Founded in January 2003, by Tony Robles, the Overall Responsible Operator (ORO) at Kirkland Lake Water Treatment Plant (WTP), AlumCAS is the only nano-polymer flocculent available in the market. With proven use in municipal and industrial processes, AlumCAS is a replacement for current flocculants in use. After 70 years of prior art research and development in the production of Activated Silica, Tony Robles, the inventor of AlumCAS has solved the problem of producing a non-toxic, silica based nano polymer in the volume required for worldwide water treatment operations. Surpassing the capabilities of alum, poly aluminum chloride with or without organic polymers. AlumCAS is the GAME CHANGER in worldwide water treatment.

Since 2003, AlumCASTM has been in use successfully, with positive results that have exceeded expectations.

AlumCASTM was invented as a result of the changing and strict regulations in the potable water and wastewater (both municipal and industrial) fields.  Current market products are not always capable to meet these strict new demands;  AlumCASTM exceeds the regulations with many complementary benefits as well.

The Background

In 1993 while working as a water treatment operator at Kirkland Lake Water Treatment Plant (WTP) in Ontario Canada, Tony Robles was presented with a unique challenge:  The provincial government mandated Kirkland Lake WTP to comply with Disinfection Byproduct Limits of 100 μg/L Total Trihalomethanes (TTHMs).

  • The WTP's primary chemical coagulant was Alum with Activated Silica as the coagulant aid.  With this combination of chemicals, the average level of TTHMs was significantly over the regulatory limits.

Faced with a limited budget, Tony Robles, developed a new formulation and manufacturing method of activated silica called AlumCAS™ to bring the water treatment plant into compliance.

  • Using Alum as the primary coagulant and AlumCAS™ as the coagulant aid, the water treatment plant TTHMs are reduced to an average of 60 μg/L, well below the provincial mandate of 100 μg/L and below the EPA limit of 80 μg/L.  At the end of the day, the invention saved the municipal government significant capital expenditures.

Additionally benefits experienced at the WTP through the use of AlumCAS™ included:

  • Increased removal of organic matter (NOM) resulting in a ~30% reduction in Chlorine use
  • Ability to run the plant at designed capacity which was a 50% increase in throughput compared with using the old activated silica formulation.

AlumCAS™ is currently under patent protection in numerous countries

The word AlumCAS™ is composed of the word 'Alum' which is a popular water treatment coagulant and the acronym 'CAS' pronounced 'Kass' which stands for 'Cationic Activated Silica'.
