LAKASA Oil Interceptor LAKASA Oil Interceptor is required wherever lubricating oil, cutting oil, kerosene, gasoline, naptha, paraffin, trisod phosphate and numerous other light density and volatile liquids are present in the drainage. In commercial establishments such as service stations, garages, auto-repair shops, dry cleaners, laundries industrial plants or process industries having machine shops, metal treating process rooms, chemical process or mixing rooms, etc, there is always the problem of flammable or volatile liquids entering the drai nage system which can contaminate the sewer line and cause a serious fire or explosive condition. The discharge of oily wastewater, which consists of high degree of BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), FOG (Fat, oil and grease), and other organic wastes into natural waterways has disastrous impacts on aquatic life and the environments.

LAKASA Oil Interceptor is a preliminary treatment for oily (hydrocarbon) wastewater discharged from sources such as service & repair workshop, carwash bays etc. The effluent from the interceptor should be channeled to sewer line for further process and treatment.
LAKASA Oil Interceptor is designed to allow introduction of any liquid types for separation as long as there is sufficient specific gravity differential to permit gravitational separation. It is designed for intermittent and variable flows of water, oil or any combination of non-emulsified oil/water mixtures. LAKASA Oil Interceptor can be installed at drain lines in areas like parking garages, petrol stations, hangars, machine shops, and also industrial plants where oil, sediment and other volatile liquid are encountered. It prevents oil and sediment in wastewater from entering discharge lines and protect against water pollution. The design allows intercepted oil to be automatically drawn-off for storage in a continuous operation. Sediment should be removed from sediment bucket at regular intervals. To eliminate pressure build-up inside the interceptor, a vent connection on side of the body allows the venting of interceptor.
Coalescing Plate Separators - Taking advantage of the buoyancy of oil droplets in water, coalescing plates perform oil/water separation. The system consists of many corrugated plates stacked one above the other, forming a set of narrow channels through which the oily water must flow. As the water flows through the plates the oil droplets rise and meet the underside of the plates where they are captured and eventually as more droplets are captured a film forms which eventually forms larger drops. The large oil droplets rise to the surface of the separator through holes provided for that purpose as a layer to be removed manually or automatically. Coalescing plates offer high efficiency and low operating and maintenance costs because there are no moving parts and no replacement parts are needed or spent absorbents generated.
Environmental Quality Act, 1974 In the effort to meet the requirement of the Environment Quality Act, 1974, Standard B on the oil & grease of 10mg/l of effluent quality, the sizing of LAKASA Oil Interceptor is to be double the standard recommended size. This will ensure the effluent is double filtered and achieve good effluent quality.

Operation and Maintenance Guide The oil shall be skimmed and dirt, sand and sludge shall be removed on a quarterly basis at a minimum. Oil shall be handled as a hazardous waste stored and sent to a used oil recycler. If the oil is too thin to pump or skim, oil absorbent pads or pillows can be used to remove the oil. These can be sent for disposal or recycling, or if oil can be removed from them they can be reused (oil collected and sent for recycling). The first quarter‟s sludge/dirt shall be sent for waste characterization to determine if it can be disposed off as ordinary waste or hazardous waste. If hazardous, sludge shall be stored in labeled drums and picked up by a licensed hauler. If nonhazardous, sludge shall be disposed off to a landfill, and is not to be deposited on-site. 1.
2.
Manual draw off of oil. A routine inspection of oil interceptors should be undertaken at least once every 3 months by the inspection technician. Using a dipstick, the amount of accumulated oil and solids shall be measured to determine if a clean-out is required. Servicing and clean-out of oil to a separate storage tank pending for proper disposal whenever is necessary.
Normal Water Operating Line
Adjustable Draw-Off Sleeve 2mm Static Water Line
Automatic draw off of oil. During the first 2 weeks of operation, check the oil storage tank for oil build up to determine the frequency it needs to be emptied. If water is found entering the draw-off sleeve into the oil storage tank during normal working condition, adjust the draw off level upwards from 2 mm to 5 mm.

Sizing of interceptor meets the requirement. Water flow rates are within the specification. Adequate water retention time will ensure proper separation of oil/ water mixture. Perforated bucket at sludge chamber should be inspected and cleaned on a regular basis. The amount of debris such as sand, gravel, dirt, leaves, grass cuttings, etc., permitted to enter the system must be minimized. Automotive and truck engine crankcase oil should not be drained into the system. Sludge and deposits present in the oil will significantly reduce the effectiveness of the interceptor. Hydrocarbons entering the separator will be in a free non-emulsified state and capable of being separated from water by gravity separation. Detergent will emulsified the oil and allow it to enter the sanitary sewer system because detergents have a definite affinity for hydrocarbons. Wash water from truck washing racks must be routed directly to a sanitary sewer or treated with special equipment. It is advisable to install a flow rate controller at the upstream of the unit to ensure no accidental discharge of oil during periods of excessive wastewater flow.
Sizing of LAKASA Oil Interceptor In order to work properly the amount of wastewater flowing into the interceptor needs to be calculated. An estimate of the flow of water used in the washing process, and total volume generated each day shall be made. The maximum number of wash jobs per day should be used. Estimate peak wastewater flowrate and select the interceptor model with flow rating equal to peak flow rate or the next higher rate. Calculation by number of fixtures Peak flow rate Total nos. of hose outlet, equipments etc. that continuous discharging to drain line at a particular time Example A carwash bay, with total 3 water hoses are used for car washing during peak washing session. Each hose power is about 15 GPM (example). Thus the estimated peak water flow is 15 GPM x 3 = 45 GPM Calculation by area Calculation of flow rate Total area (length x width in meter) x collection of water (peak time) Example Length 30m, width 15m, collection of water : 75mm / 15 minutes Calculation = 30 x 15 x 75 ÷ 900 = 37.5 liter / second = 500 GPM

