Definitions

  • the present invention relates to providing a more sensitive and sustainable management of the leachate waters compared to the conventional pressure-driven membrane systems, thanks to the advanced treatment of the leachate waters received from domestic/industrial solid waste sanitary landfills, with the innovative membrane systems based on membrane distillation technology, which focuses on an operation where (i)-more preferable technical performance levels are achieved thanks to having higher quality in discharge waters and lower volumes in membrane concentrates and where (3 ⁇ 4 ) -lower unit treatment costs are achieved thanks to the cost-free coverage of the MD heating requirements by making use of the low pumping energy consumption of the MD and the heat obtained by burning the landfill gases in the landfill cogeneration unit, together with producing less discharge water due to reduced in-house concentrated waste loads; and additionally where (in)- the MD concentrate is utilized by making use of its inert heat by incinerating said concentrates and disposal thereof outside the landfill; and which benefits from eco-innovative in-house concentrated waste management practices based on a versatile return/distribution where membrane concentrates are not just returned to the landfill and where said concentrates
  • sanitary landfills are still the most economical solution for the disposal of domestic and industrial solid wastes.
  • sanitary landfilling generates solid waste leachate waters, which are hard and expensive to treat.
  • Leachate water can be defined as the extracted portion of the dissolved and suspended materials leaching from the solid waste. These waters stem from the liquids generated by the degradation of wastes through surface drainage and the flows from rain waters and ground waters going inside the sanitary landfill.
  • Leachate waters usually have a dark color, odor and they contain high levels of organic and inorganic contamination loads. It is characteristic of the leachate water that it contains contaminations in 4 different groups: Organic compounds (aromatic hydrocarbons, phenols, pesticides, etc.) stemming from dissolved organic materials (such as volatile fatty acids and humic materials) and chemical residues in low concentrations; inorganic contaminants (Ca , Mg , Na , K , L , Fe , Mn , CI " , S0 4 2" , HCO 3 ); heavy metals (Cd +2 , Cr +3 , Cu +2 , Pb +2 , Ni +2 , Zn +2 ); and microorganisms (coliforms).
  • Organic compounds aromatic hydrocarbons, phenols, pesticides, etc.
  • inorganic contaminants Ca , Mg , Na , K , L , Fe , Mn , CI " , S0 4 2" , HCO
  • leachate water Treatment of leachate water is usually considered according to the landfill duration or BOD 5 /COD ratio. If this ratio is 1, leachate water is defined as new; it said ratio is lower than 0.1, it is defined as old leachate water.
  • Direct return operation is not preferred in winter months due to increased amounts of leachate water related to the increased precipitation. For this reason, the winter operation in facilities working with returns in Turkey is discharge to the sewage system. Furthermore, at the first stage of transitioning to energy generation by landfill gas, especially in the first 1-2 years of operation in the facility, return of leachate water to landfill area cannot be performed. In this period, as it can be necessary to discharge the leachate water over the collection chimneys, it is possible to encounter situations where, in contrast to return to the landfill area, leachate water is discharged outside the area more often.
  • the treatment of leachate waters is performed via treatment facilities with "conventionale advanced treatment with multi-step sequential technological practices.
  • the appropriate process(es) are selected among adsorption, pressure-driven membrane processes (conventional membrane technologies) and ozonization, advanced oxidation such as UV, H 2 0 2 , Fenton, photo-Fenton, electro-oxidation. Simultaneous use of sequential treatment systems in multiple steps increases operation risks as well as causing high leachate water disposal costs.
  • anaerobic treatment has the advantages of allowing the degradation of organic materials in leachate waters in the absence of oxygen and less generation of biological residual sludge, less energy consumption, biogas generation, less phosphor dosage requirement for the development of anaerobic bacteria, high levels of organic material removal; said technology has the main disadvantages such as the heavy metals preventing the biological degradation of organic contaminants, ammonia toxicity and over-dependence of the process to the changes in the temperature and pH of the leachate water.
  • MF and UF processes are the most basic membrane processes utilized in industrial practices.
  • the operational pressures in said processes are between 0.5-5 and 1-10 bar, respectively.
  • contaminant separation sizes it is possible to remove solid particles, microorganisms and partially colloidal materials with MF process; and solid and colloidal materials, organic materials with large molecular sizes (5000 Da and above) with UF process from the water and waste water environments.
  • MF process is utilized for the separation of liquid-solid mixtures
  • UF process is used for the separation of liquid-solid and organic-inorganic mixtures.
