    Greenbank Group

    United Kingdom

    A specialist engineering company with a global customer base. Greenbank provides a wide range of products and services to companies operating across a number of industries and is now establishing itself in the clean and wastewater sector. For many years the company has utilised the unique properties of volcanic basalt for lining products used in heavy industries such as power generation and minerals extraction. In partnership with Czech firm Eutit, the company has also been pioneering the use of basalt in the renovation and restoration of sewer systems in central European following a series of successful projects in Prague. As a result of devastating floods, the city’s sewer system was extensively rebuilt and upgraded with basalt being used in a number of key locations to provide a new level of security to the system. More than a decade on, the new system continues to perform well and has set a standard that’s now been followed in other European cities. Well suited for the most demanding of applications, thanks to the partnership between Greenbank and Eutit, a wide range of basalt solutions are now available in the UK market. These include products and systems that bring a wide range of benefits to the industry, including: Basalt tiles that can also be used to line existing brickwork, a more cost-effective solution than full replacement, and their reduced drag co-efficient means improved flow – in effect a smaller-diameter pipe or tunnel lined with basalt can carry a higher volume of water than a larger one with traditional brick surfaces. The effective life expectancy of basalt-lined sewer systems is between 100 and 200 years, thanks to their excellent resistance to abrasion and chemical damage – as well as the rigours of high-pressure water jetting that’s often used to clear unwanted blockages. For larger round or ovoid systems, basalt can be used in the lower sections to deal with the wear and tear with concrete upper sections to provide optimum life performance. Alternatively, steel pipes lined with basalt can be produced up to 3000mm diameter producing a lighter therefore lower cost installation option to thick wall concrete. Ease of installation and reduced maintenance costs make basalt ideal for bottom gutters, branch pipes and tubes and slip-resistant elements for walkways, and Greenbank can also supply bespoke-shaped tiles to meet the unique requirements of individual clients. With manufacturing facilities in Derbyshire and Nottinghamshire, supported by the additional capacity and expertise provided by the latest addition to the group, Franklyn Yates Engineering, Greenbank is well placed to react quickly and efficiently to the needs of new and existing clients.

    Sourcing and Managing Water Treatment Chemicals Across Industrial Programs

    Water treatment chemicals fall into distinct functional categories: scale inhibitors and antiscalants (phosphonates, polyacrylates, maleic copolymers), corrosion inhibitors (molybdates, phosphates, azoles, zinc salts), biocides and biodispersants (oxidizing and non-oxidizing), coagulants and flocculants (inorganic aluminum and iron salts, organic polyelectrolytes), pH adjusters (sulfuric acid, caustic soda, CO₂), and specialty products for specific applications such as oxygen scavengers, antifoams, and membrane cleaners. Large industrial sites typically use chemicals from multiple categories simultaneously, managed under a unified treatment program.

    Chemical procurement decisions should be evaluated on total program cost—not just chemical unit price. A lower-cost corrosion inhibitor that requires higher dosing rates or more frequent system cleanings may cost more over twelve months than a premium product at the correct dosing rate. Request program performance guarantees tied to measurable outcomes: corrosion coupon rates below defined mpy targets, scale deposit limits on heat transfer surfaces, and Legionella culture results below regulatory thresholds. Suppliers who offer outcome guarantees accept accountability for program design as well as product supply.

    Supply chain reliability is a significant risk factor often overlooked in chemical procurement. Specialty water treatment chemicals—particularly phosphonates, certain biocides, and high-purity reagents—can have lead times of 4–12 weeks and are subject to supply disruptions. Evaluate suppliers based on their inventory depth, alternative sourcing capability, and willingness to hold safety stock under a supply agreement. Regulatory compliance documentation—SDS, NSF certifications for potable applications, and REACH compliance for global operations—must be maintained current and available on demand.

    Frequently Asked Questions

    What is the difference between an antiscalant and a scale inhibitor in water treatment chemistry?

    The terms are often used interchangeably, but antiscalant specifically refers to threshold inhibitors that prevent crystal nucleation and growth at sub-stoichiometric concentrations—typically 1–10 mg/L for phosphonate-based products. Scale inhibitors is the broader category, which also includes dispersants that prevent crystal agglomeration and adherence to surfaces even after nucleation has occurred. For RO membrane protection, antiscalants must be sized based on concentrate-side water chemistry at design recovery, not feedwater chemistry.

    How do I evaluate competing coagulant products for my clarifier or DAF system?

    Jar testing under representative feedwater conditions is the only reliable evaluation method for coagulant selection. Run jar tests comparing aluminum sulfate (alum), ferric chloride, and polyaluminum chloride (PAC) at varying pH and dose rates, measuring settled turbidity, floc settling velocity, and residual aluminum or iron in the effluent. PAC typically performs better at lower temperatures and a wider pH range than alum and often produces a denser, faster-settling floc. Document the optimal dose for each product at your design pH before comparing costs on a treatment-cost-per-m³ basis.

