Oil Water Separators (OWS)
Clearmake™ oil water separators are designed to remove free floating hydrocarbons such as diesel, hydraulic fluid and oil as well as heavier suspended solids from a waste water stream. This form of treatment is the minimum required prior to trade waste (sewer) discharge for any wash bay where hydrocarbons may be present.
Clearmake™ Separators are approved by:
Sydney Water - Ref: 2006-365
WA Water Corporation - Ref: JT1 2010 01224V01
Standard Clearmake™ separators are constructed from high quality 304 stainless steel. They can however be upgraded to 316 grade stainless steel for marine or corrosive environments. Larger models have frames manufactured in hot dipped galvanised steel.
Superior Vertical Tube Coalescing (VTC) technology facilitates improved separation, via the unique spiral tubes, designed to assist in exercising the free floating oils to the surface. These specifically designed VTC blocks also provide optimum flow, serviceability and durability.
Standard treatment rates range from 800 to 56,000L/h and custom systems can be manufactured to treat flow rates in excess of 250,000L/h.
Clearmake™ controllers are manufactured to Australian Standards and configurations are available to meet Council requirements Australia wide. All separator control systems can be designed and manufactured to meet higher IP ratings, intrinsically safe standards for hazardous areas, spill control and general or specific mine specifications. The Clearmake™ standard controller comes with IP 53 rated GPO to facilitate site installation and pump replacements. Higher IP rated enclosures are available upon request.
The Clearmake™ Vertical Tube Coalescing (VTC) technology is effective in removing small oil droplets, with a 95% removal rate of droplets as small as 10 micron and a 100% removal rate of droplets as small as 25 micron. Where oil droplet size is considered to be predominantly smaller than 10 micron i.e. emulsified, physical separation technology becomes less effective and chemical separation technology such as Dissolved Air Flotation (DAF) should be considered.
Refer to the following test results that were undertaken to demonstrate the effectiveness of the Oil Water Separator in removing free floating hydrocarbons form a wastewater stream and the additional reduction that is possible when filter bags are used. The following independent product appraisal report undertaken by the Water Services Association of Australia (WSAA), validates the Clearmake™ design as fit for purpose to treat oily water prior to entering a sewer network.
