Mode of disposal of treated water : Recycling in irrigation

“Promax Hybrid STP "ProMax Hybrid STP" Biological treatment plants are extremely compact and efficient compared to regular

systems, clog free, handles shock loading, ready to be operated, fully automatic, skid mounted, and up front

central control.

Our package plants are constructed with simplicity in mind. The operation is robust and experience indicates that

one man inspecting the system once a week is sufficient. Regular service and maintenance can be done by in-

house personnel.

The "ProMax Hybrid STP" system is based on the High-Speed Bio Technology biodegradation and filtration, which

is unique due to its compactness and performance in respect of volumetric efficiency. These technologies are

combined in a prefabricated; skid mounted and standardized tank system with variable length, suitable for

overseas transportation in ISO freight containers.

PROCESS DISCRIPTION:

The first and the second chamber of "ProMax Hybrid STP" is filled with Bio Media and water. The last chamber,

which is a Micro Filtration, is filled with water only. Before starting pumping of waste water, the system blowers

start. The blowers force air through the manifolds into the first 2 chambers of the bio system. The influent

wastewater enters the first chamber and comes in constant contact with the Bio Media and air. Large surface area

@ 400 – 500 m2/m

3 provided by the Bio Media helps the bacteria to form large colonies on the Bio Media. Circular

motion of the media is caused by the air flow. Each element of the media slowly moves in a circular motion from

the surface to the bottom and then upwards again. During this movement, it is in constant contact with the injected

air. Slowly a bio film develops over each element, which disintegrates the BOD present in the effluent.

From the first chamber the effluent flows to the second chamber through the perforated screen at the top. The

same treatment is repeated in this chamber and the remaining BOD from the first chamber gets fully digested. The

treated water then enters the third chamber.

After the bio-degradation process in the MBBR tank, the treated water which enters the third chamber. Here the

treated water is directly sucked out via the Membrane modules which are immersed in the same tank; Effluent from

this Micro filtration Membrane is consistent in quality as membrane is an effective barrier against suspended solids

and microorganism.

The accumulated biomass is discharged to the Filterpress/sludge drying bed/sludge digestor for further dewatering.

The treated water then passed through the UV disinfection system.

Each system is carefully designed to clients exact specifications regards to influent loading and effluent

requirements in respect of COD, BOD, TSS, Ammonia or Nutrients.

ADVANTAGES COMPARED TO CONVENTIONAL BIOLOGICAL PROCESS:

In general, the main advantages shown by the moving bed process compared to conventional biological processes

are:

A reduction in the volume of the biological reactor because it uses a support or carrier that gives a high specific

surface. They are very flexible processes since they are based on the percentage of plastic support used in the

reactor. It does not require reactor biomass recirculation – This gives rise to the fact that the biomass does not

depend on the final separation of the sludge and as a consequence typical problems found in conventional

activated sludge processes related to the sedimentation properties of the sludge (filamentous bulking, etc.).

The operation and control is simple for this type of processes.- On the one hand the process avoids blockage

problems and consequently regular cleaning periods, in addition it is not necessary to control the sludge purging

since the system keeps the biomass in the reactor until it comes off the support.
