Cleaners to prevent biological contamination and preserve the circuits against corrosion

Sustainable cleaning with Ferrolin® and Alberol®

Deposits in industrial installations can affect and minimize the performance of a system and even damage the constructions material. In heat exchangers, this may cause significant heat transfer reduction, which leads to lower efficiency so limited cooling capacity. In paper machine loops deposits cause defects in the finished paper.

The formation of deposits can be caused by various reasons, e.g. poor water quality, insufficient chemical treatment, process upsets. Due to severe problems which can arise, excessive deposits should be removed by a chemical cleaning.

The aim of a successful cleaning is a wide removal of all deposits with a minimal attack of the surface and the highest possible environmental compatibility.

The customer demand is to achieve this cleaning with low working costs and a minimal downtime with high working safety

It is highly recommended and part of good practice protocols to apply a cleaning under the following circumstances:

  • Long standby of the system without and with water, 
  • Inefficient chemical treatment, 
  • After subsequently maintenance work in the plant.

Appropriated cleanings keep machines, pipes and systems available at any time and helps to avoid unexpected downtimes. A regular and specialized cleaning is one of the key factors for operational readiness of production facilities. Therefore Kurita proposes acidic, alkaline and neutral cleaners to remove deposits, scale, fouling, dirt, grime or impurities. To select the right parameters of the cleaning process, it is very important to know the composition of the deposits. Therefore we recommend to analyze the deposits. In addition the thickness of the deposits should be known.

In general, acidic cleaners should be chosen to remove inorganic deposits and alkaline cleaners should be applied to remove organic material

In individual cases, it may be necessary to apply two cleaners in succession: for instance, if thick deposits with approximately half of calcium carbonate and half of organic matter have to be removed. In this case, an acidic cleaner is applied first and after rinsing, an alkaline cleaner should follow.

Alberol® and Ferrolin®: products for the removal of scale, metal oxides, deposits, oil, mud.

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 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.
