Project Overview

Client Majis Industrial Services SAOC
Location Sohar, Oman
Start-up September 2016
Capacity Waste water treatment: 10,000m3/day (phase1)
Production of recycled water: 7,500m3/day
Plant Description Biological waste water treatment plant of 10,000m3/day capacity and recycle plant (reverse osmosis) to produce 7,500m3/day of process water with very low TDS (less than 25ppm)
Waste water discharged from petrochemical, power, fertilizer, methanol, steel & iron processing plants has to be treated with domestic sewerage.

Current Issues in Oman

Faced Seriously With Customer's Issues

Oman is one of the most water scarce nation in the MENA region with only 416 m3 of water available per person each year compared with 1,429 m3/person/year average in the rest of the region.

Such industries as SIPA houses petrochemical, power, fertilizer, methanol, steel & iron processing plants require cooling and process water for operation 24/7.

Among environmental issues that are currently being addressed, much emphasis has been put on air pollution and liquid discharges.

From January 2014, rules and regulations prohibit discharges of any kind other than brine and cooling water to the marine environment.
This change to the policy implied that the tenants of SIPA currently treating and discharging their waste effluents (treated industrial effluents, TIE) into the return seawater canal for ultimate marine disposal would no longer be able to continue this practice.

Contribution by Our Solutions

Recycling of Effluent Water

Recycling of effluent water is not only effective in reducing the environmental impact of discharges, but also makes it possible to produce water at a lower cost than seawater desalination.

Reliability of Recycling Technology

Compliance with the restrictions on discharging industrial effluent into the marine environment implies water recycling and re-using, and providing reliable and cost-efficient solutions to this issue is a major technical challenge.

Re-use Application

The system ensures that the quality of the recycled effluent meets customers' demand and expectations.
