New en­gi­neer-and-build wa­ter and waste wa­ter treat­ment and re­cy­cling pack­ages are be­ing in­tro­duced by CST Waste­water So­lu­tions for in­dus­tries and mu­nic­i­pal­i­ties that want to lower the cost and com­plex­ity of such projects.

The de­sign, sup­ply and in­stall pack­ages – in­cor­po­rat­ing global and lo­cally man­u­fac­tured tech­nolo­gies proven in use by some of Aus­tralia and New Zealand’s lead­ing com­pa­nies and coun­cils – are aimed par­tic­u­larly at: • Coun­cils seek­ing en­gi­neer­ing as­sis­tance to de­velop clear choices and op­ti­mum so­lu­tions in­cor­po­rat­ing ad­vanced low-main­te­nance tech­nolo­gies pro­vid­ing high lev­els of wa­ter pu­rity while re­duc­ing main­te­nance, waste han­dling and OH&S is­sues as­so­ci­ated with run­ning them. • In­dus­tries seek­ing read­ily con­structed or por­ta­ble, low main­te­nance so­lu­tions for op­er­a­tions par­tic­u­larly in re­mote, eco­log­i­cally or en­vi­ron­men­tally sen­si­tive ar­eas – rang­ing from re­sources or agribusi­ness de­vel­op­ments in the coun­try or out­back, through to food, bev­er­age, man­u­fac­tur­ing and pro­cess­ing plants shar­ing pre­cious wa­ter re­sources with ur­ban ar­eas. “Rather than pre­sent­ing such or­gan­i­sa­tions with a jig­saw of dis­parate col­lec­tions of tech­nolo­gies and en­gi­neer­ing ser­vices op­tions for them to piece to­gether, our pack­aged so­lu­tions fo­cus on clear, prop­erly en­gi­neered so­lu­tions that de­liver what they prom­ise. CST of­fers turnkey so­lu­tions based on a known raw wa­ter qual­ity and guar­an­tee­ing wa­ter qual­ity out­comes thus giv­ing user en­gi­neers sig­nif­i­cant con­fi­dence in the out­comes and lim­it­ing their ex­po­sure and po­ten­tial con­cerns,” says CST Waste­water So­lu­tions Man­ag­ing Di­rec­tor Michael Bam­bridge.

“There have been ma­jor ad­vances in wa­ter qual­ity, wa­ter re­cy­cling and green en­ergy from waste­water tech­nolo­gies over the last decade, but not all or­gan­i­sa­tions have the in-house ex­per­tise th­ese days to re­alise the ben­e­fits. And whereas stan­dard so­lu­tions might have been good enough when there were fewer pres­sures on wa­ter qual­ity and de­mand on wa­ter as a shared com­mu­nity re­source, to­day wa­ter man­agers have to de­sign to a much tighter and de­mand­ing sus­tain­abil­ity brief,” he says.

Ef­fec­tive tech­nolo­gies are avail­able and proven – in­clud­ing ad­vanced screen­ing, mem­brane and aer­o­bic and anaer­o­bic di­ges­tion, fil­tra­tion and re­verse os­mo­sis for ex­am­ple – but the best com­bi­na­tions “just can’t be picked off the shelf to fit par­tic­u­lar projects. They have to be en­gi­neered for lo­cal con­di­tions or they won’t de­liver on their prom­ise,” said Bam­bridge, whose com­pany’s projects range from wa­ter qual­ity plants for coun­cils through­out Aus­tralia to green en­ergy gen­er­a­tion and wa­ter re­cy­cling plants for or­gan­i­sa­tions such as the Blue­tongue Brew­ery, Ca­dia min­ing, Fru­cor, Golden Cir­cle and na­tional dairy, pa­per and agribusi­ness com­pa­nies.

Lo­cally man­u­fac­tured tech­nolo­gies – such as fine screen­ing, for ex­am­ple – are al­ready re­duc­ing main­te­nance and OH&S is­sues for Aus­tralian and New Zealand com­pa­nies, while CST Waste­water So­lu­tions also rep­re­sents glob­ally suc­cess­ful tech­nolo­gies in­clud­ing Smith and Love­less, Ber­son UV dis­in­fec­tion sys­tems and Global Wa­ter En­gi­neer­ing wa­ter qual­ity and green en­ergy tech­nolo­gies proven in more than 300 projects world­wide. One GWE pro­ject re­cent won a global award from the In­sti­tu­tion of Chem­i­cal En­gi­neers, IChemE, which rep­re­sents more than 40,000 en­gi­neers glob­ally. GWE wa­ter qual­ity tech­nol­ogy – which ex­tracts green en­ergy from waste wa­ter to turn a prob­lem into a profit – is cur­rently be­ing de­ployed by the lead­ing Ja­panese meat pro­ces­sor NH Foods at Oakey Beef Ex­ports in Queens­land. The Oakey pro­ject not only rad­i­cally im­proves waste wa­ter qual­ity but also gen­er­ates bio­gas (methane) to re­place fos­sil fu­els and lessen en­vi­ron­men­tal im­pacts.

An­other ad­vanced tech­nol­ogy, high ef­fi­ciency SFC fine screen­ing ex­trac­tor tech­nol­ogy, is cur­rently de­liv­er­ing low main­te­nance per­for­mance with re­duced OHS haz­ards for mu­nic­i­pal and in­dus­trial waste wa­ter schemes. This tech­nol­ogy, which also re­duces han­dling of waste, is demon­strat­ing im­me­di­ate re­sults in one of its re­cent ap­pli­ca­tions, for the co-joined towns of Har­den and Mur­rum­bur­rah, where it is in­cor­po­rated into the treat­ment sys­tem im­prov­ing wa­ter qual­ity for a pop­u­la­tion of ap­prox­i­mately 2,000 peo­ple.

“Many com­mu­ni­ties and in­dus­tries – es­pe­cially through­out re­gional and out­back ar­eas of Aus­tralia - face wa­ter qual­ity and re­cy­cling is­sues brought about by drought and lim­ited wa­ter re­sources avail­able for drink­ing, agri­cul­ture, prod­uct pro­cess­ing and shar­ing be­tween com­mu­ni­ties and their in­dus­tries.

“Some such groups have lim­ited ac­cess to the tech­ni­cal re­sources, tech­nolo­gies and ap­pli­ca­tion know-how to pro­duce so­lu­tions to their is­sues, which is where pack­ages such as we have in­tro­duced can be in­valu­able.”

CST Waste­water So­lu­tions en­gi­neer­ing team has a track record of more than 25 years suc­cess­ful pro­ject im­ple­men­ta­tion to back its new de­sign, sup­ply and in­stall pack­ages.
