Hydraspin Oily Water Separation

 

1. What is the problem or need your company has?

During a recent site visit at major mining activities and hydrocarbon pollution prone sites, it is clear that mines are

in dire need of proper infrastructure with regard to drainage and civil structure upgrades; along with a well proven

water treatment technology to separate oil and water that will ensure a low life cycle cost throughout its operations.

2. Why is the problem worth solving?

Solving this problem will result in, clean water, efficient oil water separation operations that will prevent pollution

and ensure that companies act responsibly and meet environmental obligations.

3. What results are important to consider and required by your company for oily water separation technology?

Meeting global standards in oil in water discharge limits is a challenge to all industries. Within the mining sector

this challenge is increased by the necessity to use surfactants and solvent based degreasers. It is crucial to make

use of a powerful separation process such as hydro cyclones that ensures low discharge limits are met. The

system should have a low life cycle cost in terms of maintenance and be simple to operate. Discharge limits of less

than 10ppm have been achieved on mining sites with hydro cyclones. Global targets for mining process water are

usually below 50ppm and below 30ppm for reuse and recycling of wash bay water.

4. What products or services can we offer that will solve the problem and deliver the right results?

We can offer the full range of Hydraspin technology to solve any hydro carbon pollution problem and achieve

 the required discharge limits within budget and specified time frame. Understanding the processes and our comprehensive process design ensure that the right product is provided to meet and exceed our client’s needs.

Types of Oils Hydraspin Removes

Hydraspin deals with all four phases of oil removal namely:

Free Oil – Oil droplets greater than 150 micron

Emulsified Oil – Oil droplets < 150 and > 2 micron

Dissolved Oil – Oil droplets < 2 micron or physically dissolved in water

Solids Coated with Oil – Heavy solids more dense than water. Solids coated in oil

Africa due to its extensive experience in hydro cyclone technologies in the mining- and oil and gas industries

How does the Hydraspin separator work?

Oily water is pumped tangentially into the hydrocyclone which initiates a spinning vortex.

The spinning vortex is accelerated as it moves down the tapered hydrocyclone, separating the heavier water phase to the outside walls while the lighter oil phase moves to the centre.

The separated oil is removed through a reject orifice located in the inlet head section and treated water discharges through the tail section.

Why is it such a powerful separator?

Unlike plate pack style separators the Hydraspin Separator relies on centrifugal force rather than gravitational forces for separation.

The centrifugal force generated inside the vortex of the Hydraspin Separator is of the order of

1,000 times the force of gravity. With such force even emulsified oil droplets can be separated.

How the Hydraspin Oil Skimmer works:

The Hydraspin surface skimmer is one of the most versatile designs on the market.

Made entirely from touch, corrosion resistant stainless steel, the skimmer can deal with a variety of aggressive

liquids at varying depths and concentrations.

•  Waste water treatment
• Storage tanks
• Sewage plants
• Petrochemical processing
• Ponds & lakes
• Airports
• Railway depots
• Sheltered harbours and docks
• Sumps and boreholes
• Manufacturing facilities

Lightweight design – easy one man operation

Adjustable intake weir – skimmer set for optimum efficiency

Tri-float design – provides exceptional stability

Versatile

PROCESS CONDITIONS

Determining oily water separator performance requires careful consideration of all relevant feed conditions. Inlet conditions determine the outlet quality. Our team will advise on approach required to ensure best possible performance.

We look at INLET Design Conditions such as:

Nature of the feed – Hydrocarbons, oil, grease, fuel

Temperature Range – Temperatures higher than 60 ºC lead to improved separation efficiency and cleaner water

Oil Content in feed – Designed to deal with average oil and grease loads of 500-1000mg/L

Detergent types – designed to deal with normally used industrial water based detergents and cleaners

pH range of feed

Other Chemicals and Solids – Strongly emulsifying chemicals such as glycol should not be allowed to enter water streams as can cause emulsification of oil droplets to below 20 micron
