The AGUAPURO PSTP is a unique combination of aeration and attached growth on fixed film that results in an easy-to-install and operate, prefabricated solution of outstanding performance and efficiency. Features - All-in-one single tank packaged sewage treatment plant. - Modular design : 5 - 100 m3/day - Compact and simple to operate - Minimal maintenance - No corrosive components Advantages - Minimal land usage - Minimum power and chemical requirement - Easy to install ,monitor and relocate. - Bar Screen screens out the non-compressible and non bio-degradable solids above 15mm particular size. This will protect from major systems damage & safe guard the biological process. - Aerobic Treatment: The effluent then enters the bio-zone, which combined fixed film reactor as forced aeration system using diffusers and blower. The fixed film reactor provides a solid surface area for micro-organisms to attach themselves; these then feed on the organic mater present in the effluent. Sludge recirculation is provided to optimize the efficiency of the system. - Final Settlement: The treated water effluent enters the final settling zone for settling finer particles. - Chlorination: Chlorinated water is taken to the Storage tank for further use directly or through territory treatment system.AGUAPURO PSTP models are available for flow rates above 100 m3/day. Applications - Hotels - Restaurants - Holiday Resorts - Golf and Country Clubs - Housing Complexes - Townships - National Parks Industrial Estates - Existing Plant Upgradation

SAFF /MBBR Media

• SAFF / MBBR treatment is based on aerobic attached growth process and used in the secondary treatment of effluent/sewage treatment plant.
• the equipment consists of specially designed synthetic media or Bio Wheel Media, which facilitates attached fixed film growth of micro-organisms.
• The media is supported by channels or Frre Moving
• diffusers are provided for efficient oxygen transfer.

mbbr (moving bed bioreactor)

• thousands of polyethylene biofilm carriers operating in mixed motion within an aerated wastewater treatment process.
•  every biofilm carrier adds productivity via the provision of an active surface area sustaining bacteria within protected cells.
•  it is this high-density population of bacteria that achieves high-rate biodegradation productivity within the system.

units required:

• raw sewage collection sump
• equalization tank
• aeration tank
• membrane bioreactor

mbr (membrane bioreactor):

• results in high efficiency in removal of bod, cod, suspended and dissolved solids. Meets all effluent standards.
• tertiary treatment doesn’t required as membrane system is used.
• membrane filtration process produces an effluent which have low suspended solids concentration and turbidity units.
