Acid drainage water treatment

C.R.A.B. Water Treatment Technology

Acid Solutions Pty Ltd presents The Leading Technology for bulk water treatment ...
The CRAB™ - Calibrated Reagent Applicating Blender

Our patented CRAB™ and modular application systems require substantially less equipment, support infrastructure and installation time, ensuring that our client’s time and cost needs are satisfied.
Acid Solutions systems provide safe and accurate reagent application ensuring peace of mind for sensitive sites. CRAB™ patented systems are unique because of their highly efficient mixing, blending and application processes fully controlled by a specifically designed time proven computer processor.

The latest in capability & technology with an extremely short installation time.

CRAB™ treatment systems

CRAB™ systems provide the accuracy required for specialised multi process high quality long term remediation and are also used for fast 1 day treatments.
Mobility and compact size make these machines great for a multitude of difficult on-site treatment applications. This modular design makes them quick and easy to install in difficult to access locations while providing a broad range of treatment capabilities.
We use 3 sizes of the CRAB™ multi purpose system depending on reagent output and capability required.

  • CRAB CX1500 - This is the largest of our units to date, designed to handle the most extreme of reagent requirements and demands. It has an enormous output of up to 4400 Kilograms per hour. This CRAB will accurately process a 500 kg bulk bag of hydrated lime in less than 8 minutes and is extremely compact for its capability.
  • CRAB CX750 - This is our multipurpose machine. The CX750 can process up to 900 kg/hr of hydrated Lime and requires less than 14 amps 240 Volts.
  • CRAB CX500 - This highly accurate CX500 CRAB processes small to medium reagent outputs from 600 grams up to a 1/3 of a tonne per hour.

Power, Control Capabilities and Safety Systems

All CRAB™ systems are usually self powered but can be connected to mains power if available.
All systems have Mines Approved Electrics and are Australian Standards Compliant, so you're assured of receiving treatment services with safe and compliant machinery.
Two unique Solid State Processors have been custom designed to control the CRAB™ systems with precision and automated safety. These advanced control capabilities are used to compliment your treatment requirements and provide the precise control, accuracy and WPH&S requirements.
26 site programmable parameters, Autostart, automatic safety shutdown, datalogging, pH correlation and alerting provide security for environmentally sensitive treatment operations.

Water treatment and Environmental Safety

Not only can contaminated water harm the environment, but so can certain treatments, reagents and methods of application. Acid Solutions has designed many reagent combinations and application processes to protect environmentally sensitive sites such as swamps, wetlands, aquatic waterways and marine environments. These processes along with the correct reagents and accurate application provide unprecedented safety for sensitive sites.

CRAB™ systems accurately process many chemicals and reagents
in either powdered, granular or liquid form including:

Hydrated Lime Alum Activated Carbon
Gypsum Soda Ash Magnesium Hydroxide
Aglime Calcium Peroxide Sodium/Calcium Bicarbonate
Zeolite Sodium Hydroxide Magnesium Carbonate
Flocculants Ferric Chloride Ferric Sulphate
Oxidizers Hydrogen Peroxide Potassium Permanganate
Coagulants Chlorine Catalysts
Sodium Aluminates Poly Aluminium Chloride Bacteria Impregnated carriers

CRAB™ systems will precisely blend and process many powder, granular and liquid reagents in combination, with outputs from 1500 grams per hour to 4.4 tonnes per hour.
CRAB™ feed systems have been designed to accept 20-25 kg handy bags, 500 to 1200kg bulk bags or automatic correlated external silo feed.

"One of our specialties is the accurate application of hydrated lime {CA(OH)2 Calcium hydroxide} which is one eighth the cost of the liquid alternative Caustic soda {NaOH Sodium hydroxide}, the savings that can be realised are significant "

Jason Beath - Acid Solutions Pty Ltd Managing Director

Combining reagents to save you money

The Acid Solutions team produce excellent results by combining mixes of liquid and powdered reagents onsite within the mixing and application process which greatly reduces costs to the client.
A common example would be liquid ferric chloride and powdered hydrated lime, which when mixed in the right combination produce ferric hydroxide which is a great mop for many toxic dissolved metals.
Combining reagents such as these on-site can produce outstanding results without the extreme costs of using proprietary reagents. Many different combinations of Hydroxides, carbonates, neutralizers, oxidizers, flocculants and absorbents can produce unprecedented results. Let Acid Solutions configure the best reagent combinations and process to efficiently and safetly treat your water problem at the lowest possible cost.