LAKASA Neutralization Tank LAKASA Neutralization Tank is also called Dilution Tank, designed to receive, dilute and neutralize corrosive and harmful chemical wastes before allowing such materials to be discharged into the public sewers or the environment, is suitable for centralized installation for neutralizing and dilution of laboratory acids and chemicals. Neutralization of corrosive, toxic and flammable wastes is necessary to the environment and piping systems, even when quantities and concentrations are small. Such wastes can cause physical damage to a building's piping or outside sewer systems and, if effluent is being discharged to the environment (such as rivers and lakes), severe damage can result to wildlife and water sources. Neutralization is the process whereby acids and alkalis are rendered harmless. The degree of neutralization can be measured by a system known as pH (positive Hydronium ions). The degree of measurement is a pH number of 7, which is neutral. Acids range from 0 to 6.99. Alkalis range from 7.01 to 14. The smaller the number, the higher the content of acidic waste. The higher the pH number, the higher the alkaline waste.
End-results of Neutralization Process The chemical reaction between Calcium Carbonate and acidic waste water will produce by-products of neutralized waste, carbon dioxide and neutral salts that can be safely discharged into municipal sewer Calcium Carbonate Neutralizing Agent

Retention Time
Capacity & Sizing LAKASA Neutralization Tank is designed for intermittent flow of acidic wastewater which attempts to achieve an average retention time of > 30 minutes, as such the interaction and dilution to be taken place between the acidic wastewater and the calcium carbonate based neutralizing agent. Proper functioning of the LAKASA Neutralizing System requires determining water flow or the volume of incoming acidic waste water, in order to achieve sufficient retention time for the neutralizing process to take place (see figure i). The initial rate of neutralization is rapid, however, as the pH of the acid waste rises, the rate of neutralization slows down. Neutralization reaction time of more than 45 minutes should achieve a safe pH level or a level which is considered high enough to be easily diluted with sanitary waste. Environmental Quality Act, 1974 According to the Environment Quality Act, the effluent with pH value of 5.5 to 9.0 is acceptable under its standard B requirement.

Maintenance The volume of limestones (Calcium Carbonate based neutralizing agents) and thus the neutralizing capacity of the system will be reduced gradually during the neutralizing process. There are various factors such as flow rate, concentration of acid waste, and temperature, determine the consumption rate of the Calcium Carbonate Neutralizing Agent. To ensure maximum performance, a full charge of the neutralizing agent should be maintained. Initially, inspection of the agent level should be made once a month. When the rate of consumption is determined. A maintenance schedule should be established to observe and maintain proper limestone levels in the tank. Limestone replacement should be performed at regular intervals. Typically, once every one to three months is sufficient. However, these intervals can be increased or decreased based upon application needs and performance. The limestone supplied are 1-3" in diameter and have a calcium carbonate content certified to be in excess of 90%. Solids in the waste stream can plug the tank and should be avoided.
Installation 1. 2. 3. 4. 5.
For underground installation, construct a solid manhole sump for housing the Neutralization Tank. Place at a firm & balance concrete base. Inlet & outlet is connected accordingly and properly. Neutralization Tank is to be filled up with full baskets of limestones (Calcium Carbonate based). Neutralization Tank is to be filled up with clean water until it reaches static water level. Water added to the tank helps facilitate dilution.

Conclusion : 1. Retention time of > 45 minutes will normally achieve optimum neutralization process. 2. LAKASA Neutralization Tank can increase pH of acidic water of initial pH~1.6 to pH~5.0 at the average of 0.12/minute and limestone requirement of 12kg/unit pH change. 3. The pH change is about 0.10 per kg limestone used. 4. The temperature of the water remains stable during the whole neutralization process. 5. The performance evaluation exercise on the LAKASA Neutralization Tank was limited in simulating the actual mode of application. There was no actual movement of liquid through the limestone during the study conducted by SIRIM. The efficiency of the neutralization tank is expected to increase with flow rate adjustment in an actual installation. 6. The volume of limestones (Calcium Carbonate based neutralizing agents) and thus the neutralizing capacity of the system will be reduced gradually during the neutralizing process. 7. A maintenance schedule should be established to observe and maintain proper limestone levels in the tank. Limestone replacement should be performed at regular intervals.
