OUR PRODUCTS & SERVICES

HYDRASPIN

Oil water separation system

Engineering the Power of Nature

HYDRASPIN

Types of oil Removed:

Free Oil – Oil droplets greater than 150 micron.

Emulsified Oil – Oil droplets < 150 and > 2 micron.

Dissolved Oil – Oil droplets < 2 micron.

Solids Coated with Oil – Heavy solids more

dense than water.

HYDRASPIN

How does the Hydraspin Separator

works?

Oily water is pumped tangentially into the hydro

cyclone which initiates a spinning vortex.

The spinning vortex is accelerated as it moves

down the tapered hydro cyclone, separating the

heavier water phase to the outside walls while

the lighter oil phase.

The separated oil is removed through a reject

orifice located in the inlet head section and treated

water discharges through the narrow section.

5

HYDRASPIN

Separation Efficiency of Hydraspin:

95% removal of 10 micron oil droplets.

Other gravity based technologies only removes a portion of free oil.

Industrial process water has a mean particle size of 60-80 micron

due to mechanical and chemical sharing.

Environmental legislation today requires Hydraspin.

13

AHT TOC ANALYZER

Sample from sampling well to glass flow

manifold.

Sample is mixed with

Ortophosphoric acid, which reacts and removes inorganic carbon

compounds.

Inorganic carbon free

sample is then mixed with potassium

peroxodisulphate, which aids

the oxidation of organic carbon to CO2 using ultraviolent activation .

The Air/ CO2

mixture is dried and flows

through the IR detector to detect C02

concentration.

A digital or 4-20 mA output

signal, proportional to

the CO2

concentration is fed via the

Control Circuitry to thecomputer or

server.

PRINCIPLE OF OPERATION

S.A legislation must be revised for the accurate detection of oil & grease
