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

Acid Solutions Pty Ltd unique patented CRAB™ systems require substantially less equipment, support infrastructure and installation time, ensuring that our client’s time and cost needs are satisfied.
CRAB™ patented systems are unique because of our highly efficient mixing, blending and application processes.
Acid Solutions systems provide safe and accurate reagent application ensuring peace of mind for sensitive sites.

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

CRAB™ systems will precisely blend and process many powder, granular and liquid reagents in combination, with outputs from 600 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 "

Combining reagents to save you money

Many specialises reagent supply companies mix basic chemicals into their proprietary treatment products and then sell them on to the client in pre-prepared bag or liquid form. Most reagents used by the CRAB™ systems are common and off the shelf.
Acid Solutions systems 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.

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. Let Acid Solutions configure the best reagent combinations and process to efficiently and safetly treat your water problem at the lowest possible cost.

CRAB™ treatment systems

Durability and compact size make these machines great for a multitude of difficult on-site treatment applications.
CRAB™ systems can provide the mobility required for a fast 1 day remediation and can also be used for specialised multi process high quality long term treatments.
Designed usually as mobile machines, these systems can be quickly and easily placed in multiple positions throughout your site to provide a range of treatment uses with the CRAB unit where ever required.
Acid solutions specialised application accessories enlarge the range of treatment capabilities to help draw even more benefit from the CRAB™ systems. Acid Solutions design and engineering team can specifically adapt these systems to achieve your precise water treatment outcomes.
CRAB™ multi purpose systems can be self powered and are available in 3 sizes depending on reagent output and capability required.

• CRAB CX500 - This highly accurate CX500 CRAB processes small to medium reagent outputs from 600 grams up to a ¼ of a tonne per hour with the same automation and control of the larger systems. It weighs 440 kg, is 1650mm long, 650mm wide and 950mm high.
• CRAB CX750 - This is our multipurpose machine. The CX750 can process up to 900 kg/hr of hydrated Lime and weighs 720 KG. It is 2200mm long, 900 wide and 1200 mm high and require less than 14 amps 240 Volts.
• CRAB CX1500 - This is the largest of our units to date, designed to handle the most extreme of reagent requirements and demands. It weighs 1650 kg and 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 being only 3.05 metres long.

Control Capabilities and Safety Systems

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.
Autostart, automatic safety shutdown, datalogging, pH correlation and alerting provide security for environmentally sensitive treatment operations.

Design, construction & quality

All CRAB™ systems are constructed from laser cut stainless steel to provide long life and corrosion resistance in the most extreme of acidic, alkaline and salt water conditions.

All motors, gearboxes and pumps have been chosen for their ability to withstand harsh industrial operation so treatment operations are not interupted in case of breakdown.
A range of power supplies are used from Generator to single phase or 3 phase connection or a combination for use in mains supply and portable situations. The CRAB™ systems model CX 750 requires only 12 amps 240 volts.
All CRAB™ systems have Mines Approved Electrics. A fully sealed and water cooled processor control housing provides protection against the hot, humid and corrosive environments these machines are used in.
All systems are Australian Standards Compliant, so you're assured of receiving the ultimate in quality efficiency design and safety.
The latest in capability & technology whilst maintaining operational simplicity.
