Waste Water Treatment
The processes involved in waste-water treatment include physical processes such as settlement or flotation and biological processes such as aerated lagoons, activated sludge or bio-films in trickling filters. Other physical methods such as filtration through sieves may be used in specialised circumstances such as de-watering waste-water sludge.
To be effective, sewage must be conveyed to a treatment plant by appropriate pipes and infrastructure and the process itself must be subject to regulation and controls. Some wastewaters require specialized treatment methods. At the simplest level, treatment of sewage and most wastewaters is carried out through separation of solids from liquids, usually by sedimentation. By progressively converting dissolved material into solids, usually a biological floc, which is then settled out, an effluent stream of increasing purity is produced.

STP TECHNOLOGIES :
- MBBR :
The MBBR process is based on the aerobic biofilm principle and it operate on utilizing the advantages of activated sludge and other biofilms system without being restrained by their shortcomings.the main theme of this technology is biofilm carrier elements that are made from polythene or plastic . these elements provides large protacted surface area for the biofilm and optimal condition for bacteria culture to develop and flourish.the MBBR system is installed to increse the existing capacity of system. MBBR increse the capacity of existing system without increasing the footprints byconducting new plants .
- MBR :
MBR technology come up as an advanced waste water treatment technology of choice over the traditional methods such as ASP which has been the conventional municipal waste water technology over the past decades. MBR provides the large number of advantages releating to process control and product water quality.MBR is a hybrid concept of a conventional biological treatment and physical liquid solid seperation using membrane filtration in single system.
