Frequently Asked Questions

ChloroKlean is a UK-based principal stockist of BPR-compliant industrial disinfection products using chlorine dioxide and sodium hypochlorite. We offer biocidal products across six GB BPR product types: PT2 (pools, spas, public areas), PT3 (veterinary hygiene), PT4 (food contact surfaces), PT5 (drinking water treatment), PT11 (cooling systems), and PT12 (slimicides). Our flagship product is ChloroKlean Plus L20 with regenerative chlorine dioxide technology.

Yes. ChloroKlean products are used for control of Legionella pneumophila, Pseudomonas aeruginosa, E. coli and biofilm within their product-type compliance, with efficacy supported by standard laboratory testing and documented case studies. Laboratory testing to EN standards has shown greater than log 6 microbial reduction under the test conditions at low residual concentrations.

Chlorine dioxide (ClO2) is an oxidising biocide used across a wide pH range. It can act on biofilm and forms no chloramines and generally very little THM or HAA, while chlorite, chlorate and other by-products require dosing control and measurement. Performance depends on the product label, target organism, concentration, contact time and water conditions. It is not a reliable Cryptosporidium barrier; UV or filtration is required.

ChloroKlean products are supplied for the Great Britain market in compliance with GB BPR (the retained version of EU Regulation 528/2012), for the specific product types stated on each label. EU BPR, which applies in the EU and Northern Ireland, is a separate regime and we do not claim EU or NI authorisation. Our manufacturing is certified to ISO 9001:2015, Halal, and Kosher standards. Distribution is certified to ISO 9001, ISO 14001, ISO 27001, and ISO 45001.

ChloroKlean products are available in sizes from 500ml to 1000L IBC. Smaller sizes (500ml, 1L, 5L) qualify for LQ (Limited Quantity) shipping. Larger sizes (10L, 25L, IBC 1000L) require full ADR shipping arrangements.

ChloroKlean products are used across multiple industries including healthcare (hospitals, care homes), food processing (meat, dairy, produce washing), water treatment (cooling towers, potable water), hospitality (hotels, spas, swimming pools), agriculture (veterinary facilities, livestock), and industrial applications (paper manufacturing, biogas). Each sector has specific product recommendations based on their compliance requirements.

ChloroKlean products can form part of an HSE ACoP L8 control scheme where their stated use and conditions apply. Product testing reported greater than log 6 reduction of Legionella pneumophila under its specified conditions. Chlorine dioxide can act on biofilm, while site performance requires routine monitoring and corrective action.

Regenerative chlorine dioxide technology refers to ChloroKlean Plus L20's unique formulation that generates chlorine dioxide in situ through a controlled reaction. Unlike tablet or two-part generation systems, this technology provides consistent ClO2 concentration, longer residual protection, and eliminates the need for on-site mixing or specialised dosing equipment.

Yes, ChloroKlean PT5 products are formulated for drinking water disinfection and supplied for their stated PT5 uses. Chlorine dioxide forms no chloramines and generally very little THM or HAA. Chlorite and chlorate must be controlled through product-label dosing and measurement within the applicable limits.

PT11 includes open and closed liquid-cooling and processing systems, but does not establish Plus L20 suitability for every circuit. Assess Plus L20 only where its current label and technical documents support the intended use, considering system design, existing corrosion inhibitors, glycol, materials, operating conditions, dosing and monitoring. No routine recommendation is made for inhibited closed heating or chilled-water loops without expressly supported current instructions and written compatibility evidence. Assess the external spray-water circuit of a closed-circuit evaporative cooler separately from its enclosed process-fluid loop. This is not a blanket ban on chlorine dioxide or a recommendation for remedial or shock dosing. Plus L20 is supplied for stated Great Britain uses under applicable GB BPR transitional arrangements; no full GB, EU or Northern Ireland product authorisation or HSE endorsement is claimed.

Chlorine dioxide has a different by-product profile from traditional chlorine: it forms no chloramines and generally very little THM or HAA, but it can form chlorite, chlorate and other by-products that require control. Suitability for a pool or spa depends on the product label, the written operating procedure and monitoring; it also retains activity over a wider pH range than free chlorine.

ChloroKlean (spelled with a capital K, one word, no spaces) is a UK brand of BPR-compliant industrial disinfection products manufactured by Spa Trade Group Ltd, London. ChloroKlean specialises in chlorine dioxide products for water treatment, Legionella control, food processing, and swimming pool disinfection.
