Containerized Brackish Water RO Plant, 10 m³/h

Overview

How it works

The plant brings feed water through sand filtration, cartridge filtration and chemical dosing, then through the reverse osmosis stage, where membranes remove most dissolved salts. Everything sits inside a 20 ft container with piping, pumps and controls already connected, so on site you connect raw water, product water, concentrate drain and power.

Rated data

At the design condition of 4,000 ppm TDS feed and 20 °C, the plant produces 10 m³/h, which is 240 m³/day if it runs 24 hours. Recovery is 70% and feed flow is 14.29 m³/h. It uses 12 membranes of the 8040 size and works at up to 20 barg. Core equipment is rated at 15.6 kW, excluding the intake pump and air conditioner; installed power including auxiliaries is 30.2 kW. This gives a specific energy of 1.56 kWh/m³ at the design point.

When your water is different

These figures apply to the stated design feed of 4,000 ppm TDS at 20 °C. Colder water cuts output, and a saltier well raises the pressure and the energy used per cubic meter. A different TDS, water temperature or fouling tendency also changes the pretreatment needed, so a full water analysis comes before the quotation. Recovery can be adjusted to your requirement.

Where it is used

Containerized plants suit locations where a building is not available or time is short: remote communities, farms, camps and industrial sites. The container can be moved to a new site later.

Configuration options

• Raw water analysis and target product water standard
• Whether the intake pump and air conditioner are in the supply
• Remineralization or disinfection after RO
• Power supply voltage and frequency
• Concentrate disposal method

Build and delivery

We build and test the plant in our factory and ship it in the container. Our engineers support commissioning and operator training.

Compared with the skid system

This plant packs treatment into a 20 ft container, so it arrives ready to place on a pad and connect. The container holds the electrical panel, pumps and membranes in one weatherproof space, which is a real advantage where the site is remote, dusty or hot.

For smaller demand, such as 1–5 m³/h, the skid system is lighter and costs less to ship. For several times this output, containers are built in larger sizes, or two units can be installed side by side, which also lets one keep running while the other is cleaned.
