linhai 260 atv owners manualThe manual is a revised version of the earlier one, which was developed in 1977 and was widely used by field engineers engaged in sewerage and sewage treatment. However, a need was felt to revise and update the earlier manual taking into consideration the advancement in technology. It has also been realised that there is a need to look beyond coverage, to the quality of services in terms of making use of new advances in technology, use of low cost technology, use of recycled and more economical forms of user friendly technologies that can be expanded beyond cities to reach small and medium towns in the country. This is a technical guide book for the help of field engineers. Read More Specifications Imprint A Jba Publication Edition Type Reprint Have doubts regarding this product.

Performance of these wastewater treatment plants are essential parameter to be monitored as the treated effluent is discharged into River Ganga which is the National River of India. The performance evaluation will also help for the better understanding of design and operating difficulties in wastewater treatment plants. The performance evaluation was done on the basis of removal efficiency of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Coliform (TC) and Fecal Coliform (FC). The performance of prevailing oxidation pond and activated sludge process type was good in terms of BOD, COD and TSS removal. Even though the removal efficiency of total and fecal coliform was high (85-98), none of the plants meet the coliform discharge standards because of the high incoming TC and FC.

GIZ- IGEP has selected a team of an international consultant jointly with a national team of experts for better grounding of the work in the local system. ICLEI South Asia has been identified for supporting this process in the role of a national expert. The CPHEEO manual of 2000 will be updated to also include aspects of financial sustainability, public private partnerships, institutional strengthening and requisite policy interventions to appropriately address recent developments. STP should be designed in phases, refer clarification in table 1.1. First phase of STP should be for about 10 years but land of STP should be taken for 30 years period. However sewers should be designed to minimum waste water flow of 100 litres per capita per day. Industries, commercial buildings etc who often use water other than the municipal supply and may discharge their liquid waste into the sanitary sewers. Such quantities should be worked out separately. This is significant when water table is high and head of ground water is more than the head of sewage in sewers. Some quantity of sewage may leak out from defective joints and defective pipes when head of sewage is more in sewers than head of ground water outside. Infiltration and leakage mainly depends on quality of construction and water table levels. Infiltration can be considered, Para 3.2.7 Manual, 5000-50000 liters per day per hectare or 500-5000 liters per day per km length of sewers or 250-500 liters per day per manhole for sewers laid below ground water level. Thus the sewers are designed on the assumption that although silting might occur at minimum flow, it would be flushed out during peak flows. Erosion of sewers is caused by sand and other gritty material in the sewer and also by excessive velocity. Velocity in a sewer is recommended not to exceed 3 mps. Also from consideration of ventilation sewers should not be designed to run full. In case of circular sewers, table 3.6 of Manual(Hydraulic properties of Circular sections), the velocity is maximum at 0.8 full and is 1.14 times the velocity at full flow. The discharge at 0.8 full is 0.98 times the discharge at full flow. Therefore the maximum flow depth should be 0.8 full at ultimate peak flow for all pipe diameters. As such for present peak flows up to 30 lps, the recommended slopes for minimum velocity are given in Table 3.7 of Manual. These slopes would ensure minimum velocity of 0.6 mps in the early years. However now it is not common. Concrete pipes are commonly used now as these can be manufactured to any reasonable strength and laying is easy and jointing is leak proof. However these pipes are subject to corrosion where acid discharges are carried or where velocities are not sufficient to prevent septic conditions or where the soil is highly acidic or contains excessive sulphates. Only high alumina cement concrete should be used when it is exposed to corrosive sewage or industrial wastes. Salt Glazed Stoneware Pipes are mostly manufactured in sizes 80-1000 mm but sizes greater than 380 mm are generally not used due to economic considerations. The length of these pipes is 60 cm, 75 cm and 90 cm. These pipes are good for corrosion resistance and erosion resistance. However due to less length, more joints, difficulty in jointing, requirement of special bedding and less compressive strength of pipes manufactured in India; use of these pipes is reducing in India. AC pipes cannot stand high superimposed loads, subject to corrosion from acids in sewage and high sulphate soils, require special bedding and weak against erosion where high velocities are encountered; as such use of AC pipe is not prevalent. Cast iron, DI and steel pipes are not used due to high cost.Rates are also low. These days these pipes are used for making connection from house to sewer but not prevalent in street sewers. HDPE pipes are available up to 630 mm dia. The pipes are recently development in India but are costlier than RCC pipes and uPVC pipes. The welded joints are leak proof and as such some people have started using these pipes.GRP pipes are widely used in other countries where corrosion resistant pipes are required at reasonable rates. Characteristics of various pipes for gravity sewers makes comparison for different pipe options. 