CONFIGURATION OF NEUTRA-MILL WATER TREATMENT SYSTEMS

Earth Systems' Water Treatment systems are scaled to your requirements from off-the-shelf systems to more sophisticated custom-built, remotely-monitored integrated treatment systems. These units can be easily coupled with a purpose designed reagent storage and delivery systems. We develop the solution to satisfy your treatment needs.

OFF-THE-SHELF SYSTEMS

The off-the-shelf systems include land based or water based models allowing significant flexibility in providing cost effective water treatment solutions. Some examples of "off-the-shelf" systems include:

A. Multi Purpose Neutra-Mill - suitable for many water treatment applications, including treatment of acid mine drainage.

Details

B. Turbidity Mill - designed to efficiently and rapidly remove turbidity and suspended solids, can also dispense other reagents (biological media, adsorptive clays) throughout the upper layer of a water body. Used at minesites and for potable water.

Details

C. HALT System - (under development) - designed to utilise low-cost limestone aggregate for the treatment of acidified drainage (eg. replacing anoxic limestone drains), suitable in areas affected by acid sulphate soils and acid rain.

CUSTOM-BUILT INTEGRATED TREATMENT SYSTEM

Many water treatment requirements are typically application-specific. Earth Systems can design and construct an integrated treatment system to suit your specific site requirements. An integrated treatment system generally consists of three main components:
Reagent storage and delivery - options range from 1 tonne bulker bag dispensing systems with portable augers to 20 tonne storage silos with auger or belt feed systems.
Chemical mixing and dispensing - component designed for your output and reagent requirements.
Control and monitoring - options from manual on/off to radio telemetry SCADA control systems.

We develop your actual site treatment requirements onsite with you. This ensures that the treatment plant is integrated with your site operations and accounts for the chemistry of your water.

Applications
Acid neutralisation, pH control, toxic metal reduction, turbidity and suspended solid reduction, dispensing biological or adsorptive media, nutrient control, blue green algae management, odour control

Optional Specifications

Model IS-5 - Land based
General Description
The IS-5 is an integrated treatment plant that combines a reagent storage and delivery system (15TM5/5) with an off-the-shelf treatment system (0710/1717). An interlocked, automated control system seamlessly links these two units so that maximum control is given to the operator.

The IS-5 facilitates the automated mixing of dry reagent to produce a concentrated solution or slurry, which can be dispensed directly into the water body or stream requiring treatment. This supplants the approach of conventional systems which pump the entire water body requiring treatment through the treatment plant.

The IS-5 is designed to be easily portable and only requires minimal site preparation prior to installation. As the conditions change at a site the IS-5 can be easily relocated to accommodate changing site demands.

The IS-5 provides a simple method for conducting routine and unmanned treatment of surface waters at mine sites.

Primary Applications
Acid neutralisation, pH correction, toxic metal reduction, lowering total dissolved solids, turbidity and suspended solid reduction.

Secondary Applications
Colour removal, control of nutrients, dispensing biological or adsorptive media.
