Chemical Cleaning Solutions for Industrial Systems
Removing Scale, Fouling, Organic Deposits, and Membrane Contamination to Maximize Operational Performance

Industrial Cleaning Solutions for Deposits, Scale and Slime

Deposits, fouling, scale, biological growth, and process contamination can significantly reduce the performance, efficiency, and reliability of industrial systems. In heat exchangers and cooling systems, deposits restrict heat transfer and reduce cooling capacity, leading to higher energy consumption and increased operating costs. In pulp and paper processes, deposits can create operational instability, sheet defects, and reduced product quality.

The formation of deposits may result from poor water quality, process upsets, inadequate chemical treatment, biological contamination, or the accumulation of organic and inorganic materials over time. Left untreated, these deposits can lead to equipment damage, unplanned shutdowns, and increased maintenance expenses.

A successful industrial cleaning program should maximize deposit removal while minimizing surface attack, operational downtime, and environmental impact.

Modern industries demand cleaning solutions that deliver:

  • Low maintenance and operating costs
  • Minimal production downtime
  • High operational safety
  • Improved equipment reliability
  • Enhanced energy and process efficiency

When Is Industrial Cleaning Recommended?

Industrial cleaning should be considered under the following conditions:

  1. Long-term equipment standby, with or without water.
  2. Inadequate or ineffective chemical treatment programs.
  3. Following maintenance, repairs, or system modifications.
  4. Reduced heat transfer efficiency or increasing energy consumption.
  5. Evidence of scale, fouling, biofilm, sludge, or process deposit accumulation.


Regular and specialized cleaning helps maintain operational readiness, maximize asset performance, and prevent unexpected production interruptions.

Selecting the Right Cleaning Technology

Choosing the correct cleaning solution requires understanding the nature and composition of the deposits.

  • Acidic cleaners are typically used to remove inorganic deposits, mineral scale, and metal oxides.
  • Alkaline cleaners are effective against organic fouling, oils, greases, and biological contaminants.
  • In complex cases, a combination of cleaning technologies may be required to remove mixed deposits efficiently.


Deposit analysis and system assessment are strongly recommended to ensure the safest and most effective cleaning approach.

What can Kurita offer you?

  • Preliminary investigation of pre-set boundary conditions, e.g. circuit materials, available time, existing technical equipment.
  • Exact analysis of the composition of the deposits.
  • Implementation of the customized cleaning procedure.
  • Proposals for an optimization of the water treatment, e.g. the use of our products for hardness stabilization or corrosion inhibition in water systems, to avoid corrosion and deposits.
