Membrane Bio Reactor (Wastewater)

Membrane Bio Reactor (Wastewater) 

Membrane bio reactors (MBR’s) are used within an activated sludge waste water treatment process to filter out suspended material, increasing the MLSS levels and produce a high quality filtrate. The increased quality of the activated sludge returned to the aerated zone reduces the required aerated tank volume and the MBR’s use of suction to draw filtrate through micro filtration or ultrafiltration fibres reduces the filtration tank size due to the increased potential flux rates. With the introduction of an MBR to an activated sludge system, a system can have either an increased flow for the same foot print or the same flow for a greatly reduced footprint

Memstar provides submerged membrane modules (SMM) that are being used in some of the largest MBR solutions in the world:

• Chengdu Xingrong Project (Plant 3, 5, 4 & 8), 750 000 m3 per day
• Beijing Huaifang water recycling project, 600 000 m3 per day
• Lanzhou Qilihe project, 400 000 m3 per day

Memstar provides different fibre solutions (PVDF NIPS for simpler waste waters and PVDF TIPS for more challenging waste water) alongside the incredibly energy efficient macro bubble generation used in the scouring process for waste water treatment. This allows for an energy usage of 0.029 – 0.034 kWh/m3 for the air scour process. The largest MBR module skids designed by Memstar allow for up to 3 000m2 of surface area holding 100 SMM modules.

All these benefits of cutting edge development stemming from their head office in Singapore can be broken down into something that offers

1. Energy efficient aeration
2. Optimised fibre selection able to handle the most difficult waters
3. Increased surface area of modules dramatically reducing footprint resulting in capital expenditure savings
4. Advanced cost effective manufacturing processes.
5. Extensive references and supported engineering guidance
