The cooperating client is AQUA NORDIC, a high-end water service group headquartered in Stockholm, Sweden. It is a renowned mid-to-high-end supplier of water purification systems, industrial pure water equipment and commercial water treatment solutions across Northern Europe, serving star hotels, top medical institutions, precision electronics factories and premium drinking water brands. Its business covers Sweden, Norway, Denmark and Finland.
The enterprise operates a large fleet of spiral-wound reverse osmosis, nanofiltration and ultrafiltration water treatment systems, with long-term demand for specialized acid and alkaline membrane cleaners. Its previously imported cleaners suffered from long procurement lead times and high overall costs, prompting the client to shift sourcing to Chinese supply chains. The client’s annual customized demand totals 62 tons, split into two categories: acid membrane cleaners and alkaline membrane cleaners.
The client’s product specifications far exceed standard industrial-grade alternatives. The cleaners must be compatible with high-end composite membrane materials, feature low corrosion, high descaling efficiency, zero residue and strong biocompatibility, while complying with Northern European environmental regulations and original equipment manufacturer (OEM) operational standards. After consulting multiple domestic Chinese manufacturers, all could only offer generic off-the-shelf products that failed to match its personalized technical indicators, operating conditions and environmental compliance standards. Repeated failures in customization led the client to entrust HiSiaddi with full-cycle support covering R&D, sample preparation, testing, mass production and delivery.
Formulated to remove calcium carbonate, calcium sulfate and metal oxide scale; low-corrosion formula with polyamide RO membrane corrosion rate ≤ 0.1%; stable pH value at 2.5±0.2; free of strong oxidizing agents and phosphates; post-cleaning membrane flux recovery rate ≥ 98%; no residue after rinsing.
Targets organic contaminants, biofilm and colloidal fouling; adopts biodegradable surfactant system; pH controlled at 11.0±0.3; low-foam formulation compatible with automatic online cleaning equipment; 28-day biodegradability ≥ 96% to meet Northern European environmental access standards.
Two separate formulations (ambient-temperature and low-temperature types) to adapt to cold winter operating conditions in Northern Europe; highly concentrated liquid format to cut warehousing and cross-border logistics costs; full ingredient traceability with third-party test reports and safety documents recognized by local Northern European authorities.
1.
Mismatched Performance of Generic Products Conventional acid and alkaline cleaners on the market have high corrosion coefficients, causing permanent damage to high-end composite membranes with prolonged use and shortening membrane element service life. Many generic products contain phosphorus, generate excessive foam and exhibit poor biodegradability, directly violating local environmental regulations.
2.
3.
Formulations Incompatible with Low-Temperature Operating Conditions Factory environments in Northern Europe drop to low temperatures in winter. Generic cleaners tend to layer and precipitate active ingredients under cold conditions, drastically reducing cleaning efficiency.
4.
5.
Insufficient Customization Capacity of Manufacturers Most producers only manufacture products based on national standard generic formulas, lacking specialized R&D experience for high-end membrane materials. They also lack familiarity with Northern European environmental and chemical regulations, making targeted formula adjustment and supporting compliance documentation impossible.
6.
7.
Instable Batch Consistency & Incomplete Documentation High-end water treatment projects require minimal deviation of product indicators across batches. Multi-language SDS, ingredient declarations and environmental test reports are mandatory, which ordinary manufacturers cannot fully provide.
8.
HiSiaddi quickly assembled a special cross-functional team covering formula R&D, production process, compliance certification and application technology. The project was executed in four phases: targeted formula R&D → lab sample production → on-site simulation testing → mass production rollout, aligned with the client’s membrane models, operating conditions and regulatory standards.
In collaboration with a professional domestic water treatment additive manufacturing base, HiSiaddi discarded generic strong acid/alkali systems and redesigned formulas from scratch:
· Acid Cleaner: Replaced highly corrosive inorganic acids with a composite organic acid + corrosion inhibitor compound system, supplemented with dedicated membrane protectants to strictly control corrosion rates while enhancing chelating power for efficient inorganic scale removal. All phosphorus-based additives were eliminated to deliver a phosphorus-free formulation.
