Oil & Grit Separator

The Oil & Grit Separator uses a specifically designed mesh filter, wier plate and limited orifice outlet to separate the grit and floating contaminant in different containment bays. It's within the Grit containment bay that the Sediment being transported by the fluid can drop out and settle to the bottom. This allows the Floating Contaminant to continue unabated to the Floating Contaminant containment bay.

Once the Floating Contaminants have been captured, the transporting water can continue its flow free from Oil & Grit out of the trap.

We harness the available energy in the water flow to transport the pollutants into the containment bays. This is the basis of our catch phrase 

 


Where Used

The Oil & Grit Separator is used in sites with low to medium velocity flows where there is an available head loss (depth to invert) .

 


Site Requirements

Target Pollutant Class

The Oil & Grit Separator is targeted at capturing:

Water Sources 

The Oil & Grit Separator is suitable for treating the following water sources:

  • Pipes

Velocity

The Oil & Grit Separator is primarily used for sites with low to medium velocity flows. 

Grades

The Oil & Grit Separator is suitable for grades from less than 0.05%  to to any grade. Please note while we can cater for high grades some design modification may be required.

Treatable Flow

The Oil & Grit Separator is suitable for treating flows from as low as a 3 month ARI to a 100 year ARI.

We don't treat the "first flush", we treat the whole flow for the duration of the event.


Configuration

Size

The size of the Oil & Grit Separator is dependent on the:

  • Cross Sectional area of the Water Source, 
  • Velocity, 
  • Grade,
  • Treatable Flow 

To give you an idea of sizing here is a sample set of configurations.

Note: These figures are indicative only and do not represent the largest or smallest sizes we can treat. If you need an estimate size for your plans please contact us and we will be able to provide this information to you over the phone if you can provide some or all of the Site Requirements.

Lidded

The Oil & Grit Separator is generally a lidded solution, however this cannot really be established until the site requirements are known.

Pollutant Storage

The Oil & Grit Separator uses on-line storage.

Trap Access

Depending on the site and cleaning requirements the Oil & Grit Separator can be accessed manually.

 


Installation

Standard equipment and modular construction combine to make installation convenient with minimum interruption or alteration to existing conditions. Deep excavation is generally not required with the Oil & Grit Separator.

 


Cleaning

Cleaning of the Oil & Grit Separator is dependent on the site requirements but any of the following can be used with this design of trap.

  • Eductor Vacuum
  • Manual
