Equipment Coverage Across the Full Water Treatment Process Chain

We supply reverse osmosis systems, water softeners, pre-treatment filtration, sterilization and disinfection equipment, wastewater treatment equipment, parts and accessories, and water storage and supply systems from one certified manufacturing base holding CE, ISO 9001, and ASME certifications. When we review a multi-stage inquiry, our engineering team assesses the full process chain as a single configuration sequence: pre-treatment load against membrane or softener requirements, followed by sterilization and storage sizing. Each upstream stage directly affects the specification for the next, so sourcing pre-treatment, membrane, and storage equipment from separate industrial water treatment systems manufacturers can create gaps in flow capacity, pressure rating, or material compatibility before production commitment is made.

Pre-Quotation Engineering Review

What we confirm before quotation.

Standard inquiries get a configuration scope, not an SKU dump. Each family has a defined review path against your source water & application — values below are preliminary design targets; final limits depend on source conditions and order-specific review.

Application Paths

Inquiry Routing by Source Water Type, Application, and Output Target

As water filtration equipment manufacturers with a certified production base in Qingdao, we configure each system to match your source water profile and output target. Before selecting equipment, our engineers review your water analysis report, daily flow requirement, and application type to confirm which treatment stages apply and in what sequence. Select your industry below.

Skid-mounted BWRO with Pre-treatment — Food Processing Plant, Vietnam

Client Challenge

The buyer drew from a municipal supply at 430–480 mg/L TDS with variable turbidity peaking above 15 NTU during wet season. Two previous locally-sourced RO systems had experienced membrane fouling within 90 days — both lacking adequate pre-treatment. The client required consistent permeate at or below 10 mg/L TDS sustained over a full production year without membrane replacement.

System Configured & Delivered

After reviewing the water analysis and 8 m³/h output requirement, we configured: multimedia sand filter → 5 μm cartridge → single-pass BWRO at 75% recovery. Factory-assembled, pressure-tested, and flushed before crating. Shipped in one 20 ft container with CE declaration, mechanical and electrical drawings, and a commissioning guide. Lead time: 28 working days.

“The system arrived pre-assembled and pressure-tested. Our technician commissioned it in less than two days. We have been running it for eight months with no fouling issues and permeate quality consistently at 8–9 mg/L TDS.”

Duplex Ion Exchange Softener — Industrial Steam Boiler Line, Saudi Arabia

Client Challenge

Source hardness measured consistently at 300–340 mg/L as CaCO₃. Scale accumulated on heat-transfer surfaces within six weeks of each manual descaling cycle, cutting boiler efficiency and increasing downtime. The client required outlet hardness reliably below 5 mg/L and continuous boiler feed — switchable to regeneration mode without interrupting supply — operable by a single non-specialist operator.

System Configured & Delivered

Duplex parallel-valve ion exchange softener with time-clock regeneration: one vessel in service while the second regenerates, guaranteeing uninterrupted feed at 5 m³/h. Vessel sizing confirmed for a minimum 48-hour service cycle. OEM-labelled to distributor specification; shipped with regeneration manual, brine startup guide, and initial food-grade salt supply. Outlet hardness verified at 0–2 mg/L in factory test before release.

“Ten months with zero scaling incidents and no unplanned boiler maintenance. Regeneration is automatic and the documentation covered everything — our local engineer did not need to contact Hiju once after installation.”

Factory & Engineering

28 Engineers and 78 Technicians in a 21,000 sqm Workshop

We have been manufacturing and exporting water treatment equipment since 2016, operating from a 70,500 sqm facility in Qingdao that includes a 21,000 sqm production workshop. Our production lines cover process water purification, pre-treatment filtration, and wastewater treatment equipment for industrial reuse and discharge applications. We hold CE and ISO 9001 certifications; ASME documentation is available on request depending on product type and destination. As a water treatment plant manufacturer focused on export, our engineering team includes 28 engineers who manage system selection, configuration review, and technical documentation, supported by 78 production technicians responsible for fabrication, assembly, and quality inspection.

Hiju 21,000 sqm production workshop with water treatment equipment assembly

When a buyer submits an inquiry that includes a water analysis report and a defined daily output target, our engineers check source TDS, hardness, suspended-solids load, flow requirement, and destination electrical standards before confirming whether a standard unit or a customized configuration applies. We do not issue a system recommendation without this review; inquiries that arrive without source water data usually require an additional technical exchange before any meaningful configuration can be generated, and we ask for it upfront to avoid that delay; for our full manufacturing and engineering background, see our About Hiju page.

Step · 01
