WebSewage Effluent: 5-10: Sea Water: 8-12: Brackish Surface Water: 10-14: Brackish Well Water: 14-18: RO Permeate Water: 20-30: Mass Balance. A Mass Balance equation is used to help determine if your flow and quality instrumentation is reading properly or requires calibration. WebMixed liquor is a mixture of raw or settled wastewater and activated sludge contained in an aeration basin in the activated sludge process. MLSS are used to control the wastewater treatment plant in the suspended growth process. According to Lousada-Ferreira et al. (2010), MLSS are a critical operational parameter for aerobic MBR.