  • Another reason for preferring both processes in various industrial practices is to reduce the unit treatment costs by increasing the performance of the NF and/or RO processes located thereafter, depending on the contents of the waste water to be treated.
  • NF process is between UF and RO processes in terms of operation pressure (5-30 bar) and contaminant removal size; it is used for the removal of multivalent dissolved inorganics and organic materials with medium to large sizes (1000 Da and above) from water and waste water environments.
  • RO process is a membrane process which forms the last step of the pressure driven membrane processes and which has the lowest molecular separation size.
  • organic materials with very low (100-1000 Da) molecular weight and monovalent inorganics can be treated with effective separation performance (respectively >80% and >99% for organic and inorganic).
  • This methods is used commonly in practice for obtaining high quality, clean water from domestic and industrial waste waters for water recovery and industrial use, notably for obtaining drinking water from sea water.
  • Membrane concentrates are waters/waste waters which occur as a result of the passing the target water/waste water through the membrane, which are, most of the time, not re-usable due to their more intensive contents and which require more treatment or disposal.
  • the challenges faced in the management and disposal processes of concentrated wastes are the most essential techno-economic limiting factors in the effective use and proliferation of integrated membrane process practices on the field.
  • (i) -sanitary landfilling, (ii) -burning via incineration or (Hi) -discharge to a central waste water treatment plant' are the main practices for the disposal methods of membrane process concentrates in Turkey.
  • the disposal methods are generally utilized in the disposal of concentrates with low/very low volume due to the technical and economic limitations encountered in practice.
  • inertly disposable final wastes can be obtained from concentrated flows and thus, it is prevented to have liquid wastes to be discharged into the receiving environment ⁇ zero liquid discharge).
  • the equivalent fuel calorific value of the concentrate to be disposed is expected to be at least at the level of the low quality lignite with 2500-3500 kcal/kg, which is mined in Turkey.
  • Concentrate flows arising from the advanced treatment of leachate waters with pressure driven conventional membrane systems are usually disposed of by returning said wastes to the solid waste landfills. Not only the contaminant concentrations but also the high volumetric amounts in such flows transferred to the landfill area under constant operation, increase the contamination load of the raw leachate water going to conventional treatment at the first stage over time. This strains the efficient operational capacity of the conventional system.
  • MD Membrane distillation
  • MD is a membrane process which develops various wastewater treatment practices and which is preferred more and more in the practice, due to (i)-its operability in flexible environmental conditions, (3 ⁇ 4 ) -it's very high efficiency in the removal of dissolved organic and inorganic contaminants and (iii)-bemg able to allow operation at lower costs compared to pressure driven conventional membrane processes when the thermal energy required for heating is provided at low costs.
  • MD is a membrane process whose driving force is temperature, which utilizes micro-porous membrane and which allows high-quality treated water to be obtained with high leaching performance (generally excluding volatile organics, >99% for dissolved organics and inorganics (up to 97% for ammonia)) on waste waters.
  • the process can perform separation at >99% efficiency even in waters with very high osmotic pressure, such as RO concentrates and waters with high salinity, it can be operated at much higher water treatment rates (90%-%97) compared to pressure driven membrane processes and it allows for obtaining concentrated waste flows with much less volumetric amounts (3%-% 10).
  • the water flow which is in the feed flow at a certain temperature difference between feed and outlet water, is prevented from going through the membrane pores without applying additional pressure and water is allowed to pass through the membrane in the steam phase.
  • the water steam passing through the membrane is condensed by cold flow and treated water is generated.
  • nonvolatile components are prevented from going to the water steam phase and a filtrate flow with very high purity is obtained compared to conventional distillation.
  • the Chinese patent document numbered CN101928094 provides a technology for the treatment of leachate waters coming out of domestic/industrial solid waste sanitary landfills.
  • Said technology comprises the steps of converting garbage waters into nitrate, performing the membrane operation with ultrafiltration membrane, utilizing nanofiltration membrane and reverse osmosis membrane, performing electro-osmotic treatment to treated water and finally performing distillation.
  • a membrane process practice for the treatment of leachate waters comprises the steps of separating the calcium ions from garbage waters, increasing surface tension to preferably lb mN/m and performing membrane distillation afterwards.
  • the main objective of the present invention is to provide a more techno-economically preferable, more sensitive and sustainable management of the leachate waters coming out of the domestic/industrial solid waste sanitary landfills, compared to the waste water treatment systems formed by conventional advanced treatment systems; thanks to the innovative membrane systems based on MD technology; with a focus on obtaining discharge water with higher quality and lower membrane concentrate volumes and performing treatment at lower costs while considering various concentrate disposal options.
