  • What Are You Wasting In Your Handling Of Wastewater And Why
    These wet wells are a collection source for all kinds of debris in addition to what is flushed down the toilets and other drains The disposable wipes the diapers the cloths clothing and whatever else can be forced down a toilet ends up in the wet well Again for all these many years the same old submersible pumping system is expected to move the wastewater to the treatment plant This same old submersible pumping system used to work before flushables were introduced and flushing became the way to dispose of the wipes and other hygienic products There is now a heavy price being paid It is the waste that comes from the many additional hours of labor needed to pull unclog clean and maintain pumps The waste that comes from the equipment needed and the continuing additional man hours used to remove and haul the debris from the wet wells These wastes can end The same old submersible pumps are still being used as the manufacturers have tried to convince you that they have made enough changes to eliminate the problems They have changed the way they want the bottom of the wet well shaped without ever mentioning that they hope to ease the clogging problems They have changed the shape of their impellers claiming that that is the fix The point is that you still have a system that has been used for almost 60 years with no innovation and no sustainability you will still have a wet well to collect raw sewage and all the other debris You still have the odors and the hydrogen sulfide gas and you will still be wasting time and energy to pull clean and maintain the same old submersible pumps as the waste continues In our regulated industry you must comply with the many standards that are promulgated by the federal government as well as meet what your state requires of you There are directives more guidelines and more regulations yet to come Time to study educate evaluate train test and specify must be allocated You will need to acquire the new additional added materials and equipment needed Then you have to implement the new requirements and that too is necessary and costly The hours and equipment used in cleaning and disposing of wet well trash un clogging pumps and hauling debris is also costly and very wasteful Why are you still doing this This does not have to be done any longer Years ago the Europeans solved these issues A lift station pumping system was developed that no longer held raw sewage in a neighborhood while emitting H₂S collecting wipes and other debris no longer required float switches and waiting to reach a level for a pump down Wet wells were no longer used or needed These wet wells that draw down or pump down batch flows and place stress on the treatment plant biomass the valves and the piping system with the all or nothing actions What used to be

  • ECS Service And Repair Archimedes Screw Pumps North Of The Borders For Scottish Water
    to the existing fleet to extend the service life of these traditional pumps The Archimedes screw pump is still one of the most efficient ways of moving large volumes of untreated sewage through elevations under 6 meters in height and as such it is used on the inlets to a large number of waste water treatment sites across the country Its popularity is mainly due to its ability to cope with varying flows and suspended solids whilst producing a vastly extended service life compared to other typical pump types in this application In many cases the screw pump is expected to operate 24 hours per day so reliability is always an essential quality periodic maintenance particularly of the upper and lower bearings and gearbox are required to ensure continued service ECS has been providing extensive refurbishment works to the existing fleet including complete hand re screeding of concrete troughs replacing lower bearings for upgraded fully stainless steel units and full drive train refurbishments with a view to extending the service life of these traditional pumps Full support services are available including electromechanical site services contract lift crane services and retrofitting of stainless steel eco type lower bearings which provide extended service life ECS will be working closely with WGM Engineering which already has a close relationship with Scottish Water and together they will deliver a proactive maintenance and upgrade programme for the screw pump assets While preventative maintenance is always preferable the partnership of ECS and WGM will also have the capacity to react to breakdown situations to ensure continued operation of the affected site ECS is able to provide UK wide turnkey engineering support for all Landustrie screw pumps and those of other manufacturers including Jones Attwood which was originally manufactured by Landustrie Full support services are available including

  • Innovation in Municipal Wastewater Pumping has Already Occurred … It Just Needs to be Recognized
    of newer homes or apartments that are upscale exteriors need to match the surrounding architecture Surge Protection A problem stated is when the pumps cycle on or off or there is a power failure high surge pressures can damage piping The suggested solution is to install surge relief valves at each pump and use soft start stop electrical equipment Rehabilitation of Existing Pump Stations The WEF study found that after approximately twenty years of service that parts are no longer available for electrical controls pumps and valves that need to be replaced Also structures roads and electrical service are often in need of replacement A partial solution offered is that each pump station needs to be examined separately to determine what rehabilitation measures are needed Pumps and valves and other mechanical equipment items are replaced Typically dry pit submersible pumps are used to replace shaft pumps New electrical controls are installed Corrosion resistant materials are installed to replace corroded materials or epoxy coatings are applied to existing surfaces Costs anyone Odor Control Sewage piping designed for future ultimate design flows is often way oversized for initial flows resulting in long pipe retention times and septic odors to the consternation of the neighborhood The suggested solution was adding a chemical feed system to the lift station Again costs Prevention of Leakage into the Pump Station Structures The problem stated is cracks or joints in precast concrete manhole structures used to construct new pump stations that can result in groundwater leakage into the pump station which must be pumped to the treatment facility resulting in unnecessary costs and reduced capacity WEF suggested using butyl caulking for a remedy Provisions for Future Expansion Rapid growth experienced in some areas over the past few years can result in pump stations being undersized to convey projected flow rates If provisions for future expansion are not included in the design the entire pump station or major components of the pump station may have to be replaced The solution for future expansion include the selection of pumps with higher than required motor horsepower to allow the future installation of larger diameter impellers capable of pumping increased flows Energy costs Grit Deposition in Wet Wells Sized for Future Flow Rates Another problem identified in the design criteria for submersible pump wet well sizing can lead to excessive grit deposition in the wet well due to initial low flow conditions The grit can result in serious odor problems and is difficult to remove The solution presented is to provide temporary solid concrete block filler in the wet well areas subject to grit deposition or provide baffle walls to reduce the wet well area during initial low flow conditions In the future when the flows approach the design flow rate the blocks or baffle walls can be removed Remember how I started Innovation in Municipal Wastewater Pumping has Already Occurred It Just Needs to be Recognized Some of us have recognized that innovation has already occurred In fact it occurred
