Case Studies / Application Notes

Advanced filtration plant

Problem

A bottled water manufacturer needed to extract water from an additional acquifer which contained medium TDS (salinity) levels.

Solution

Alia was approached via the plant engineer to develop a suitable water treatment plant in treating salinity levels.

A water analysis showed that the moderate salinity levels did not require a reverse osmosis plant and that the salinity could be removed using nanofiltration which would provide the lowest Total Cost of Ownership (“TCO”).

Results

The Manufacturer’s demand for water supply had increased by 50 KL per day which was only to be met by allocating a new groundwater well.
By installing a nanofiltration treatment unit plant, ongoing cost and power consumption would be comparably lower by 30% than using reverse osmosis.

Aeration plant


Problem

Food manufacturer requires Aeration treatment for the treatment of waste disposal and treatment for waste water reuse.

Food manufacturer’s environmental engineer considered a number of options for treating waste water that was high in organic chemicals and oils.

Factory utlilizes 30 KL of water per day in food processing.

Solution

Collaboration between the chief engineer, environmental planners and Alia came to the consensus that aeration treatment combined with distillation would be the best treatment method for the continued management of the factories industrial waste water.  

An aeration modular treatment plant from Alia was employed for the ongoing treatment and removal of organics and oils from the waste water.

The aeration plant was used as a pre–treatment before employing the factories existing distilling process plant.

Result

30 KL of process water is treated daily and recycled for irrigation purposes
Sludge is effectively removed and treated for safe disposal


Arsenic removal plant


Problem

Levels of Arsenic found in public water supply are currently 50 ppb in Bangladesh. Water experts and health authorities worldwide recognize this level of Arsenic in drinking water is far too high for acceptable standards of health.

Health authorities have found that arsenic levels at 50 ppb increased the risk of cancer to one in one hundred people as a direct result of consuming drinking water high in arsenic levels.
Bangladesh has also experienced short term health related reactions relating to circulation and skin damage as a direct result of consuming drinking water high in arsenic levels.

As a third world country water authorities in Bangladesh needed a system for treating arsenic in groundwater that facilitated the available infrastructure and was low in running costs.
 
Approach

Recognizing the problem Alia approached water authorities in Bangladesh offering an appropriate plant to remedy the problem of treating arsenic and other heavy metal loads common in the local acquifers.
Alia were cognizant of the current infrastructure and limitations of the local community in financing the ongoing costs associated with operating a water treatment plant.

Key Deliverables

Alia provided a town with 4 static water treatment plants to treat the daily consumption of 275 KL of groundwater per day.

The Arsenic plant facilitated the limited infrastructure of the local community at a cost that was sustainable by local residents.

Compared to competing technologies most widely used the Arsenic removal plant was able to effectively remove arsenic contained in the catchment water down to 10 ppb and reduce treatment costs by 600% as opposed to competing technologies, making the ongoing use sustainable given the infrastructure and financial capacity of the residents.

Colour removal


Problem

Bottled water manufacturer is finding the transparency of its bottled produce is not as clear as one of its competitors.

Bottled water company felt that it needed to achieve the same standard of aesthetic quality as competitor.
Chief engineer found that the cloudy appearance of the raw water they received was due to higher level of turbidity in water coming from new acquifer the company is drawing water from.

Solution

Alia was approached by chief engineer to advise solution for achieving aesthetic standards of water to be bottled.

Manufacturer retrofitted a colour removal treatment unit plant to provide treatment of raw water to the desired standards of the manufacturer, prior to being bottled.

Results

Bottled water is now manufactured at highest standards of drinking and visual purity.

Front filtration plant

Problem

Rural community in inland Australia has recently allocated a number of groundwater wells to provide municipal water for domestic household use. Recent field testing by environmental lab scientists revealed that the water from the local catchment areas contained medium TDS (salinity) levels and heavy metal contamination. Local water utilities manager initially considered the installation of a reverse osmosis plant to treat the water for domestic town use. Through research of current existing technologies utilities manager felt that reverse osmosis was not the most suitable or cost efficient solution to treating the town’s water.

Solution

Via an environmental engineer, Alia was approached to develop a suitable water treatment plant in treating salinity levels that was both appropriate and cost efficient.

A water analysis showed that the heavy metal contamination was the main concern and was of great risk to the health of the town’s people. Moderate salinity levels however would hinder the removal of metals.
Alia combined an ultrafiltration unit to be used as a pre-treatment in addition to RCO to treat the water matrix of the town’s groundwater.
The combined units would provide the lowest total cost of ownership (“TCO”).

Results

By combining ultrafiltration treatment with RCO, the groundwater extracted from the town acquifers was effectively treated at high efficiency levels to meet the supply demands of the town’s people

Ongoing cost and power consumption would be comparably lower by 300% than the initially proposed use of reverse osmosis also.

High salt correction

Problem

Grape grower allocates a new waterbore to provide water for irrigation. Water is found to be high in metal and salinity content.

