Screening

A large truck washing company was having problems with sludge accumulation in its source water pits that it was using for vehicle wash-down. This sludge accumulation was so high that it was reducing its water storage capacity and thus impacting on operations. MAK Water was asked to review the operation and recommend a long-term solution that reduced its ongoing costs whilst resolving its current water storage issues.

A large mining company approached MAK Water as their mine site was plagued with ongoing issues surrounding unscreened wastewater entering their sewage treatment plant. Increased maintenance requirements and premature failure of downstream equipment motivated the mining company to reach out to MAK Water – The Smart Water People with a documented history of providing effective wastewater solutions. MAK Water proposed a solution to screen the wastewater and effectively treat the source water by removing all solids less than 2mm eradicating equipment failure downstream and meeting the client’s key requirements of affordable, low maintenance and turnkey solution.

One of the largest bottlers of non-alcoholic ready-to-drink beverages in the Asia-Pacific region was having problems with its Wastewater Treatment Plant (WWTP) that was used to treat their factory waste prior to discharge to the local water authority.  The plant was unreliable, required excessive operator input, which combined with its high chemical consumption made it expensive to run. MAK Water was asked to review the operation and propose a solution, to reduce the solids going into the process through better screening, reduce chemical consumption and operator input and improve the quality control of the treated water.

A northern NSW regional Council was seeking to upgrade their sewage treatment plant inlet works by replacing an old grit classifier that was reaching end of life. Council required a like for like replacement in order to minimise modifications to their existing infrastructure and to simplify installation and commissioning. Key requirements included for the replacement grit classifier to have an easily replaceable liner and an automatic bagging system to capture dewatered solids and minimise odours.

A northern NSW regional Council was seeking to upgrade their sewage treatment plant inlet works by replacing an old step screen that reached end of life. The Council was initially seeking a like for like replacement, however, wanted better removal efficiency and a solution that required minimal maintenance and operator input in day-to-day use. Key requirements included the ability to retrofit the new screen into the existing concrete channel to minimise site modifications, and incorporated screenings compaction and washing.

A pet food manufacturing facility in Western Sydney wanted to replace an ageing rotary drum screen due to poor screening performance leading to issues with a Dissolved Air Floatation process downstream. They also wanted to replace an existing screenings Screw Compactor that did not provide sufficient dewatering and used too much potable water for washing. MAK Water was engaged to provide a solution. We delivered an integrated and compact replacement to fit into the existing plant room with minimum impact to operations.
