Effluent based standards

แปลว่า(Environmental Engineering) Standards which set concentration or mass per time limits on the effluent being discharged to a receiving water.

stress concentration

แปลว่าความเข้มของหน่วยแรง (ตามบริเวณที่มีการเปลี่ยนหน้าตัดของโครงสร้าง)

Discrete settling

แปลว่า(Environmental Engineering) Settling in which individual particles settle independently, neither agglomerating or interfering with the settling of the other particles present. This occurs in waters with a low concentration of particles.

Maximum contaminant level (MCL)

แปลว่า(Environmental Engineering) The maximum allowable concentration of a given constituent in potable water.

Mixed liquor suspended solids (MLSS)

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

Mixed liquor volatile suspended solids (MLVSS)

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

time of concentration (Tc)

แปลว่าเวลาที่น้ำไหลจากจุดที่ไกลที่สุดของพื้นที่รับน้ำมาถึงจุดที่กำหนด

Hindered (Zone) settling

แปลว่า(Environmental Engineering) Settling in which particle concentrations are sufficient that particles interfere with the settling of other particles. Particles settle together as a body or structure with the water required to traverse the particle interstices.

Flocculant settling

แปลว่า(Environmental Engineering) Settling in which particle concentrations are sufficiently high that particle agglomeration occurs. This results in a reduction in the number of particles and an increase in average particle mass. As agglomeration occurs higher settling velocities result.

Compression settling

แปลว่า(Environmental Engineering) Settling which occurs in the lower reaches of clarifiers where particle concentrations are highest. Particles can settle only by compressing the mass of particles below.
