What information do you need to size a seawater RO or industrial water treatment system?

Send a recent raw water analysis (TDS, conductivity, hardness, silica, iron/manganese, SDI or turbidity, oil and suspended solids where relevant), feed water temperature range, required product water quality and daily capacity, target recovery, available power supply (voltage/frequency), site conditions and whether you prefer a skid or containerized layout. With this data our engineers prepare a process design, mass balance and equipment list.

How fast can a containerized seawater desalination plant start producing water?

Tongjie containerized seawater RO units are fully prefabricated, assembled and tested in our Shanghai factory before shipment. On arrival the unit only needs basic power, intake and product water connections, so commissioning is short and predictable, which suits emergency supply, remote islands, construction camps and decentralized permanent supply.

Can your oil and gas produced water system meet reinjection requirements?

Yes. The system combines oil removal, softening, disc tube reverse osmosis (DTRO) and concentration. Treated reinjection water reaches oil content of 5 mg/L or less and suspended solids of 1 mg/L or less, enabling zero-discharge reuse of fracturing flowback. The skid-mounted container design can be commissioned within about 15 days and supports unmanned operation with remote monitoring for sites such as the Middle East and Kazakhstan.

Do your pharmaceutical purified water systems support validation?

Our pharmaceutical water systems use pretreatment, precision filtration, RO and EDI, and are built to pharmaceutical engineering practice with online monitoring of conductivity, temperature and flow. Data is recorded and traceable, and documentation is prepared to support your validation and qualification activities.

Do you offer ODM/OEM water treatment equipment?

Yes. We supply ODM/OEM membrane systems for distributors, EPC contractors and equipment brands, including customized capacity, materials, control systems, container layouts, labeling and documentation.

Which certifications and qualifications does Tongjie hold?

Tongjie holds CE certification and ISO 9001, ISO 14001 and ISO 45001 management system certifications. The company is a National High-Tech Enterprise and Shanghai Specialized & Sophisticated Enterprise, holds Class II contracting qualifications in environmental protection engineering and in mechanical and electrical installation, and owns more than 38 invention and utility patents plus software copyrights.

Product Description

Our Solution

Shanghai Tongjie Environmental Protection's oilfield produced water treatment system is specifically designed for oilfields in the Middle East, Kazakhstan, Xinjiang, and other regions. It employs a full-process technology comprising "pre-treatment (oil removal/gas flotation) + softening + ultrafiltration + DTRO high-pressure reverse osmosis + concentrate concentration." The influent contains ≤5000 ppm oil and ≤150,000 ppm TDS; the treated reinjected water meets standards (oil content ≤5 mg/L, suspended solids ≤1 mg/L), achieving zero discharge and reuse of fracturing discharge fluid. The system features containerized modular design with factory prefabrication and commissioning, enabling on-site operation within 15 days.

FAQ

Can high oil content (5000 ppm) be treated?

Through multi-stage air flotation combined with coalescence oil removal, the oil concentration is reduced from 5000 ppm to ≤5 mg/L, ensuring stable compliance with standards.

Is it suitable for desert environments with extreme temperatures?

It withstands temperatures up to 55°C and down to -30°C, features dust and sand resistance, and is explosion-proof, making it ideal for extreme oilfield conditions.

Can the system operate without human supervision?

With fully automatic operation, remote monitoring, and fault early warning capabilities, it enables unmanned operation, significantly reducing maintenance costs.

Is system scaling severe?

With chemical softening, anti-fouling membrane, and online cleaning, the scaling risk is reduced by 80%, ensuring long-term stable operation.

What is the standard processing capacity of the system?

The system is highly customizable, with standard capacities ranging from 100 to 5000 tons per day to meet various project requirements.

How long does it take to deploy the system on-site?

Thanks to our containerized modular design and factory pre-commissioning, the system can be fully operational on-site within 15 days of arrival.
