MBR LEACHATE TREATMENT

Key Message

Landfill leachate is known to be one of the most complex wastewaters, and its treatment demands the most robust, adaptable and reliable technology that is in fact the external MBR with tubular UF membranes. Given the high fouling potential and the low filterability in leachate MBRs, the vast majority of MBRs for landfill leachate treatment are based on the external tubular membrane technology.

Benefits of MBR Treatment of leachate with tubular UF​

Biological processes are the core of the treatment process in most cases. In this way, organic matter and nitrogen are eliminated and released as CO2 and N2 gases. The Berghof external MBR entails numerous advantages over the conventional biological treatments and the submerged MBRs, as enumerated below:

Efficient

Highly efficient biological treatment: the operation at high MLSS concentration (12 – 15 g/L, up to 30 g/L) provides long sludge ages, which intensifies the acclimatization of biomass and its performance even with the most complex leachates. Slowly biodegradable organics and nitrogen are removed very efficiently.

Plug & Play

Quick and flexible implementation. Filtration systems based on Berghof membranes are 100% modular and plug & play. In addition the systems can be easily containerized. Retrofitting and upgrading of conventional leachate treatment plants is simple and fast. Future expansion of the plant can be done very easily.

Minimum footprint

Application of a conventional activated sludge (CAS) technology in dairy industry is known to present poor sludge settleability. This can hamper the fulfillment of tight discharge limits. <br><br>Our external tubular MBR technology presents COD removals even higher than 99%, producing a clear effluent, free of solids and FOG and COD &lt; 50 mg/L.

Effluent Quality

After treatment with tubular ultrafiltration membranes the leachate effluent is free of solids, without turbidity (&lt;1 NTU), and low SDI (&lt;3). The effluent from the membrane bioreactor can be directly fed to NF or RO when color or salts need to be eliminated for discharge in natural water bodies.

Robust

Our external tubular membranes are less affected by leachate variabilities or the presence of foulant compounds. These are known to affect the performance of submerged membranes. Moreover, fouling control by adaptive hydrodynamic conditions and backwash/CEB can be easily implemented, in order to achieve the most stable operation even under the most challenging conditions.

Operator Friendly

Ease of maintenance. The external crossflow filtration circuit can be easily isolated for any maintenance operation with minimum system downtime. Berghof membranes are easily accessible, robust, and less susceptible to breakage. Resulting in a long membrane lifespan and an easy-to-use system. ​

The MBR process provides the highest possible levels of organic removal, with essentially zero suspended solids in the effluent and excellent nitrification and de-nitrification.

Landfill leachate MBR wastewater treatment - the process

Landfill leachate is treated with the tubular MBR technology. The biological stage combines aerobic and anoxic reactors for removing the significant amount of nitrogenated compounds present in the leachate. The external tubular modules coupled to the biological process produce a free-of-solids permeate that can be discharged to the sewer, or being post-treated with NF, RO or activated carbon for removing the dissolved refractory organic matter and conductivity. By doing so, the effluent can be discharged to water bodies or reused in the landfill site, for irrigation or other uses.
