Appropriate wastewater management plays a crucial role in sustainable development.

Wastewater treatment plants consume large quantities of energy. Modern and innovative treatment technologies can help to significantly reduce the energy demand, up to achieving energy-neutral plants. As a result, operating costs are minimized which has a positive effect on cash flow and economic success of producing companies. WABAG is an expert in resource-saving treatment plants by promoting sustainable water recycling concepts and closed water cycle systems as well as customized, energy-optimised treatment processes and intelligent automation systems

Upstream Produced Water

Water is the most critical element in Oil & Gas Exploration and Production. The main challenge of water treatment in the upstream sector is to reduce its environmental footprint and develop efficient water treatment solutions for reuse or discharge. Whether it is for Enhanced Oil Recovery (EOR) or chemical EOR, for reuse or discharge, water availability and purity is crucial. The water treatment process has to meet requirements related to the specific characteristics of the site as well as those related to local environmental legislation. For EOR or Injection purposes, water treatment processes differ depending on the external water resource available and on the water quality required by the site e.g., solids, sulfate and salinity. Moreover, the treated water must not cause corrosion or decreased of oil production.

Downstream Process Water

Faced with increasing environmental legislation coupled with increasing pressure to reduce operational costs while cutting back on investments, the refining and petrochemical industry needs to optimize and diversify water resources. Cooling water and utility water are most often pre-treated water from external water sources (seawater, river water, lake or potable water) but can also be produced by reuse or recycled treated wastewater. The required water quality depends on the specific use within the site. Various forms of utility water may be needed including: process water, boiler feed water, potable water, firefighting water, tank cleaning water.

Downstream Wastewater

Each refinery or petrochemical complex has a specific wastewater composition based on the production capacity and the products. Today we can say that wastewater is the unique fingerprint of each site. In areas where water is scarce , clients may choose (partial) recycling of treated wastewater or even go all the way to Zero Liquid Discharge (ZLD) plants in order to minimize the cooling of utility water intake from natural resources. Reusing & recycling also helps with regulatory compliance, protects environment and optimizes the water balance.
All water and wastewater treatment plants generate large quantities of chemical and biological sludge that have to be managed. In many locations sludge handling represents up to 30 or 40% of the plant’s operational costs. Once treated, oil can be recovered and sludge can become a product and be used for energy recovery systems.
