Leaks and spillages of oil and fuel are washed down drains every time it rains and, unless intercepted, find their way into water courses polluting reservoirs and rivers. This can have a disastrous eﬀect on plants and wildlife. A substantial amount of oil pollution is collected in sites such as garage forecourts, large car parks and fuel storage depots and this must be intercepted to avoid the risk of prosecution.
The Environment Agency has published Pollution Prevention Guidelines ‘Use and Design of Oil Separators in Surface Water Drainage Systems: PPG3’. These set out the standards with which separators must comply and assist in deciding on the need for a separator at a site and the size and type that is appropriate. These Pollution Prevention Guidelines PPG3 require separators to be tested in accordance with the standard test procedure based on the European Standard BSEN858-1:2002.
The Hyrdaprotector is the most widely used separator where it is acceptable to treat the first flush and normal flows up tov6.5mm/hr rainfall. This covers approximately 90% of all rainfall events in Australia. Any excess rainfall is by-passed without treatment.
These are used when it is considered an acceptable risk not to provide full treatment for high _lows, for example, where the risk of a large spillage and heavy rainfall occurring at the same time is small. They are especially suitable for situations where the main requirement is to trap spillages.
The Hyrdaprotector is the first by-pass separator certified to BS EN 858-1.
The installation of the Storm protector follows a simple process. A complete installation hand book is supplied to ensure the installation goes smoothly and to plan. The guide provides advice for lifting, OHS measures, handling techniques and other important requirements. Installation is typically:
The HYDRAPROTECTOR is suitable for many applications. Its high filtration rate and large array of configurations and sizes allows for this system to be suitable in almost all situations. Its ability to also be combined with other filtration systems, such as the HYDRAPROTECTOR, as a combined system ensure that this system can be used in a wide range of applications. The most common applications are listed below:
Consists of a baffle, coalesce filter, flow director, discharge riser and inspection cap. Also includes the guiderail insertion system.
Typical sites: Medium to high risk oil/fuel storage and handling areas. Filling stations (PROTEC Water PureProtector forecourt separator FP1C). Commercial vehicle/plant maintenance yards and heavily contaminated industrial areas.
Additional extras for the dual chamber system include automatic closure device, coalesce filter in second chamber, dropper unit, dual access manways.
Typical Sites: High risk oil/fuel storage and handling areas, illing stations (PROTEC Water PureProtector forecourt separator FP2C), heavily contaminated industrial areas, commercial vehicle/plant maintenance yards, power stations and sub-stations. Two chamber models provide protection to the coalescer foam inserts from silt and heavy fuel/oil contamination by causing the gross pollutants to settle on the chamber floor.
Initial Containment Chamber 1: Total Suspended Solids (TSS) silt, sediments, sludge and gross pollutants are trapped and settle on the chamber floor. Light liquids are skimmed oﬀ into Chamber 2.
Containment Chamber 2: Light liquids are contained and non-turbulent low through two horizontal treatment chambers uses the under low principle to retain light liquids in all low conditions. Third Coalesce Chamber: Light liquids separation is enhanced, reducing to 5mg/L or less prior to discharge.
Class 1 separators, which are designed to achieve a concentration of less than 5mg/l of oil under standard test conditions, should be used when the separator is required to remove very small oil droplets, such as those arising from car park runoff.
Class 2 separators are designed to achieve a concentration of less than 100mg/l oil under standard test conditions. They are suitable where a lower quality requirement applies, for example where the effluent passes to a foul sewer.
PROTEC WATER products are Quality Assured under BS EN ISO 9001:2000 - manufactured in a modern manufacturing plant ensuring the highest standard of quality control. Protector separators are filament wound by an advanced, patented, chop hoop filament winding process. This process produces not only circumferential strength as found in helical wound tanks, but also high longitudinal strength. The interlaminar shear strength permits tanks to be cut for manholes and pipework without undue loss in strength.
The dished ends are incorporated during the filament winding process, enabling tanks to be moulded and completed as virtually ‘one piece’ units. The manufacturing process is carefully monitored with a digital read out system. Chopping glass, winding glass, the resin-rich inner layer and main laminate resins are kept within specification parameters, thus minimising human error. Quality control procedures require each tank to be carefully inspected and tested.
All of the Protector range have been individually engineered to handle the toughest environmental situations and proven in the toughest environments such as high-water tables and volcanic soils. Problems in these areas have been solved with the installation of the StormProtector.
The Packaged StormProtectors are engineered to the following Standards:BS4994 – 1987, AS/NZS 1546.1:1998. Hydraulic and civil engineering can also be provided to your requirements.
