INDUSTRIAL CLEANING.
ENGINEERED AS INFRASTRUCTURE.
Alkota engineers turnkey industrial wash systems around your specific assets, contamination profile, throughput demands, site footprint, water treatment strategy, and lifecycle support. Every installation is site-specific.
A wash plant is a production system.
When a facility must process vehicles, rolling stock, roadway matting, sheet piling, or industrial components through repeated high-intensity cleaning cycles, the correct solution depends on far more than PSI.
A high-pressure washer is an individual tool. A wash plant is an integrated infrastructure asset: combining heavy mechanical reticulation, thermal water generation, automatic sequencing, civils interfaces, solids evacuation, oil separation, water recycling, and long-term asset management.
We design systems from first principles — calculating asset geometry, cycle dwell time, effluent loading, and power constraints to guarantee operational continuity and statutory environmental compliance.

Conveyorised Cleaning System
Heavy mechanical handling with 360° synchronized high-pressure cleaning.
Continuous heavy-duty variable-speed conveyor systems engineered for repetitive planar assets, stripping heavy mud, grease, and biological contamination through synchronized multi-angle rotating spray arrays.
Rig mats, access roadways, sheet piling, trench boxes, heavy panels.
Automated Variable-Speed Conveyor with Sensor Interlocks
100% Closed-loop continuous multi-stage recycling & solids extraction.
30 to 60 units per hour continuous.
Anatomy of a Wash Plant.
The cleaning equipment and the water infrastructure are designed together. Below are the 12 functional stages of a comprehensive high-throughput industrial wash installation.
Asset Entry & Positioning
Traffic Control & ApproachOptical sensors, ground loops, and guidance curbing ensure the asset is safely positioned with correct clearances before wash sequence initialization.
Pre-Wash / Bulk De-Muck
High-Volume StrippingHigh-volume low-pressure flood arches or wash monitors soften compacted mud, road salt, and heavy aggregate prior to detergent application.
Chemical & Detergent Application
Low-Pressure Foam DwellAutomated chemical proportioners apply clinging alkaline foam or degreasing agents to break down traffic film and hydrocarbon bonds.
Primary High-Pressure Wash
Schedule 80 Thermal PowerContinuous-wound thermal heating coils deliver water at up to 95°C and 345 BAR across oscillating spray arches or manual lance drops.
Underbody & Wheel Wash
Chassis IntegrityTargeted high-pressure spinner nozzles flush wheel arches, brake assemblies, axles, and under-chassis cavities from below-ground spray bars.
Effluent Containment & Collection
Impermeable Sump GridsGraded impermeable concrete bays and heavy-duty galvanized trench gratings route all wash water into primary collection sumps.
Solids Separation & Settling
Sediment Baskets & TrapsGravity settlement pits, sediment baskets, and automated screw conveyors remove heavy gravel, sand, and suspended silt down to 50 microns.
Oil & Contaminant Management
BS EN 858 SeparationCoalescing plate interceptors and floating surface skimmers strip free petroleum hydrocarbons and oily films from the effluent stream.
Water Treatment & Filtration
Multi-Media PurificationDeep-bed silica sand, multi-stage cartridge polishing, or vacuum filtration systems remove fine particulate and chemical residues.
Buffer Storage & Closed-Loop Reuse
Sustainable RecirculationTreated water is transferred to high-capacity holding reservoirs with automated level controls, supplying up to 90% recycled water back to the pumps.
Automation & PLC Master Controls
Industrial InstrumentationIP66 PLC control suites govern pump sequencing, variable speed drives, interlocks, temperature modulation, cycle logs, and safety systems.
Asset Exit & Clearance
Operational HandoverAutomated exit barriers open, wash counters increment, and throughput telemetry records the completed cycle into the site operations register.

The Wash Plant Architect.
Not an instant online shopping basket. Industrial wash plants are complex engineered capital projects. The Wash Plant Architect allows you to structure your asset profile, throughput demands, water constraints, and site requirements into a preliminary engineering project brief.
Industrial instrumentation.
Engineered reliability.
Modern industrial wash plants operate as integrated process control systems. We design bespoke electrical and automation architectures utilizing industrial PLCs, variable speed drives, optical profiling sensors, and safety interlocks.
Where specified, wash systems are delivered remote monitoring capable — structured to accommodate live telemetry for operating hours, cycle counters, filter differentials, and predictive maintenance alerts.
Built for demanding applications.
