Wastewater Characterization 6. Wastewater Treatment 7. Solid Waste Problem 8. Conclusion. Profile of the Sugar Industry: Sugar is one of the significant agricultural products and industries processing . Beet Sugar Factory. De Smet Engineers & Contractors’ expertise in beet sugar starts at the beets reception yard, including feedstock analysis, storage, handling, washing and slicing before Sugar extraction of the juice by pays particular attention to agronomic specificities, climatic and local environmental aspects so as to optimize the installation . If recovered waste water from an aeration pond is to be ren­ dered suitable for discharge to the aquatic environment or for recycle and reuse in a beet sugar factory, it should be subjected to filtration or separation to remove clay tur­ bidity and bacterial and algae cells. The removal of these.

The sugar industry uses flume water circuits for the washing of sugar beet. Flume water contains high amounts of suspended solids (soil particles) as well as organic material (from the beet). In many factories, lime milk is added to the flume water to keep the pH value between 10 and 11 (so-called alkaline operation). The principles of anaerobic processes for the treatment of beet sugar factory effluents are outlined. Sixteen such plants are operating at factories in the German Federal Republic, most of them using the contact process; two plants of this type are shown in diagrams. Data on COD degradation at Plattling and Offstein factories are graphed and discussed.   Urea and ammonium phosphate were used as nitrogen and phosphorous supplements. Average composition of 1 g beet sugar molasses in 1 L water was: TKN , Fe 2+ , Ni 2+ , Zn 2+ , Mn 2+ and S 2− mg/L, COD and BOD 5 were and mg/L, respectively. Analytical procedures. The size of the annual sugar beet crop is approximately 2,, tons, of which 75% is water. This means that 1,, gallons of water must be managed each day. Most of the water comes from the evaporation process as condensed steam from the evaporators.

  Sugar was first introduced by India during the fourth and sixth centuries by cutting sugarcane [].Sugar can be produced from sugarcane and sugar beet, Out of nations nearly 65 nation produced from sugarcane, nearly 40 are from sugar beet and 10 are from both [].The top ten nations, which produced two-thirds of total sugar worldwide is tabulating in Table 1 []. A water and waste water system equipped with a biological waste water treatment plant is considered. Its characteristics are assumed to match the data taken from a real Polish sugar factory. Water Characteristics of the Ely Factory (Great Britain) Name of company British Sugar Corporation Ltd. Typical dates of campaign September 21 to February 1 Annual beet tonnage processed , Average hour tonnage processed 4, Source of fresh water River Ouse Treatment of fresh water None Type of diffuser 1 RT with return of pulp press. It also coagulated turbidity from the waste water and removed the colour present in the waste water. Treatment in lagoons It is widely practiced in sugar industry. Aerobic lagoons is possible only if the organic load is limited to 60kg/ha/day. Aerobic pond system can produce a .