· Alkaline Cleaner: Adopted naturally derived non-ionic surfactants paired with biodegradable additives to achieve low-foam performance for automatic cleaning lines. Low-temperature stabilizers were incorporated to maintain uniform solution without active ingredient precipitation between 0–25°C.
Two independent formulas (ambient-temperature and low-temperature grades) were finalized per client requirements, with precise control over pH, active ingredient content, corrosion rate and foam height.
Five batches of lab samples were produced first. Laboratory simulations replicating the client’s on-site water quality, fouling types and cleaning cycles were conducted to test membrane flux recovery, membrane surface damage, residual chemical content and low-temperature stability. Parallel testing for biodegradability, phosphorus-free status and corrosion rate was completed, with detailed data reports generated for every batch.
After selecting the two optimal formulas, samples were sent to the client’s Swedish laboratory for blind third-party testing against their original imported cleaners. All indicators met or exceeded the benchmark imported products, securing formal technical approval from the client’s engineering team.
Dedicated independent production lines were allocated for the customized cleaners, with separate feeding, stirring and filling processes to avoid cross-contamination with generic cleaners. All production parameters, raw material ratios and reaction temperatures were fully standardized to minimize batch-to-batch deviations in pH and active ingredient concentration. Concentration technology was upgraded to boost product potency without compromising cleaning performance, lowering the client’s logistics expenditure.
In accordance with Northern European chemical regulations and EU CLP standards, bilingual English-Swedish Safety Data Sheets (SDS) and technical product manuals were compiled from scratch. Authorized third-party laboratories conducted environmental, biodegradability and membrane compatibility testing to issue fully recognized official reports. A complete document package including ingredient traceability lists and certificates of origin was prepared and delivered alongside each shipment.
1.
Fully Compliant Customized Products The 62 tons of customized acid & alkaline membrane cleaners were shipped, cleared customs and delivered in three consignments. Post-deployment across the client’s water treatment projects, descaling and organic fouling removal efficiency met all targets. Membrane corrosion issues were fully eliminated, extending membrane service life. The formulations remained homogeneous without layering or precipitation under low-temperature Northern European operating conditions.

3.
Zero Compliance Risks The full set of multi-language documents and test reports smoothly passed local Northern European regulatory inspections and end-user acceptance, with zero compliance objections raised.
4.
5.
Dual Optimization of Costs & Operational Efficiency High-concentration formulations significantly reduced the client’s overall procurement and logistics expenses. Low-foam properties of the alkaline cleaner accelerated cleaning cycle throughput for automated equipment.
6.
7.
Long-Term Deep Partnership Established The client fully replaced its previous high-cost overseas supplier and signed a three-year annual procurement framework agreement with HiSiaddi. Subsequent demand for auxiliary chemicals including civil water treatment detergents and pipeline descaling agents was also transferred to HiSiaddi. The client acknowledged that HiSiaddi delivered not only customized products but also integrated solutions tailored to local operating conditions and regulations, establishing itself as a reliable long-term technical supplier.
8.
For mid-to-high-end overseas water treatment and water purification clients, membrane cleaners are far more than generic industrial chemicals. Core evaluation criteria include membrane material compatibility, low corrosion, operating condition adaptability, environmental compliance and customized formulation capability. Conventional manufacturers are constrained by rigid formula systems and limited knowledge of international regulations, making it difficult to satisfy personalized high-end client requirements.
Backed by independent formula R&D capacity, standardized production control and a full international compliance service framework, HiSiaddi resolves client challenges end-to-end from formula customization, performance verification and mass production quality control to complete compliance documentation delivery. The customized solutions deliver cost reduction and efficiency gains for clients, while differentiated comprehensive service capabilities help secure long-term high-end partnerships and build unique supply chain value.
