Liquid Treatment Plant

BKP's Liquid Treatment Plant

Our Liquid Treatment Plant

Since inception in 1964, the demand for cost effective, efficient liquid treatment on the South Coast has grown significantly, so BKP Waste Recycling & Ltd have invested heavily in their liquid treatment facility located onsite in Romsey, Hampshire.

Through our unique site permit and supported by specialist equipment, we are able to accept a large variety of sludges, liquid and dry waste streams into our treatment plant. If you are interested in downloading our full acceptance list, please download the LTP Acceptance List .

Waste Reduction & Dewatering System (WRDS)

A key part of our liquid treatment facility at BKP, this system works hand in hand with our polymer dosing unit (PDU). The dewatering system is designed to separate solids from liquids, reducing the overall volume of the waste.

Waste is deposited into the system and pulled through the PDU using a built-in sludge pump. By injecting polymers into the liquid, solids are flocculated, and the liquid is free to move through specialist screening nets inside the WRDS. The liquid is then recovered for discharge into our trade effluent sewer whilst the solids are captured within the WRDS container for remediation and recycling.

Additionally, the unit is fully modular and can be transported using one of our hook-lift RORO vehicles for temporary installation on a client’s site. The WRDS is ideal for pond, lagoon, large interceptor and below ground tank cleaning, negating the need for expensive transport costs and disposal of water, as the water can be discharged into the existing drainage system, watercourse or storage tanks for re-use.

The dewatering system can reduce waste up to 85% when desilting and can be operated with a minimal team of operatives. The WRDS system is fully supported by EA permitting for use remotely under our mobile plant permit EPR/FB3901HT.

Oil & Water Separation System (OWSS)

BKP’s oily water separation system contains heated coils within the base of the unit. The oily waste is discharged into the reception tank which contains fine screens to remove the majority of the solids from the liquid. It is then pumped into the OWSS which is connected to an industrial water heater with a 150kw two stage burner, enabling us to heat the liquid and efficiently separate the oil and water.

As the levels rise within the system, the oil is skimmed off and recovered oils are bulked in readiness for recycling. The water is then discharged through the release valve at the base of the OWSS and passed through our coalescer system to remove any further hydrocarbon deposits prior to being pumped back into our storage tanks, for reuse in the oil and water separation process.

The Centrifuge

BKP is committed to providing best available techniques, and as such has invested heavily in waste reduction equipment to help protect our plant by providing a solution to heavy sludges and difficult waste streams.

The centrifuge decanter system does exactly this, by using centrifugal force to provide waste volume reduction on a much larger scale than the WRDS. By introducing polymers, the separating of liquids and suspended solids can be achieved at an impressive 40m3 an hour, producing a cake that can be utilised in bio-remediation processes.

This type of equipment can deal with both hazardous or non-hazardous oily sludges, and the bowl speed can be controlled remotely until optimisation of the introduced waste stream is achieved. Not only does this kind of technology enable a higher volume of waste to be kept out of landfill, but it also contributes to improving our carbon footprint by reducing vehicular movements before and after treatment.

Being one of the very few licensed hazardous transfer stations in the Southern region to have this technology, BKP can continue to provide existing and potential customers a more environmental and cost-effective solution to manage their waste.

    Call us today!

    As part of a total waste management service, BKP has a varied fleet of vehicles to suit every application which is specifically designed to carry bulk liquids, dry waste and other hazardous materials; enabling us to provide a collection, treatment and disposal service to all our clients. 

    Our vehicles are maintained to the highest standards and operated by our own experienced and dedicated drivers and operatives. However, our license does permit third parties to use our facilities and we welcome all enquiries and opportunities.
