SPELStorrnceptor" by-pass separators

Maintenance

The SPEL Stormccptor" by-pass separator IS a well proven high quality factory made unit, designed and tested in accordance with the EuropeanStandard BS EN 858-1 and meets the requirements of the Environment Agency's Pollution Prevention Guidelines PPG3 and the ConstructionProducts Regulations.

SPEL Stormceptors are designed for long term peliormance and with SPEL high volume coalescer units, low maintenance.

SPEL Stormceptor by-pass separators are manufactured in class 1 and class 2 models and with or without silt capacity in accordance withBS EN 858-1. The range of models is listed in section 6 or on the SPEL Stormceptor selection chart - available on request.

Chamber 1 Junction chamber 2 Chamber 3

Flow according to nominal size (NSB)

The polluted surface water first enters the primarychamber where silt settles out and is retained. The fuel,oil and other pollutants lighter than water, rise to thesurface and are efficiently skimmed off and transferredto the separation chamber.

All flows within the nominal size pass through theseparation chamber, where the quiescent conditionsallow the pollutants to separate out efficiently. Waterfrom the cleanest zone in the separation chamberflows through a coalescer unit, to remove smallerglobules of oil, up to the junction chamber and thenceto the outlet.

Chamber 1 Junction chamber 2 Chamber 3

Storm flows above NSB

During a storm the level in the primary chamber risesand the storm water passes over the weir into thejunction chamber and to the outlet.

The design keeps the turbulence within the separationchamber to a minimum which avoids disturbing thecontaminants retained.

Maintenance requirements

The SPEL automatic alarm/monitoringsystem will automatically warn you when theSPEL Stormceptor requires emptying of lightliquids, however, silt will accumulate andrequire removing at intervals depending onthe site conditions.

We recommend the SPEL Stormceptor ischecked at 3,6 or 12 monthly intervalsto determine the depth of silt in theprimary chamber.

Where a SPEL automatic alarm/monitoringsystem is not fitted, the SPEL Stormceptorshould be checked at 3,6, 12 monthlyintervals, depending upon site conditions, todetermine the depth of retained pollutants.When the depth of light liquids retained hasreached the predetermined design level inaccordance with the European StandardBS EN 858-1, or if excessive silt hasaccumulated, it should be emptied.

Chamber 1

The inlet connects directly into chamber 1- the primary chamber where silt etc. isdeposited and light liquids are skimmedoff to be transferred to the main separationchamber, chamber 3.

Maintenance requires the removal ofaccumulated silt etc., checking the skim pipeis not blocked and removing floating debris.

Chamber 2

This is the junction chamber where the cleanwater passing out of the main separationchamber and the storm flow over the weirfrom the primary chamber meet and passto the outlet. This chamber is an approvedsampling point if samples are required foranalysis. As it is mainly clean water passingthrough the chamber, maintenance isconfined to checking the weir plate is freeof debris.

Chamber 3

The main separation chamber is where thelight liquids are retained and in the case ofclass 1 Stormceptors, where the coalescerunits are incorporated.

If coalescer units are incorporated, theseshould be removed and cleaned in accordancewith the requirements set out in Data SheetRef. 9.4 steps 1 to 5.

Retained light liquids should be removedfrom the top and any sediment from thebottom. Small Stormceptor by-pass separatorsgenerally need to be completely emptied.

SPEL automatic alarm/monitoring system

If a SPEL automatic alarm/monitoring systemis fitted this will automatically signal whenthe Stormceplor requires light liquids to beremoved. If this system is fitted see ref. 10.1and 10.2.

When emptying take care not to damage orshift the probe protection tube situated in theaccess shaft of chamber 3.

Maintenance procedure

The SPEL automatic alarm/monitoringsystem will automatically warn you whenthe Puraceptor requires emptying. See ref.10.1 and 10.2. Where a SPEL automaticalarm/monitoring system is not fitted, SPELPuraceptors should be checked at three-,six- or twelve-monthly intervals dependingon site conditions, to determine the depth ofretained pollutants and silt in both chambersand the correct operating of the ACO(automatic closure device). When the depthof the oil/fuel retained has reached the pre-determined design level, in accordance withBS EN 858-1, it should be emptied.

Important Note.

When emptying, ensureboth chambers areemptied equally startingwith the oil retentionchamber and then thecoalescer chamber andback again until empty.

RESTRICTED

The purpose of the automatic closuredevice (ACD) is to close the separator offautomatically when the maximum storagecapacity of light liquid is attained.

The ACD is to ensure that in the event of amajor spillage, pollutants do not pass intothe drainage system; it should not be regardedas a substitute for an automatic alarm/monitoring system.

Prior to installation

Prior to installation the ACD retaining tubeshould be covered with polythene to preventingress of concrete etc., which would fall ontothe ACD and upset its calibration.

Operation and maintenance

If the tank should fill with light liquid the ACD,which is calibrated for a specific gravity of0.85, will automatically fall and close off theSPEL Puraceptor.

