evidence: Mixed liquor suspended solids -LRB- MLSS -RRB- is the concentration of suspended solids , in an aeration tank during the activated sludge process , which occurs during the treatment of waste water .. aeration. aeration. activated sludge process. Activated sludge#The process. waste water. Wastewater. The units MLSS is primarily measured in are milligram per litre -LRB- mg / L -RRB- , but for activated sludge its mostly measured in gram per liter -LSB- g / l -RSB- which is equal to kilogram per m3 -LSB- kg / m3 -RSB- .. Mixed liquor is a combination of raw or unsettled wastewater or pre-settled wastewater and activated sludge within an aeration tank .. aeration. aeration. MLSS consists mostly of microorganisms and non-biodegradable suspended matter .. MLSS is an important part of the activated sludge process to ensure that there is a sufficient quantity of active biomass available to consume the applied quantity of organic pollutant at any time .. activated sludge process. Activated sludge#The process. biomass. biomass. This is known as the food to microorganism ratio , more commonly notated as the F / M ratio .. By maintaining this ratio at the appropriate level the biomass will consume high percentages of the food .. biomass. biomass. This minimizes the loss of residual food in the treated effluent .. In simple terms , the more the biomass consumes the lower the biochemical oxygen demand -LRB- BOD -RRB- will be in the discharge .. biomass. biomass. BOD. Biochemical Oxygen Demand. It is important that MLSS removes COD and BOD in order to purify water for clean surface waters , and subsequently clean drinking water and hygiene .. BOD. Biochemical Oxygen Demand. Raw sewage enters in the water treatment process with a concentration of sometimes several hundred mg / L of BOD .. BOD. Biochemical Oxygen Demand. Upon being treated with MLSS and other methods of treatment , the concentration of BOD in water is lowered to less than 2 mg / L , which is considered to be clean , safe to discharge to surface waters or to reuse water .. BOD. Biochemical Oxygen Demand. The total weight of MLSS within an aeration tank can be calculated by multiplying the concentration of MLSS -LRB- kg / m3 -RRB- in the aeration tank by the tank volume -LRB- m3 -RRB- .. aeration. aeration
