Sintex Sewage Treatment Plant :

NAVYAA WATERTECH SOLUTIONS , provides the best solution to treat sewage water through sewage treatment plants based on anaerobic and aerobic process and designed to have a dual functions for efficient treatment of domestic wastewater from toilets , bathrooms , kitchen and washing area.

In line with their innovative past Sintex Industries has tied up with M/S Aqua Nishihara Corporation , Japan , world leaders in the area of providing sewage treatment solutions. In all over the world it has been recognized that decentralized wastewater treatment is a better alternative to a centralized wastewater treatment system from the angle of investment, energy consumptions and efficiency. There are so many areas within cities, towns and villages that are impossible to cover through centralized treatment systems. It has therefore become imperative to evolve decentralized treatment systems that take care of proper treatment and disposal of sewage.

Sintex Sewage Treatment plants are available in two series..

PWTS – STBF SERIES

Under this series the sewage treatment plants are available from 1200 ltrs to 6000 ltrs.. It is a compact, modular, polyethylene tank which can be easily used in a decentralised manner anywhere for sewage treatment of Domestic and commercial places.

  • Rust proof and leak proof
  • Impermeable to roots of trees

Operations Principle of 'Sintex' PTWTS

Solid Separation Zone :

First stage transforms the influent solids to settled solids while allowing scum to float on the surface. It is a septic zone in which settled sludge is stabilized by anaerobic digestion. The treatment efficiency of the chamber is in the range of 30 - 40 % BOD removal.

Aeration Zone:

Second stage is the aerobic zone in which the air bubbles pass through plastic media installed inside the tank which in turn increases the surface area and retain micro-organism long enough to digest the organic substance remained. Air is provided through blowers and more contacting time with the slime on the plastic media, occurred, more efficient the digestion process would be. BOD removal is around 60- 70%.

Accessories:

No internal electrical items Air blower External piping, vent pipe, air blower , inlet and outlet.

NBF SERIES

It is a compact FRP tank which can be used in decentralised manner anywhere for aerobic treatment of Sewage water and ideal for medium to large residential complex and commercial complex. Sintex is working with MBBR technology to achieve BOD <30 mg/l which results in absolute odourless water good enough for gardening and similar purposes.

Advantages of FRP material of construction

Sintex sewage treatment plants are made of only FRP ( Fibre reinforced plastic ).It’s advantages are


  • Good temperature insulation throughout the year.
  • Bacteria work on same efficiency and consistent performance 12 months.
  • FRP material is inert to corrosion; life time is more than 50 years.
  • FRP material is inert to fungal growth.
  • Impermeable to root growth.
Benefits of Sintex STP- NBF series
  • Compact tubular tank easy to transport.
  • Not much civil work involved, easy to install.
  • Sludge removal is once in 3 years.
  • It works from no load to peak load.
  • Complete underground system, hence no footprint.
  • Can take weight upto 30 tonnes, hence may be installed at pathway or under car parking.
  • Absolutely no maintenance product; requires no supervision.
  • Electricity consumption is less than half as compare with conventional systems.
  • System may be relocated or upgraded easily.
  • Lifetime more than 50 years.

OPERATION PRINCIPAL OF NBF SERIES

Solid Separation Zone :

First stage transforms the influent solids to settled solids while allowing scum to float on the surface. It is a primary sedimentation zone in which settled sludge is stabilized by anaerobic digestion. The treatment efficiency of the chamber is in the range of 30 % BOD removal.

Aeration Zone:

Second stage is the aerobic zone along with plastic media installed inside the tank which in turn increases the surface area and retain micro-organism long enough to digest the organic substance remained. Clear water will overflow the next treatment chamber. Air is provided through blowers and more contacting time with the slime on the plastic media, occurred, more efficient the digestion process would be. BOD removal is around 60-65%

Final Sedimentation Zone:

Final stage involves the sedimentation where organic wastes are settled in the Sedimentation zone. The settled waste in the bottom of the tank is pumped back to the primary sedimentation zone as a return sludge having active biomass (MLSS) to increase the efficiency of the system and ensure the effluent quality meets the stipulated standards.

Accessories:

External Recirculation pump is provided for return sludge Automatic control panel provided for the blowers and pump Piping including vent pipes, blower pipe, recirculation pipe, inlet and outlet pipe
