Bentonite Slurry Disposal in London

There are many different types of drilling muds and drilling slurries, such as bentonite, used to decrease friction during drilling.

Bentonite clay is a popular choice for drilling slurry, and it's a material often used in the process of horizontal directional drilling. Directional drilling is used to access underground. This can be more practical than vertical drilling when looking to reduce the environmental impact of the work.

We provide massive onsite jet vacuum tankers to ensure regular removals and legal recycling of liquid waste. This is liquid waste removed during the bentonite slurry drilling process.

Sustainability Permits

Sustainability permits are needed for a wide range of different activities including emissions from nuclear power stations and sewage treatment plants, to scrap metal yards, and other areas that might pollute the air, water or land. On constructions sites, Hydro Cleansing have several methods of dewatering from excavations: 

✓ Wellpoint method of dewatering excavations

✓ Eductor Wells method 

✓ Open sump pumping method 

✓ Deep well method

Waste Carrier Licence

From January 2014, new regulations mean that companies transporting waste as part of their business (whether it’s their waste or someone else’s) have to register for a Waste Carriers Licence. This includes contractors like Hydro Cleansing but also any company that conducts water discharge activities. We highly recommend giving us a call to see what we can do for you today to avoid costly fines.

EWC Codes

There are over 650 EWC codes in total, providing the backbone of environmental protection. They are used to ensure that all treatment plants are licensed for the processing of correct waste streams. We process a variety of EWC Codes at our Waste Recycling Facility.

What Type Of Wet Waste Is Processed?

Our expertise and experience covers the processing of a wide range of materials including: Drilling slurry Gully waste Road sweepings Inlet grit Storm tank cleaning Sludge dewatering Culvert Cleaning

Accessibility to Treatment Plant

Our site is open to all for licensed liquid waste recycling. Vehicles are escorted to our operated weighbridge for the gross weight prior to tipping at our treatment plant. Once tipped they return to the weighbridge in order to establish the net weight and fill out any relevant paperwork. The site is large enough to accommodate all types of road sweepers and even fully laden articulated tankers.

Weighbridge System

Our weighbridge system is regularly calibrated to ensure it is both accurate and compliant. We use the Gross and Net system across the haulage and environmental services sector and HGV drivers to ensure accurate weights are obtained with minimum disruption.

Vehicle Wash Bays

Whilst attending our treatment plant, operators can take advantage of the ability to wash down even the largest vehicles, using the clean water produced by our recycling plant. 

As with all other aspects of environmental service, this wash down is controlled by legislation and must be performed in an area where fuel oil interceptors are both installed and operational. 

We use our high pressure water jetting technology and degreasing to prevent cross contamination. This whole process of recycling and reuse, creates a closed reuse/recycle loop.

What is Polymer Slurry?

Polymer slurry is an alternative to bentonite slurry. Both clays are used as a flocculation agent during the drilling process. 

The main difference is that polymer slurry can be used  as many times as required, making it the more efficient solution. This is because it does not absorb contaminants.

Our Wet Waste Service Steps

Our commercial wet waste services follow the same basic steps:

  1. Establish an EWC code (usually EWC 20 03 03)
  2. Agree quotation amount and quantities
  3. Signed WAF Waste collection
  4. Gross weight measured
  5. Transfer waste to treatment plant
  6. Net weight measured Invoice with required documentary and compliance records

Sewer Grit

At Hydro Cleansing we receive unlimited volumes of sewer grit. We always make sure to process it into a useful building material and water at our London depot. Sewer grit builds up in areas of the sewer network where the flow rate is lowest and can easily block the system. Instead of dumping wet waste in landfills, we provide concrete slurry removal to remove small stones, dirt and winter grit.

Street Sweeping

HCL are leading experts in the safe disposal of street sweepings. We are committed to providing our treatment facilities to any and all road sweeper operators. We provide our expert service from our London depot, to independent operators to prevent businesses dumping wet waste in landfills.
