STORMWATER TREATMENT

EcoTreat Class 1 Bypass BP Series

The Global Water EcoTreat Class 1 Bypass Separator is an in-line device designed to treat stormwater run-off from paved areas where low levels of hydrocarbon residuals and gross pollutants are present, whilst allowing high flows to pass without restriction. 

Features of the Bypass device include: 

  • tough one-piece roto-moulded construction
  • compliance to EN 858-1 and performance tested by the University of South Australia
  • cost-effective compared to alternative designs
  • suitable for above and below ground installations

FEATURES

APPLICATIONS

The DrainAce Compact is commonly found in restaurants, basements of high-rise buildings, boardrooms, laboratories, doctor or dental surgeries, construction sites and portable buildings. Units are also available for greasy waste discharge from grease arrestors. 

APPLICATIONS

The EcoTreat Class 1 Bypass Separator is suitable for the following applications:

  • carparks
  • shopping centres
  • warehouse loading areas
  • industrial yards
  • waste depots
  • heavy vehicle maintenance and storage areas
  • airport aprons and tarmacs
  • road tunnels

PRODUCT INFORMATION

The Bypass Oil/Water separator is suitable for primary and secondary treatment in low risk areas, removing hydrocarbons and suspended solids, whilst preventing on-site flooding from storm events.

Water quality certification

Full-scale performance testing of the EcoTreat Class 1 Bypass Separator was conducted by the University of South Australia in accordance with Stormwater Australia guidelines for suspended solids and nutrient removal. The unit achieved Class 1 gravity supply device requirements, in accordance with EN 858-1.

How it works
  1. Solids Separation Chamber: All incoming first-flush run-off passes through the settling chamber, allowing settling and removal of sediment and other suspended solids.
  2. Oil Separation/Storage Chamber: Captured oil and other hydrocarbons are held in the oil storage chamber. The capacity of this chamber meets the requirements of EN 858-1.
  3. Coalescing Treatment Device: The flow then passes through the coalescing treatment deice which combines small droplets of light liquids such as oil and diesel, allowing them to be trapped and removed, ensuring the oil content in the outflow is less than 5 mg/L. This meets the requirements of a Class 1 gravity supply device, in accordance with EN 858-1.
  4. Bypass Function: During high-flow events, the excess flow bypasses the settling chamber and the coalescing device, ensuring that trapped pollutants are not diluted or washed through. This bypass feature ensures that the site is protecting from flooding in storm events.

Note: the treatment flow rate depicts the maximum flow the EcoTreat Bypass Separator can treat through the coalescing unit, while the bypass flow rate is the maximum rate at which partially treated flow moves through the unit in a storm event.

The GPT can be used to protect pumping chambers and down-stream stormwater detention tanks or treatment devices. Multiple units can be installed to ensure effective site coverage and maximise first flush catchment.  

Based on Global Water’s proven glass-reinforced concrete (GRC) 600 mm x 600 mm sumps, the EcoTreat GPT offers optimum versatility, with the outlet able to be installed on-site at any invert to suit site requirements.  

A galvanized grate suitable for pedestrian or light vehicle traffic is supplied as standard. A heavy-duty grate is available as an option.
