Engineering) tools that help in estimating project cost or effort

Bed-In

แปลว่า(english) Method whereby drag may be rammed in the pit or flask without necessity of rolling over. Process used in production of heavy castings.

Mixed liquor volatile suspended solids (MLVSS)

แปลว่า(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.

Jacking Equipment

แปลว่า(Concrete Engineering) In prestress concrete, the device used to stress the tendons.

Mixed liquor suspended solids (MLSS)

แปลว่า(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.

Total dissolved solids

แปลว่า(Environmental Engineering) (TDS) is the amount of dissolved matter in the water.

Blowhole

แปลว่า(english) A defect in a casting caused by trapped steam or gas.

Vector:

Blue Annealing

แปลว่า(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

Aging 2

แปลว่า(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.

Payment for Plant and Materials in Event of Suspension

แปลว่าการชำระเงินค่าอุปกรณ์และวัสดุในกรณีการสั่งหยุดงานชั่วคราว
