Advanced Oil-Water Separation: The Tank-within-Tank System Revolutionizes Oily Wastewater Pretreatment.

Amidst increasingly stringent environmental regulations worldwide, the treatment of industrial oily wastewater has become a crucial issue for industries such as petroleum, chemical, machinery, and food processing. Traditional settling tank treatment methods often suffer from low efficiency, complicated operation, and frequent shutdowns for oil and sludge removal.

Qingdao Brator Environmental Protection Technology Co., Ltd., leveraging years of technological accumulation and practical experience, has successfully launched the GZ-XX type tank-within-tank equipment. This system integrates regulation, sedimentation, oil removal, and sludge discharge, completely solving the operational problems of traditional equipment and becoming an innovative tool in the field of oil-water pretreatment.

What is the tank-within-tank?

The tank-within-tank system is a highly efficient, modular oil-water separation pretreatment system. It consists of an outer tank (wastewater equalization tank), an inner tank, a cyclonic separation oil recovery and discharge unit (including a three-phase hydrocyclone separator and a free oil collector), and associated piping.

Its core principle utilizes the density difference between oil and water, employing fluid dynamics and centrifugal separation technology to achieve efficient three-phase separation of oil, water, and sludge. This system is not only compact and easy to operate, but it can also perform oil recovery and sludge discharge without interrupting operation, significantly improving treatment efficiency and equipment utilization.

Key Advantages & Stable Performance.

1. Efficient Oil Removal and Stable Effluent Quality

Even with influent oil content as high as 10,000 mg/L, the treated effluent oil content can be reduced to below 200 mg/L (excluding emulsified oil), fully meeting the influent requirements of subsequent treatment units.

2. Continuous Operation, Zero Downtime

Unlike traditional settling tanks that require process shutdowns for cleaning, our system enables simultaneous oil recovery and sludge discharge during normal operation, ensuring maximum productivity.

3. Low Water Content in Oily Sludge, High Recycling Value

The collected oily sludge has a low water content, facilitating subsequent recycling or treatment and reducing disposal costs.

4. Simple Structure and Reliable Operation

The equipment has no internal moving parts, resulting in a low failure rate, simple maintenance, and long-term stable operation.

5. Strong Adaptability and Wide Application

Suitable for various types of oily wastewater, including those from petrochemical, machinery processing, and food processing industries. Water quality fluctuations have little impact on its treatment effect.

Brief Introduction to the Working Principle

After the oily wastewater is pumped into the equipment, it first passes through a three-phase hydrocyclone separator. Under the action of centrifugal force, the oil phase floats and collects in the oil storage area, the water phase enters the clean water area through the water collection pipe inside the middle tank wall, and the solid particles settle to the sludge area.

Each phase is discharged through dedicated pipelines:

Oil phase → Waste oil tank

Water phase → Subsequent treatment unit

Sludge → Sludge tank

The entire process is highly automated and easy to operate, requiring only periodic inspections and manual oil and sludge discharge.
