Industrial cleaning & maintenance

Industrial services companies often need support in purifying wastewater from cleaning and maintenance processes for end-clients – and activated carbon is an ideal treatment solution. DESOTEC can partner with you, providing mobile sustainable water and liquid filters for short or long-term use to remove a wide variety of compounds such as: residues of chemicals used in industrial processes; adsorbable organic halides (AOX) from chlorinated compounds in cleaning, disinfecting and degreasing fluids; and colours from fluorescent fluids used to highlight microcracks. After filtration, the water is safe for discharge to wastewater treatment plants (WWTPs), making this a cost-effective alternative to specialist disposal. Your clients may also be able to reuse the water in their industrial processes, boosting sustainability.

The cleaning of equipment such as tanks and reactors releases vapours that are likely to contain volatile organic compounds (VOCs), solvents and hydrogen sulfide (H₂S) – all of which can be removed through activated carbon filtration. Cleaning fluids also give off fumes, probably chlorinated. DESOTEC filters remove these compounds, protecting occupational health and air quality, and controlling odours during cleaning and maintenance processes. 

DESOTEC filters can also act as a good temporary replacement for permanent installations such as thermal oxidisers (RTOs) that are undergoing maintenance.  

Activated carbon filters enable industrial services companies to comply with laws to control odours and protect air quality, the environment, food quality, and occupational health and safety. They also enable end-clients to maintain equipment according to manufacturers’ warranties. If end-clients want to avoid downtime during maintenance and cleaning, then our filters can act as a reliable and compliant temporary replacement. 

DESOTEC has regional know-how to support you in achieving compliance, and can deliver filters rapidly for immediate operation in urgent situations. Safe, sustainable and compliant filtration waste management is included in our service. With laws likely to get stricter in the coming years, it’s crucial that you protect your business and that of your clients by having a reliable purification solution ready to go. 

Activated carbon filtration is a Best Available Technology (BAT) for many pollution treatment applications, and is often the most cost-effective and sustainable option – but it does depend on various factors.

For example:

• For temporary usage, DESOTEC filters are mobile and rental – unlike more permanent installations such as RTOs.
• Where air or water flow is discontinuous, activated carbon is generally more cost-effective than alternatives such as thermal oxidisers (RTOs).
• If space is tight, DESOTEC filters have a smaller footprint than most alternatives.
• If treatment is needed immediately, our filters can be delivered fast and are plug-and-play – some alternatives have a lengthy lead-in time.
• If your needs might change in the future, our systems are modular – other technology might be less adaptable.
• If flow rates, concentrations and compounds are changeable, activated carbon is generally more versatile than alternatives. 

DESOTEC is keen to help customers find the best treatment for their needs, and our experts will tell you if they think another technology might be more suitable than activated carbon.

Activated carbon is a very versatile technology, so there are many ways to optimise set-ups – e.g. placing filters in series, using different carbon grades, or combining filters with complementary technology such as scrubbers.

DESOTEC solutions offer a low total cost of ownership (TCO), with minimal capex costs. As they are supplied on a monthly rental basis, they are cost-effective for temporary cleaning and maintenance projects, but can also be written into service plans. Furthermore, sustainable carbon waste handling is included in DESOTEC’s service, keeping end-clients’ sites pristine and dust-free. In most cases, we can reactivate the carbon for reuse, cutting costs and boosting sustainability.
