  1. 1. ٢٠/٠٣/١٤٣٥ ١ Industrial Wastewater DischargeIndustrial Wastewater Discharge and Environmentand Environment Prepared and Presented by Dr. Helaley Abdel Hady Helaley Chief of Industrial Wastewater, Sludge and Reuse Sector Alexandria Sanitary Drainage Company. ١ International Summit: 19 – 20 January 2014 ٢ Analyzing the EnvironmentalAnalyzing the Environmental impact of industrial wastewaterimpact of industrial wastewater 1.

Impact on sewerage system Treatment plants Pump stations Pipelines Acids and alkaline discharge Oil, Grease & Detergents Sudden flow changes Sulphides Organic Solvents Organic solvents Dissolved bubble gases Scum Grit and suspended solids Scum Heavy Metals Hazardous organic matter High Temperatrure Detergents Organic and inorganic SS Impacts - Corrosion - Flow reduction . - Precipitation . - Clogging and flooding. - The difference in the speed of the flow of water inside pipes - The escalation of toxic hazardous gases to workers. - Reduce the life span of the network. impacts •Blockage in screens as a result of the accumulation of scum layers is difficult to remove, reduce screening efficiency . •Difficulty of sludge drying process. • •Impeding the processing of primary and secondary treatment operation which affects the re-use of treated . •Increasing organic load of the effluent impacts - The escalation of gases cause suffocation for the workers. - Corrosion of moving parts causing pump failure - Rise in pump temperature. - Corrosion in the pump column. 1.

  2. 2. ٢٠/٠٣/١٤٣٥ ٢ ٥ Main industrial pollution sources into Alexandria water bodies 2. Impact on Water Bodies ٦ Along the coast of Abu-Qir Bay, there exist about 22 different factories representing four major categories of industrial wastes which are: food processing and canning, paper industry, fertilizers industry and textile manufacturing. The wastes of these industries are of either organic or inorganic nature and are pumped to the sea through El-Tabia pumping station; it pumps out an average amount of 1.5–2.0 million m3 of polluted water per day 1. Abo Qir bay pollution sources ٧ West Zone of Abo Qir bay and the main industries disposing their effluents into it. Industrial Companies that discharges directly into Amia drain then to Abo Qir through Tabia pump station: - National paper company. - Kaha for preserved foods Co. - Agrokim for Agricultural Chemicals co. - Chemics for pesticides co. -Nasr for drying agricultural. Industrial Companies that discharges directly into Abo Qir Bay at Alexandria Governorate -Abo Qir for Fertilizers co. -Abo Qir power station. -60 Ton TSS. In addition to discharge of four big companies at Kafr El- Dawar with rate of 95000 m3/day Abo Qir bay pollution risk The pollution of Abu-Qir Bay region induced a panic oxidative stress in fish living in this area. This indicates that the industrial wastewater treatment in this area is not adequate to avoid the hazardous effects of such pollutants.
  3. 3. ٢٠/٠٣/١٤٣٥ ٣ ٩ Impacts of Marine Pollution 1. Create unpleasant sea shore conditions. 2. Affecting different touristic activities. 3. Affecting fishery activities. 1 - Water quality deterioration 2 - Reduction of surface area 3 - Reduction of lake production 4 - Lake depth flocculation 2. Lake Maryout problems ١١ *Total discharge on lake maryout 11,7 Mm3 Discharge quantities on lake maryout Fresh water 7 2,7 Mm3/day, 23% of total discharge. Agricultural drains, 8 Mm3/day, 68% of total discharge. Domestic drains, 900 thousand m3/day, 7.7% of total discharge. Industrial drains, 63 thousand m3/day, 0.54% of total discharge. ١٢ Direct discharge of industries into Maryout lakeDirect discharge of industries into Maryout lake There are 6 main companies discharges its industrial wastewater through lake Maryout. 1-Misr Amreya Spinning & Weaving (12,000 m3/d). 2-Petrochemical Company (25,000 m3/d). 3-El Amreya Petroleum Refinery Company (10,000 m3/d). 4-Salt and Soda Company (120 m3/day). 5-Sidi Krir Petrochemical Company (1000 m3/day). 6-Misr Petroleum Company (35 m3/day). The Total Direct Discharges = 48,155 m3/day

Petrochemicals Co. Sidi Krir for petrochemicals Co. Alex Fiber Co. Agricultural drains Roads Canal water Drains Indirect discharge Domestic sewage Direct discharge The major reason of the poor water quality in the Lake Maryout is the disposal of up to 900,000 m3/d of primary effluent of ETP and WTP discharges into lake Maryout and direct discharges from petroleum and chemicals industeries . ١٤ The dissolved oxygen concentration in the Lake drops to as low as 0.2 mg/L with high concentration of Nitrogen. This effluent has high organic load and low oxygen content. Activities to restore the Lake ecosystem Increase the dredging activity of the sediments in all basins in order to improve water circulation, self cleaning and fish production - Reeds harvesting, by the provision of additional machines to the fishery department. This activity could become financially self sustainable by the development of a paper making industry that would buy the reeds. - Provision of engineered wetland in strategic locations (Oumoum and Kalaa drains outfalls) in order to reduce the organic pollution and nutrient loads of water entering the Lake - Aerating the water at the outlet of the WTP and Kalaa drain in order to increase the BOD and decrease the H2S emissions --Increasing the water level and thus the storage capacity of certain basins. • El_ mex bay receives 10- 12 Mm3/day of the overflow of Maryout lake through El-mex pump station. ١٦ El Max bay pollution problems-3

They was dispose their raw wastewater directly into the sewerage system, which creates chronic street flooding problems all over the industrial zones. As well as affecting the quality of the old treatment plant influent located at the east of the city and accordingly will affect the newly instructed tertiary treatment plant. Borg El-Arab is a new industrial city within Alexandria containing around 1200 factory distributed within four industrial zones. The actual working is 700. Industrial activities includes: food, plastics, paper, weaving, building materials, chemical, pharmaceutical and various industries….etc. 3. Impact on Factories environment . • Microbial pollution and production operation threatening ٢٠ • Unpleasant odor emissions. • Flies problem. • Visual pollution. • Traffic problems
  6. 6. ٢٠/٠٣/١٤٣٥ ٦ ٢١ In and Out Infrastructure threatening stress on theUnder these circumstances we would like to to assureline Monitoring systems-Onimportance of applying effective control of industrial effluent quality to define on spot the violating industries and effective to enforcing industries to minimize their effluent pollutants . ٢٢ To minimize the amount of industrial discharges it must be encourage investment in the field of environment-friendly production technologies, applying sustainable industrial wastewater treatment options and encouraging using the most favored waste minimization options . Cease Industrial Pollution = Clean Environment ٢٤
