In the rapidly developing oil and gas, petrochemical, metal processing and automotive repair industries in Qatar, a highly challenging type of wastewater has emerged - a mixture of oil and acid. This type of wastewater is complex in composition and poses significant hazards: the oil causes equipment blockages and affects biological treatment; the acidic substances corrode pipes and damage the biochemical system. Traditional single treatment methods often fall short in addressing both issues and fail to achieve stable compliance and resource recovery. 

As a leading Chinese water treatment equipment manufacturer with over 20 years of experience, BHP Water is specifically designed to handle such complex industrial wastewater. We offer a complete set of customized solutions from the source to the end, ensuring your production is compliant, environmentally friendly, and cost-effective. 

Our "oils and acids wastewater" classification treatment technology chain: 

1. Core pre-treatment - Creaming and oil removal as well as pH adjustment: 

Efficient demulsification and oil-water separation: By using special chemicals and precise air flotation/centrifugal technology, the stable emulsified oil state is completely disrupted, allowing for the efficient separation and recovery of free oil, thus clearing the way for subsequent processes. 

Intelligent pH neutralization system: Automatically and precisely adds neutralizing agents according to the acidity of the wastewater, stabilizing the pH to the optimal range, preventing equipment corrosion and creating conditions for subsequent biochemical treatment. 

2. Core Degradation - For Recalcitrant Organic Matter: 

After pre-treatment, the dissolved organic matter and residual pollutants in the wastewater will undergo deep degradation through our mature "advanced oxidation + enhanced biodegradation" combined process. The advanced oxidation technology can effectively break down the difficult-to-degrade organic chains, improve the biodegradability of the wastewater, and ensure that key indicators such as COD are completely and stably met the standards. 

3. In-depth Processing and Resource Utilization - Achieving Multiple Goals: 

Compliance Emission Module: Through multiple levels of filtration and advanced treatment, the effluent is made clear and can consistently meet the most stringent ASL or Ashghal discharge standards in Qatar. 

Recycled module: Integrating membrane technologies such as ultrafiltration and reverse osmosis, the treated water is purified to meet the standards for recycled water suitable for cooling, flushing, and landscaping, significantly reducing the consumption of fresh water. 

Zero-emission module: For projects with strict requirements or in areas with scarce water resources, ultimately, through the evaporation crystallization technology, nearly zero liquid discharge of wastewater can be achieved, and the crystallized salts can be centrally disposed. 

We have a wealth of successful cases in Qatar and the Gulf region in serving energy and industrial customers. We not only provide equipment, but also offer a full life-cycle service including water quality analysis, process design, equipment supply, installation guidance, commissioning and operation, and training.
