Evaporator Treatment

EVAPORATOR TREATMENT
Liquid Evaporator Treatment for Evaporators

PRODUCT DESCRIPTION
A Polymer- based additive to be used in Evaporators to
prevent Scale Formation

DIRECTIONS FOR USE
EVAPORATOR TREATMENT is a liquid based on a low
molecular weight polyacrylate which inhibits the
formation of carbonate and sulphate scale deposits. In
addition EVAPORATOR TREATMENT will inhibit the
deposition of precipitates by keeping them dispersed
and conditioned to be removed by blowdown.
EVAPORATOR TREATMENT remains stable at high
temperatures and does not hydrolyse & become
ineffective.

DOSAGE
The standard dosage applicable to the majority of
systems is 0.030 (30ml) litres of EVAPORATOR
TREATMENT per Tonne of distillate produced. This is
based on the rated production capacity of the
evaporator.
The treatment is added to the dosage tank & dosed at a
rate satisfactory to the flowmeter.
The brine density should not exceed a density of 1.038.
The scaling potential increases rapidly over this level.
An increase in the amount of EVAPORATOR
TREATMENT used will assist in retaining potential
scale forming salts in suspension.

DOSING METHOD
Via the dosage tank. The dosing point may vary with
type and make of evaporators. As a general rule, the
EVAPORATOR TREATMENT should be dosed into the
sea feed line before entering the heater.
