Hydro Cleansing – Treating Your Drilling Slurry Right!

Slurry is a general word for a variety of waste types. Sludge, manure, drilling waste, bentonite waste can all fall under this term. Hydro Cleansing can collect and dispose of all of it, taking it to our wet waste treatment centre in Croydon.

How much is slurry worth? Farm slurry is worth more than milk these days. Sustainable energy is becoming more and more profitable and farmers are making the most of it. Drilling slurry can’t yet contribute to the energy cycle but it can be compressed to recycle the water used in creating it.

Drilling slurry is created from water used during the drilling process mixing with the waste from the material being drilled through. Drilling slurry varies in density. It can be anything from a dense sludge to a thin cream. That depends on the kind of surface they are drilling through. For instance, a lot of the super sewer’s slurry came out like cream due to the amount of fluid necessary to keep the boring machine working and the chalk rock that they were boring thorough.

It is vital to remove drilling slurry as quickly as possible as it can set solid whilst still appearing movable on the surface. The sediment in the drilling slurry can separate and cause the sediment at the bottom to solidify. The water rises to the top, giving the impression that the slurry is still liquid. Act now! Get your drilling waste treated!

Removal and disposal of drilling slurry

Slurry can include chemicals and require testing before disposal. Hydro Cleansing offer this service as part of our full drilling waste disposal and treatment service.

Our tankers visit a construction site, empty the IBCs and tanks using vacuum suction. The tanks are jetted and vacuumed clean and the drilling slurry is removed for disposal and treatment.

The drilling waste is treated at our Croydon depot. The water is removed and the sediment compressed into a pulp or ‘cake.’

Not for eating, this cake is then sent to landfill and the recycled water is reused to keep our beautiful trucks clean!

Flood annihilated by Megatron and Hydro Cleansing!

Flood annihilated by Megatron and Hydro Cleansing!

 

A life threatening flash flood was vacuumed up in 3 hours by Megatron, Europe’s largest vacuum tanker and the Hydro Cleansing fleet. They delivered an emergency solution to the flash flood in the underpass beside Wallington Station, where 3 cars were swamped by 2m of water on the 7th of June 2016.

1 month’s rainfall fell in 1 hour in a horrendous storm, the lightening from which started several fires across the South of London.  3 cars were trapped. One stalled, the next became trapped as the waters knocked out the engines. The third inexplicably drove into the flood water on purpose. One man was trapped in his car and had to be rescued by a passer-by breaking his car window with a brick, allowing him to get out and wade clear of the water bound car.7V7A0797

Immediately a bulk tanker was dispatched from Hydro Cleansing’s depot in Beddington Lane, Croydon with a police escort and arrived at the scene within an hour of the storm beginning. The three cars were submerged. The 13,000 litre bulk tanker began pumping out the water. 2 combination vacuum tankers followed to the site to remove more of the oil contaminated water. As those tankers left to tip the waste, Megatron, the largest vacuum tanker in Europe emblazoned with transformers graffiti fan art, arrived to clear the rest of the oily waste and empty the 60m soakaway. The bulk tanker returned to relieve Megatron of the waste. The engineers pushed the ruined cars off the road and finally one of Hydro Cleansing’s road sweepers cleared the oily silt from the road The road could then reopen 3 hours after the incident. The fleet of giant orange tankers fulfilled Megatron’s heroic reputation and also provided a neat and tidy end to this environmental thriller.

This kind of flooding is becoming increasingly prevalent. It would be easy to dismiss this as a one off act of God but Paris remains submerged and the forecasts indicate that storms will continue to become more intense as global temperatures rise. “Warming temperatures can make the air hold more water – and that in turn could mean a greater chance for floods”, says Nigel Arnell at the University of Reading, UK. Russell Grattan, Commercial Director at Hydro Cleansing identified that the soakaway under the underpass did have some foliage blocking the flow of the drainage. This flash flood exposed infrastructure weak spots and highlights the need for thorough flood planning to be in place.

VIPs and Pi Day: The Circle of Wet Waste!

Today we have important American visitors from Rain For Rent. This company is a leading provider of temporary liquid handling solutions including pumps, tanks, filtration and spill containment. Their projects range from flood relief to construction site dewatering, sewer bypasses and industrial plant turnarounds. The company is known for its systems engineering expertise and its ability to tackle complex jobs cost effectively. Family owned and operated since 1934, it serves all 50 states of the USA, Canada and the UK from more than 65 locations.

In honour of them we’re celebrating Pi day! The American calendar reads today as 3.14, the initial figures of Pi. It is the crucial mathematical constant ratio between the circumference of a circle and its radius. Circles are a key element in the construction of our cylindrical tankers. We also have a cyclical nature to our wet waste management.

Our innovative tanker Megatron has an elegant cycle which allows for continual work. The beast vacuum sucks in wet waste its recycling unit sifts the water from the other elements of the waste and uses it to continue its high pressure jetting.

The water cycle is a beautiful thing in nature. We contribute to its fluid movement through modern life, in keeping sewers flowing, recycling waste water and much more. As people innovate, water is used in increasingly innovative ways. From harnessing its power to employing it in construction; it is essential in almost any endeavours. Society squeezes every benefit out of water, and it is often left as waste: sludge, slurry, faecal waste etc. At Hydro Cleansing we take these waste products and return them to purified water.

The water cycle flows through both of our businesses and HCL puts it back into its pure form.
