Our MBBR technology ensures the lowest Capital Expenditure by optimizing the use of cost-effective materials and resources. Moreover, its inherent efficiency in biological wasteWater Treatment guarantees low Operating Expenditure through reduced energy consumption, minimal maintenance requirements, and extended service life, setting it apart as the most cost-effective choice compared to traditional treatment technologies.

A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of some material, such as rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media, over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media. Aerobic conditions are maintained by splashing, diffusion, and either by forced-air flowing through the bed or natural convection of air if the filter medium is porous. The treatment of sewage or other wastewater with trickling filters is among the oldest and most well characterized treatment technologies.

Technical Description...
A basic A/0 system will yield simultaneous biological removal of both BOD and phosphorus. Where only BOD removal is required, the basic process is optimized to provide significant performance benefits relative to conventional activated-Sludge Processes. In either case, the same basic configuration and biological processes, shown above, are utilized. The A/0 process, which uses an anaerobic selector to achieve enhanced performance, is a high-rate variation of the conventional activated-sludge process. The anaerobic selector is established by mixing and contacting influent BOD-containing wastewater with recycled activated sludge in the absence of supplied oxygen or oxygen-containing gas. In a subsequent step, the anaerobically formed mixed liquor is aerated in an oxic zone and finally separated in a secondary clarifier, which functions in the same manner as in conventional activated-sludge processes.

Longanti A/O Process improves upon the activated sludge process by using an anaerobic selector to develop a selective biomass that is naturally reoccurring in nearly all treatment plants. The process enhances phosphorus removal while reducing sludge-bulking organisms...

Membrane filtration has a major role in water and wastewater treatment, which is superior to the conventional water technologies with a proven better performance and more efficient economics. The basic membrane processes are microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO). Separation ranges for those membranes are as follows: 100 to 1000 nm for MF, 5 to 100 nm for UF, 1 to 5 nm for NF, and 0.1 to 1 nm for RO.  For more than the last 10 years MBRs have emerged as an effective secondary treatment technology by using membranes in the range of MF and UF.