'Characteristics of metallic, PSC and GRP pipes' and 'Characteristics of plastic, DI and GI pipes' can be referred to adjudge suitability of pipe material option for particular use. Some states and ULBs have started adopting minimum diameter as 200 mm or even 250 mm. The logic is i) Maintenance of sewer system is generally not good and 150 mm dia sewer will block frequently and remain un attended for some time ii) Quality of construction in smaller size RCC main such as 150 mm is not good iii) The sewerage system is not totally closed one and undesired waste such as solid waste and drains finds way in sewerage, making smaller size sewer lines more prone to frequent blocking iv) The cost of pipe line element is only about 15 percent of total project cost and increase in pipe size from minimum of 150 mm to minimum of 200 mm size will increase cost of project by 2 percent whereas flow capacity increases by more than 80 percent.Generally sewers are laid in trenches by excavation in natural soil and then covered by refilling the trench to the original ground level. Four classes of beddings of A, B, C, and D are used for laying of sewers. Class A bedding may be either concrete cradle or concrete arch. Class B is bedding having a shaped bottom or compacted granular bedding with a carefully compacted backfill. Class C is an ordinary bedding having a shaped bottom or compacted granular bedding but with a lightly compacted backfill. Class D is one with flat bottom trench with no care being taken to secure compaction of backfill at the sides and immediately over the pipe and hence is not recommended. Class B or C bedding with compacted granular bedding is generally recommended. Shaped bottom is difficult and costly and hence not recommended. The pipe bedding material must be firm and not permit displacement of pipe. Sample Bedding Design The maximum depth of sewer pipe can be kept as per site conditions to minimize the number of pumping stations. Normally the same kept 8-10 m. Manholes are usually constructed directly over the line of the sewer. They are circular, rectangular or square in shape. Manholes should be of such size that will allow necessary cleaning and inspection. The circular manholes have been proposed on all sewer lines. Poly elastomeric M S flats footrest has been provided for entry into manholes.The sewer shall be in a straight line between two manholes. The minimum spacing of manholes varies from 30 m for smaller sewer dia to 300 m for sewers above 2000 mm dia. Circular manholes are stronger than rectangular and arch type manholes and thus these are preferred over rectangular as well as arch type manholes. A slab, generally of plain cement concrete at least 150 mm thick shall be provided at base to support the walls of the manhole and to prevent entry of ground water. The thickness of the base shall be suitably increased up to 300 mm, for manholes on large diameter sewers with adequate reinforcement provided to withstand excessive up lift pressures. For inspection, cleaning and testing of sewers, manholes shall be provided at every change of alignment, gradient, diameter, head of sewers and at junction of sewers. Type and size of man hole for different depths and different pipe dia. Rates of coverings More pumping hours give lower pipe size and hence cost saving. Future expected improvement in power supply may also be considered. It is generally provided to convey sewage from Sewage Pumping Stations to a higher level inlet chamber of nearby sewer or Sewage Treatment Plants. Characteristics of different pipes for pumping main help to choose between pipe options for particular site. It is designed according to the following considerations:Now wet well (no dry well) with submersible pumps are more prevalent. The construction is of RCC. Sulphate resistant cement is used in corrosive soils. Provision of flow measurement, adequate ventilation, safety equipments, pump lifting arrangements shall be made. All SPS will be provided with coarse screens before the wet well with clear opening of 40-50 mm between the bars for the manually cleaned type and 25 mm for the mechanical type. The screening units shall always be provided in duplicate. It is also provided with a bye bass on the upstream side, to avoid overflow of the screen channel in case of sudden power failure. Drainage facility shall also be provided in the individual screen channels to empty these channels for maintenance purposes. The capacity should not be too low to require frequent on-off of pumping sets. The capacity of the wet well is to be so kept that with any combination of inflow and pumping, the cycle of operation for each pump will not be less than 5 minutes and the maximum detention time in the wet well will not exceed 30 minutes of average flow. The high water level in sump well will not exceed invert level of lowest incoming pipe. Types of Sewage Pumps and Configuration Pumping units are designed to handle suitably peak, average and low-flow from connected sewers. The capacity of pumps shall be adequate to meet the peak rate of flow with 50 standby. The general practice is to provide 3 pumps for a small capacity pumping station comprising 1 pump of 1 DWF, 1 of 2 DWF and third of 3 DWF capacity. For large capacity pumping station, 5 pumps are usually provided, comprising 2 of. DWF, 2 of 1 DWF and 1 of 3 DWF capacity, including standby. The physical unit operations include screening, grit removal and sedimentation. The biological processes is broadly classified as i) suspended growth processes, both aerobic and anaerobic, including activated sludge process, extended aeration, lagooning, nitrification, de-nitrification and anaerobic digestion and ii) attached growth processes such as aerobic and anaerobic filter processes. The treatment plants are also called primary treatment if treatment is limited to physical process, secondary treatment when treatment is up to biological treatment and tertiary treatment when treatment goes beyond biological treatment to meet some further requirement of effluent quality. In case of decentralized more number of smaller capacity plants are constructed. Coarse screenings have opening of 75-100 mm for SPS and 50 mm for STPs. Medium screens have opening of 20-50 mm and fine screens have openings less than 20 mm. Coarse screens are manually cleaned but medium and fine screens are mechanically cleaned. Fine screens may be of the drum or disc or mat type.The major design parameters for secondary settling tanks designed to remove bio-flocculated solids are solid loading rate or solid flux as well as surface over flow rate. The overflow rates for settling tanks as per Manual. The smaller values in the range are applicable for plants less than 5 MLD. For STPs more than 10 MLD mechanical grit cleaning system should be provided. In case of manually cleaned grit chambers at least two units should be provided and all mechanically cleaned units should be provided with a manually cleaned unit to act as a bypass. The minimum size of grit to be removed is 0.2 mm although 0.15 mm is preferred where ash content is more. Detention period of 60 seconds can be taken.The settling velocities and surface over flow rates for ideal grit chamber at 10 degree centigrade. Longer detention period may affect the tank performance adversely due to setting in of septic conditions particularly in tropical climates.
