MODULAT STP SYSTEMS
BIO3T-STP

The Bio3tT-STP is a modular wastewater treatment system that can be sized according to the project needs. It is a multi-stage biological purification process to treat the wastewater to effluent standards suitable for discharge back to the environment or for reuse as second class water.

 

FLEXIBILITY IS THE KEY

Above are some of our installations varying from 50 people and upwards. Biggest installation on the Bio3T-STP modular systems to date is for 2000 people installation in 4 stage system so that the plant can be systematically put into use by demand and/or maintenance schedule a considerable advantage over conventional single package units.

 

MODULAR | FLEXIBILITY | FAST TURNAROUND

The design of our Bio3T-STP is based on the concept of flexibility and fast demanding markets. Conventional STP systems are single package systems which include the primary section, the biological section, and the final settlement. in the Case of the Bio3T-STP these sections have been designed separately and in a plug and play configuration. This concept ensures that an STP is always readily available no matter what the scale of the project.

The heart of the process is a submerged, fixed film plastic media that promotes biomass growth. This is achieved by injecting oxygen in the water through a set of special HDPE membrane diffusers located at the base of the second stage tanks. The fine bubble aeration is carefully controlled, providing optimum oxygen transfer rates and scouring to slough off excess biomass while keeping the thickness of the fixed biological film at optimum levels. The final settlement tanks are designed to provide maximum settlement of any suspended solids prior to discharge, with a small sludge return pump returning flow back to the biological tanks and the primary settlement tanks .

MODULAR STP KEY FEATURES

Modular and scalable to the project requirements.
Plug & Play installation and commissioning concept.
All key parts that are subjected to the natural elements are manufactured from GRP.
Export optimized.
Easy maintenance of the HDPE membrane Diffusers
Bio3tTM require no sludge level control, providing easy operation and a more stable process

SINGLE HOUSEHOLD UNITS

The single household units are self-contained units. designed to cater to a small unit of up to 7 people. it has a wide door opening at the top for easy access and maintenance of the unit.

 

CASE STUDY

Our key market so far is based in Ireland and thanks to our key collaborators FM Environmental Ireland.

Location: Golden Ridge Housing Development, Rush, Co. Dublin 1500PE STP

Application: Staged parallel system for new housing development, this way the STP was commissioned according to the demand of the project.

Equipment: 

  • Pumping station

  • Four independent parallel streams each treating 375PE

  • Concrete primary tanks, 24ea ST2 (media) and 8ea ST3 (hopper tanks) tanks

  • Flow measurement

Effluent ​Production: 300m3/day (peak flow of 37.5m3/h = 3DWF)

Effluent Quality: BOD < 20mg/l. SS<30mg/l, discharged  into local sewer mains
