WATER TREATMENT.
ENGINEER THE WATER.
NOT JUST THE WASH.
Industrial washing creates a continuous wastewater management obligation. Alkota engineers complete water-management infrastructure — multi-stage vacuum recovery, media sand filtration, closed-loop recycling, and thermal evaporation.

CLEANING DOESN'T END
AT THE NOZZLE.
Every litre of hot water delivered under 300 BAR of pressure becomes an immediate environmental and site management requirement.
Industrial washing strips compacted diesel soot, mineral oils, hydraulic fluid, heavy silt, and surfactants off commercial machinery. Under UK law, this effluent cannot be discharged into clean rainwater surface drains, soakaways, or local watercourses.
Facilities must manage the full lifecycle: capturing the spray runoff, separating suspended solids, stripping emulsified hydrocarbons, meeting sewerage undertaker trade effluent consents, and conserving clean metered water through closed-loop recycling.
Surface Runoff Containment
Preventing contaminated wash water from migrating across open yards into permeable soil or surface water gullies.
Suspended Solids Trapping
Separating aggregate, brake dust, and heavy clay before pump wear and line blockages occur.
Hydrocarbon Emulsification
Breaking hot water and detergent chemical emulsions to strip free oils below 5 mg/L compliance targets.
Trade Effluent Consents
Adhering to regional water authority limits for COD, TSS, and pH when discharging to municipal foul sewers.
Metered Water Conservation
Reclaiming and filtering up to 90% of process water to combat escalating commercial water utility bills.
Hazardous Waste Volume Reduction
Thermal evaporation of spent coolant and chemical washes to eliminate expensive per-litre tanker haulage.

Multi-Stage Media & Vacuum Filtration
Water passes through progressive treatment beds designed to capture finer suspended particulate matter and break down chemical/detergent matrices.
Alkota CSF deep-bed silica sand and multi-grade gravel media or VFS negative-void vacuum filtration chambers that maintain high throughput without premature filter fouling.
Alkota CSF-5 & CSF-10 Media Filtration Systems, 8-VFS-1 Negative-Void Vacuum chambers.
Properly dimensioned for continuous industrial throughput without slowing operator wash cycles.
THREE ALKOTA TREATMENT TECHNOLOGIES.
Not accessories. Core industrial systems engineered to solve vacuum water reclaim, permanent media filtration, and hazardous liquid waste evaporation.
Alkota CSF Series
Stationary Modular Media Sand Filtration Plants
The Alkota CSF series represents our flagship stationary water-treatment and closed-loop recycling architecture. By routing wastewater through a 300 lb high-efficiency media sand bed coupled with an above-ground coalescing separation tank, it delivers continuous, ultra-low-maintenance filtration for permanent facilities.
Commercial fleet haulage depots, bus & rail yards, plant hire facilities, agricultural machinery maintenance, and municipal depots.
THE COMPLETE
WASH-WATER ECOSYSTEM.
Alkota does not treat water treatment as an afterthought accessory. We engineer the complete cycle: from the high-pressure hot water washer, to the wash bay catchment, to multi-stage filtration, and back into the machine buffer tank.
Bespoke Mobile Trailers & Skids
Integrated 8-VFS-1 vacuum filtration, baffled fresh/reclaim water tanks, hose reels, and diesel power generators on highway-certified chassis.
Fixed Multi-Bay Wash Plants
Centralised plant rooms with automated CSF sand bed media filtration, underground reticulation, overhead 360° booms, and automated backwashing.
TARGETED INDUSTRY SCENARIOS.
Transport & Fleet Haulage Depots
High daily wash throughput of HGVs, trailers, and vans generating hundreds of litres of effluent loaded with traffic film, diesel residue, and road grime under strict local water company scrutiny.
Dedicated wash pad with silt catchpit feeding an Alkota CSF-10 Media Filtration plant. 90% of water is recycled back into the hot pressure washer fleet.
Closed-loop wash recycling with overflow to foul sewer via Class 1 coalescing interceptor.
ENVIRONMENTAL
RESPONSIBILITY.
Under the Environmental Permitting Regulations 2016, discharging commercial vehicle wash effluent into surface water drains or soakaways is an illegal act carrying unlimited fines.
Alkota equipment can form part of a properly designed wash-water management strategy. Site-specific discharge and trade-effluent requirements should always be verified with your regional sewerage undertaker (e.g., Thames Water, Severn Trent, United Utilities) or environmental regulator (EA, SEPA, NRW).
Class 1 coalescing separators target ≤ 5 mg/L hydrocarbon discharge. Class 2 gravity interceptors target ≤ 100 mg/L for foul sewer discharge under consent.
