Municipal Landfill Leachate Wastewater Treatment Equipment Landfill leachate is the result of water percolating through waste deposits, that have undergone aerobic and anaerobic microbial decomposition. In recent years, increasingly stringent wastewater discharge requirements, which have raised questions regarding the efficacy of co-treatment of leachate in municipal wastewater treatment plants (WWTPs）.     Leachate generation is a major problem for municipal solid waste (MSW) landfills and causes significant threat to surface water and groundwater.  Leachate can be defined as a liquid that passes through eland fill, and has extracted dissolved and suspended matter from it.  Technologies for landfill leachate treatment include biological treatment, physical/chemical treatment and “emerging” technologies such as reverse osmosis (RO) and evaporation. … Physical-chemical treatment methods include oxidation, coagulation /flocculation, activated carbon, stripping, evaporation, filtration and RO. Hinada has a professional team in wastewater of Landfill leachate, we also provide the truly integrated solution to water and wastewater project, from designation, supplying, installation support and commissioning to training.

Anaerobic Biological Treatment such as anaerobic lagoons, reactors. Physiochemical treatement such as air stripping, pH adjustment, chemical precipitation, oxidation, and reduction. These leachates must be appropriately treated before being discharged into the environment. Generally, the leachate characteristics such as COD, BOD/COD ratio, and landfill age are necessary determinants for selection of suitable treatment technologies. Rapid, sensitive and cost-effective bioassays are required to evaluate the toxicity of leachate before and after the treatment. This review summarizes extensive studies on leachate treatment methods and leachate toxicity assessment. It is found that individual biological or physical-chemical treatment is unable to meet strict effluent guidelines, whereas a combination of biological and physical-chemical treatments can achieve satisfactory removal efficiencies of both COD and ammonia nitrogen

High purity automotive urea solution, for vehicles with colorless, transparent and clear liquid. Automotive urea is a special exhaust gas purifying and reducing agent for diesel engine The scientific name of automobile urea (automotive urea, automobile environmental urea) is the diesel exhaust treatment solution. Used in diesel engines. It is a consumable that must be used in SCR technology to reduce the pollution of nitrogen oxides in diesel vehicle exhaust. Automotive urea is additives for diesel engines. The urea solution is injected into the catalyst of the SCR system triggering a chemical reaction that converts highly toxic nitrogen oxides (NOx) into nitrogen (N2) and water vapour (H2O), gases that are harmless to the environment. What exactly is urea? Not to be confused with urine (seriously, some people do), urea is a solution of 32.5% urea and 67.5% in de-ionized water. It's injected directly into the vehicle catalysts using an injector no bigger than a lead point in order to combine with NOx. The resulting mixture creates harmless inert nitrogen and water. Without the urea, a catalyst cannot function. Urea has been around for some time within the trucking industry, but in that environment, it is comprised of a completely different concentration. Urea technology production process as below: Urea Particle grain-----Dissolved in high purity water( 2 stages of RO System + EDI Technologies) -----100 mesh Bag filter-----5u cartridge filter----1u cartridge filter-----0.01u Ultrafiltration System. Hinada has special developed one type of UF Membrane for vehicle urea production, any further information please contact with us. The importance of automotive urea in Diesel engines:  Diesel engines offer higher power, thanks to their high compression. Trucks travel a lot of kilometers and the price of diesel is lower. Diesel engine components are more robust and therefore last longer. Having more torque-force applied to make something turn-makes them ideal for moving heavy loads. With no ignition system, diesel engines can work in adverse weather conditions and with high humidity.

Please protect the tank no pollution and correct connection. Please check the input pressure regularly, if the pressure is too low to filtrate, then try to increase some pressure, once the input pressure stills no increase, it’s probably blocked need to clean. During production, normally, the pressure is about 0.2 MPa or less, the maximum pressure can't more than 0.25 MPa, otherwise it will damage the filter breakdown, tank or even accidents Cleaning process, almost very week try to clean one time, just turn on the valve to “ back wash” about 2 minutes, then turn to “fast filter” outlet the clean water, repeat 1 times , then turn to “filter” location is ok. When the equipment planning to stop working for a while, please clean the FRP vessel and make sure clean. Working temperature: 20 to 45 ℃   Reverse Osmosis System input water quality demanded it removes up to 98% of chlorine, chemicals, heavy metals, sediment, and other contaminants that other systems fail to remove while adding good minerals to produce clean, pure mineral water with a neutral pH (pH 6.8 - 7.2) and restores 15-30 ppm natural calcium and magnesium minerals removed during the reverse osmosis process to produce clean, pure pH Balanced Mineral Water on Tap.

Agricultural Water Treatment Application: 1.Agruiculture purpose 2.Breed Farm like sharmp or fish 3.City tap water Agriculture is by far the largest water use at global level. Irrigation of agricultural lands accounted for 70% of the water used worldwide. In several developing countries, irrigation represents up to 95% of all water uses, and plays a major role in food production and food security. Future agricultural development strategies of most of these countries depend on the possibility to maintain, improve and expand irrigated agriculture. On the other hand, the increasing pressure on water resources by agriculture faces competition from other water use sectors and represents a threat to the environment. Water is a resource that may create tensions among countries down and upstream. Irrigated agriculture is driving much of the competition since it accounts for 70-90% of water use in may of these regions.Source: Turkmenistan and Uzbekistan figures from David R. Smith “Climate Change, Water Supply, and Conflict in the Aral Sea Basin”, paper presented at the “Pri-Aral Workshop 1994”, San Diego State University, March 1994: Others from Peter H. Gleick, Water in Crisis (NY, Oxford University Press, 1993). Within the European Union (EU) agriculture represents around 30% of total water abstraction. The intensity of irrigation in different countries obviously varies depending on the climate, the crops cultivated and the farming methods. For example, the role of irrigation is completely different in Southern European countries, where irrigation is essential for agricultural production, compared to Central and Western Europe. In fact the major part of irrigated land in Europe is located in the South with Spain, Italy, France, Greece and Portugal accounting for 85% of the total irrigated area in the EU. For example, in Spain irrigated agriculture accounts for 56% of total agricultural production, occupying only 18% of the total agricultural surface. Water Resources For Irrigation: Water used for agriculture comes from natural or other alternative sources. Natural sources includes rainwater and surface water (lakes and rivers). These resources must be used in a sustainable way. Rain water resources rely on the atmospheric conditions of the area. Surface water is a limited resource and normally requires the construction of dams and reservoirs with a significant environmental impact. Alternative sources of irrigation water are the reuse of municipal wastewater and drainage water. However the use of recycled water for irrigation may have some adverse impacts on the public health and the environment. This will depend on the recycled water application, soil characteristics, climate conditions and agronomic practice. Therefore it is important that all these factors are taken into account in the management of recycled water. Lets study this a little bit further. Reuse Of Water For Irrigation: Water reuse for irrigation is a normal practice worldwide. In Europe, for example there is a large project in Clermont-Ferrand, France since 1997 where more than 10.000m3/day of tertiary treated urban wastewater are reused for irrigation of 700Ha of maize. In Italy more than 4000 Ha of various crops are irrigated with recycled water. Spain also counts with several similar projects. The water quality used for irrigation is essential for the yield and quantity of crops, maintenance of soil productivity, and protection of the environment. For example, the physical and mechanical properties of the soil, ex. soil structure (stability of aggregates) and permeability, are very sensitive to the type of exchangeable ions present in irrigation.
