subject: Keeping Industrial Lagoons Free Of Contamination And Hazardous Waste Through Drainage And Clearing [print this page] An industrial lagoon may, from time to time, require draining or cleaning due to contamination either of hazardous waste or non hazardous waste.
A lagoon is a body of comparatively shallow salt or brackish water separated from the deeper sea by a shallow or exposed sandbank, coral reef, or artificial structure.In industrial terms it can be used to hold waste water or used as a treatment pond to provide artificial aeration promoting the biological oxidation of waste.
There are many other biological processes for treatment of wastewaters, for example activated sludge, trickling filters, rotating biological contactors and biofilters.They all have in common the use of oxygen and microbial action to treat the pollutants in wastewaters.
Cleaning an industrial lagoon and keeping it free from contamination requires a specialist team using the right equipment.
A full site survey will need to be carried out before any work is started to take account of any risks and produce a method statement and analysis of the waste being removed.
Vehicle mounted high volume/low pressure or low volume/high pressure water jetting units can be used to clean smaller area such as drains, sewers or interceptors.
Hazardous and non hazardous waste can be removed in a special fleet of tankers with barrels manufactured from mild steel or stainless steel.
These may be coated with specialist linings depending on the waste being removed.Where a large volume of liquid need to be moved then liquid ring pump tanker units can be used to remove the waste quickly and efficiently.
Jetter recycling units have the capability to operate as both an air mover and a conventional vacuum unit.Combined with the continuous recycling of jetting water, more time is spent on the cleaning process before replenishing the jetting water.
If large volumes of waste are to be removed from lagoons or interceptors the waste can be processed on site using a mobile or static filter presses.The modern day filter press can nowadays remove the filtrate from the sludge and change it into a dry filter cake.
The filtrate can either be reused or disposed of to drain away so disposal costs are reduced.Ensuring that the waste from the cleaned lagoon is removed to a registered waste disposal site is crucial.
Heavy penalties, including fines and prison sentences, have been awarded to companies failing to comply with waste disposal legislation.Relevant documentation will need to be completed for the disposal of the waste.
Draining lagoons and other bodies of water offers a useful maintenance operation.Over a period of time deterioration can take place for many different reasons.
Once drained, a CCTV survey can quickly identify the reason for any problems and allow recommendations to be made on the best possible solution.
