CLOSED-LOOP CLEANING ON SENSITIVE ASSETS.
Zero-runoff mobile wash systems designed for water treatment plants, power substations, railway sidings, and coastal ports.
What Is Being Cleaned
Utility providers, railway maintainers, and port authorities clean transformers, rolling stock bogies, water intake grates, and oil storage bunds. Strict Environment Agency (EA) regulations prohibit any contaminated hydrocarbon runoff from entering watercourses or surface drainage.
Site & Technical Constraints
Setting up fixed wash bays at every substation or remote coastal jetty is economically unfeasible. Contractors must bring complete mobile water treatment plants capable of capturing 100% of wastewater, removing hydrocarbons down to <5 mg/L, and recycling the water on-site.
THE RECOMMENDED TRAILER ARCHITECTURE.
An enclosed heavy tandem 3,500kg mobile plant room integrating an Alkota DED diesel machine, 2,000L twin holding tanks, an Alkota VACGD positive-displacement vacuum extractor, and an Alkota 8-VFS-1 negative-void vacuum filtration system.
Zero-Runoff Closed-Loop Recycling
Filters wastewater down to 20 microns and removes oils via activated carbon canisters, recycling water continuously to the pressure pump.
Environment Agency <5 mg/L Standard
Treatment exceeds BS EN 858 class 1 discharge standards, allowing legal operation adjacent to rivers, reservoirs, and marine docks.
10 kVA 3-Phase Onboard Power
Super-silent diesel generator powers the entire vacuum and filtration plant without relying on grid power.
Weatherproof Plant Room Housing
Fully enclosed lockable bodywork protects expensive filtration sensors, control valves, and carbon media from corrosive salt spray.

Utilities, Water Infrastructure & Marine Ports Engineering FAQs
How clean is the recycled water produced by the VFS-1 system?
The Alkota 8-VFS-1 vacuum filtration system removes suspended solids down to 20 microns and polishes free hydrocarbons down to under 5 mg/L, making it clean enough for continuous reuse in Alkota high-pressure pumps.
Does this system require trade effluent permits for on-site washing?
Because the closed-loop system recycles up to 90% of water and retains the contaminated sludge in onboard filter media for controlled off-site disposal, no contaminated water enters public drains.