Grape grower is cognizant of the fact that water high in metal loads will lead to sulfate acidity in the soils and high salinity will lead to degradation of soils and prevent plants from absorbing soil moisture.
Tests conducted by laboratories indicated very high levels of salinity in the water that would require reverse osmosis to treat.
Grape grower needed a permanent plant which could treat both high levels of salinity and heavy metals.

Approach

Alia provided full end-to –end support for the Grape grower covering licensing, drilling and acquisition of pump and provision of a high salt correction WTP.

Key Deliverables

Grape grower has prevented any costs associated with site contamination due to metals or salinity affecting the soil.
Avoided any cost associated with clearing sprinkler jets which would amount to 240 hrs per year and costing $20,000.
Avoided any inefficiencies in water distribution that would come about due to blocked sprinkler jets.

Ion exchange plant

Problem

Meat processing factory is experiencing ongoing build up of scale in boiler tubes requiring costly maintenance associated with clearing blockages.
Cleaning was also difficult as hardness of water was preventing the lathering of cleaning detergents.
Boiler feed water was found to contain high levels of calcium and magnesium contributing to the build up of scale in the pipes. 20 KL of boiler feed water passes through the factory water pipes each day of operation.

The chief plant engineer recognized that the ongoing labour and costs associated with having to clear water pipes due to lime scale build up could be avoided if a water softening process was implemented to prevent any future build up of limescale.

Solution

Alia provided full end-to-end support with analysis and advisory for the best and most appropriate treatment method for the prevention of limescale buildup.

Chief plant engineer installed an ion exchange plant provided by Alia that could treat the capacity required, and prevent future scale build up in water pipes.

Result

Blockages caused by scale build up reduced to zero.
Labour expenses reduced by over 240 man hours per year.
Return on investment on ion exchange plant was achieved in under 12 months.
Ongoing cost savings estimated to be $185,000 over 10 year lifespan.

Low salt correction

Problem

Rural community in inland Australia has recently allocated a number of groundwater wells to provide public water for domestic household use. Recent field testing by environmental lab scientists revealed that the water from the local catchment areas contained high levels of sodium perchlorate and heavy metal contamination.
Consumption of water containing levels of sodium perchlorate above 0.007 milligrams per kilogram can possibly lead to long term health effects associated with inhibiting the thyroid gland to absorb iodine.

Solution

Water authorities approached Alia to provide a suitable water treatment plant to treat high levels of metal contamination and sodium perchlorate levels found in the catchment water.

Rural authorities implemented a low salt corrections plant provided by Alia to deal with heavy metal contamination and Low mineral salts.

Result

The low salt correction plant was ideal in treating raw water to drinking level standards where metal contamination was effectively treated and additional ion exchange component provided effective treatment for removal of sodium perchlorate.
Ongoing supply of water now meets the standard of the Australian drinking water guidelines.  

Medium salt correction

Problem

Rural community in Inland Australia had constructed a number of waterbores within the local vicinity to provide potable water for domestic and household use.

Water within the acquifers were tested and found to contain medium levels of salt and high levels of iron and manganese. Such high levels of contamination made the water unfit for consumption.

Alia was approached to provide a water treatment plant that could provide total water treatment for the level of contamination found within the acquifers.

Local town required 500 KL per day to suffice the domestic consumption of the local residents.

Approach

Alia provided full end-to-end support in the acquisition of the waterbores as well as pump provision of medium salt correction plants for total water treatment of the groundwater.

Key Deliverables

Groundwater within the local residents is efficiently treated to drinking standards and at low cost.
Return on investment for the medium salt correction plant achieved in just over 12 months.

pH Correction Plant

Problem

Yelliup is a coastal town that was greatly affected by high levels of acid sulfate soils.
A number of issues were prevalent as a result of water and soil containing high acidity levels.

1. Corrosion of infrastructure including the bridges, stormwater drains, building foundations and pipes

2. Marine life was adversely affected killing most of the fish

3. Planning of land use was greatly affected as most of the foundations were unfit for construction.

4. Severe degradation of water in drains, streams, rivers and groundwater

5. High cost of lime treatment for remediation of contaminated site.

The Yelliup site required remediation of 7 km2 of land and treatment of approximately 100 KL of highly acidic water.

Solution

Alia was approached by environmental departments to assist in the remediation of the land and correcting the high acidity levels in the water.

RCO mobile plants were employed for this project as well as mobile pH correction plants.

Lime is the most widely used method of treating pH levels in soils but Alia was confidant that the same pH correction levels could be achieved using Alia chemicals and technologies at a much lower cost.

Results

The combined use of RCO and pH correction employed at the Yelliup coastal project provided total remediation of both the land and the surrounding water catchments.

The cost efficiencies achieved using RCO were considerably high when compared to traditional methods using lime treatment.

The use of Alia pH chemicals also provided the required pH treatment of the Yelliup project at 65% the cost of using traditional lime treatment.
