Capabilities

Programmes, not products.

Prosep doesn't sell a catalogue. We engineer a chemical and equipment programme around your plant's systems, risks, and KPIs — then price it transparently against that scope.

We control calcium carbonate and silica scaling in high-cycle cooling systems with targeted phosphonate and polymer programmes, dosed to a saturation index we monitor on site, while protecting yellow metals with azole-based corrosion inhibitors.

Pillar 01

Asset reliability & uptime

We protect the physical plant — the heart of your operation. Our programmes prevent the corrosion, scaling, and biological fouling that cause costly failures and unplanned downtime, extending asset life.

  • Boiler water treatment
  • Cooling water treatment
  • Boiler acid wash & chemical cleaning
  • Anti-scalant & anti-corrosion programmes
  • Legionella risk control
  • Building & HVAC closed-loop and cooling tower management

We manage feed-water chemistry across RO and ion exchange trains, controlling silica, hardness, and biofouling to protect membrane life and hold product conductivity within specification.

Pillar 02

Process & production yield

Water is a critical ingredient in production. We manage its quality and chemistry to improve product quality, increase throughput, and reduce operational cost. Better water means a better, more profitable product.

  • Process additives & dosing control
  • Reverse osmosis chemicals & membrane care
  • Potable water purification
  • Flocculation, coagulation, thickening & filtration
  • Potable system disinfection
  • Clean-in-Place (CIP) programmes
  • Dosing & control equipment

We treat complex effluent through staged pH correction, coagulation and flocculation, and metals precipitation, with EPSE recovery where the stream carries value — so discharge meets DWS limits and water returns to process.

Pillar 03

Compliance & sustainability

Environmental regulation is a major business risk. We deliver end-to-end solutions that treat complex effluent, manage risk, and meet discharge and safety standards — with reuse and recovery built in.

  • Effluent & wastewater treatment
  • EPSE metals recovery
  • Municipal & sewerage treatment chemicals
  • Site risk assessments
  • Water reuse & recovery
  • Water treatment equipment & services

Equipment & control

Chemistry is only half the programme.

Dosing and control equipment, installed and commissioned by our engineers, keeps every programme accurate — with monitoring that proves performance against the KPIs we agreed.

Not sure which programme fits your plant?

That's the point — neither are we, until we've seen it. Book a site assessment and we'll map your systems, sample your water, and tell you exactly what we'd do and what it would cost.