Normally routine maintenance would includeremoving light liquid intercepted withinthe Puraceptor. If a SPEL automatic alarm/monitoring system is incorporated, it willautomatically indicate when the Puraceptorshould be emptied. Only in an emergency willthe Puraceptor fill to its maximum and operatethe ACD.

In such an event the Puraceptor should becompletely sucked out and the ACD lifted out(see Maintenance Procedure - Ref: 9.4).

Commissioning

After the tank has been installed, leave thewater in.

1. Remove the ACD from the packing box,taking care not to cause damage.

2. Remove the retaining cap from the top ofthe retaining tube in the separator.

3. Insert the ACD into the retaining tube usingthe lifting eye provided, ensuring it floatscorrectly with the float just visible abovethe water level.

4. Replace the retaining cap. This is tosafeguard against the removal of the floatby unauthorised persons or rising above thetube under abnormal conditions.

Note: If the tank's invert depth exceeds 1m it isadvisable to remove the retaining cap prior toinstallation and only replace after inserting theACD, if it is possible to do so from ground level.

Commissioning

After the tank has been installed, leave thewater in.

1. Remove the ACD from the packing box,taking care not to cause damage.

2. Remove the retaining cap from the top ofthe retaining tube in the separator.

3. Insert the ACD into the retaining tube usingthe lifting eye provided. Allow it to sink tothe bottom. The stainless steel retainingplate should seat on the base flange andthe ACD attain its operating position asshown in the open position.

4. Replace the retaining cap This is tosafeguard against the removal of the floatby unauthorised persons or rising above thetube under abnormal conditions.

Note: If the tank's invert depth exceeds 1m itis advisable to remove the retaining cap priorto installation and only replace after insertingthe ACD, if it is possible to do so fromground level.

Larger Models

Where the ACD is al ready positioned in theunit, proceed as follows:

1. Before putting any water in the tank,lift rope attached to ACD up to the nextknot and hang it from the rope hook. Thisis now in the 'operating position'.

2. As soon as the water level in the tank isabove the ACD, the rope must beremoved altogether and the rope hookmust be unbolted. Do not leave the ropehook attached to the shaft. Ensure theACD automatically remains in the'operating position'

3. Tape up or fill the hole(s) in the shaftwhere the rope hook was attached toprevent any backfill seeping into the shaft.

Maintenance

Dependent upon site conditions it is advisableto remove the ACD periodically taking carenot to raise it too quickly and damage theplastic/copper float. Clean from debris/silt toprevent premature closing. Check the seatingin the base unit is free of debris/silt that couldprevent proper closing in an emergency.

! SPEL coalescer units - with handles

The SPEL Puraceptor class 1 separator and SPEL Stormceptor class 1 by-pass separatorsincorporate coalescer units. The coalescer units provide a coalescence process for the separationof smaller globules of light liquid pollutants before final discharge to the surface water drain.

Prior to Installation

1. Remove any strapping/ropes which havebeen used to hold the coalescer units fromshifting in transit.

2. The access shaft(s) above the coalescerunits should be covered with polythene toprevent ingress of concrete, dust, debrisetc. which could clog the foam inserts.

3. On completion of the installation, checkthat the coalescer unit is inserted securelyinto the base socket.

This facilitates easy insertion and removal of coalescer units. The system is robust,manufactured throughout in stainless steel and the action positive, leaving no doubt thecoalescer unit is located properly.

Brackets fixed to the top and bottom of the coalescer unit simply engage the stainless steel guiderail fixed to the top of the stub access shaft. The coalescer is then lowered in the normal way,being guided at the correct angle into the conical base unit which finally locates the coalescerunit into its final position.

Extension guide rails can be incorporated into SPEL extension shafts to suit (preferably whenordered with the separator).

SPEL coalescer unit lifting/locating/locking system for positive location andsecurity locking

SPEL coalescer units lowered into theseparator with the SPEL guide rail systemare easily guided into the base unit's conicalmoulding to automatically seat correctly.

However, when the separator is full of water,debris or sludge accumulated over a periodcould prevent the coalescer unit fromre-seating correctly after servicing.

The coalescer unit lifting/locating/lockingsystem ensures the coalescer unit is seatedcorrectly and can be locked into position toprevent tampering.

The system is particularly suitable in SPELSeparator + Econoskim systems where thetotal contents of the separator are not emptiedon servicing.

The system comprises a robust stainless steellifting and lowering handle that locates on theguide rail system. When the coalescer unitis correctly located in the conical seating inthe separator the handle will align with guiderail top bracket ie. the handles slotted holeswith the top bracket clip locking groove, seediagram. When aligned the stainless steel clipcan be located through the slots and lock intoposition on the top bracket.

The stainless steel lifting handle can be extendedto suit deep tank inverts and provide easyaccess for lifting manually or with the SPELtripod and hoist utilising the lifting hook.