    What NSF/ANSI certifications are required for water treatment chemicals in potable applications?

    Water treatment chemicals added to potable water must be certified to NSF/ANSI Standard 60, which evaluates contaminant extractability and health risk at the maximum use level. Chemicals used in food-contact steam or direct food contact applications require additional FDA 21 CFR compliance. The NSF Certified Products Database is the authoritative source for verifying compliance—do not rely solely on supplier declarations. Confirm that the specific product formulation and concentration being proposed is listed, not just the product family.

    How should I structure a chemical supply agreement to protect against price volatility?

    Negotiate a base price tied to a recognised commodity index (for example, phosphoric acid or ethylene oxide indices for phosphonate-based products) with a defined adjustment mechanism and frequency. Include a price cap provision limiting maximum adjustment to 10 to 15% per contract year. Secure a guaranteed minimum delivery volume commitment and a safety stock clause requiring the supplier to maintain 30 to 60 days of buffer inventory. Audit rights for raw material sourcing and an escalation process for supply shortfalls should be explicit contract terms.

    Case Study·Paper and pulp mill, North East England
    Challenge

    A paper mill was running an ad-hoc chemical purchasing approach, buying water treatment products from multiple suppliers at spot prices with no formal supply agreements. Chemical costs had increased 40% in two years due to market volatility, and three supply interruptions in 12 months had caused treatment program gaps resulting in scale deposits on steam raising plant.

    Approach

    A chemical supply audit was conducted to consolidate the program to a single provider for all core products (antiscalant, corrosion inhibitor, biocide, coagulant). A 3-year supply agreement was structured with index-linked pricing, 45-day buffer stock held at the mill site, and a performance guarantee tying chemical program outcomes to boiler scale deposit limits and cooling system corrosion rates.

    Outcome

    Total chemical spend fell by 18% in the first year through volume consolidation and index-based contract pricing versus previous spot purchasing. No supply interruptions occurred in the 24 months following agreement signature. Boiler tube inspection after 18 months showed clean surfaces with no measurable scale deposition.

    Questions to Ask Shortlisted Providers

    1. 1

      Are your products listed on the NSF/ANSI 60 certified products database for any application that involves potable water contact, and can you provide the certificate?

      A supplier declaration of compliance is not equivalent to NSF certification; only listed products in the NSF database carry regulatory weight in potable water applications.

    2. 2

      What commodity price index does your pricing track, and how frequently are adjustments applied?

      Without a specified index and adjustment frequency, contract prices are effectively at the supplier's discretion, removing cost predictability.

    3. 3

      What minimum buffer stock will you hold for our critical chemicals, and what is your guaranteed lead time for emergency replenishment?

      A treatment program gap caused by supply failure can cause more operational damage than the chemical cost itself; stock security is as important as price.

    4. 4

      What REACH registration and SDS documentation do you provide for each product, and how quickly are updated documents issued following regulatory changes?

      REACH compliance documentation is a legal requirement for chemicals used in the UK and EU; outdated SDS creates regulatory and COSHH assessment liability.

    5. 5

      Can you demonstrate the performance of your proposed program through corrosion coupon data or scale deposit analysis from a comparable installation?

      Performance claims for water treatment chemicals must be backed by independent analytical data, not manufacturer marketing material alone.

    What Drives Cost in This Category

    Treatment program breadth

    Multi-chemical programs covering scale inhibition, corrosion control, biocide, and pH adjustment have higher total product cost than single-function programs, but each additional function reduces risk and maintenance cost.

    Water system volume and turnover

    Larger cooling or process water systems require proportionally more chemical per treatment cycle; high makeup water consumption due to evaporation or blowdown increases replenishment frequency.

    Chemical purity and certification grade

    NSF/ANSI 60 certified or food-grade products carry a premium of 15 to 40% over industrial-grade equivalents; pharmaceutical-grade products for WFI pre-treatment are priced at a further significant premium.

    Delivery and storage logistics

    Bulk deliveries (IBC or tanker) reduce unit cost compared to drummed products but require on-site storage bunds, spill containment, and secondary containment rated to COSHH and Environment Agency requirements.

    Key Regulations & Standards

    NSF/ANSI 60

    Certifies that water treatment chemicals added directly to drinking water do not introduce harmful levels of contaminants at their maximum use concentration.

    REACH Regulation (UK REACH)

    Requires chemical suppliers to register substances and provide Safety Data Sheets; buyers must confirm REACH compliance for all chemicals purchased for industrial water treatment.

    COSHH Regulations 2002

    Requires employers to assess and control health risks from chemical substances used at work, including all water treatment chemicals; SDS review and risk assessment are mandatory before use.

    BS EN ISO 9001

    Quality management standard that leading chemical suppliers hold; confirms that manufacturing, testing, and supply processes meet independently audited quality system requirements.
